You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Which suppliers do we have in Toulouse?

[Assistant]
To answer the question "Which suppliers do we have in Toulouse?", I need to identify the entities related to suppliers and the location Toulouse in the knowledge graph. Then, I will find the relationship between suppliers and the location Toulouse.

Step 1: Search for the entity "Toulouse" in the knowledge graph to get its identifier.
Step 2: Search for entities related to "supplier" to understand how suppliers are represented.
Step 3: Find the property that links suppliers to locations.
Step 4: Query the suppliers that are linked to Toulouse.

I will start with Step 1 and search for the entity "Toulouse".

[Tool] No entity items found

[Assistant] I could not find an entity for "Toulouse" in the knowledge graph. I will try to search for entities related to locations or cities to see if Toulouse might be represented differently or under a broader category.

[Tool] No entity items found

[Assistant] It seems that there are no entities related to cities or Toulouse in the knowledge graph. I will now try to search for entities related to "supplier" to see if there are any supplier entities in the knowledge graph.

[Tool]
Top 10 entity alternatives:
1. Supplier (pv:Supplier): The Supplier of some item(s).
2. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier

[Assistant]
I found an entity "Supplier" with the identifier pv:Supplier and a property "supplier" with the identifier pv:hasSupplier that relates a product to a supplier. Now I need to find how suppliers are linked to locations or addresses.

I will search for properties of the entity pv:Supplier to find any property related to location or address.

[Assistant] There are no direct properties related to location for the entity pv:Supplier. I will try searching for properties related to address or city for the entity pv:Supplier.

[Tool]
Top 10 property alternatives:
1. label (rdfs:label)
2. comment (rdfs:comment)
3. type (rdf:type)
4. depiction (foaf:depiction)
5. is Defined By (rdfs:isDefinedBy)

No other items found

[Assistant] There are no properties related to address or city for the entity pv:Supplier. I will try to find any property related to location or address in the entire knowledge graph to see if there is any property that might link suppliers to locations.

[Tool]
Top 10 property alternatives:
1. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
2. price (pv:price): The price specification of a product., has domain Product, has range Price
3. name (foaf:name):

4. name (pv:name): The name of something.
5. lat (wgs84:lat)
6. phone number (pv:phone): has domain Agent, A phone number.
7. address text (pv:addressText): The address text., has domain Agent
8. address locality (pv:addressLocality): The address locality (city)., has domain Agent
9. range (rdfs:range)
10. member of (pv:memberOf): The department to which an agents belongs., has range Department, has domain Agent

[Assistant]
I found some relevant properties that might help:
- pv:country (domain Supplier, range Country)
- pv:addressText (domain Agent)
- pv:addressLocality (domain Agent) which is the address locality (city)

Since suppliers might be a type of Agent, I will check if pv:Supplier is a subclass or type of Agent. I will look for triples where pv:Supplier is related to Agent.

Feedback (status=done):
The SPARQL query correctly retrieves suppliers located in Toulouse by filtering the address locality with a case-insensitive match for 'toulouse'. The query returns the expected supplier identifier, and the answer matches the query result. The query uses appropriate classes and properties and returns the actual identifier of the supplier as required. No further refinement is needed.

[User] Show me all BOMs which have at least on part from a polish supplier.

[Assistant]
To answer this question, I need to identify the following entities and properties in the knowledge graph:
1. BOMs (Bill of Materials) - entities representing BOMs.
2. Parts - entities representing parts that are included in BOMs.
3. Suppliers - entities representing suppliers of parts.
4. The relationship between BOMs and parts.
5. The relationship between parts and suppliers.
6. The property or attribute indicating the country of the supplier, specifically Poland.

Step 1: Search for entities related to BOMs to understand how BOMs are represented.
Step 2: Search for properties related to BOMs to find how parts are linked to BOMs.
Step 3: Search for properties related to parts to find how suppliers are linked to parts.
Step 4: Search for properties related to suppliers to find how the country or location is represented.
Step 5: Construct a SPARQL query to find BOMs that have at least one part from a Polish supplier.

I will start by searching for entities related to BOM.

[Tool]
Top 10 entity alternatives:
1. BOM Part (pv:BomPart): A (number of) part(s) in a BOM.
2. bom 4 (prodi:bom-4): is a Bill of Material (BOM)
3. bom 19 (prodi:bom-19): is a Bill of Material (BOM)
4. bom 12 (prodi:bom-12): is a Bill of Material (BOM)
5. bom 2 (prodi:bom-2): is a Bill of Material (BOM)
6. bom 11 (prodi:bom-11): is a Bill of Material (BOM)
7. bom 18 (prodi:bom-18): is a Bill of Material (BOM)
8. bom 6 (prodi:bom-6): is a Bill of Material (BOM)
9. bom 15 (prodi:bom-15): is a Bill of Material (BOM)
10. bom 5 (prodi:bom-5): is a Bill of Material (BOM)

[Assistant]
I found several entities representing BOMs, for example, prodi:bom-4, prodi:bom-19, etc. There is also a class or type called pv:BomPart which represents parts in a BOM.

Next, I will search for properties related to BOMs to find how parts are linked to BOMs. I will check properties of one of the BOM entities, e.g., prodi:bom-4.

[Tool]
Top 10 property alternatives:
1. has BOM Part (pv:hasBomPart): has domain Bill of Material (BOM), A part(s) used in this BOM., has range BOM Part
2. type (rdf:type)
3. label (rdfs:label)
4. name (pv:name): The name of something.

No other items found

[Assistant] The property pv:hasBomPart links a BOM to its parts (BOM Part). Now I will check properties of a BOM Part to find how suppliers are linked to parts. I will check properties of the class pv:BomPart.

[Tool]
Top 10 property alternatives:
1. label (rdfs:label)
2. type (rdf:type)
3. comment (rdfs:comment)
4. is Defined By (rdfs:isDefinedBy)

No other items found

[Assistant] No direct property linking BOM Part to supplier found. I will try searching for properties related to supplier in general to see how suppliers are represented and linked.

[Tool]
Top 10 entity alternatives:
1. Supplier (pv:Supplier): The Supplier of some item(s).
2. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier

[Assistant] I found an entity pv:Supplier representing suppliers and a property pv:hasSupplier linking a product to a supplier. I will check if BOM Part or related entities have this property. I will check properties of BOM Part for "supplier" again to see if pv:hasSupplier is used.

[Tool]
Top 10 property alternatives:
1. comment (rdfs:comment)
2. type (rdf:type)
3. label (rdfs:label)
4. is Defined By (rdfs:isDefinedBy)
5. depiction (foaf:depiction)

No other items found

[Assistant] No direct property pv:hasSupplier for BOM Part. I will check properties of a more general product entity to see if BOM Part is a subclass of product or linked to product. I will check if BOM Part is a subclass of something.

[Tool] Got no rows and 3 columns

[Assistant] No subclass relation found for BOM Part. I will try to find properties of BOM Part that link to other entities to explore further. I will list properties used with BOM Part as subject.

[Assistant] No direct property for location found for Supplier. I will try searching for properties related to supplier in general to see if there is any property linking parts or products to suppliers. I will search for properties with the keyword "supplier".

[Tool]
Top 10 property alternatives:
1. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier
2. compatible product (pv:compatibleProduct): A compatible product., has domain Product, has range Product
3. contributor (dct:contributor)
4. publisher (dct:publisher)
5. quantity (pv:quantity): The quantity needed., has domain BOM Part
6. part (pv:hasPart): has domain BOM Part, The Product needed., has range Product
7. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
8. label (rdfs:label)
9. has product manager (pv:hasProductManager): The employee acting as the product manager of the product., has range Employee, has domain Product
10. member of (pv:memberOf): The department to which an agents belongs., has range Department, has domain Agent

[Assistant]
I found the property pv:hasSupplier which links a product to a supplier. Also, the property pv:hasPart links a BOM Part to a Product. The property pv:country links a Supplier to a Country.

This suggests the following chain:
BOM --pv:hasBomPart--> BOM Part --pv:hasPart--> Product --pv:hasSupplier--> Supplier --pv:country--> Country

Next, I will search for the entity representing Poland in the knowledge graph.

[Tool]
Top 10 entity alternatives:
1. Poland (dbpedia:Poland)

[Assistant]
The entity dbpedia:Poland represents Poland in the knowledge graph.

Now I will construct a SPARQL query to find all BOMs that have at least one part from a Polish supplier using the identified properties and entities.

The query returns for each Employee their name, email, phone number, the department they belong to with the department name, and their direct reports with names if available.

I want to update my contact list, for each Employee give me name, email, phone number and the department they belong to as well as their direct report.

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:

You can use the following SPARQL prefixes implicitly in all functions:

wikibase: <http://wikiba.se/ontology#
qb: <http://purl.org/linked-data/cube#

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] I want to update my contact list, for each Employee give me name, email, phone number and the department they belong to as well as their direct report.

[Assistant]
To answer your question, I need to identify the entities and properties related to Employees, their names, emails, phone numbers, departments, and direct reports in the knowledge graph.

Step 1: Search for an example Employee entity to understand its structure and properties. I will search for entities with the keyword "Employee."

[Tool]
Top 10 entity alternatives:
1. Employee (pv:Employee): An employee in my company., is subclass of Agent
2. employee line svg?color=#D6AF00&format=svg (<https://api.iconify.design/clarity/employee-line.svg?color=%23D6AF00&format=svg>)

[Assistant] I found an entity "Employee" (pv:Employee) which represents an employee in the company. Next, I will search for properties related to the Employee entity to find relevant properties for name, email, phone number, department, and direct report.

[Tool]
Top 10 property alternatives:
1. label (rdfs:label)
2. type (rdf:type)
3. comment (rdfs:comment)
4. is Defined By (rdfs:isDefinedBy)
5. depiction (foaf:depiction)
6. sub Class Of (rdfs:subClassOf)

No other items found

[Assistant] The Employee entity does not have a specific property for "name," but it likely uses the standard rdfs:label for the name. Next, I will search for properties related to "email" for the Employee entity.

[Tool]
Top 10 property alternatives:
1. comment (rdfs:comment)
2. label (rdfs:label)
3. type (rdf:type)

No other items found

[Assistant] There is no specific property for email directly linked to the Employee entity. I will try a more general property search for "email" to see if there is a common property used for email addresses.

[Tool]
Top 10 property alternatives:
1. email (pv:email): The e-mail of an agent., has domain Agent
2. address text (pv:addressText): The address text., has domain Agent
3. address country (pv:addressCountry): The address country., has domain Agent
4. comment (rdfs:comment)
5. phone number (pv:phone): has domain Agent, A phone number.
6. name (foaf:name):

7. name (pv:name): The name of something.
8. license (<http://creativecommons.org/ns#license>)
9. label (rdfs:label)
10. ID (pv:id): The ID of a thing.

[Assistant] I found the property pv:email for the email of an agent, and pv:phone for phone number. Also, pv:name and foaf:name are possible name properties. Next, I will check if the Employee entity is a subclass of Agent to confirm these properties apply.

[Tool]
Got 1 row and 3 columns:
| subject                | property                       | object           |
| ---------------------- | ------------------------------ | ---------------- |
| Employee (pv:Employee) | sub Class Of (rdfs:subClassOf) | Agent (pv:Agent) |

[Assistant] The Employee entity is a subclass of Agent, so the properties pv:email, pv:phone, and pv:name should apply to Employee. Next, I will search for the property related to the department an employee belongs to. I will search for properties related to "department."

[Tool]
Top 10 property alternatives:
1. area of expertise (pv:areaOfExpertise): The product category agent is expert for., has range Product Category, has domain Agent
2. label (rdfs:label)
3. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
4. part (pv:hasPart): has domain BOM Part, The Product needed., has range Product
5. has manager (pv:hasManager): The manager of the employee., has domain Employee, has range Manager
6. responsible for (pv:responsibleFor): The product for which a department is responsible., has domain Department, has range Product
7. sub Class Of (rdfs:subClassOf)
8. quantity (pv:quantity): The quantity needed., has domain BOM Part
9. member of (pv:memberOf): The department to which an agents belongs., has range Department, has domain Agent
10. type (rdf:type)

[Assistant] I found the property pv:memberOf which indicates the department to which an agent belongs. This property has domain Agent and range Department, so it should apply to Employee as well. Next, I will search for the property related to the direct report of an employee. I will search for properties related to "direct report."

[Tool]
Top 10 property alternatives:
1. comment (rdfs:comment)
2. responsible for (pv:responsibleFor): The product for which a department is responsible., has domain Department, has range Product
3. ID (pv:id): The ID of a thing.
4. contributor (dct:contributor)
5. quantity (pv:quantity): The quantity needed., has domain BOM Part
6. name (foaf:name):

7. name (pv:name): The name of something.
8. has manager (pv:hasManager): The manager of the employee., has domain Employee, has range Manager
9. address text (pv:addressText): The address text., has domain Agent
10. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier

[Assistant] I did not find a direct property for "direct report," but I found pv:hasManager which indicates the manager of the employee. The direct report relationship is typically the inverse of the manager relationship. I will check if there are employees who have a manager to confirm this. I will query for some employees with their managers.

[Tool]
Got 5 rows and 2 columns:

[Assistant] I found employees with their managers using the property pv:hasManager. To get the direct reports of an employee, I can find employees who have that employee as their manager. Now I will construct the final query to get for each Employee: name, email, phone number, department, and their direct reports.

Yes, there are services that apply to BOM parts where the parts are sourced from Russia. Examples include:
- Service 'D215-3449390 - Manual Inspection' applies to BOM part 'Q694-8417409'.
- Service 'N558-1730215 - Sensor Adjustment' applies to BOM parts 'H642-6966395', 'Z272-2955088', and 'Z518-1747933'.
- Service 'O662-4012383 - Involuntary Service' applies to BOM parts 'H642-6966395', 'Q523-3322183', and 'Z452-1805723'.
- Service 'P516-8211068 - IoT Data Marketing' applies to BOM parts 'Z272-2955088', 'Z518-1747933', and 'Z452-1805723'.
Therefore, we do have services that apply to BOMs with parts sourced from Russia.

Do we have any service that does apply to a BOM where parts are sourced from Russia?

You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Do we have any service that does apply to a BOM where parts are sourced from Russia?

[Assistant]
To answer this question, I need to clarify the key elements:
- "service" that "does apply to a BOM"
- "parts sourced from Russia"

Step 1: Identify entities related to "service" and "BOM" (Bill of Materials).
Step 2: Identify properties or relations that link services to BOMs.
Step 3: Identify parts sourced from Russia.
Step 4: Check if any service applies to BOMs that include parts sourced from Russia.

I will start by searching for entities related to "service" in the knowledge graph.

[Tool]
Top 10 entity alternatives:
1. Service (pv:Service): Some value added service realized based on other product(s)., is subclass of Product
2. account service outline svg?color=#D6AF00&format=svg (<https://api.iconify.design/mdi/account-service-outline.svg?color=%23D6AF00&format=svg>)

[Assistant]
I found an entity "Service" (pv:Service) which is described as some value added service realized based on other product(s) and is a subclass of Product. This seems relevant to the "service" mentioned in the question.

Next, I will search for entities related to "BOM" or "Bill of Materials" to understand how BOMs are represented in the knowledge graph.

[Tool]
Top 10 entity alternatives:
1. BOM Part (pv:BomPart): A (number of) part(s) in a BOM.
2. bom 4 (prodi:bom-4): is a Bill of Material (BOM)
3. bom 19 (prodi:bom-19): is a Bill of Material (BOM)
4. bom 12 (prodi:bom-12): is a Bill of Material (BOM)
5. bom 2 (prodi:bom-2): is a Bill of Material (BOM)
6. bom 11 (prodi:bom-11): is a Bill of Material (BOM)
7. bom 18 (prodi:bom-18): is a Bill of Material (BOM)
8. bom 6 (prodi:bom-6): is a Bill of Material (BOM)
9. bom 15 (prodi:bom-15): is a Bill of Material (BOM)
10. bom 5 (prodi:bom-5): is a Bill of Material (BOM)

[Assistant]
I found entities representing BOMs (Bill of Materials) such as prodi:bom-4, prodi:bom-19, etc. Also, there is a class pv:BomPart which represents parts in a BOM.

Next, I will search for properties that link services to BOMs or BOM parts to understand how services might apply to BOMs.

[Tool]
Top 10 property alternatives:
1. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier
2. responsible for (pv:responsibleFor): The product for which a department is responsible., has domain Department, has range Product
3. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
4. phone number (pv:phone): has domain Agent, A phone number.
5. part (pv:hasPart): has domain BOM Part, The Product needed., has range Product
6. member of (pv:memberOf): The department to which an agents belongs., has range Department, has domain Agent
7. name (foaf:name):

8. name (pv:name): The name of something.
9. license (<http://creativecommons.org/ns#license>)
10. price (pv:price): The price specification of a product., has domain Product, has range Price

[Assistant]
From the properties, I see "pv:hasPart" which links a BOM Part to a Product needed. Also, "pv:hasSupplier" links a product to a supplier, and "pv:country" links a supplier to a country.

I did not find a direct property linking a service to a BOM or BOM part. Since a service is a subclass of Product, it might be linked similarly as a product.

Next, I will check if there are any services (instances of pv:Service) that are linked to BOMs or BOM parts. I will start by listing some instances of pv:Service.

[Assistant]
There are no direct instances of pv:Service listed here, only the class definition.

Next, I will try to find BOM parts that have suppliers from Russia. For that, I will:
- Find BOM parts (pv:BomPart)
- Find their products (pv:hasPart)
- Find suppliers of those products (pv:hasSupplier)
- Find the country of those suppliers (pv:country)
- Filter for country "Russia"

I will first search for the entity representing Russia in the knowledge graph.

I found several BOM parts that have suppliers from Russia. Now, I need to check if there are any services that apply to BOMs containing these parts.

I will try to find if there is any relation between services and BOMs or BOM parts. I will search for properties related to "service" again but this time focusing on BOM or parts.

[Assistant]
I found the property "pv:hasBomPart" which links a BOM to BOM parts. Also, "pv:hasPart" links BOM parts to products.

Since services are a subclass of products, I will check if there are any BOMs that have parts which are services. I will query for BOMs that have BOM parts whose product is a service.

[Tool] Got no rows and 4 columns

[Assistant]
There are no BOMs that have BOM parts whose product is a service.

Next, I will check if there are any services that are linked to BOMs or BOM parts in any other way. I will try to find any triples where the subject or object is a service and the other is a BOM or BOM part.

[Assistant]
The property "pv:eligibleFor" links a Service to a Product and is described as valid product service combinations (bundles, accessories).

I will now check if any of the services (instances of pv:Service) are eligible for any BOMs or BOM parts that have parts sourced from Russia.

I will write a query to find services that are eligible for products which are parts in BOMs with suppliers from Russia.

Which supplier delivers the most reliable Inductor?

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:

You can use the following SPARQL prefixes implicitly in all functions:

qb: <http://purl.org/linked-data/cube#

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Which supplier delivers the most reliable Inductor?

[Assistant]
To answer the question "Which supplier delivers the most reliable Inductor?" I need to identify the following:

1. Entities related to "Inductor" - to find the product or component type.
2. Properties related to suppliers and their reliability or delivery performance.
3. The relationship between suppliers and inductors, including reliability metrics.

Step 1: Search for the entity "Inductor" in the knowledge graph to confirm its existence and get its identifier.

[Tool]
Top 10 entity alternatives:
1. prod cat Inductor (prodi:prod-cat-Inductor): is a Product Category

[Assistant]
The entity "Inductor" exists as a product category with the identifier prodi:prod-cat-Inductor.

Step 2: Search for properties related to suppliers delivering inductors and their reliability. I will first search for properties related to "supplier" and "reliability" to understand how these concepts are represented in the knowledge graph.

[Tool]
Top 10 property alternatives:
1. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier
2. compatible product (pv:compatibleProduct): A compatible product., has domain Product, has range Product
3. contributor (dct:contributor)
4. publisher (dct:publisher)
5. quantity (pv:quantity): The quantity needed., has domain BOM Part
6. part (pv:hasPart): has domain BOM Part, The Product needed., has range Product
7. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country
8. label (rdfs:label)
9. has product manager (pv:hasProductManager): The employee acting as the product manager of the product., has range Employee, has domain Product
10. member of (pv:memberOf): The department to which an agents belongs., has range Department, has domain Agent

[Assistant]
The property "pv:hasSupplier" represents the supplier of a product.

Step 3: Search for properties related to "reliability" to find how reliability is represented.

[Tool]
Top 10 property alternatives:
1. has reliability index (pv:reliabilityIndex): A computed KPI to have an reliablity indicator in the context of a supply chain., has domain Hardware
2. compatible product (pv:compatibleProduct): A compatible product., has domain Product, has range Product
3. supplier (pv:hasSupplier): The supplier of a product., has domain Product, has range Supplier
4. quantity (pv:quantity): The quantity needed., has domain BOM Part
5. is Defined By (rdfs:isDefinedBy)
6. type (rdf:type)
7. name (foaf:name):

8. name (pv:name): The name of something.
9. range (rdfs:range)
10. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country

[Assistant]
The property "pv:reliabilityIndex" is a computed KPI to have a reliability indicator in the context of a supply chain and has domain Hardware.

Step 4: Check if inductors are classified as Hardware or if there is a subclass relationship between product category "Inductor" and Hardware. This will help to confirm if inductors have a reliability index.

| prod cat Inductor (prodi:prod-cat-Inductor) | name (pv:name)     | Inductor                              |

[Assistant]
The entity "Inductor" is a Product Category but not explicitly typed as Hardware. I will check if there are products classified under this category and if those products have a reliability index.

Step 5: Find products that belong to the product category "Inductor" and check if they have a reliability index and a supplier.

[Tool] Got no rows and 3 columns

[Assistant]
No products directly linked to the product category "Inductor" with reliability index and supplier were found.

Step 6: I will try to find products that are of type Hardware and have a reliability index, then check if any of them belong to the product category "Inductor". This might help to find inductors with reliability index.

[Tool] Got no rows and 4 columns

[Assistant]
No products of type Hardware with a reliability index and product category were found.

Step 7: I will try a broader search for products with a reliability index and supplier, regardless of category or type, to see if inductors or related products appear.

[Assistant]
There are products with reliability index and suppliers, but no product category is shown for these results.

Step 8: Check if these products have a product category linked to them. I will check for the first product in the list "prodi:hw-A166-3766336" if it has a product category.

[Tool] Got no rows and 3 columns

[Assistant]
The product "prodi:hw-A166-3766336" does not have a product category linked.

Step 9: I will try to find suppliers who supply inductors by checking if any product has the product category "Inductor" and a supplier. Then I will check the reliability index of those products.

[Tool] Got no rows and 2 columns

[Assistant]
No products with the product category "Inductor" and a supplier were found.

Step 10: I will try to find suppliers who supply products with a reliability index and then check if any of those products are inductors.

[Tool] Got no rows and 3 columns

[Assistant]
No products with both a reliability index and a product category were found.

Step 11: I will try to find suppliers who supply products and check if any of those products are inductors. Then I will check if those products have a reliability index.

[Tool] Got no rows and 2 columns

[Assistant]
No products with the product category "Inductor" and a supplier were found.

Step 12: Since there is no direct link between inductors and suppliers or reliability index, I will try to find suppliers who supply any product and have a reliability index associated with them. Then I will check if any of those products are inductors.

There are suppliers with products that have a reliability index, but the products are not explicitly labeled as inductors.

Step 13: I will check the labels of these products to see if any of them are inductors. I will check the labels of the top 10 products from the previous query.

What is the heaviest coil that does not exceed a base area of 15x15 milimeter?

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] What is the heaviest coil that does not exceed a base area of 15x15 milimeter?

[Assistant]
Step 1: Identify key entities and properties in the question.
- Entity: coil
- Properties: weight (heaviest), base area (not exceeding 15x15 millimeter)

Step 2: Search for entities related to "coil" in the knowledge graph.

[Tool]
Top 10 entity alternatives:
1. prod cat Coil (prodi:prod-cat-Coil): is a Product Category

[Assistant] There is a product category "Coil" (prodi:prod-cat-Coil). Next, I will search for properties related to this product category that might represent weight and base area.

[Tool]
Top 10 property alternatives:
1. type (rdf:type)
2. name (pv:name): The name of something.
3. label (rdfs:label)

No other items found

[Tool]
Top 10 property alternatives:
1. weight (g) (pv:weight_g): The weight of an item measured in grams., has domain Hardware
2. quantity (pv:quantity): The quantity needed., has domain BOM Part
3. amount (pv:amount): has domain Price, The amount.
4. height (mm) (pv:height_mm): The height of an item measured in millimeter., has domain Hardware
5. depth (mm) (pv:depth_mm): The depth of an item measured in millimeter., has domain Hardware
6. currency (pv:currency): has domain Price, The currency.
7. type (rdf:type)
8. name (foaf:name):

9. name (pv:name): The name of something.
10. width (mm) (pv:width_mm): The width of an item measured in millimeter., has domain Hardware

[Assistant] I found a property "weight (g)" (pv:weight_g) which represents the weight of an item in grams. Now I will search for properties related to the base area, which could be represented by width and depth or length.

[Tool]
Top 10 property alternatives:
1. range (rdfs:range)
2. lat (wgs84:lat)
3. address locality (pv:addressLocality): The address locality (city)., has domain Agent
4. height (mm) (pv:height_mm): The height of an item measured in millimeter., has domain Hardware
5. quantity (pv:quantity): The quantity needed., has domain BOM Part
6. depth (mm) (pv:depth_mm): The depth of an item measured in millimeter., has domain Hardware
7. weight (g) (pv:weight_g): The weight of an item measured in grams., has domain Hardware
8. width (mm) (pv:width_mm): The width of an item measured in millimeter., has domain Hardware
9. amount (pv:amount): has domain Price, The amount.
10. country (pv:country): The country where the supplier is located., has domain Supplier, has range Country

[Assistant] The base area can be derived from width (pv:width_mm) and depth (pv:depth_mm) properties, both measured in millimeters. I will now construct a query to find coils with width and depth not exceeding 15 mm and return the heaviest one.

[Tool] Got no rows and 4 columns

[Assistant] No coils were found with width and depth both not exceeding 15 mm. I will try to find coils with width and depth less than or equal to 15 without restricting to the product category to see if there are any such items.

Feedback (status=done):
The SPARQL query correctly retrieves coils with width and depth not exceeding 15 millimeters, orders them by weight in descending order, and limits the result to the heaviest coil. The answer provides the coil IRI along with its weight, width, and depth, matching the query result. The query and answer are accurate and complete for the user's question.
