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. Use the functions to search for 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. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
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 assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. 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.
4. 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.
5. 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.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. 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 countries have more than ten caves?

[Assistant]
Let's break down the question:

1. We need to identify the entity for "cave" in Wikidata.
2. We need to find the property that links caves to countries (likely "country" or "located in the country").
3. We need to count the number of caves per country and filter for those with more than ten.

First, I'll search for the entity "cave" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. cave, also known as cavern (wd:Q35509): natural void under the Earth's surface
2. Cave (wd:Q177726): comune in Italy
3. Carlsbad Caverns National Park, also known as CAVE (wd:Q273195): United States National Park in the Guadalupe Mountains in southeastern New Mexico
4. Cave (wd:Q736010): single by Muse
5. The Cave, also known as Cave (wd:Q1027834): 2005 film directed by Bruce Hunt
6. Cave, also known as Cave, MO (wd:Q957976): village in Missouri
7. CAVE, also known as Cave Co., Ltd., Cave Interactive Co., Ltd. (wd:Q2495040): video game company
8. Cave (wd:Q18436524): human settlement in Italy
9. Cave, also known as Cave, New Zealand (wd:Q5054876): locality in Timaru District, Canterbury Region, New Zealand
10. Cave (wd:Q18506124)

[Assistant]
The relevant entity for "cave" as a natural feature is wd:Q35509.

Next, I need to find the property that links a cave to a country. This is likely "country" or "located in the country". I'll search for properties related to "country" for the entity "cave".

[Tool]
Top 10 property alternatives:
1. OpenStreetMap tag or key, also known as tag, OSM wiki tag or key, OpenStreetMap relation role, OSM tag or key, OSM tag (wd:P1282 as p): OpenStreetMap tagging schema (a Key:key, Tag:key=value, Relation:type, or Role:role) for classes, properties, and values

8. has list, also known as list, topic's list, topic list, related list, list for this topic (wd:P2354 as wdt/p): Wikimedia list related to this subject
9. subclass of, also known as rdfs:subClassOf, sort of, subcategory of, subgenre of, subtype of (wd:P279 as wdt/p): this item is a subclass (subset) of that item; ALL instances of ...stance of volcanic landform); Everest is an instance of mountain
10. Freebase ID, also known as Freebase, MID, Freebase identifier, FID (wd:P646 as wdt/p): identifier for a page in the Freebase database. Format: "/m/0" f...r IDs starting with "/g/", use Google Knowledge Graph ID (P2671)

No other items found

[Assistant] The search did not return a direct "country" property for "cave". However, in Wikidata, the property "country" is commonly wdt:P17. To confirm, I'll search for the property "country" in Wikidata to get its property ID.

[Tool]
Top 10 property alternatives:
1. valid in place, also known as applies to country, applies to location, applies to place, country, true in (wd:P3005 as psv/pr/wdtn/prn/pq/wdt/prv/psn/p/ps/pqn/pqv): place where a statement is valid, applies to part

[Assistant]
The property "country" is wdt:P17, which is used for the sovereign state that an item is in. This is appropriate for linking caves to countries.

Now, I need to find all entities that are instances of "cave" (wd:Q35509), get their country (wdt:P17), group by country, and filter for those with more than ten caves.

I'll construct a SPARQL query to do this.

[Tool]

Feedback (status=refine):
The SPARQL query is almost correct and returns the correct countries with more than ten caves. However, it only returns the country IRIs and the cave count, but does not provide human-readable country names. While labels are optional, including them in an OPTIONAL clause would improve usability. Additionally, the answer should clarify that the list is based on Wikidata's current data, which may be incomplete. The query otherwise follows all rules and does not use unsupported features.

[Assistant]
Thank you for the feedback. To improve usability, I will add an OPTIONAL clause to retrieve the human-readable labels for the countries using rdfs:label. I will also clarify in the answer that the list is based on Wikidata's current data, which may be incomplete.

Here is the refined SPARQL query and answer.

Feedback (status=done):
The SPARQL query correctly identifies countries with more than ten caves by counting cave instances (wd:Q35509) per country (wdt:P17), grouping by country, and filtering with HAVING (COUNT(?cave) > 10). It returns the required IRIs and optionally includes English labels. The answer and query are complete and follow all guidelines.

[User] Give me all cities in New Jersey with more than 100000 inhabitants.

[Assistant]
Let's break down the question:

1. We need to find all cities located in New Jersey.
2. These cities must have a population greater than 100,000.

First, let's identify:
- The entity for "New Jersey".
- The property for "located in the administrative territorial entity".
- The property for "population".
- The class for "city".

Let's start by searching for the entity "New Jersey".

The class for "city" is wd:Q515.

Now, I have all the necessary components:
- Cities: wd:Q515 (instance of or subclass of)
- Located in New Jersey: wdt:P131 wd:Q1408
- Population: wdt:P1082 > 100000

Next, I need to check if cities in New Jersey are directly instances of "city" (wd:Q515) or if they are subclasses or have another property. I'll start by checking if there are any entities that are instances of "city" and located in New Jersey.

[Tool] Got no rows and 1 columns

[Assistant]
It appears that there are no entities that are directly instances of "city" (wd:Q515) and located in New Jersey. This could be because cities in New Jersey might be classified as "city of the United States" or another subclass, or perhaps use a different property for administrative location.

Let's check for subclasses of "city" that might be used for US cities. I'll search for subclasses of "city".

[Assistant]
The entity "city in the United States" is wd:Q1093829. This is likely the class used for cities in New Jersey.

Let's try a query for entities that are instances of "city in the United States" (wd:Q1093829) and located in New Jersey (wd:Q1408).

[Tool] Got no rows and 1 columns

[Assistant]
There are still no results. It's possible that the "located in the administrative territorial entity" (wdt:P131) property is not used directly for cities in New Jersey, or that cities are linked to counties, which are then linked to New Jersey.

Let's try a broader approach: search for entities that are instances of "city in the United States" (wd:Q1093829) and have a population over 100,000, regardless of location, and see if any are in New Jersey by their labels.

Feedback (status=refine):
The SPARQL query is missing a constraint to ensure that the cities are located in New Jersey. Currently, it only selects entities that are instances of 'city in New Jersey' (wd:Q2974552), but this class may not be comprehensive or may not be used consistently in Wikidata. It would be more robust to select entities that are instances of 'city' (wd:Q515) and are located in the administrative territory of New Jersey (wd:Q1408) using the 'located in the administrative territorial entity' (wd:P131) property. Additionally, the query should return the IRIs of the cities, and optionally their labels, but labels should be in OPTIONAL clauses. Please refine the query to address these points.

[Assistant]
Thank you for the feedback. You are correct: relying solely on the class "city in New Jersey" (wd:Q2974552) may miss some cities, as Wikidata's use of classes can be inconsistent. A more robust approach is to select all entities that are instances of "city" (wd:Q515) and are located in New Jersey (wd:Q1408) via the "located in the administrative territorial entity" (wd:P131) property, and to filter by population.

However, as seen earlier, some cities may be linked to counties (e.g., Essex County, Hudson County), which are themselves located in New Jersey. To be comprehensive, we should include cities that are either directly located in New Jersey or located in a county that is located in New Jersey.

Here's my plan:
1. Select all entities that are instances of "city" (wd:Q515).
2. These entities should be either:
   - Directly located in New Jersey (wd:Q1408), or
   - Located in a county that is located in New Jersey.
3. Filter for population greater than 100,000.
4. Return the city IRIs, and optionally their labels.

Let's write this refined SPARQL query.

[Tool] Got no rows and 3 columns

[Assistant]
It appears that there are no results when requiring that the city is an instance of "city" (wd:Q515) and is located in New Jersey (directly or via a county). This suggests that in Wikidata, many New Jersey cities may not be directly typed as "city" (wd:Q515), but rather as "city in New Jersey" (wd:Q2974552) or similar subclasses.

To be more inclusive, I will adjust the query to include entities that are instances of any subclass of "city" (wd:Q515), not just direct instances. This will cover "city in New Jersey" and other possible subclasses.

Let's try again with this approach.

The SPARQL query correctly retrieves all cities in New Jersey with more than 100,000 inhabitants, returning their IRIs and optionally their English labels. The answer matches the query result, and the query adheres to the required guidelines. No further refinement is necessary.

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. Use the functions to search for 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. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
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 assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. 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.
4. 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.
5. 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.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. 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] When did Latvia join the EU?

[Assistant]
Let's break down the question:

1. The user wants to know when Latvia joined the European Union (EU).
2. We need to identify the entity for Latvia and the EU, and the property that links a country to its EU membership date.

Step 1: Search for the entity "Latvia" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. Latvia, also known as Latvija, Republic of Latvia, LVA, lv, Leţmо̄ Vabāmо̄ (wd:Q211): sovereign state in northeastern Europe
2. 1284 Latvia, also known as Latvia (wd:Q137583): asteroid
3. RAF-977, also known as Latvia, RAF-977D (wd:Q2425377): soviet bustype
4. RAF-2203, also known as Latvia (wd:Q1065645): van and minibus manufactured by Rīgas Autobusu Fabrika in Latvia
5. Latvia (wd:Q6497226): constituency of the European Parliament
6. Latvia (wd:Q104537040)
7. Latvia (wd:Q104892776): scientific article published in December 2012
8. Latvia (wd:Q58040021)
9. Latvia (wd:Q103948319): encyclopedia article
10. Latvia (wd:L254271)

[Assistant]
The correct entity for the country Latvia is wd:Q211.

Next, we need to find the property that links a country to its date of joining the European Union. I will search for properties related to "European Union membership" or "EU accession".

[Tool]
Top 10 property alternatives:
1. Encyclopedia of the History of Ukraine ID, also known as EHU, EIY, history.org.ua, ЕІУ (wd:P8935 as wdt/p): ID for an entry on the official website of the Encyclopedia of the History of Ukraine
2. legislative body, also known as aboriginal council, Zila, Tehsil, rural council, representative body (wd:P194 as wdt/p): legislative body governing this entity; political institution wi...ted representatives, such as a parliament/legislature or council
3. subreddit, also known as r/, reddit, Reddit community ID, Reddit forum, Reddit sub ID (wd:P3984 as wdt/p): name of the Reddit forum associated to this subject
4. official website, also known as site (official), home page, site official, URL, URL (official) (wd:P856 as wdt/p): URL of the official page of an item (current or former). Usage: ...but see the "Hijacked or dead websites" section of the Talk page, URL

9. member of, also known as band member of, membership, member of musical group, in musical group, be member of (wd:P463 as wdt/p): organization, club or musical group to which the subject belongs...ical position, such as a member of parliament (use P39 for that), part of
10. basic form of government, also known as form of government, government, type of government (wd:P122 as wdt/p): subject's government

No other items found

[Assistant]
The property "member of" (wd:P463) looks promising, as it could link Latvia to the European Union. We can use this property to see if Latvia is a member of the EU and then look for a qualifier or related property that specifies the date it joined.

Next, I will check how the "member of" property is used for Latvia, and whether there is a qualifier for the date of joining.

[Assistant]
Latvia (wd:Q211) is indeed a member of the European Union (wd:Q458) via the "member of" (wdt:P463) property. Now, we need to find if there is a qualifier on this statement that specifies the date Latvia joined the EU.

I will list the full statement triples (not just the direct property) for Latvia's membership in the European Union to see if there is a date qualifier.

[Assistant]
There are multiple statements for Latvia's "member of" property. We need to find the one where the object is the European Union (wd:Q458), and then check for a qualifier that gives the date of joining.

Let's list the qualifiers for the statement where Latvia is a member of the European Union.

[Tool] Only two of subject, property, or object should be provided.

[Assistant]
I made an error: the list function only allows at most two constraints. Instead, I should list all "member of" statements for Latvia and check which one has the European Union as the object, then look for qualifiers on that statement.

Let me list the full statements for "member of" (p:P463) for Latvia and look for the one with the European Union as the object and see its qualifiers.

[Assistant]
I found the correct statement: Latvia (wd:Q211) is a member of the European Union (wd:Q458) with a qualifier "start time" (pq:P580) of 2004-05-01.

Now, I will construct a SPARQL query that returns the date Latvia joined the EU, using the "member of" property with a qualifier for "start time".

Feedback (status=done):
The SPARQL query is correct and follows all the rules: it returns the actual date (not just a label), uses the correct entities and properties, and does not include any unnecessary computation or unsupported clauses. The answer matches the expected result for when Latvia joined the EU. No further refinement is needed.
