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] What are the details of nuclear weapons tests, excluding those that are part of a nuclear test series? For each test, include the date (if available), operator (if available), explosive energy equivalent (if available), and their energy equivalent in kilotons (if available).

[Assistant]
To answer this question, I need to identify nuclear weapons tests that are not part of a nuclear test series. Then, for each such test, I will retrieve the date, operator, explosive energy equivalent, and energy equivalent in kilotons if available.

Step 1: Identify the entity for "nuclear weapons test."
Step 2: Identify the property that links a nuclear weapons test to a nuclear test series.
Step 3: Query for nuclear weapons tests that do not have a link to a nuclear test series.
Step 4: Retrieve the date, operator, explosive energy equivalent, and energy equivalent in kilotons for each test.

I will start by searching for the entity "nuclear weapons test."

[Assistant]
The property "explosive energy equivalent" (wdt:P2145) is used for the amount of energy discharged during an explosion. I will use this property for the explosive energy equivalent of the nuclear weapons test.

Next, I will check if there is a separate property for energy equivalent in kilotons or if it is usually represented as a quantity with a unit. I will look for the datatype or unit of the property wdt:P2145 for some nuclear weapons tests. I will first find some nuclear weapons tests that are not part of a series and have this property.

[Assistant] The property "explosive energy equivalent" (wdt:P2145) is represented as a decimal number, which likely corresponds to the energy equivalent in kilotons. Now I will write the final query to get nuclear weapons tests (wd:Q210112) that are not part of any series (do not have wdt:P179), and retrieve their date (wdt:P585), operator (wdt:P137), explosive energy equivalent (wdt:P2145), and the energy equivalent in kilotons (same as wdt:P2145). I will also include optional labels for better readability.

The query returns items that are part of the Camino de Santiago (Way of Saint James), including their coordinates and the routes they are part of. The routes are not necessarily restricted to instances of pilgrims' way, as such explicit relations were not found in the data. The results include items like porte Saint-Jacques, Notre-Dame, Alexanderstraße, and routes like Way of Saint James and Ways of Saint James in France.

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 items are part of the Camino de Santiago (also known as the Way of Saint James), including their coordinates, and the routes they are part of (where those routes are instances of a pilgrims' way)?

[Assistant]
To answer this question, I need to identify the entity for "Camino de Santiago" or "Way of Saint James" in Wikidata. Then, I will find the items that are part of this entity. Additionally, I will retrieve the coordinates of these items and the routes they are part of, where those routes are instances of a pilgrims' way.

Step 1: Search for the entity "Camino de Santiago" or "Way of Saint James" in Wikidata.

[Assistant]
The entity "Way of Saint James" (wd:Q41150) corresponds to the Camino de Santiago pilgrimage. I will now find the items that are part of this Way of Saint James (Camino de Santiago). I will also retrieve their coordinates and the routes they are part of, where those routes are instances of a pilgrims' way.

Step 2: Query for items that are part of the Way of Saint James (wd:Q41150), their coordinates, and the routes they belong to, where those routes are instances of a pilgrims' way.

SPARQL execution failed:
Error while executing a SERVICE request to <http://wikiba.se:80/ontology#label>: SERVICE responded with HTTP status code: 301, Moved Permanently. First 100 bytes of the response: '<html>
<head><title>301 Moved Permanently</title></head>
<body>
<center><h1>301 Moved Permanently'

[Assistant]
The query failed because the SERVICE wikibase:label is not supported by the used QLever SPARQL endpoint. I will rewrite the query without using SERVICE wikibase:label and instead use optional rdfs:label to get labels.

I will also adjust the query to find items that are part of the Way of Saint James (wd:Q41150) using the property "part of" (P361). Then, I will get their coordinates (P625) and find the routes they are part of, where those routes are instances of a pilgrims' way (Q169872). I will get the labels of items and routes using rdfs:label with a filter for English language.

I will limit the results to 100 for performance.

[Assistant]
I retrieved 36 items that are part of the Way of Saint James (Camino de Santiago). Some have coordinates and some have labels. However, the routes they are part of (instances of pilgrims' way) are mostly missing in the results. I will refine the query to explicitly find routes that the items are part of using the property "part of" (P361) instead of "instance of" (P31) for the routes. This might better capture the relationship of items being part of routes.

I will also ensure to get labels for items and routes using rdfs:label with English language filter.

[Assistant]
I retrieved the same 36 items that are part of the Way of Saint James (Camino de Santiago) with their coordinates and labels where available. However, the routes they are part of (instances of pilgrims' way) are still mostly missing in the results. It seems that the items may not have a direct "part of" relationship to the routes that are instances of pilgrims' way in the data.

I will now try to find routes that are instances of pilgrims' way (Q169872) and are part of the Way of Saint James (wd:Q41150). Then, I will find the items that are part of those routes. This might give a better hierarchical structure of the routes and their items.

Step 3: Query for routes that are instances of pilgrims' way and part of the Way of Saint James, and the items that are part of those routes, including coordinates and labels.

There are no routes that are instances of pilgrims' way (Q169872) and are part of the Way of Saint James (wd:Q41150) in the data. This means the hierarchical structure I tried to query does not exist explicitly in the data.

I will try a different approach: I will find routes that are instances of pilgrims' way and have the Way of Saint James as a broader route or related route. Then, I will find items that are part of those routes, including their coordinates and labels.

Step 4: Query for routes that are instances of pilgrims' way and have a relation to the Way of Saint James, and the items that are part of those routes, including coordinates and labels.

There are no routes that are instances of pilgrims' way and have a part of or subclass relation to the Way of Saint James (wd:Q41150) in the data. It seems the data does not explicitly link the Way of Saint James with its routes in this manner.

I will now simplify the query to just find items that are part of the Way of Saint James (wd:Q41150), their coordinates, and the routes they are part of, without restricting the routes to be instances of pilgrims' way. I will also get labels for all entities.

Step 5: Query for items part of the Way of Saint James, their coordinates, and the routes they are part of, with labels.

[Tool] Stopped generation process


There are no Norwegian ships with recorded service entry dates between 1939 and 1946 in the Wikidata knowledge graph. The properties for country of registry (wdt:P8047) and country of origin (wdt:P495) were used to filter Norwegian ships, and the property for service entry date (wdt:P729) was used to filter by the date range. However, no results were found for ships meeting these criteria. This suggests that the data for Norwegian ships entering operational service in that period is not available or not recorded in Wikidata.

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 Norwegian ships entered operational service between 1939 and 1946, along with their service entry dates?

[Assistant]
To answer this question, I need to identify Norwegian ships that entered operational service between 1939 and 1946 and retrieve their service entry dates.

Step 1: Identify the entity type for "ships" and the property for "country of origin" or "flag" to filter Norwegian ships.
Step 2: Identify the property that indicates the date a ship entered operational service.
Step 3: Query for ships with Norwegian origin/flag and filter by the operational service entry date between 1939 and 1946.
Step 4: Retrieve the ships and their service entry dates.

I will start by searching for the property related to the date a ship entered operational service.

[Assistant]
The property "country of registry" (wdt:P8047) is the most relevant to indicate the flag state or country where a ship is registered.

Now I will construct a SPARQL query to find ships with country of registry Norway (wd:Q20) and service entry date between 1939 and 1946. I will retrieve the ships and their service entry dates.

[Tool] Got no rows and 3 columns

[Assistant]
The query returned no results, which might mean that the property for service entry date or the country of registry for ships is not consistently used or the data is incomplete.

I will try a broader approach by searching for ships with Norway as country of origin (wdt:P495) instead of country of registry and check if the service entry date property is used differently or if there is another property for the date a ship entered service.

[Tool] Got no rows and 3 columns

[Assistant]
There are still no results when using country of origin (wdt:P495) for Norway.

I will try to find ships that have any date property related to service entry or commissioning and check if the property wdt:P729 is used for ships in general. I will look for some ships with service entry dates to verify the property usage.

[Assistant]
The property wdt:P729 (service entry) is used for ships to indicate the date they entered operational service.

Since the previous queries with country of registry and country of origin for Norway returned no results, I will try to find ships with Norway as country of registry (wdt:P8047) without filtering by date to check if there are any Norwegian ships with service entry dates recorded. This will help verify if the data exists for Norwegian ships.

[Assistant]
There are Norwegian ships with service entry dates recorded, but none in the range 1939 to 1946 in the sample retrieved.

I will now run a query specifically filtering for Norwegian ships with service entry dates between 1939 and 1946 to confirm if any exist in that range.

[Assistant]
There are no Norwegian ships with recorded service entry dates between 1939 and 1946 in the data.

I will now try to expand the search to ships with Norway as country of origin (wdt:P495) and service entry dates between 1939 and 1946, to check if any ships are recorded with Norway as origin in that period.

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 poems are in the public domain, either in English or with no specified language, and do not have an audio recording?

[Assistant]
To answer this question, I need to identify poems that meet the following criteria:
1. The work is a poem.
2. The work is in the public domain.
3. The language of the work is either English or unspecified.
4. The work does not have an audio recording.

Step 1: Identify the entity for "poem" and the property for "instance of" to filter works that are poems.
Step 2: Identify the property that indicates public domain status.
Step 3: Identify the property for language of the work.
Step 4: Identify the property that links a work to an audio recording.
Step 5: Construct a SPARQL query to find poems that are public domain, in English or no specified language, and do not have an audio recording.

I will start by searching for the entity "poem" in Wikidata.

The property "recording or performance of" (wdt:P2550) can be used to link an audio recording to the work it is a recording of.

Now I will construct a SPARQL query to find poems (wd:Q5185279) that are in the public domain (copyright status wd:P6216 with value indicating public domain), have language either English (wd:Q1860) or no specified language, and do not have an audio recording (no item linked by wdt:P2550).

I will first check the values for copyright status that indicate public domain. I will search for entities related to "public domain" to find the appropriate value for copyright status.
