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:
freebase at https://qlever.cs.uni-freiburg.de/api/freebase

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

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.

[Assistant] The property "Teams" (fb:sports.pro_athlete.teams) seems to be the most relevant to find the WNBA team of Diana Taurasi. I will now query the teams of Diana Taurasi using this property.

| fb:m.0z3t_lb |          |
| fb:m.0z6bvmq |          |

[Assistant] Diana Taurasi is associated with four teams in the knowledge graph, but their names are not directly shown. I will now query the names of these teams to identify which one is a WNBA team. I will do this by querying the names and types of these teams.

[Tool]
SPARQL execution failed:
Tried to allocate 3.3 GB, but only 3.3 GB were available. Clear the cache or allow more memory for QLever during startup

[Assistant] The query to get the names and types of the teams failed due to memory limitations. I will try a simpler query to get just the names of the teams one by one to avoid memory issues. I will start with the first team fb:m.0kc2_tr.

[Tool] Got no rows and 1 columns

[Assistant] The first team fb:m.0kc2_tr does not have a name property. I will try the second team fb:m.0z3t_gj now.

[Tool] Got no rows and 1 columns

[Assistant] The second team fb:m.0z3t_gj also does not have a name property. I will try the third team fb:m.0z3t_lb now.

[Assistant] The third team fb:m.0z3t_lb also does not have a name property. I will try the fourth team fb:m.0z6bvmq now.

[Tool] Got no rows and 1 columns

[Assistant] None of the four teams associated with Diana Taurasi have a name property in the knowledge graph. I will try to find another property that might indicate the team name or league for these teams. I will check the properties of one of these teams, for example fb:m.0kc2_tr.

[Assistant] The team fb:m.0kc2_tr is a sports team roster entry for Diana Taurasi. The actual team is linked by the property fb:sports.sports_team_roster.team and it is "Phoenix Mercury" (fb:m.0lr76). I will now get the name of this team entity.

Feedback (status=refine):
The answer states that Diana Taurasi is on the Phoenix Mercury, but the SPARQL query result returns a different team identifier (fb:m.0kc2_tr) which does not match the Phoenix Mercury (fb:m.0lr76). The query also seems to have a mismatch in the triple patterns: it uses Diana Taurasi's entity but then filters teams by a different team entity (fb:m.0lr76). The query should be corrected to directly retrieve the teams associated with Diana Taurasi without filtering by a specific team. Additionally, the query should return the team identifier and optionally the label for clarity. Please revise the SPARQL query to correctly retrieve the WNBA team(s) Diana Taurasi is on and ensure the returned team matches the answer given.

[Assistant] Thank you for the feedback. I understand that the SPARQL query should directly retrieve the teams associated with Diana Taurasi without filtering by a specific team entity. The query should return the team identifier and optionally the label for clarity. I will revise the query accordingly to get the teams of Diana Taurasi and their names.

[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:
freebase at https://qlever.cs.uni-freiburg.de/api/freebase

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

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

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.

I have found the entities for the four nations of the United Kingdom:
- England (fb:m.02jx1)
- Scotland (fb:m.06q1r)
- Wales (fb:m.0j5g9)
- Northern Ireland (fb:m.05bcl)

Now I will check if these four entities are related to the United Kingdom (fb:m.07ssc) by any property that indicates they are part of the United Kingdom. I will check the property "part of" or similar for each of these entities.

The four nations of the United Kingdom are represented by the entities:
- England (fb:m.02jx1)
- Scotland (fb:m.06q1r)
- Wales (fb:m.0j5g9)
- Northern Ireland (fb:m.05bcl)

Each of these entities has the property "Contained by" (fb:location.location.containedby) with the object being the United Kingdom (fb:m.07ssc). This confirms that these four nations are part of the United Kingdom.

I will now formulate the final SPARQL query to return these four nations of the United Kingdom.

[Tool] Stopped generation process

[User]
Feedback (status=done):
The SPARQL query correctly retrieves the four nations of the United Kingdom by filtering the entities contained by the United Kingdom and explicitly listing the four known nations: England, Scotland, Wales, and Northern Ireland. The query returns both the identifiers and English labels, which aligns with the requirement to provide actual IRIs and optional human-readable labels. The answer is accurate and complete. No further refinement is necessary.

Here are some famous people from Barbados with their identifiers and names (labels): Hadan Holligan, Kycia Knight, Shaquana Quintyne, Shakera Selman, Kyshona Knight, Odimumba Kwamdela, Hilary Beckles, Colin Young, Hugh Laing, John Holder, and others. The SPARQL query retrieves people whose place of birth is Barbados.

[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:
freebase at https://qlever.cs.uni-freiburg.de/api/freebase

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

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

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 famous people are from barbados?

[Assistant] Let's start by looking at some examples.

[Tool]
Example 1:
Question:
what language did ancient romans write in?

SPARQL:

Using properties:
Cause of death (fb:people.deceased_person.cause_of_death): part of Deceased Person schema, links to type Cause Of Death

[Assistant]
From the examples, I see that to find people from a specific place, we can use the property related to places lived or place of birth. For the question "what famous people are from Barbados?", we want to find people who have Barbados as their place of birth or place lived.

Next, I will search for the entity "Barbados" in the knowledge graph to get its identifier.

[Assistant]
The property "Place of birth" (fb:people.person.place_of_birth) seems to be the appropriate property to find people born in Barbados.

I will now write a SPARQL query to find people whose place of birth is Barbados (fb:m.0162v). I will also try to get their names (rdfs:label) as optional information.
