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.

You have access to the following knowledge graphs:

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- 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.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- 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.
- 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.
- 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.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

[Assistant] I'll list triples for the Carolina Panthers (wd:Q330120) with property head coach (wdt:P286 / p:P286) to inspect qualifiers and time ranges.

[Tool]
Got 1 row and 3 columns:

[Assistant] I'll inspect each statement node to find which one applies to around 2013 — likely Ron Rivera was head coach from 2011–2019. I'll query statements with qualifiers start time (P580) and end time (P582) and the value for the head coach. I'll build a query to retrieve head coaches with start and end times for the team.

[Assistant] I'll query the Carolina Panthers head coach (P286) statements and select the coach whose head-coach tenure overlaps the year 2013 (i.e., start <= end of 2013 and end >= start of 2013 or no end date). I'll run a SPARQL SELECT that returns the coach IRI (and optional English label and start/end qualifiers) filtered for overlap with 2013. Now I'll execute that query.

[Tool]
Got 1 row and 4 columns:
| coach                    | coachLabel      | start                               | end                                 |

[Assistant] The query returns Ron Rivera as the head coach during 2013. This answers the user's question. I'll prepare the final ASK or SELECT? The user asked "who will coach carolina panthers in 2013?" It's past tense; they asked who will coach in 2013 — probably expecting a name. Provide a SPARQL query that returns the coach IRI and label; per instructions the query should be executed before giving an answer. I already executed queries. Now I'll finalize with a SPARQL query that returns the coach IRI and label for head coach overlapping 2013 and then call the answer function with that query and the human answer. I'll include the final SPARQL used.

[User] who is nicolas cage married too?

[Assistant]
I will first find the Wikidata item for Nicolas Cage, then look for properties that indicate his spouse(s) (e.g., "spouse" property). I'll verify the property identifier and then construct a SPARQL query that returns the spouse items (with IRIs and optional labels). I'll run the query to get the current spouse(s) recorded in Wikidata.

First I'll search for the Nicolas Cage entity.

| Nicolas Cage (wd:Q42869) | spouse (wdt:P26) | Lisa Marie Presley (wd:Q237324) |

[Assistant] I'll run a SPARQL query that fetches all spouses (wdt:P26) of Nicolas Cage (wd:Q42869), returning the spouses' IRIs and English labels. This verifies and returns the people he has been married to in Wikidata. Now I'll execute that query.

[Assistant] I'll check the spouse statements for Nicolas Cage to see marriage start and end qualifiers, so I can identify which spouse(s) are currently married to him (statements without an end qualifier). I'll run a SPARQL query that returns spouses with optional start (pq:P580) and end (pq:P582) qualifiers.

[Assistant] I'll run a SPARQL query that retrieves Nicolas Cage's spouse statements that have no end date qualifier (pq:P582), which should give the person he's currently married to, including the marriage start date if present. Then I'll provide the final answer based on the query results.

[System]
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.

You have access to the following knowledge graphs:
wikidata at http://localhost:7001 without notes

You are provided with the following notes across all knowledge graphs:

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- 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.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- 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.
- 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.
- 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.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

Answer:
I queried Wikidata for items that are films (instance of / subclass of Q11424) where David Carradine (wd:Q187038) is listed as a cast member (property P161). The SPARQL query above returns the film IRIs, optional English labels, and publication dates. The query returned 271 film items. Examples from the results include: Think Big; Death Race; The Misfit Brigade; Deathsport; Crank: High Voltage; The Serpent's Egg; Nowhere to Run; Richard III; Heaven with a Gun; Young Billy Young; Dinocroc vs. Supergator; Stretch; Eldorado; Night of the Templar; Corman's World: Exploits of a Hollywood Rebel.

You can run the provided SPARQL query against the Wikidata endpoint to retrieve the full list (IRIs, labels, and dates) of movies David Carradine appeared in.

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.

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- 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.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- 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.
- 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.
- 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.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

[User] what movies did david carradine play in?

[Assistant] I will first find the Wikidata entity for "David Carradine" and then look for properties that link him to films (e.g., cast member P161 or filmography-related properties). I'll search for the entity now.

Answer:
Thought process and steps:
1) I found the Wikidata item for Brazil (wd:Q155).
2) I searched for the appropriate property for type of political system: basic form of government (wdt:P122).
3) I queried wd:Q155 wdt:P122 to get the government types and their English labels.

SPARQL query results (IRI and English label):
- wd:Q512187 — federal republic
- wd:Q49892 — presidential system
- wd:Q188759 — representative democracy

Plain-language conclusion:
Brazil is a federal presidential representative democracy — i.e. a federal republic with a presidential system and representative democracy (as shown by the Wikidata values above).

what type of political system is brazil?

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- 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.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- 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.
- 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.
- 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.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

when did the big earthquake hit san francisco?

[System]
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.

You have access to the following knowledge graphs:
wikidata at http://localhost:7001 without notes

You are provided with the following notes across all knowledge graphs:
