[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. 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.

Step 1: Identify the entity for Eduardo Paolozzi.
Step 2: Search for properties related to materials or mediums used in his work.
Step 3: Query the values of those properties for Eduardo Paolozzi.

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

[Assistant] The property "fabrication method" (wdt:P2079) might be related to the method or medium used in artworks. I will check if Eduardo Paolozzi has any values for this property.

[Tool] Got no rows and 2 columns

[Assistant] Eduardo Paolozzi does not have any values for the property "fabrication method" either. Since there is no direct property or value for materials used by Eduardo Paolozzi or his works in Wikidata, I will provide an answer stating that this information is not available in the knowledge graph.

[Tool] Stopped generation process

Feedback (status=done):
The system correctly identified that there is no direct information in Wikidata about the materials Eduardo Paolozzi used in his work. It appropriately queried for his works and confirmed that these works do not specify the materials used. The SPARQL query is well-formed and returns relevant works by Eduardo Paolozzi, which supports the conclusion. The answer is complete and accurate given the available data.

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]
From the examples, we see that for a sports team, the property "home venue" (wdt:P115) or "headquarters location" (wdt:P159) can be used to find the city or place where the team plays or is based.

Next, I will search for the entity "Fulham" in Wikidata to identify the correct entity for the football club Fulham.

[Assistant] The London Borough of Hammersmith and Fulham is located in Greater London. Therefore, the city where Fulham Football Club plays is London. I will now provide the final answer.

[Tool] Stopped generation process

[User]
Feedback (status=refine):
The answer states that Fulham Football Club plays in the city of London, but the SPARQL query returns 'Greater London' (wd:Q23306), which is a larger administrative area rather than the specific city. The query uses a FILTER to restrict the city to Greater London, which is not the actual city but a region. To improve, the query should be adjusted to find the actual city or town where Fulham's home venue is located, likely 'London' (wd:Q84), without filtering to Greater London. Also, the query should return the actual city entity and its label to correctly answer the question.

[Assistant] Thank you for the feedback. I understand that the query should return the actual city entity and label, specifically "London" (wd:Q84), rather than the larger administrative area "Greater London" (wd:Q23306). I will adjust the query to find the city or town where Fulham's home venue is located without filtering to Greater London and return the city entity and its label.

[Tool] Got no rows and 2 columns

[Assistant] The query did not return any results when looking for an entity that is an instance or subclass of city (wd:Q515) in the administrative territorial entities of the venue. I will try a more direct approach by checking if the venue is located in London (wd:Q84) or if the venue's location is part of London. I will also check for other possible administrative territorial entities without restricting to city instances.

[Assistant] The venue Craven Cottage is located in several administrative entities including London (wd:Q23939248). This confirms that the city where Fulham Football Club plays is London. I will now provide the final answer with this corrected information.

Feedback (status=refine):
The SPARQL query correctly identifies that Fulham Football Club plays in London and returns the city along with its label. However, the query includes a FILTER that restricts the city to London explicitly, which is redundant since the question is to find the city where Fulham plays, not to check if it is London. Removing this filter would make the query more general and correct for similar questions about other clubs. Also, the query uses the property wdt:P131* to find the administrative territorial entity of the venue, which is appropriate. The answer is correct and complete, but the query can be improved by removing the explicit filter for London to better reflect the question's intent.

[Assistant] Thank you for the feedback. I will remove the explicit filter for London in the query to make it more general and suitable for similar questions about other clubs. The query will return all administrative territorial entities (including the city) where Fulham's home venue is located, and I will limit the results to the first city entity found. I will now update the query accordingly.

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 time zone is anaheim california?

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

[Tool]
Example 1:
Question:
what time zone is it in california?

SPARQL:
SELECT DISTINCT ?x WHERE {
  wd:Q99 wdt:P421 ?x .
}

Using entities:
California, also known as US-CA, State of California, The Golden State, Calif., Cali. (wd:Q99): state of the United States of America

Using properties:
located in time zone, also known as TZ, time zone, timezone (wd:P421 as wdt): time zone for this item

Example 2:
Question:
what is my timezone in california?

SPARQL:
SELECT DISTINCT ?x WHERE {
  wd:Q99 wdt:P421 ?x .
}

Using entities:
California, also known as US-CA, State of California, The Golden State, Calif., Cali. (wd:Q99): state of the United States of America

Using properties:
located in time zone, also known as TZ, time zone, timezone (wd:P421 as wdt): time zone for this item

Example 3:
Question:
what is the time zone in california called?

SPARQL:
SELECT DISTINCT ?x WHERE {
  wd:Q99 wdt:P421 ?x .
}

Using entities:
California, also known as US-CA, State of California, The Golden State, Calif., Cali. (wd:Q99): state of the United States of America

Using properties:
located in time zone, also known as TZ, time zone, timezone (wd:P421 as wdt): time zone for this item

[Assistant] From the examples, the property "located in time zone" (wdt:P421) is used to find the time zone of a place. Now, I need to find the entity for Anaheim, California, and then query its time zone using this property. I will first search for the entity "Anaheim California" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. Anaheim, also known as Anaheim, CA, Anaheim, California (wd:Q49247): city in Orange County, California, United States

Feedback (status=retry):
The SPARQL query correctly uses the property for head coach (wdt:P286) to find the coach of the Carolina Panthers (wd:Q330120). However, the answer given is incorrect. Dave Canales is not the coach of the Carolina Panthers; he is the offensive coordinator for the Seattle Seahawks. The current head coach of the Carolina Panthers is Frank Reich (as of 2024). The query itself is fine, but the system's answer is factually wrong. Please verify the data source or update the query to ensure it returns the correct current head coach of the Carolina Panthers. Also, double-check the property usage and the data freshness in Wikidata.

[Assistant]
Thank you for the feedback. I will verify the property usage and check if there is a more specific property or qualifier that indicates the current head coach for the Carolina Panthers. I will also check if there is a statement with a qualifier for the time period or start date to ensure the coach is current.

First, I will check the statements for the Carolina Panthers with the property P286 (head coach) to see if there are qualifiers indicating the time period or start date.

| Carolina Panthers (wd:Q330120) | head coach (wdt:P286) | Dave Canales (wd:Q47456134) |

[Assistant] The direct property wdt:P286 only shows Dave Canales as the head coach, which seems outdated or incorrect. I will now check the statements (not direct) for the Carolina Panthers with property P286 to see if there are qualifiers such as start time or end time that can help identify the current head coach.

[Assistant] This statement says Frank Reich was head coach with start time 2023-01-01 and end time 2023-01-01, which seems contradictory. I will check another statement node for more recent or current head coach info.

[Assistant] This statement says Perry Fewell was head coach with start time 2019-01-01 and end time 2019-01-01, which is also in the past. I will now check for statements without an end time qualifier, which would indicate a current position. I will write a query to find the head coach statements for the Carolina Panthers with no end time qualifier or with the latest start time.

[Assistant]
The query still returns Dave Canales as the current head coach with a start time of 2024-01-01, which contradicts the known fact that Frank Reich is the current head coach. This suggests Wikidata might not be up-to-date or the property usage is not consistent.

I will try a different approach: search for Frank Reich in Wikidata and check if he is linked as head coach of the Carolina Panthers. This might help confirm the correct current coach.

[Assistant] There is no direct property indicating Frank Reich's role as head coach of the Carolina Panthers in his properties. Given the inconsistencies and lack of up-to-date information in Wikidata, I will provide a refined query that retrieves the head coach with the latest start time and no end time qualifier, which is the best we can do with the current data. I will also mention the known correct answer based on external knowledge.

Feedback (status=refine):
The SPARQL query correctly retrieves the current head coach of the Carolina Panthers according to Wikidata, returning Dave Canales with a start time of 2024-01-01. However, the user notes that the actual current head coach as of 2024 is Frank Reich, which suggests Wikidata's data may be outdated or incorrect. The query itself is well-formed and follows best practices, but the data source may not be up to date. It would be good to mention this limitation clearly in the answer and possibly suggest verifying with another source if up-to-date accuracy is critical. No changes to the query are necessary unless a more recent or alternative data source is available.

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] who played kirk?

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

[Tool]
Example 1:
Question:
who played captain kirk in star trek?

SPARQL:
SELECT DISTINCT ?x WHERE {
  ?p p:P161 ?y .
  ?y ps:P161 ?x ; pq:P453 wd:Q16311 .
}

Using entities:
James T. Kirk, also known as James Kirk, James Tiberius Kirk, Jim Kirk, Captain Kirk, Captain James Tiberius Kirk (wd:Q16311): fictional character from Star Trek, spaceship captain, tactician, explorer

Using properties:
cast member, also known as feat., starring (film/play), film starring, starring, actor (wd:P161 as ps/p): actor in the subject production [use "character role" (P453) and...use "recorded participant" (P11108) for non-fiction productions], significant person, performer
character role, also known as role, plays, performer of, as, acting role (wd:P453 as pq): specific role played or filled by subject -- use only as qualifier of "cast member" (P161), "voice actor" (P725)

Example 2:
Question:
where does kirk cameron live now?

SPARQL:
SELECT DISTINCT ?x WHERE {
  wd:Q471858 wdt:P551 ?x .
}

Using entities:
Kirk Cameron (wd:Q471858): television producer, television actor, American actor, film producer, screenwriter, voice actor, comedian, composer, dancer, singer, actor

Using properties:
residence, also known as living in, place of residence, resided at, resided in, resident in (wd:P551 as wdt): the place where the person is or has been, resident, location

Example 3:
Question:
who played kitt in knight rider?

SPARQL:
SELECT DISTINCT ?x WHERE {
  wd:Q464009 p:P725 ?p .
  ?p ps:P725 ?x ; pq:P453 wd:Q1088996 .
}

Using entities:
KITT, also known as K.I.T.T., Knight Industries Two Thousand (wd:Q1088996): fictional car in the 1980s television series Knight Rider
Knight Rider (wd:Q464009): 1982–1986 American television series

Using properties:
character role, also known as role, plays, performer of, as, acting role (wd:P453 as pq): specific role played or filled by subject -- use only as qualifier of "cast member" (P161), "voice actor" (P725)
voice actor, also known as voice actors, voice dubber, voice actress, voice actresses, voiced by (wd:P725 as ps/p): performer of a spoken role in a creative work such as animation,... (P453) as qualifier] [use "cast member" (P161) for live acting], film crew member, cast member

[Assistant]
From the examples, it is clear that the question "who played kirk?" is about the actor who played the character Kirk, specifically Captain Kirk from Star Trek. The relevant properties are "cast member" (P161) with the qualifier "character role" (P453) to specify the character played.

Next, I will search for the entity "Kirk" to identify the specific character, likely Captain Kirk from Star Trek. Then I will use that entity to find the actor who played this character.

9. Duncan Kinloch Kirk, also known as Captain Duncan Kinloch Kirk (wd:Q75243859): Peerage person ID=5744
10. Who Killed Captain Kirk? (wd:Q111739107)

[Assistant] The entity for the fictional character Captain Kirk from Star Trek is wd:Q16311. Now I will construct a SPARQL query to find the actor who played this character using the property "cast member" (P161) with the qualifier "character role" (P453) set to Captain Kirk (wd:Q16311).

Feedback (status=done):
The SPARQL query correctly retrieves all actors who played the character Captain Kirk (wd:Q16311) by using the property 'cast member' (P161) with the qualifier 'character role' (P453). The query returns the actor identifiers and their English labels, which matches the user's question 'who played kirk?'. The answer listing William Shatner, Sam Witwer, Chris Pine, Paul Wesley, and Lloyd Ahlquist is accurate and complete based on the query results. No further refinement is necessary.
