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 does the vietnam war end?

[Assistant]
To answer the question "When does the Vietnam War end?" I need to find the entity representing the Vietnam War and then find the property that indicates its end date or end year.

Step 1: Search for the entity "Vietnam War" in the Freebase knowledge graph.

[Tool]
Top 10 entity alternatives:
1. Vietnam War, also known as American War, Vietnam Conflict, Second Indochina War (fb:m.07_nf): The Vietnam War, also known as the Second Indochina War, and als... operations, involving ground forces, artillery, and airstrikes., has type Military Conflict

10. War in Vietnam (fb:m.0bwhf7n): The War in Vietnam, codenamed Operation Masterdom by the British... that grew out of the British occupation of Saigon from 1945–46., has type Military Conflict

[Assistant]
The most relevant entity for the Vietnam War is fb:m.07_nf, which is described as the Vietnam War, also known as the Second Indochina War, a military conflict.

Step 2: Now I will search for properties related to the end or end date of this entity (Vietnam War fb:m.07_nf).

[Assistant]
The property "End date" (fb:time.event.end_date) seems to be the correct property to find the end date of the Vietnam War (fb:m.07_nf).

Step 3: I will now construct a SPARQL query to get the end date of the Vietnam War using the identified entity and property.

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]
There are no objects related to Meg Griffin for the property "voice actor" in the knowledge graph.

Step 13: Since the knowledge graph does not provide direct information about the voice actor for Meg Griffin in season 1 of Family Guy, I will provide a SPARQL query that retrieves the first TV appearance of Meg Griffin and the performances in that episode as a proxy to find the voice actor.

Here is the SPARQL query:

[Tool] Stopped generation process

[User]
Feedback (status=refine):
The system correctly identified Meg Griffin's first TV appearance episode and retrieved performances in that episode, which is a good start. However, it did not specifically link the performances to the voice actor of Meg Griffin. The query should be refined to filter performances to those specifically related to Meg Griffin's character and to retrieve the actor or voice actor associated with those performances. Additionally, the query should ensure it focuses on season 1 episodes of Family Guy to answer the question precisely. Including labels for the actors would also improve readability.

[Assistant]
Thank you for the feedback. I will refine the query to specifically link the performances to the character Meg Griffin and retrieve the actor or voice actor associated with those performances. I will also ensure the query focuses on season 1 episodes of Family Guy and include labels for the actors for better readability.

Step 1: I know the first TV appearance of Meg Griffin is the episode "Death Has a Shadow" (fb:m.07h5g6), which is in season 1 of Family Guy.

Step 2: I will query the performances in this episode that are linked to Meg Griffin and retrieve the actors or voice actors associated with those performances, including their labels.

[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:
fb: <http://rdf.freebase.com/ns/
fbkey: <http://rdf.freebase.com/key/
rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#

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 year did houston rockets win their first championship?

[Assistant] The property "Championships" (fb:sports.sports_team.championships) is related to the Houston Rockets entity and links to the type Sports League Championship Event. I will now query the championships of the Houston Rockets and retrieve the years of those championships to find the first one.

[Tool] Got no rows and 2 columns

[Assistant] The query did not return any results for the championships and their years for the Houston Rockets.

[Assistant] The property "Championships" (fb:sports.sports_team.championships) is still the most relevant property related to titles or wins for the Houston Rockets. Since the previous query did not return results, I will try a broader query to list the championships of the Houston Rockets without filtering by year first. Then I will inspect the results to find the year of the first championship.

[Assistant] The Houston Rockets have two championships listed: "1994 NBA Finals" and "1995 NBA Finals." These are likely the years they won the championships. To confirm the exact year of their first championship, I will query the year for the "1994 NBA Finals" championship event.

[Tool] Got no rows and 1 columns

[Assistant] The query to get the year for the "1994 NBA Finals" championship event did not return any results. I will try to get the label or description of the "1994 NBA Finals" event to confirm the year from its name.
