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 is the main language used in china?

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

[Tool]
Example 1:
Question:
what is the official language in china?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.0d05w3 ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.0d05w3 fb:location.country.official_language ?x .
}

Using entities:
China, also known as People's Republic of China (fb:m.0d05w3): China, officially the People's Republic of China, is a sovereign...h-largest by total area, depending on the method of measurement., has type Country

Using properties:
Official Language (fb:location.country.official_language): links to type Human Language, part of Country schema

Example 2:
Question:
what type of language does china speak?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.0d05w3 ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.0d05w3 fb:location.country.official_language ?x .
}

Using entities:
China, also known as People's Republic of China (fb:m.0d05w3): China, officially the People's Republic of China, is a sovereign...h-largest by total area, depending on the method of measurement., has type Country

Using properties:
Official Language (fb:location.country.official_language): links to type Human Language, part of Country schema

Example 3:
Question:
what kind of language do china speak?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.0d05w3 ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.0d05w3 fb:location.country.official_language ?x .
}

Using entities:
China, also known as People's Republic of China (fb:m.0d05w3): China, officially the People's Republic of China, is a sovereign...h-largest by total area, depending on the method of measurement., has type Country

Using properties:
Official Language (fb:location.country.official_language): links to type Human Language, part of Country schema

[Assistant] From the similar examples, it appears that the property "fb:location.country.official_language" is used to find the main or official language of a country. The entity for China is "fb:m.0d05w3". I will now construct a SPARQL query to find the official language of China using this property and entity.

[Tool]
Got 1 row and 1 column:
| language                      |
| ----------------------------- |
| Standard Chinese (fb:m.0653m) |

[Tool] Stopped generation process

[User]
Feedback (status=done):
The SPARQL query correctly retrieves the official language of China using the property fb:location.country.official_language. The result 'Standard Chinese' is accurate as the main language used in China. The query is well-formed and returns the expected identifier for the language. No further refinement is necessary.

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 four nations of the united kingdom?

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

[Tool]
Example 1:
Question:
what are the four nations of the uk?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.07ssc ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.07ssc fb:location.location.contains ?x .
  ?x fb:common.topic.notable_types fb:m.01mp .
}

Using entities:
Country, also known as Empire (fb:m.01mp): The type country in Freebase can and should be used with a varie...s with little population or autonomy will be typed as a country.
United Kingdom, also known as United Kingdom of Great Britain and Northern Ireland, United Kingdom of Great Britain and Ireland, United Kingdom of Great Britain, UK, U.K. (fb:m.07ssc): The United Kingdom of Great Britain and Northern Ireland, common...urth-largest in Europe and second-largest in the European Union., has type Country

Using properties:
Notable types (fb:common.topic.notable_types): part of Topic schema, links to type Type
Contains (fb:location.location.contains): part of Location schema, links to type Location

Example 2:
Question:
what four countries are in the united kingdom?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.07ssc ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.07ssc fb:base.aareas.schema.administrative_area.administrative_children ?x .
  ?x fb:base.aareas.schema.administrative_area.administrative_area_type fb:m.0hzjlmp .
}

Using entities:
United Kingdom, also known as United Kingdom of Great Britain and Northern Ireland, United Kingdom of Great Britain and Ireland, United Kingdom of Great Britain, UK, U.K. (fb:m.07ssc): The United Kingdom of Great Britain and Northern Ireland, common...urth-largest in Europe and second-largest in the European Union., has type Country

Administrative children (fb:base.aareas.schema.administrative_area.administrative_children): part of Administrative Area schema, links to type Administrative Area

Example 3:
Question:
what 4 countries are part of the united kingdom?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.07ssc ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.07ssc fb:location.country.first_level_divisions ?x .

Using properties:
First level divisions (fb:location.country.first_level_divisions): links to type Administrative Division, part of Country schema

[Assistant]
From the similar examples, it appears that the United Kingdom is represented by the entity fb:m.07ssc in Freebase. The four nations of the United Kingdom can be found using properties like:
- fb:base.aareas.schema.administrative_area.administrative_children with the type fb:m.0hzjlmp (UK constituent country)
- fb:location.country.first_level_divisions

I will now try to query the four nations of the United Kingdom using the property fb:base.aareas.schema.administrative_area.administrative_children and filter for the type fb:m.0hzjlmp (UK constituent country).

Feedback (status=done):
The system correctly identified the four nations of the United Kingdom as England, Northern Ireland, Scotland, and Wales. The SPARQL query is well-constructed, using the administrative children of the United Kingdom with the appropriate administrative area type for UK constituent countries. The query returns exactly four results, matching the expected answer. The labels are optionally included in English, which is helpful for readability. Overall, the answer is accurate, complete, and the query follows best practices.

[Assistant] The official colors of the Dallas Cowboys are Blue and White. I will now provide the final answer.

[Tool] Stopped generation process

[User]
Feedback (status=refine):
The SPARQL query correctly retrieves the colors associated with the Dallas Cowboys, returning 'Blue' and 'White' as expected. However, the query returns many rows due to multiple language labels for the same colors, which is redundant for the user's question. To improve, the query should be refined to return only the English labels or just the color identifiers without multiple language labels. This will make the answer clearer and more concise. Additionally, the answer text should explicitly mention the colors as 'Blue and White' without language variations.

[Assistant] Thank you for the feedback. I will refine the SPARQL query to return only the English labels of the colors to avoid redundancy and make the answer clearer.

[Assistant] The refined query returns the English labels of the colors associated with the Dallas Cowboys. The colors are Blue, Navy Blue, Royal Blue, Silver, and White. I will now provide the final answer with these colors explicitly mentioned.

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.

[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.

[Assistant]
From the examples, it is clear that the property fb:people.person.spouse_s links a person to a marriage entity, and the marriage entity has a property fb:people.marriage.spouse that links to the spouse. The type of union can be filtered by fb:m.04ztj which represents marriage.

Next, I will search for the entity "Meredith Gray" in the knowledge graph to find the correct identifier for Meredith Gray in real life (not the character). Meredith Gray is a fictional character, so I need to find the real person who portrays Meredith Gray. I will search for "Meredith Gray" to find the related entities.

The entity fb:m.05np4c corresponds to Ellen Pompeo, the American actress who plays Meredith Gray.

Next, I will query who Ellen Pompeo is married to in real life using the marriage properties identified earlier.

[Assistant]
The query returned Ellen Pompeo herself as the spouse, which is incorrect. This suggests the marriage information might not be properly linked or represented in the knowledge graph for Ellen Pompeo.

I will try to find the spouse of Ellen Pompeo by searching for properties related to spouse or marriage for Ellen Pompeo.

No other items found

[Assistant] The property fb:people.person.spouse_s is the correct property for spouse or domestic partner for Ellen Pompeo. Since the previous query returned Ellen Pompeo herself, I will try to query the marriage entity and the spouse again but without the filter on the type of union to see if there is any other type of union recorded.

[Assistant]
The query still returns Ellen Pompeo herself as the spouse, which indicates that the knowledge graph might not have the correct spouse information for Ellen Pompeo.

I will now try to find the spouse of Ellen Pompeo by searching for objects of the property fb:people.person.spouse_s for Ellen Pompeo.
