[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/

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 are the four nations of the united kingdom?

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

[Tool]
Example 1:
Question:
where did roger moore live?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.017lqp ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.017lqp fb:people.person.places_lived ?y .

[Assistant]
From the examples, we see that to find parts or members of an entity, we can look for properties related to membership or parts. In this case, the "four nations of the United Kingdom" suggests we want to find entities that are part of or members of the United Kingdom.

Step 1: Search for the entity "United Kingdom" in Freebase to get its identifier.
Step 2: Search for properties of the United Kingdom that might indicate its constituent nations or parts.
Step 3: Query the entities that are parts or members of the United Kingdom.

Let's start with step 1 and search for the entity "United Kingdom".

[Tool]
Top 10 entity alternatives:
1. 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
2. United Kingdom (fb:m.0g9jnqz)

No other items found

[Assistant]
The property "Contains" (fb:location.location.contains) looks promising as it is part of the Location schema and links to other locations. This might be used to indicate the constituent nations of the United Kingdom.

Next, let's query the entities that the United Kingdom (fb:m.07ssc) contains.

[Tool]
Got 40,717 rows and 2 columns, showing the first 5 and last 5 rows below:

[Assistant]
No suitable property related to "located in" for countries or nations is found. Let's try a different approach: search for the four nations of the United Kingdom directly as entities to see if they are linked to the United Kingdom entity.

Let's search for the entity "England" first, as it is one of the four nations.

The property "Contained by" (fb:location.location.containedby) looks promising as it is part of the Location schema and links to a Location. This might indicate that England is contained by the United Kingdom.

Let's query the value of the property "Contained by" for England (fb:m.02jx1).

[Tool]
Got 3 rows and 2 columns:

[Assistant]
England (fb:m.02jx1) is contained by the United Kingdom (fb:m.07ssc) and Great Britain (fb:m.034cm). This confirms that the "contained by" property can be used to find the four nations of the United Kingdom.

Let's query all entities that are contained by the United Kingdom (fb:m.07ssc) and filter for those that are countries or nations. We can check their types to ensure they are nations.

[Tool]

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:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.06cmp ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.06cmp fb:fictional_universe.fictional_setting.languages ?x .
}

Using entities:
Roman Empire, also known as IMPERIVM ROMANVM (fb:m.06cmp): The Roman Empire was the post-Republican period of the ancient R...an's victory, the size of the Empire was dramatically increased., has type Country

Using properties:
Languages (fb:fictional_universe.fictional_setting.languages): links to type Language in fiction, part of Fictional Setting schema

Example 2:
Question:

    FILTER ( xsd:datetime ( ?sk3 ) <= "2015-08-10" ^^ xsd:dateTime )

  )
}

Using entities:

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, it seems that to find people from a certain place, we can look for people with a property related to places lived or place of birth. The property "places lived" was used in the example about where Danny Ainge lives. However, for "from Barbados," it might be more accurate to look for place of birth or nationality.

Next, I will search for the entity "Barbados" in the knowledge graph to get its identifier. Then, I will search for properties related to people and Barbados to find the appropriate property to use in the query.

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/

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.

[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#
rdfs: <http://www.w3.org/2000/01/rdf-schema#
owl: <http://www.w3.org/2002/07/owl#

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] The examples show how to find relationships of a person such as teams they played for or places they lived. Now I will search for the entity "Meredith Gray" in the knowledge graph to identify the correct entity representing Meredith Gray. Then I will look for properties related to marriage or spouse to find who Meredith Gray is married to in real life.

[Assistant]
The search for "Meredith Gray" did not return an entity representing the character or person Meredith Gray from the TV show Grey's Anatomy. The closest match is "Gray Meredith" which is a fictional character from the film A Bill of Divorcement, which is not relevant.

I will try searching for "Meredith Grey" (with an 'e' in Grey) as that is the correct spelling of the character's name from the TV show. Then I will look for marriage or spouse properties.

The property "Married To" (fb:fictional_universe.fictional_character.married_to) is available for the fictional character Meredith Grey. However, this property refers to the fictional character's marriage within the TV show, not the real-life marriage of the actress.

Since the user asked about Meredith Grey's real-life marriage, I need to find the real person who plays Meredith Grey and check their marital status. I will search for the actress who plays Meredith Grey.
