[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.

[User] What is the occupation of the artist that went on To Be Loved Tour?

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

[Tool]
Example 1:
Question:
What style of music did the artist that went to Cry of Love Tour play?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != ?c ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) ?c fb:music.artist.concert_tours fb:m.04gkgs_ .
  ?c fb:music.artist.genre ?x .
}

Using entities:
The Cry of Love Tour (fb:m.04gkgs_): The Cry of Love Tour was a concert tour by American rock singer-...and Billy Cox was often billed as "The Jimi Hendrix Experience"., has type Concert tour

Using properties:
Concert Tours (fb:music.artist.concert_tours): part of Musical Artist schema, links to type Concert tour
Musical Genres (fb:music.artist.genre): part of Musical Artist schema, links to type Musical genre

Example 2:
Question:
What did the lead artist that went on the Believe Tour do?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != ?c ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) ?c fb:music.artist.concert_tours fb:m.0j_3p6t .
  ?c fb:music.artist.track_contributions ?y .
  ?y fb:music.track_contribution.role ?x .
}

Using entities:
Believe Tour (fb:m.0j_3p6t): The Believe Tour was the second concert tour by Canadian singer ... Worldwide Tours—Mid Year"; earning $69.9 million from 67 shows., has type Concert tour

Using properties:
Concert Tours (fb:music.artist.concert_tours): part of Musical Artist schema, links to type Concert tour
Recording contributions (fb:music.artist.track_contributions): links to type Recording contribution, part of Musical Artist schema
Role (fb:music.track_contribution.role): links to type Musical Performance Role, part of Recording contribution schema

Example 3:
Question:
What genre of music is performed by the artist who headliens the Cry of Love tour?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != ?c ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) ?c fb:music.artist.concert_tours fb:m.04gkgs_ .
  ?c fb:music.artist.genre ?x .
}

Using entities:
The Cry of Love Tour (fb:m.04gkgs_): The Cry of Love Tour was a concert tour by American rock singer-...and Billy Cox was often billed as "The Jimi Hendrix Experience"., has type Concert tour

Using properties:
Concert Tours (fb:music.artist.concert_tours): part of Musical Artist schema, links to type Concert tour
Musical Genres (fb:music.artist.genre): part of Musical Artist schema, links to type Musical genre

[Assistant]
From the examples, I see that the property fb:music.artist.concert_tours links an artist to a concert tour, and the property fb:people.person.occupation or similar might be used to find the occupation of a person or artist.

Next, I will search for the entity "To Be Loved Tour" to find its identifier in the knowledge graph.

[Assistant]
From the examples, I see that Tupac Amaru Shakur is identified as fb:m.07pzc in Freebase. The property for film performances is fb:film.actor.film, and the property for the film in the performance is fb:film.performance.film. The initial release date of the film is given by fb:film.film.initial_release_date.

I will now write a SPARQL query to find the latest film starring Tupac to be released using these properties and entity.

Feedback (status=done):
The SPARQL query correctly retrieves the latest film starring Tupac by ordering the films by their initial release date in descending order and limiting the result to one. The query uses the correct entity for Tupac and the appropriate properties to find films he starred in and their release dates. The answer 'Gang Related,' released on October 8, 1997, is accurate based on the query result. The query also optionally retrieves the film label in English, which is helpful for readability. Overall, the output is correct and complete.

[User] What years' World Series were won by the sports team whose owner is Frank McCourt?

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

[Tool]
Example 1:
Question:
When did sports team owner Frank McCourt's team last win the Championship?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != ?c ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) ?c fb:sports.professional_sports_team.owner_s fb:m.05w2rj .

  ?x fb:time.event.end_date ?sk0 .
}
ORDER BY DESC ( xsd:datetime ( ?sk0 ) )
LIMIT 1

Using entities:
Frank McCourt (fb:m.05w2rj): Frank H. McCourt is an American businessman, president of the Mc...ool of Public Policy, the ninth school of Georgetown University., has type Sports Team Owner

End date (fb:time.event.end_date): links to type Date/Time, part of Event schema

Example 2:
Question:
In what year did team owner Ken Kendrick's sports team with the World Series?

SPARQL:
SELECT DISTINCT ?x WHERE {

[Assistant]
From the similar examples, I see that the entity for Frank McCourt is fb:m.05w2rj and the property for owner of a sports team is fb:sports.professional_sports_team.owner_s. The property for championships won by a sports team is fb:sports.sports_team.championships. The championships have an end date property fb:time.event.end_date which can be used to get the year.

I will now write a SPARQL query to find the years of the World Series won by the sports team whose owner is Frank McCourt.

[Tool]
Got 5 rows and 1 column:

Feedback (status=refine):
The SPARQL query correctly identifies the years of the World Series won by the sports team owned by Frank McCourt. However, it does not explicitly restrict the championships to the World Series, which is a specific championship event in baseball. To improve accuracy, the query should include a filter or condition to ensure that only World Series championships are considered. Additionally, it would be helpful to include the team label and the championship label optionally to provide more context in the results. Overall, the answer is sensible but could be refined for precision and clarity.

[Assistant] Thank you for the feedback. To refine the query, I will add a condition to ensure that the championships are specifically World Series events. I will also include optional labels for the team and the championship for better context in the results. I will first search for the entity representing the World Series championship event to use it as a filter.

[Assistant] The entity fb:m.0fjp3 represents the World Series as the annual championship series of Major League Baseball. I will use this entity to filter the championships to only include World Series events. I will also add optional labels for the team and the championship in the query.

[Tool] Got no rows and 3 columns

[Assistant] The query returned no results when filtering championships by the World Series entity type fb:m.0fjp3. It is possible that the championships are not directly typed as World Series in the data. I will try a different approach by checking if the championship label contains "World Series" instead of filtering by type. I will keep the optional labels for team and championship.

Feedback (status=refine):
The answer correctly identifies the Los Angeles Dodgers as the team owned by Frank McCourt and lists the years they won the World Series. However, the SPARQL query returns multiple language labels for the same championship years, resulting in redundant rows. The query should be refined to return only one label per championship or to group results by year to avoid duplicates. Additionally, it would be clearer to return only the years of the World Series wins, as the question specifically asks for the years. Overall, the answer is correct but the query can be optimized for clarity and conciseness.

[Assistant] Thank you for the feedback. To optimize the query, I will modify it to return only distinct years of the World Series wins without multiple language labels. I will remove the labels and group by year to avoid duplicates, focusing on the years as requested. I will now refine the query accordingly.

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:

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.

Feedback (status=refine):
The SPARQL query correctly identifies the actors who played Batgirl, the parent of James Gordon, Jr., and returns their identifiers and names. However, the query returns multiple language variants of the actor names, which is redundant and could be simplified. It would be better to restrict the returned actor names to a single language (e.g., English) or to return only the actor identifiers without multiple language labels. Additionally, the answer should clarify that these actors portrayed Batgirl in films, as the property used is related to film performances. Overall, the answer is correct but could be improved for clarity and conciseness.

[Assistant] Thank you for the feedback. I will refine the SPARQL query to restrict the actor names to English language only to avoid multiple language variants. I will also clarify in the answer that these actors portrayed Batgirl in films.

[Tool] Stopped generation process

[User]
Feedback (status=refine):
The SPARQL query is logically structured to find actors who portrayed Batgirl, the parent of James Gordon, Jr., but it failed to execute due to a timeout, likely caused by the FILTER on actor names or the query complexity. To improve, consider simplifying the query by removing or optimizing the FILTER clause on actor names, or limit the query to a smaller scope if possible. Also, ensure that the entity identifiers used are correct and that the property paths accurately reflect the relationships. The answer provided lists actors, but since the query did not execute successfully, the answer cannot be verified. Refining the query to successfully execute will help confirm the correctness of the answer.

[Assistant] I will simplify the query by removing the FILTER clause on actor names to avoid timeout issues and keep the optional actor names without language filtering. This should reduce query complexity and allow it to execute successfully.

From the examples, I see that the Tsakhur language is identified as fb:m.027bj_4 in Freebase. The examples also show how to find the country where a language is spoken using the property fb:location.country.languages_spoken.

Now, I need to find the national anthem of the country where Tsakhur is spoken. I will first check the property related to the national anthem for a country in Freebase. I will search for properties related to "national anthem" for the entity type country.

[Assistant]
The property fb:location.country.national_anthem is the relevant property for the national anthem of a country.

Next, I will write a SPARQL query to find the country where Tsakhur (fb:m.027bj_4) is spoken and then retrieve the national anthem of that country using the property fb:location.country.national_anthem. I will also try to get the label of the national anthem for better readability.

[Assistant]
The query returned the national anthem entity fb:m.0bwnwv9 for the country where Tsakhur is spoken, but it did not return an English label for the anthem.

I will now query the label of this national anthem entity fb:m.0bwnwv9 to get its English name.

Feedback (status=done):
The SPARQL query correctly identifies the person who inspired F. Scott Fitzgerald and died the earliest by ordering the inspirers by their date of death and limiting the result to one. The query returns the identifier, label, and date of death of the inspirer, which is John Keats, who died on February 23, 1821. The answer is accurate and complete based on the knowledge graph data. No further refinement is necessary.
