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.

[Assistant]
From the examples, it is clear that the approach is to first identify the entity (William Morris) and then find the property related to "college" or "education" to get the college he attended.

Step 1: Search for the entity "William Morris" in the knowledge graph to get the correct entity identifier.
Step 2: Search for properties related to education or college for the identified entity.
Step 3: Construct a SPARQL query to get the college William Morris went to.

I will start with Step 1 and search for the entity "William Morris".

[Assistant] There is a property "played_by" (fb:base.gossipgirl.character.played_by) which is part of a character schema and links to an actor. This might be the property we are looking for to find the actor who plays a character. I will now check if this property is used for the entity Nicholas Newman (fb:m.0f22p8).

[Assistant] The property fb:base.gossipgirl.character.played_by is not used for Nicholas Newman. I will try a more general approach and list all properties of Nicholas Newman to see if there is any property related to the actor or played by.

Feedback (status=done):
The SPARQL query correctly identifies the actor who plays Nicholas Newman on The Young and the Restless by querying the performance data linking the character, series, and actor. The query returns the actor's identifier and multiple language labels for the actor's name, which is appropriate. The answer is complete and accurate, listing Joshua Morrow as the actor. No further refinement is necessary.

[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:

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 property "Portrayed in films" (fb:film.film_character.portrayed_in_films) seems relevant to find actors who played Lex Luthor. I will now write a SPARQL query to get the actors who played Lex Luthor using this property.

[Tool]
Got 237 rows and 2 columns, showing the first 5 and last 5 rows below:

[Assistant] I found multiple actors who have played Lex Luthor. The query results include actors such as James Marsters and William Hootkins among others. I will now finalize the answer with a SPARQL query that returns the actors who played Lex Luthor along with their names.

[Tool] Stopped generation process

[User]
Feedback (status=refine):
The SPARQL query correctly retrieves actors who have played Lex Luthor in films, but the result includes multiple entries for the same actor due to different language labels for their names. To improve, the query should be refined to return only one label per actor, preferably in English, or to group results to avoid duplicates. Additionally, the answer could mention that the query focuses on film portrayals and may not include TV or other media. Overall, the answer is correct but could be more precise and concise.

[Assistant] Thank you for the feedback. I will refine the SPARQL query to return only one English label per actor to avoid duplicates caused by multiple language labels. I will also clarify in the answer that the query focuses on film portrayals of Lex Luthor.

[Tool] Stopped generation process

[User]
Feedback (status=retry):
The SPARQL query is well-structured to find actors who played Lex Luthor in films, including retrieving their names. However, the query execution timed out, likely due to the FILTER on language or the dataset size. To improve, consider removing or simplifying the FILTER clause on ?actorName to reduce complexity. Also, verify that the entity fb:m.04q78 correctly identifies Lex Luthor in the dataset. Additionally, ensure that the query is optimized for performance, possibly by limiting results or restructuring the query. The answer should also clarify that it focuses on film portrayals only, as the question does not specify media type.

[Assistant] Thank you for the feedback. To address the timeout issue, I will simplify the query by removing the language filter on the actor names and instead use DISTINCT to avoid duplicates. I will also limit the number of results to 50 to improve performance. The answer will clarify that the query focuses on film portrayals of Lex Luthor.

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 question is about the first language spoken in Spain. To answer this, we need to identify the entity for Spain and then find properties related to languages spoken or historical languages in Spain. We should specifically look for the earliest or first language spoken.

Step 1: Search for the entity "Spain" in the knowledge graph.

There are two relevant properties for languages related to Spain:
1. Languages spoken (fb:location.country.languages_spoken)
2. Official Language (fb:location.country.official_language)

Since the question is about the first language spoken in Spain, we should look for historical or earliest languages. However, the properties we found are about languages spoken or official languages, which might not directly give the first language historically.

I will first query the languages spoken in Spain using the property fb:location.country.languages_spoken to see what languages are listed. This might give us some clues about the earliest languages.

[Tool]
Got 5 rows and 2 columns:
| language                        | languageLabel          |

[Assistant]
The languages spoken in Spain include Basque, Catalan, Galician, Occitan, and Spanish. Among these, Basque is known to be a very ancient language, predating the Roman influence and the spread of Latin (which evolved into Spanish).

To confirm if Basque was the first language spoken historically, I will check if there is any property or information about the first or earliest language spoken in Spain or historical languages of Spain. I will search for properties related to "first language" or "historical language" for Spain.

[Assistant]
There is no direct property for "first language" or "historical language" spoken in Spain in the knowledge graph. The closest relevant properties are "languages spoken" and "official language."

Given this, the best we can do is to provide the languages spoken in Spain and highlight that Basque is known historically as one of the oldest languages spoken in the region.

I will now prepare the final SPARQL query to return the languages spoken in Spain with their labels.

[User]
Feedback (status=refine):
The system correctly retrieved the languages spoken in Spain but did not specifically identify the first language spoken historically. The answer mentions Basque as one of the oldest languages, which is accurate, but the SPARQL query only lists current languages spoken without historical context. To improve, the query or answer should clarify or include historical linguistic data if available, or explicitly state that Basque is considered the oldest known language historically spoken in the region. Additionally, the answer could be more precise by stating that Basque predates Latin and the spread of Spanish in the area.

[Assistant] Thank you for the feedback. To improve the answer, I will clarify that the knowledge graph does not have a direct property for the first language historically spoken in Spain. However, based on linguistic and historical knowledge, Basque is considered the oldest known language historically spoken in the region, predating Latin and the spread of Spanish. I will update the answer accordingly while keeping the SPARQL query that lists the languages spoken in Spain.

[Tool] Stopped generation process

[User]
Feedback (status=refine):
The system correctly identified languages currently spoken in Spain but did not directly answer the question about the first language historically spoken in Spain. The answer explanation mentions Basque as the oldest known language, which is good, but the SPARQL query only retrieves current languages spoken in Spain without addressing historical context or the 'first language.' To improve, the query or explanation should clarify that the knowledge graph lacks direct historical language data and that the conclusion about Basque is based on external historical knowledge, not the query result. Additionally, the query could be refined to explicitly check for historical or ancient languages if such data exists in the knowledge graph.

[Assistant]
Thank you for the detailed feedback. I understand that the SPARQL query should explicitly attempt to find any historical or ancient languages related to Spain if such data exists in the knowledge graph. Meanwhile, the explanation should clearly state that the conclusion about Basque being the oldest language is based on external historical knowledge, as the knowledge graph lacks direct historical language data.

I will try to refine the query to check for any historical or ancient languages related to Spain by searching for properties or related entities that might indicate historical languages. If no such data is found, I will clearly state this in the answer.

First, I will search for entities related to "historical language" or "ancient language" in the context of Spain.

[Assistant]
The entity "Spain languages" (fb:m.02ddwjv) does not have properties related to historical or ancient languages. It mainly has metadata properties like type, license, name, length, source, and provenance.

Since there is no direct data about the first or historical language spoken in Spain in the knowledge graph, I will clarify this in the answer. I will also mention that based on external historical knowledge, Basque is considered the oldest known language historically spoken in the region.

I will finalize the answer with this clarification.

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=done):
The answer correctly identifies the institutions from which Morgan Freeman graduated, namely Pasadena Playhouse and Los Angeles City College. The SPARQL query returns the IRIs of these institutions along with their English labels, which aligns with the user's question about where Morgan Freeman graduated. The query is well-formed and the results are accurate and complete based on the knowledge graph data. No further refinement is necessary.
