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:

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] who plays eowyn in lord of the rings?

[Assistant] From the examples, the approach is to find the entity for Éowyn as a film character and then find the actor who portrayed her in the Lord of the Rings films. I will first search for the entity Éowyn in the freebase knowledge graph.

Top 10 entity alternatives:

10. Princess Éowyn (fb:m.0lzxk92)

[Assistant] The entity for Éowyn as a film character is fb:m.0gynx. Now I will write a SPARQL query to find the actor who played Éowyn in the Lord of the Rings films using the properties film_character.portrayed_in_films and film.performance.actor.

[Tool] Stopped generation process

[User]
Feedback (status=done):
The SPARQL query correctly retrieves the actor who portrayed Éowyn in the Lord of the Rings films from the Freebase knowledge graph. It uses the appropriate properties to link the character to film performances and then to the actor. The query also optionally retrieves the actor's English label, which is helpful for readability. The returned answer, Miranda Otto, is accurate and complete. No further refinement is necessary.

According to Freebase data, Hayden Christensen physically portrayed Darth Vader in Star Wars Episode III: Revenge of the Sith (Episode 3). The only voice acting performance recorded for Darth Vader in this film is for the German language by Reiner Schöne. The iconic voice actor James Earl Jones does not have a recorded voice performance for Darth Vader in Episode 3 in Freebase, and the voice actor information for the original English version is not available in Freebase.

[Assistant]
From the similar examples, it appears that the character Darth Vader is represented by the entity fb:m.0f2y0 and the film Star Wars Episode III: Revenge of the Sith is represented by fb:m.0fdv3 in Freebase. The property for the actor who performed a character in a film is fb:film.performance.actor and the property linking the performance to the character is fb:film.performance.character.

[Assistant] There is no specific property related to "voice" for the character Darth Vader in Freebase.

There is only one performance listed for Darth Vader in Star Wars Episode III: Revenge of the Sith, and the actor is Hayden Christensen. There is no separate voice actor listed in the data.

I will now finalize the answer with this information.

Feedback (status=retry):
The SPARQL query retrieves the actor who played the character Darth Vader in Star Wars Episode III: Revenge of the Sith, but it does not specifically retrieve the voice actor. Hayden Christensen physically portrayed Anakin Skywalker (who becomes Darth Vader), but the voice of Darth Vader in Episode III was provided by James Earl Jones. The query should be refined to specifically find the voice actor for the character Darth Vader in that episode, if such data is available. Otherwise, the answer is misleading as it confuses the physical actor with the voice actor.

[Assistant]
Thank you for the feedback. I understand the distinction between the physical actor and the voice actor for Darth Vader in Episode III. I will now try to find if there is a specific property or way to identify the voice actor for the character Darth Vader in Star Wars Episode III: Revenge of the Sith in Freebase.

I will search for properties related to "voice actor" or "voice" for the film Star Wars Episode III: Revenge of the Sith (fb:m.0fdv3) to see if there is any relevant property that can help distinguish the voice actor.

There is a property called "dubbing performances" (fb:film.film.dubbing_performances) for the film entity, which might be related to voice actors or voice performances.

[Assistant]
The dubbing performance fb:m.04dmkc9 is for the German language and the actor is Reiner Schöne. This indicates voice actors for dubbing in other languages are recorded, but it does not show the original English voice actor.

I will now try to find if there is a dubbing performance or voice actor for the original English language for Darth Vader in this film. I will search for other dubbing performances for this film.

[Assistant]
James Earl Jones has performances as Darth Vader in several Star Wars films and specials, including Return of the Jedi, Star Wars Episode V: The Empire Strikes Back, and the original Star Wars film. However, there is no record of him performing as Darth Vader in Star Wars Episode III: Revenge of the Sith (Episode 3).

Based on this data, it appears that James Earl Jones did not voice Darth Vader in Episode 3 according to Freebase, even though he is known as the iconic voice of Darth Vader in other Star Wars films.

I will now finalize the answer with this clarification.

[User]
Feedback (status=refine):
The SPARQL query correctly identifies Hayden Christensen as the actor who portrayed Darth Vader in Episode 3, but it does not distinguish between physical portrayal and voice acting. The user's question specifically asks for the voice actor of Darth Vader in Episode 3. According to known information, James Earl Jones is the iconic voice of Darth Vader in most films, but Freebase data does not show him as the voice actor for Episode 3. The query should be refined to specifically look for voice acting roles or voice performances related to Darth Vader in Episode 3, if such data is available. Additionally, the answer should clarify that Hayden Christensen physically portrayed Darth Vader, but the voice actor information is not found or is different. This would provide a more precise and complete answer to the user's question.

[Assistant]
I will refine the query to specifically look for voice acting or dubbing performances related to Darth Vader in Star Wars Episode III: Revenge of the Sith (fb:m.0fdv3). Since there is a property for dubbing performances (fb:film.film.dubbing_performances), I will explore if there are any voice performances (including original language) linked to this film and character.

If no voice actor is found for the original English version, I will clarify in the answer that Hayden Christensen physically portrayed Darth Vader, but the voice actor information is not available or different in Freebase.

The only dubbing performance for Darth Vader in Star Wars Episode III: Revenge of the Sith is for the German language, with Reiner Schöne as the voice actor. There is no record of a separate voice actor for the original English version in Freebase.

I will now finalize the answer clarifying that Hayden Christensen physically portrayed Darth Vader in Episode 3, but the voice actor information for the original English version is not available in Freebase. The known iconic voice actor James Earl Jones does not have a recorded voice performance for Darth Vader in Episode 3 in Freebase.

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 similar examples, it seems that the property fb:location.location.containedby is used to find the larger location or region that a place is part of. To answer the question "what part of the country is Ohio considered?" we can try to find what larger location Ohio is contained by using this property.

[Assistant] The search for properties related to "region" for Ohio did not return a direct property indicating the part of the country Ohio is considered. However, from the similar examples, the property fb:location.location.containedby was used to find the larger location or region a place is part of.

Ohio is contained by several regions including the Northwest Territory, Eastern United States, East North Central States, Contiguous United States, United States of America, United States with Territories, and Midwestern United States. Among these, the most specific and commonly used part of the country Ohio is considered is the "Midwestern United States."

I will now provide the final answer with the relevant SPARQL query.

[User]
Feedback (status=done):
The answer correctly identifies Ohio as part of the Midwestern United States, which is the most relevant and common regional classification for the state. The SPARQL query retrieves multiple broader regions containing Ohio, but the Midwestern United States is the specific part of the country typically used to describe Ohio's location. The query and answer are appropriate and complete for the user's question.

The similar examples indicate that the Baltimore Orioles are represented by the entity fb:m.01d6g in Freebase, and the property fb:sports.sports_team.championships links to the championships or World Series events they participated in.

Next, I will query the years the Baltimore Orioles went to the World Series using this entity and property. I will retrieve the championship events and then extract the year from those events.

[Assistant] The property fb:sports.sports_league_championship_event.season_year did not return any results for the year of the championship events. I will try to find other properties related to the championship events that might indicate the year or date. First, I will look at the properties of one of the championship events of the Orioles to find a suitable property for the year.

[Assistant]
The championship event "1983 World Series" has a property fb:time.event.start_date with the value "1983-10-11" which indicates the start date of the event. This can be used to extract the year.

I will now query all championship events of the Baltimore Orioles and their start dates to get the years they went to the World Series.

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 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.

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

[Tool]
Example 1:
Question:
what country does nike operate in?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.0lwkh ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.0lwkh fb:organization.organization.headquarters ?y .
  ?y fb:location.mailing_address.country ?x .
}

Using entities:

[Assistant]
From the examples, it seems that for companies like Starbucks, the property related to what they sell is linked to cuisine or product types. For Nike, we should first identify the entity for Nike and then look for properties related to products or items they sell.

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

Feedback (status=refine):
The SPARQL query correctly retrieves product lines associated with Nike, which is relevant to the question about the kinds of products Nike sells. However, the answer lists specific product lines (e.g., 'LeBron 11 Low', 'Nike Considered', 'Nike Air Max') which are individual product lines or models rather than broad product categories. The question seems to ask for general types or categories of products (e.g., footwear, apparel, sports equipment) rather than specific product lines. To improve, the query should be refined or extended to retrieve broader product categories or types of products Nike sells, if available in the knowledge graph. Additionally, including labels in the query is good, but the answer should clarify that these are product lines, not product categories, to avoid confusion.

[Assistant]
Thank you for the feedback. I understand that the question asks for general types or categories of products Nike sells, not specific product lines. I will now try to find broader product categories or types related to Nike's products.

[Assistant] The products linked to Nike are still of type "Company-product relationship," which represent relationships rather than broad product categories. I will now try to find if there is a property related to product categories or types for these company-product relationships. I will explore properties of one of these product relationship entities to see if there is a property indicating product category or type.

[Assistant]
The consumer product entity fb:m.07s_fy has the type "Product category" (fb:business.product_category) and also more specific types like "Sports Equipment" and "Shoe." This indicates that we can get broader product categories from these consumer product entities.

[Assistant]
The broader product categories for Nike's products include "Sports Equipment" and "Shoe," which are relevant general product types. Other types like "Man-made Thing," "Topic," "Inanimate," etc., are more generic and not specific product categories.

I will finalize the answer by stating that Nike sells products in general categories such as sports equipment and footwear (shoes).
