[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#

hint: <http://www.bigdata.com/queryHints#
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.

No other items found

[Assistant]
There is a property "Notable for" (fb:common.topic.notable_for) which might describe what Francis Bacon is notable for, which can be considered as his contributions or achievements.

Step 6: I will query the values of the "Notable for" property for Francis Bacon (fb:m.030dr).

[Tool]
Got 1 row and 2 columns:
| notable        | notableLabel |
| -------------- | ------------ |

[Assistant]
Francis Bacon is notable for something represented by the entity fb:g.125cb1dqs, but there is no label available for this entity in the result.

Step 7: I will try to get a label for this notable entity fb:g.125cb1dqs to understand what it represents.

[Tool] Got no rows and 1 columns

[Assistant]
The notable entity fb:g.125cb1dqs does not have a label in the knowledge graph, so it is unclear what it represents.

Summary so far: Francis Bacon (fb:m.030dr) is an English philosopher and author known for his contributions through several important written works such as "The Instauratio Magna," "Novum organum," "De Augmentis Scientarum," and "New Atlantis." He had professions including author and spy. The "Notable for" property points to an unlabeled entity, so no additional information was obtained from that.

I will now finalize the answer with the information about his contributions as an author and philosopher with the mentioned works.

Feedback (status=refine):
The SPARQL query correctly retrieves languages spoken in Australia, including English as the primary language. However, the query returns many duplicate entries for the same language due to multiple labels in different languages. To improve, the query should be refined to return distinct languages and optionally include English labels only to avoid confusion. Also, the answer should explicitly mention English as the primary language and optionally list some other commonly spoken languages for completeness.

[Assistant]
Thank you for the feedback. I will refine the SPARQL query to return distinct languages spoken in Australia and include only English labels to avoid duplicates and confusion. I will also update the answer to explicitly mention English as the primary language and list some other commonly spoken languages for completeness.

Refined SPARQL query:
- Use DISTINCT to avoid duplicate languages.
- Use FILTER with LANG(?languageLabel) = "en" to get English labels only.

I will now execute the refined 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:

wikibase: <http://wikiba.se/ontology#

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.

The relevant properties for language related to the entity "Iran" are:
- Languages spoken (fb:location.country.languages_spoken)
- Official Language (fb:location.country.official_language)

Since the question asks for the national language, the property "Official Language" seems most appropriate. I will now query the official language(s) of Iran using the property fb:location.country.official_language.

Omar Epps acted in the following movies identified by their Freebase IRIs: fb:m.02vbbx0, fb:m.03hpjtv, fb:m.045xm7r, fb:m.04d5qln, fb:m.04hv85f, fb:m.0jzwwm, fb:m.0k0669, fb:m.0k0cb_, fb:m.0k66h_, fb:m.0k6ys4, and others. Unfortunately, the dataset does not provide human-readable movie titles for these films.

[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#

hint: <http://www.bigdata.com/queryHints#
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 movies is omar epps in?

[Assistant]
To answer the question "What movies is Omar Epps in?", I need to:

1. Identify the entity for Omar Epps in the Freebase knowledge graph.
2. Find the property that relates Omar Epps to movies he acted in.
3. Query the movies associated with Omar Epps using the identified property.

First, I will search for the entity "Omar Epps" in the Freebase knowledge graph.

[Tool]
Top 10 entity alternatives:

[Assistant]
I found the entity for Omar Epps as "fb:m.02_tv5" which is described as Omar Hashim Epps, an American actor. This is the correct entity for the actor Omar Epps.

Next, I will search for properties related to movies or films for this entity to find the appropriate property that links Omar Epps to movies he acted in. I will search for properties related to "film" or "movie" for the entity fb:m.02_tv5.

[Assistant]
I found relevant properties related to films for Omar Epps (fb:m.02_tv5):
- Films appeared in (fb:film.person_or_entity_appearing_in_film.films)
- Film performances (fb:film.actor.film)

The property "Film performances" (fb:film.actor.film) seems to directly link to films where he acted, which is the most relevant for the question.

Next, I will query the movies Omar Epps acted in using the property fb:film.actor.film. I will also try to get the labels of the movies for better readability.

[Assistant] I retrieved 24 films that Omar Epps acted in, but the labels (names) of the films are missing in the results. To improve the query, I will try to get the English labels of the films more reliably by using OPTIONAL with rdfs:label and filtering for English language labels again. I will also increase the limit to 50 to get more results if available.

[Assistant]
The labels for the films are still missing in the results. This might be due to the labels not being available in English or not being present in the dataset.

I will now try to get the "name" property (fb:type.object.name) of the films as an alternative to rdfs:label to see if that provides the movie names. I will query the films Omar Epps acted in along with their names.

[Assistant]
The "name" property for the films is also missing in the results. It seems that the movie titles are not available in the dataset for these films.

I will now provide the list of movie IRIs (identifiers) that Omar Epps acted in as the answer, since the labels or names are not available.

Feedback (status=refine):
The SPARQL query correctly retrieves the movies Omar Epps acted in by using the property fb:film.actor.film. However, the answer only provides Freebase IRIs without any movie titles, which is not very user-friendly. The query should be refined to also retrieve the movie titles using the rdfs:label property or another appropriate property for movie names. This will make the answer more informative and understandable for the user.

[Assistant] Thank you for the feedback. I understand that providing movie titles along with the IRIs is important for user-friendliness. I previously tried to get rdfs:label and fb:type.object.name for the movies but did not get any results. I will now try to get the movie titles using an alternative property commonly used for names in Freebase: fb:common.topic.alias. I will refine the query to retrieve the movies Omar Epps acted in along with their aliases as movie titles.

| fb:m.0k6ys4  |       |

[Assistant]
The property fb:common.topic.alias also did not return movie titles for the films Omar Epps acted in.

I will try one more approach: using the property fb:type.object.name without language filtering to see if any names are available in any language. I will query the movies Omar Epps acted in along with their names without filtering by language.

[Assistant]
The property fb:type.object.name without language filtering also did not return any movie titles for the films Omar Epps acted in.

It appears that the dataset does not contain movie titles for these films, or the titles are not linked with these properties.

I will provide the list of movie IRIs (identifiers) that Omar Epps acted in as the best possible answer given the dataset limitations.

Feedback (status=refine):
The SPARQL query correctly retrieves the movies Omar Epps acted in by using the property fb:film.actor.film. However, the answer only provides Freebase IRIs without any human-readable movie titles, which is not very user-friendly. To improve, the query should be extended to optionally retrieve the rdfs:label or another property that provides the movie title or name, so the answer can include movie titles alongside their IRIs. This will make the answer more informative and understandable for the user.

[Assistant]
I understand the importance of providing human-readable movie titles alongside the Freebase IRIs for better user-friendliness. Since previous attempts to retrieve movie titles using rdfs:label, fb:type.object.name, and fb:common.topic.alias did not yield results, I will now try to retrieve the movie titles using the property fb:film.film.initial_release_date to confirm the films and then attempt to get their labels again. Sometimes, linking to other properties can help in retrieving labels.

I will write a query to get the movies Omar Epps acted in, their initial release dates, and optionally their rdfs:label to see if that helps in getting movie titles.

[Assistant]
The query returned the movies Omar Epps acted in along with their initial release dates, but the movie titles (rdfs:label) are still missing.

It seems that the dataset does not have movie titles or labels for these films, which limits the ability to provide human-readable movie names.

Given these limitations, I will provide the list of movie IRIs that Omar Epps acted in as the best possible answer.
