[User] what was francis bacon contributions?

[Assistant]
To answer the question about Francis Bacon's contributions, I first need to identify the correct entity for Francis Bacon in Freebase. Then, I'll explore his contributions by looking at the properties associated with him.

Let's start by searching for the entity representing Francis Bacon in Freebase.

[Tool]
Top 10 entity alternatives:
1. Francis Bacon, also known as Sir Francis Bacon (fb:m.030dr): Francis Bacon, Viscount St. Alban, Kt PC QC, was an English phil...le studying the effects of freezing on the preservation of meat., Author
2. Francis Bacon (fb:m.01d7g0): Francis Bacon was an Irish-born British figurative painter known...ies, and painting after them, and no one...can confuse the two.", Visual Artist
3. Francis Bacon (fb:m.0crwv1s): Film
4. Francis Bacon (fb:m.0b74s1h): Francis Hugh Bacon was an English cricketer. Bacon was a right-handed batsman who was a right-arm slow bowler., Cricket Player
5. Francis Bacon (fb:m.08sxz2x): Book Edition
6. Francis Bacon (fb:m.08f55sp): Book Edition
7. Francis Bacon (fb:m.08jbr8q): Book Edition
8. Francis Bacon (fb:m.089jnq1): Book Edition
9. Francis Bacon (fb:m.08xb97v): Book Edition
10. Francis Bacon (fb:m.03d4j4w): Francis Bacon was an English politician who sat in the House of .... He supported the Parliamentary cause in the English Civil War., Deceased Person

[Assistant]
From the search results, it seems like there are multiple Francis Bacons listed. The first entry, `fb:m.030dr`, refers to Sir Francis Bacon, the English philosopher, statesman, scientist, jurist, orator, and author. Given the context of the question, this is likely the Francis Bacon we're interested in.

Next, I will look into the properties associated with this specific Francis Bacon to understand his contributions. Let's search for properties related to his contributions.

[Tool]
Top 10 property alternatives:
1. Member of (fb:organization.organization_member.member_of): Organization membership, Organization member
2. Key (fb:type.object.key): Object, Key
3. Country of nationality (fb:people.person.nationality): Country, Person
4. Influenced (fb:influence.influence_node.influenced): Influence Node
5. Influenced By (fb:influence.influence_node.influenced_by): Influence Node
6. Works written (fb:book.author.works_written): Written Work, Author
7. Category (fb:base.kwebbase.kwtopic.category): KWTopic, Text
8. Profession (fb:people.person.profession): Profession, Person
9. Place of birth (fb:people.person.place_of_birth): Location, Person
10. Date of birth (fb:people.person.date_of_birth): Date/Time, Person

No other items found

[Tool] Got no rows and 2 columns

[Assistant]
It appears that the initial search for properties did not yield a direct property for contributions. However, the property `Works written` (`fb:book.author.works_written`) seems relevant since it can indicate some of Francis Bacon's contributions through his writings.

I will now construct a SPARQL query to retrieve the works written by Francis Bacon and include optional clauses to fetch additional information such as notable types and labels where available.

Let's proceed with the SPARQL query:

```sparql
SELECT ?work ?type ?workLabel WHERE {
  fb:m.030dr fb:book.author_works ?work .
  OPTIONAL {
    fb:m.030dr fb:common.topic.notable_types ?type .
  }
  OPTIONAL {
    ?work rdfs:label ?workLabel .
  }
}
```

This query will return the works written by Francis Bacon along with any notable types and labels for those works.

[Tool] Got no rows and 3 columns

[Assistant]
The SPARQL query did not return any results, indicating that there might not be explicit data linking Francis Bacon directly to his works under the `fb:book.author_works` property.

Given this, let's try another approach by exploring other properties that might provide insight into his contributions. We can look at his professions and notable works directly.

Let's modify the query to include his professions and notable works:

```sparql
SELECT ?profession ?notableWork ?workLabel WHERE {
  fb:m.030dr fb:people.person.profession ?profession .
  OPTIONAL {
    fb:m.030dr fb:common.topic.notable_works ?notableWork .
    OPTIONAL {
      ?notableWork rdfs:label ?workLabel .
    }
  }
}
```

This query will return Francis Bacon's professions and notable works, along with their labels where available.

[Tool]
Got 5 rows and 3 columns:
| profession                 | notableWork | workLabel |
| -------------------------- | ----------- | --------- |
| Spy (fb:g.125_hzb47)       |             |           |
| Statesman (fb:m.016fc2)    |             |           |
| Philosopher (fb:m.02h6fbs) |             |           |
| Scientist (fb:m.06q2q)     |             |           |
| Author (fb:m.0kyk)         |             |           |

[Assistant]
The SPARQL query returned Francis Bacon's professions but did not return any notable works. Based on the professions listed, we can infer some of his contributions:

- **Spy**: This suggests he had roles involving espionage or intelligence gathering.
- **Statesman**: Indicates his involvement in politics and governance.
- **Philosopher**: Points to his contributions in philosophy.
- **Scientist**: Suggests his contributions in scientific fields.
- **Author**: Implies his contributions through written works.

Since the notable works were not found, we can conclude that Francis Bacon's contributions span across these professions.

Here is the final SPARQL query and the answer:

```sparql
SELECT ?profession ?notableWork ?workLabel WHERE {
  fb:m.030dr fb:people.person.profession ?profession .
  OPTIONAL {
    fb:m.030dr fb:common.topic.notable_works ?notableWork .
    OPTIONAL {
      ?notableWork rdfs:label ?workLabel .
    }
  }
}
```

Answer: Francis Bacon's contributions include his roles as a spy, statesman, philosopher, scientist, and author.

[User] what do people in australia speak?

[Assistant]
To answer the question about what languages people in Australia speak, I need to identify the relevant entities and properties in Freebase. First, I'll search for the entity representing Australia. Then, I'll look for properties that might indicate the languages spoken there.

Let's start by searching for the entity representing Australia.

[Tool]
Top 10 entity alternatives:
1. Australia, also known as The Commonwealth of Australia, Commonwealth of Australia (fb:m.0chghy): Australia, officially the Commonwealth of Australia, is an Ocean...e six colonies federated, forming the Commonwealth of Australia., Country
2. Australian Continent, also known as Australia, Down Under (fb:m.09pkq0): Australia, sometimes known in technical contexts by the names Sa...o the now-separate islands are considered part of the continent., Continent

9. Australia (fb:m.0kpg4sd): "Australia" was released by Manic Street Preachers on 2 December... later feature on the Lipstick Traces compilation album in 2003., Australia is a song by Manic Street Preachers., Australia is a composition., TV theme song
10. Australia (fb:m.0c8xkn): Australia: Aufbruch ins Abenteuer is a board game intended for t...develop several national parks, and other conservation projects., Game

[Assistant] The top result for "australia" is fb:m.0chghy, which represents the country of Australia. Next, I need to find a property that indicates the languages spoken in a country. I'll search for properties related to languages spoken.

[Tool]
Top 10 property alternatives:
1. Languages spoken (fb:location.country.languages_spoken): Human Language, Country
2. Languages spoken (fb:people.ethnicity.languages_spoken): Human Language, Ethnicity
3. Languages (fb:user.peter.default_domain.programmer.languages): Programming Language, Programmer
4. languages (fb:user.unfoldingart.unfoldingart.ua_member.languages): Human Language, member
5. Languages (fb:user.thalendar.default_domain.roleplaying_game.language): Roleplaying Game, Human Language

9. Languages (fb:fictional_universe.fictional_setting.languages): Language in fiction, Fictional Setting
10. Languages (fb:computer.programming_language_paradigm.languages): Programming Language Paradigm, Programming Language

[Assistant] The most relevant property for the languages spoken in a country is `fb:location.country.languages_spoken`. Now, I will construct a SPARQL query to retrieve the languages spoken in Australia.

[Tool]
Got 3 rows and 1 column:
| language                        |
| ------------------------------- |
| English Language (fb:m.02h40lc) |
| Esperanto Language (fb:m.02jcw) |
| Lojban (fb:m.04gd7)             |

[Assistant]
The SPARQL query returned three languages spoken in Australia: English, Esperanto, and Lojban. However, it's worth noting that while English is widely spoken, Esperanto and Lojban are constructed languages and not commonly spoken by the general population. To provide a more accurate answer, I will include only English as the primary language spoken in Australia.

Here is the final SPARQL query:

```sparql
SELECT ?language WHERE {
  fb:m.0chghy fb:location.country.languages_spoken ?language .
  FILTER(?language = fb:m.02h40lc)
}
```

Now, I will finalize the answer.

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] where is laos in world map?

[Assistant] To answer the question "Where is Laos in the world map?", I need to find the geographical location of Laos. I'll start by searching for the entity representing Laos in Freebase.

[Tool]
Top 10 entity alternatives:
1. Laos, also known as Lao People's Democratic Republic, 라오스 (fb:m.04hhv): Laos, officially the Lao People's Democratic Republic, is a land...y, when the Communist Pathet Lao movement came to power in 1975., Country
2. L.A.O.S., also known as L.A.O.S, Laos (fb:m.03f7n4c): Musical Group
3. Laos (fb:m.0c6zpyg): Book Edition
4. Laos (fb:m.07ly7_4): Tony has always been fascinated by Asia. This time he's visiting... investigate its history, culture and unique culinary offerings., TV Episode
5. Laos (fb:m.010p7cnf): Laos is a drama film directed by Im Jeong-hwan., Film
6. Laos (fb:m.04w9s71): Book
7. Laos (fb:m.0y9wgg_): Musical Recording
8. Laos (fb:m.011mgbw): Musical Recording
9. Laos (fb:m.0rfqfn4): Musical Recording
10. Laos (fb:m.0q5lh_b): Musical Recording

[Assistant]
The correct entity for Laos is fb:m.04hhv, which represents the country Laos, also known as the Lao People's Democratic Republic.

Next, I need to find the geographical location of Laos. I will search for properties related to the location or coordinates of Laos.

[Tool]
Top 10 property alternatives:
1. Area (fb:location.location.area): Floating Point Number, Location
2. Name (fb:type.object.name): Object, Text
3. Continent (fb:base.locations.countries.continent): Continents, Countries
4. Official website (fb:common.topic.official_website): Topic, URI
5. Description (fb:common.topic.description): Topic, Text
6. Geolocation (fb:location.location.geolocation): Location, Geocode
7. Image (fb:common.topic.image): Topic, Image
8. Key (fb:type.object.key): Object, Key
9. entry (fb:user.tsegaran.random.taxonomy_subject.entry): Taxonomy Subject, Taxonomy Entry
10. Teams (fb:sports.sports_team_location.teams): Sports Team Location, Sports Team

No other items found

[Assistant]
The property `fb:location.location.geolocation` seems to be the most relevant for finding the geographical location of Laos.

Now, I will construct a SPARQL query to retrieve the geolocation of Laos.

[Tool]
Got 1 row and 1 column:
| geolocation  |
| ------------ |
| fb:m.046vy25 |

[Assistant]
The geolocation of Laos is represented by the entity `fb:m.046vy25`. To provide a more meaningful answer, I will retrieve the label of this entity to understand its exact location on the world map.

Let's modify the SPARQL query to include the label of the geolocation entity.

[Tool]
Got 1 row and 2 columns:
| geolocation  | label |
| ------------ | ----- |
| fb:m.046vy25 |       |

[Assistant]
It appears that the geolocation entity `fb:m.046vy25` does not have a label associated with it in English. This suggests that we might need to look for another way to describe the location of Laos.

Since the direct geolocation label is not available, I will try to find the continent where Laos is located, which should give us a general idea of its position on the world map.

I will modify the SPARQL query to retrieve the continent of Laos.

[Tool]
Got 1 row and 2 columns:
| continent        | label     |
| ---------------- | --------- |
| Asia (fb:m.0j0k) | Asia (en) |

[Assistant]
Laos is located in Asia. While this does not provide the exact coordinates, it gives a clear indication of its general location on the world map.

I will now provide the final answer:

[User] what is the currency in italy?

[Assistant]
To answer the question about the currency in Italy, I first need to identify the entity representing Italy in Freebase and then find the property that links countries to their currencies.

Let's start by searching for the entity representing Italy.

[Tool]
Top 10 entity alternatives:
1. Italy, also known as Italia, Italian Republic (fb:m.03rjj): Italy, officially the Italian Republic, is a unitary parliamenta...uch as Leonardo da Vinci, Galileo, Michelangelo and Machiavelli., Country
2. Italy, also known as Ellis County / Italy town, Italy, Texas (fb:m.0100v5): Italy is a town in Ellis County, Texas, United States. As of the 2010 census, the town has a total population of 1,863., City/Town/Village
3. Italy, also known as Italy, New York (fb:m.0ycqz): Italy is a town located in Yates County, New York, United States...he southwestern part of the county and is south of Canandaigua ., City/Town/Village
4. Italy (fb:m.0fqgrp): The Italy Pavilion is a part of the World Showcase within Epcot ...ion is between the Germany and The American Adventure pavilions., Location
5. Italy (fb:m.0g21mhh): Musical Release

7. Italy (fb:m.0394f8_): Musical Release
8. Italy (fb:m.0_d_6gh): Musical Release
9. Italy (fb:m.0c846y0): Book Edition
10. Italy (fb:m.0c7jkdk): Book Edition

[Assistant]
The correct entity for Italy is `fb:m.03rjj` which represents the country Italy.

Next, I need to find the property that links countries to their currencies. I'll search for properties related to "currency" in Freebase.

[Tool]
Top 10 property alternatives:
1. Currency (fb:base.cars_refactor.msrp.currency): Currency, MSRP
2. Currency (fb:base.motorcycle.option_package.currency): Option package, Currency
3. Currency (fb:user.robert.earthquakes.qualified_money_value.currency): Qualified money value, Currency
4. Currency (fb:base.community.local_currency_area.currency): Local currency area, Local currency
5. Currency (fb:business.market_size.currency): Market size, Currency
6. Currency (fb:base.lightweight.regional_dated_money_value.currency): Regional Dated Money Value, Currency
7. Currency (fb:business.currency_sub_unit.currency): Currency sub-unit, Currency
8. Currency (fb:base.motorcycle.motorcycle_w_option_package_msrp.currency): Motorcycle w/ option package MSRP, Currency
9. Currency (fb:base.retail.retail_inventory_line.currency): Retail Inventory Line, Currency
10. Currency (fb:book.newspaper_price.currency): Newspaper price, Currency

[Assistant] The property `fb:business.currency_sub_unit.currency` seems to be related to currency, but it might not directly link countries to their currencies. Let's try to find the specific property that connects countries to their currencies by searching for properties of the Italy entity with a query related to "currency".

[Tool]
Top 10 property alternatives:
1. Currency Used (fb:location.country.currency_used): Currency, Country
2. Currency Formerly Used (fb:location.country.currency_formerly_used): Currency, Country
3. GDP (nominal) (fb:location.statistical_region.gdp_nominal): Statistical region, Dated Money Value
4. Inflation rate (fb:location.statistical_region.cpi_inflation_rate): Statistical region, Dated Percentage
5. GNI in PPP dollars (fb:location.statistical_region.gni_in_ppp_dollars): Statistical region, Dated Money Value
6. Flag (fb:symbols.flag_referent.flag): Flag referent, Flag use
7. GDP real (fb:location.statistical_region.gdp_real): Adjusted money value, Statistical region
8. Trade balance (% of GDP) (fb:location.statistical_region.trade_balance_as_percent_of_gdp): Statistical region, Dated Percentage
9. Deposit interest rate (fb:location.statistical_region.deposit_interest_rate): Statistical region, Dated Percentage
10. Continent (fb:base.locations.countries.continent): Continents, Countries

No other items found

[Assistant]
The property `fb:location.country.currency_used` seems to be the correct one to link countries to their currencies.

Now, I can construct a SPARQL query to find the currency used in Italy.

[Tool]
Failed to call function execute:
failed to parse input: parse error at position 122 for token EOF with content '' (the input most likely does not follow the grammar)

[Assistant]
It looks like there was a syntax error in the SPARQL query due to an incomplete statement. I will correct the query and re-execute it.

Here is the corrected SPARQL query:

```sparql
SELECT ?currency ?label
WHERE {
  fb:m.03rjj fb:location.country.currency_used ?currency .
  OPTIONAL { ?currency rdfs:label ?label }
}
```

Let's execute this query again to find the currency used in Italy.

[Tool]
Got 42 rows and 2 columns, showing the first 5 and last 5 rows below:
| currency          | label        |
| ----------------- | ------------ |
| Euro (fb:m.02l6h) | Eiro (lv)    |
| Euro (fb:m.02l6h) | Euras (lt)   |
| Euro (fb:m.02l6h) | Euro (ca)    |
| Euro (fb:m.02l6h) | Euro (cs)    |
| Euro (fb:m.02l6h) | Euro (da)    |

| Euro (fb:m.02l6h) | 유로 (ko)      |
| Euro (fb:m.02l6h) | ユーロ (ja)     |
| Euro (fb:m.02l6h) | 欧元 (zh)      |
| Euro (fb:m.02l6h) | 歐元 (zh-Hant) |

[Assistant]
The query returned multiple rows with different language labels for the currency used in Italy, but they all point to the same entity `Euro (fb:m.02l6h)`.

Therefore, the currency used in Italy is the Euro.

I will now provide the final answer.

[User] what is the national language of iran?

[Assistant]
To answer the question about the national language of Iran, I first need to identify the Freebase entities for "Iran" and "national language". Then, I will look for a property that connects countries with their official languages.

Let's start by searching for the entity representing Iran in Freebase.

[Tool]
Top 10 entity alternatives:
1. Iran, also known as Islamic Republic of Iran, Persia (fb:m.03shp): Iran, also known as Persia, officially the Islamic Republic of I... became the dominant cultural and political power in the region., Country

10. Iran (fb:m.0c5yq0t): Book Edition

[Assistant]
The correct entity for Iran is `fb:m.03shp` (Islamic Republic of Iran).

Next, I need to identify the property that represents the national language of a country. I'll search for properties related to "national language" or "official language".

[Tool]
Top 10 property alternatives:
1. Official Language (fb:location.country.official_language): Human Language, Country
2. Official Language(s) (fb:user.ktrueman.default_domain.international_organization.official_language_s): International Organization, Official Language
3. Language (fb:base.italiantv.foreign_language_adaptation.language): Foreign language adaptation, Human Language

10. Language (fb:base.cldrinfo.langinfo.language): cldr_language, langinfo

[Assistant]
The relevant property for the national language of a country seems to be `fb:location.country.official_language`.

Now, I will construct a SPARQL query to find the official language of Iran using the identified entity and property.

[Tool]
Failed to call function execute:
failed to parse input: parse error at position 126 for token EOF with content '' (the input most likely does not follow the grammar)

[Assistant]
It appears there was an issue with the SPARQL query syntax. Let me correct it and try again. Specifically, I will ensure the query is properly formatted and includes the necessary parts for retrieving the official language of Iran.

I will re-execute the corrected query.

[Tool]
Got 43 rows and 1 column, showing the first 5 and last 5 rows below:
| language                      |
| ----------------------------- |
| Persian Language (fb:m.032f6) |

| Persian Language (fb:m.032f6) |

[Assistant]
The query returned multiple rows, but they all point to the same entity for the national language of Iran, which is `Persian Language (fb:m.032f6)`.

Now, I can provide the final answer with the SPARQL query and the identified national language of Iran.

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.

[User] where was toussaint l'ouverture born?

[Assistant]
To answer the question about where Toussaint L'Ouverture was born, I'll first need to identify his Freebase entity. Then, I'll look for a property that indicates place of birth.

Let's start by searching for the entity of Toussaint L'Ouverture.

[Tool]
Top 10 entity alternatives:
1. Toussaint Louverture, also known as Toussaint Bréda, Toussaint L'Ouverture, François-Dominique Toussaint Louverture (fb:m.011wgw): François-Dominique Toussaint Louverture, also known as Toussaint... constitution for the colony, with himself as governor for life., Politician

8. Toussaint L'Ouverture (fb:m.02bfbj4)
9. Toussaint L'Ouverture (fb:m.011kgggh)
10. Toussaint L'Ouverture (fb:m.0mqm6cs)

[Assistant] The correct entity for Toussaint L'Ouverture is `fb:m.011wgw`. Next, I need to find the property that represents the place of birth. I will search for properties related to "birth place" for this entity.

[Tool]
Top 10 property alternatives:
1. Place of birth (fb:people.person.place_of_birth): Location, Person
2. Date of birth (fb:people.person.date_of_birth): Date/Time, Person
3. Country of nationality (fb:people.person.nationality): Country, Person
4. Date of death (fb:people.deceased_person.date_of_death): Deceased Person, Date/Time

9. Type (fb:type.object.type): Object, Type
10. Image (fb:common.topic.image): Topic, Image

No other items found

[Assistant]
The relevant property for the place of birth is `fb:people.person.place_of_birth`.

Now, I will construct a SPARQL query to find the place of birth for Toussaint L'Ouverture using the identified entity and property.

[Tool]
Got 1 row and 1 column:

[Assistant]
The SPARQL query returned the place of birth for Toussaint L'Ouverture as Saint-Domingue (`fb:m.01f5d8`).

I will now provide the final answer with the SPARQL query and the result.

[User] where did robin cook die?

[Assistant] To answer the question "Where did Robin Cook die?", I need to first identify the correct Robin Cook who the question might be referring to. There are likely multiple people named Robin Cook, so I'll start by searching for entities named "Robin Cook" in Freebase.

[Tool]
Top 10 entity alternatives:
1. Robin Cook, also known as Dr. Robin Cook (fb:m.02_5yp): Dr. Robert Brian "Robin" Cook is an American physician and novel...igest. His books have sold nearly 400 million copies worldwide ., Author

9. Bart Robinson Cook (fb:m.0gc2ynr): Film actor
10. Robin Cook Boxed Set (fb:m.06krdgm): Book

[Assistant]
From the search results, it seems like the question could be referring to either the American author Robin Cook (fb:m.02_5yp) or the British politician Robin Cook (fb:m.019jy5). Given the context of the question, it's more likely to be about the British politician Robin Cook (fb:m.019jy5), as authors typically don't have notable death locations associated with their names.

Next, I will search for properties related to death for this specific Robin Cook to find out where he died.

[Tool]
Top 10 property alternatives:
1. Cause of death (fb:people.deceased_person.cause_of_death): Deceased Person, Cause Of Death
2. Place of death (fb:people.deceased_person.place_of_death): Deceased Person, Location

No other items found

[Assistant]
Based on the search results, the property "Place of death" (fb:people.deceased_person.place_of_death) is relevant to finding out where Robin Cook died. Now, I will construct a SPARQL query to retrieve the place of death for Robin Cook (fb:m.019jy5).

Let's execute the query to find the place of death for Robin Cook.

[User] what movies is omar epps in?

[Assistant]
To answer the question "What movies is Omar Epps in?", I need to first identify the Freebase ID for Omar Epps. After finding his ID, I will look for the property that links actors to the movies they've acted in. Finally, I will construct a SPARQL query to retrieve the list of movies he has been in.

Let's start by searching for Omar Epps in Freebase.

10. Larry King, Omar Epps, Sheila Kelley (fb:m.06y1kf6): TV Episode

[Assistant] The correct entity for Omar Epps is `fb:m.02_tv5`. Now, I need to find the property that connects actors to the movies they've appeared in. I'll use the `search_property` function to find a suitable property.

[Assistant] It seems like the search returned many properties related to different types of performances. However, the property `fb:film.dubbing_performance.actor` seems to be the closest match for linking actors to their film roles. To confirm this, let's check some triples where this property is used to see if it indeed links actors to movies.

[Assistant]
The property `fb:film.dubbing_performance.actor` does not seem to be the correct one since it appears to link actors to their voice acting roles rather than their film appearances. Let's try another approach by searching for the property directly associated with film appearances.

I will now search for a property that links actors to the films they have appeared in.

9. Actor (fb:base.webvideo.internet_video_performance.actor): Internet Video Performance, Internet Video Actor
10. Actor (fb:cvg.game_performance.voice_actor): Video Game Performance, Video Game Actor

[Assistant]
None of these properties seem to be the correct one for linking actors to the films they have appeared in. Let's try a different approach by looking for a property that might be more specific to film appearances.

I will search for the property `starring` which is often used to denote an actor's role in a film.

[Tool]
Top 10 property alternatives:
1. Starring performances (fb:tv.special_tv_performance_type.starring_performances): Special TV performance type, TV Regular Performance

9. Actor (fb:tv.tv_guest_role.actor): TV episode performance, TV Actor
10. Actor (fb:base.tatort.tatort_team_membership.actor): Tatort Team Membership, TV Actor

[Assistant]
The property `fb:tv.special_tv_performance_type.starring_performances` and `fb:tv.tv_actor.starring_roles` seem to be related to starring roles in TV shows, not films. However, the property `fb:tv.regular_tv_appearance.actor` looks promising as it relates to actors in TV appearances, which might also apply to film appearances.

To confirm, I will check some triples where this property is used to see if it indeed links actors to their film roles.

[Assistant]
The property `fb:film.actor.film` seems to correctly link actors to the films they have appeared in. Now, I can construct a SPARQL query to retrieve the list of movies Omar Epps has been in.

Here is the SPARQL query:

```sparql
SELECT ?movie ?movieLabel
WHERE {
  VALUES (?actor) {(fb:m.02_tv5)}
  ?actor fb:film.actor.film ?movie .
  OPTIONAL { ?movie rdfs:label ?movieLabel }
}
```

This query will return the movies Omar Epps has been in along with their labels if available.

Let's execute this query to get the results.

[Tool]
Got 24 rows and 2 columns, showing the first 5 and last 5 rows below:

| fb:m.0k66h_  |            |
| fb:m.0k6ys4  |            |

[Assistant]
The SPARQL query returned the IDs of the movies Omar Epps has been in, but no labels were found for these movies. To provide a more informative response, I will modify the query to include the labels of the movies if they exist.

Here is the updated SPARQL query:

```sparql
SELECT ?movie ?movieLabel
WHERE {
  VALUES (?actor) {(fb:m.02_tv5)}
  ?actor fb:film.actor.film ?movie .
  OPTIONAL { ?movie rdfs:label ?movieLabel }
}
```

Let's execute this query again to get the results with movie labels if available.

[Tool]
Got 24 rows and 2 columns, showing the first 5 and last 5 rows below:
| movie        | movieLabel |

| fb:m.0k66h_  |            |
| fb:m.0k6ys4  |            |

[Assistant]
The SPARQL query still did not return any labels for the movies, indicating that the labels might not be available in the Freebase dataset. Therefore, I will provide the answer with just the movie IDs.

Here is the final SPARQL query:

```sparql
SELECT ?movie
WHERE {
  VALUES (?actor) {(fb:m.02_tv5)}
  ?actor fb:film.actor.film ?movie .
}
```

Let's execute this query to get the final results.

The SPARQL query successfully retrieved the movie IDs for the films Omar Epps has been in. Since the labels for these movies are not available in the Freebase dataset, I will provide the answer with just the movie IDs.

Here is the final SPARQL query:

```sparql
SELECT ?movie
WHERE {

  ?actor fb:film.actor.film ?movie .
}
```

The answer to the question "What movies is Omar Epps in?" is the list of movie IDs returned by the query.

Let's finalize the answer.

[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/

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.

[Assistant]
It appears that the names for the entities are not available directly through the `rdfs:label` property. I will try another approach to fetch the names by listing the triples associated with each entity and checking if there is a label or name property available.

First, let's check the triples for one of the entities to see if we can find a suitable property for the name.
