[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 http://galera:7002

You can use the following SPARQL prefixes implicitly in all functions:

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 voices does seth macfarlane play on family guy?

[Assistant]
Let's break down the question:

1. We need to identify the entity for "Seth MacFarlane".
2. We need to identify the entity for "Family Guy".
3. We need to find the property that links a person to the characters they voice (voice acting roles).
4. We need to filter for roles specifically in "Family Guy".

Let's start by searching for "Seth MacFarlane" in Freebase.

[Assistant]
The main "Family Guy" TV program entity is fb:m.019nnl.

Now, we need to find the property that links a person (Seth MacFarlane) to the characters they voice, specifically in the context of a TV program (Family Guy). Let's search for properties related to "voice" for Seth MacFarlane.

[Assistant] It appears that searching for "voice" properties directly on Seth MacFarlane did not yield a relevant property. Let's try searching for properties related to "voice actor" or "character voiced" more generally in Freebase.

[Assistant]
The property "Voice actor" (fb:base.animemanga.sound_drama_performance.voice_actor) seems relevant, but it is part of a specific schema for sound drama performance. The other properties are related to dubbing performances.

Let's try searching for properties related to "character voiced" or "character" to see if there is a more general property for linking a person to a character they voice.

The search for "character voiced" did not yield a general property for linking a person to a character they voice, except for the "Voice actor" property in a specific schema.

The objects linked from "Family Guy" via "regular_cast" are likely instances of "TV Regular Performance". These should contain information about the actor and the character they play.

It appears that the "TV Regular Performance" entity does not directly link to the character name via a property called "character". However, there may be another property or perhaps a different approach is needed.

Let's try listing all properties for one of these "TV Regular Performance" entities (e.g., fb:m.02kk65p) to see if any property links to the character.

[Assistant]
We have found that the property "Character" (fb:tv.regular_tv_appearance.character) links the TV Regular Performance to the character, and "Actor" (fb:tv.regular_tv_appearance.actor) links to the actor.

Now, we can construct a SPARQL query to find all characters (voices) that Seth MacFarlane (fb:m.021yw7) plays on Family Guy (fb:m.019nnl), using the "TV Regular Performance" entities.

Let's write the query to retrieve all characters where:
- The series is Family Guy
- The actor is Seth MacFarlane
- The special performance type is "Voice"
- We return the character IRIs and optionally their labels

Here is the SPARQL query:

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.

I found several books written by Charles Darwin. The most famous one, often referred to as "the book Charles Darwin wrote," is "On the Origin of Species by Means of Natural Selection" (fb:m.0c1t1n1).

To answer the question fully, I will retrieve the title of this book using its entity.

[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 http://galera:7002

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.

The events data for Hollywood, CA in Freebase is outdated, with the most recent events listed from 2014 and earlier. There are no current or upcoming events available in the knowledge graph for "this weekend."

Here is the SPARQL query I used, which retrieves all events in Hollywood, their labels, and their start and end dates:

```sparql
SELECT ?event ?eventLabel ?startDate ?endDate WHERE {
  fb:m.0f2wj fb:location.location.events ?event .
  OPTIONAL { ?event rdfs:label ?eventLabel . }
  OPTIONAL { ?event fb:time.event.start_date ?startDate . }
  OPTIONAL { ?event fb:time.event.end_date ?endDate . }
} ORDER BY DESC(?startDate)
```

**Answer:**
Unfortunately, Freebase does not contain up-to-date information about events or things to do in Hollywood, CA for this weekend. The latest events in the database are from 2014 and earlier. For current events, you may want to consult local event listings or tourism websites.

If you would like to see the historical events data from Freebase, let me know!

[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 http://galera:7002

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#

xsd: <http://www.w3.org/2001/XMLSchema#
foaf: <http://xmlns.com/foaf/0.1/
skos: <http://www.w3.org/2004/02/skos/core#
dct: <http://purl.org/dc/terms/
dc: <http://purl.org/dc/elements/1.1/
prov: <http://www.w3.org/ns/prov#
schema: <http://schema.org/
geo: <http://www.opengis.net/ont/geosparql#
geosparql: <http://www.opengis.net/ont/geosparql#

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.

There are several events linked to Hollywood, such as film festivals and award shows. However, these events seem to be from previous years (e.g., 2013, 2014). To answer the user's question about "this weekend," I need to check if these events have date properties and filter for upcoming or current events.

Next, I'll search for properties related to the date or time of these events. I'll use one of the event entities, such as "2014 HollyShorts Film Festival" (fb:m.010c4f41), to search for date-related properties.

There are properties for "Start date" (fb:time.event.start_date) and "End date" (fb:time.event.end_date) for events. This will allow us to filter events in Hollywood by their dates.

To answer the user's question about "this weekend," I need to:
- Get all events in Hollywood.
- Retrieve their start and end dates.
- Filter for events whose dates overlap with this weekend.

Since I don't know the exact current date, I'll write a SPARQL query that retrieves all events in Hollywood with their start and end dates. The user can then see which ones are upcoming or happening this weekend.

I'll include optional labels for the events.

Here is the SPARQL query I used, which retrieves all events in Hollywood, their labels, and their start and end dates:

```sparql
SELECT ?event ?eventLabel ?startDate ?endDate WHERE {
  fb:m.0f2wj fb:location.location.events ?event .
  OPTIONAL { ?event rdfs:label ?eventLabel . }
  OPTIONAL { ?event fb:time.event.start_date ?startDate . }
  OPTIONAL { ?event fb:time.event.end_date ?endDate . }
} ORDER BY DESC(?startDate)
```

**Answer:**
Unfortunately, Freebase does not contain up-to-date information about events or things to do in Hollywood, CA for this weekend. The latest events in the database are from 2014 and earlier. For current events, you may want to consult local event listings or tourism websites.

[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 http://galera:7002

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 do people speak in uk?

[Assistant]
Let's break down the question:

1. The user wants to know what languages are spoken in the UK.
2. We need to identify the entity for "UK" (United Kingdom) in Freebase.
3. Then, we need to find the property that links a country to the languages spoken there.
4. Finally, we'll construct a SPARQL query to retrieve the languages spoken in the UK.

First, let's search for the entity "UK" or "United Kingdom" in Freebase.

[Tool]
Top 10 entity alternatives:
1. United Kingdom, also known as United Kingdom of Great Britain and Northern Ireland, United Kingdom of Great Britain and Ireland, United Kingdom of Great Britain, UK, U.K. (fb:m.07ssc): The United Kingdom of Great Britain and Northern Ireland, common...urth-largest in Europe and second-largest in the European Union., has type Country
2. United Kingdom (fb:m.0g9jnqz)
3. United Kingdom (fb:m.0gb3qxf)
4. United Kingdom (fb:m.0nfkbl): has type Musical Recording
5. United Kingdom (fb:m.0fr7h8): The United Kingdom pavilion is part of the World Showcase within...lorida. Its location is between the France and Canada pavilions., has type Location
6. United Kingdom (fb:m.036hlfh): has type Musical Release
7. United Kingdom (fb:m.02842y0): United Kingdom is the fourth album by American Music Club. It wa...rk Eitzel has composed about his long-term muse, Kathleen Burns., has type Musical Album
8. United Kingdom (fb:m.0wh7br): has type Musical Recording
9. UK, also known as United Kingdom (fb:m.0g0d_ms): Steve and the Deadly 60 team are on their home turf, the UK. The...iant web to demonstrate just what lethal killers spiders can be., has type TV Episode
10. United Kingdom (fb:m.079l6c5): Two men on a local council fight the system when forced with massive spending cuts., has type TV Episode

[Assistant]
The most relevant entity for the United Kingdom (UK) as a country is fb:m.07ssc.

Next, we need to find the property that links a country to the languages spoken there. Let's search for properties related to "language" for this entity.

[Tool]
Top 10 property alternatives:
1. Languages spoken (fb:location.country.languages_spoken): links to type Human Language, part of Country schema
2. Official Language (fb:location.country.official_language): links to type Human Language, part of Country schema
3. Type (fb:base.biblioness.bibs_location.loc_type): part of Bibs Location schema, links to type Text
4. Type (fb:type.object.type): part of Object schema, links to type Type
5. Subjects (fb:common.topic.subjects): part of Topic schema, links to type Topic
6. Titles (fb:media_common.netflix_genre.titles): part of Netflix Genre schema, links to type Netflix Title
7. Adjectival form (fb:location.location.adjectival_form): part of Location schema, links to type Text
8. Adjectival form (fb:freebase.linguistic_hint.adjectival_form): part of Linguistic hint schema, links to type Text
9. Adjectival form (fb:base.aareas.schema.administrative_area.adjectival_form): part of Administrative Area schema, links to type Text
10. Flag (fb:symbols.flag_referent.flag): part of Flag referent schema, links to type Flag use

No other items found

[Assistant]
The most relevant properties are:
- fb:location.country.languages_spoken (Languages spoken)
- fb:location.country.official_language (Official Language)

Since the user asked what people speak in the UK, not just the official language, we should use "languages spoken".

Now, let's construct a SPARQL query to get the languages spoken in the UK (fb:m.07ssc) using the property fb:location.country.languages_spoken. We will also try to get the labels of the languages.

Here's the query I'll use:
