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 would play luke skywalker?

[Assistant]
Let's break down the question:

1. The question is asking about the actor who would play (or played) the character "Luke Skywalker".
2. I need to identify the entity for "Luke Skywalker" in Freebase.
3. Then, I need to find the property that links a fictional character to the actor who portrays them.

First, I'll search for the entity "Luke Skywalker" in Freebase.

[Tool]
Top 10 entity alternatives:
1. Luke Skywalker (fb:m.0f1bg): Luke Skywalker is a fictional character appearing as the central...e Awakens, which is planned to be released on December 18, 2015., has type Film character
2. Cordalis, also known as Luke Skywalker, Lucas Cordalis, Cordalis, Lucas, Cordalis Kiki, Cordalis Lucas (fb:m.01rb8py): has type Musical Artist

[Assistant]
The most relevant entity for the character "Luke Skywalker" is fb:m.0f1bg, which is described as a fictional character and central to the Star Wars saga.

Next, I need to find the property that links a fictional character to the actor who portrays them. I'll search for properties related to "actor" or "portrayed by" for this entity.

[Assistant]
The property "Portrayed in films" (fb:film.film_character.portrayed_in_films) seems most relevant, as it likely links the character to film performances, which should include the actor.

Now, I'll list some triples for Luke Skywalker (fb:m.0f1bg) with the property fb:film.film_character.portrayed_in_films to see the structure and what information is available.

[Tool]
Got 7 rows and 3 columns:
| subject                     | property                                                       | object        |

| Luke Skywalker (fb:m.0f1bg) | Portrayed in films (fb:film.film_character.portrayed_in_films) | fb:m.0k6jzc   |

[Assistant]
The property "Portrayed in films" links Luke Skywalker to several objects, which are likely film performance entities. To find the actor, I need to see what properties these film performance entities have—specifically, which property links them to the actor.

I'll list properties for one of these film performance entities, e.g., fb:m.010fs6tg.

[Tool]
Got 5 rows and 3 columns:
| subject       | property                                  | object                                      |
| ------------- | ----------------------------------------- | ------------------------------------------- |
| fb:m.010fs6tg | Type (fb:type.object.type)                | Film performance (fb:film.performance)      |
| fb:m.010fs6tg | Actor (fb:film.performance.actor)         | Mark Hamill (fb:m.0154d7)                   |
| fb:m.010fs6tg | Film (fb:film.performance.film)           | Star Wars: The Force Awakens (fb:m.0nb2r_p) |
| fb:m.010fs6tg | Character (fb:film.performance.character) | Luke Skywalker (fb:m.0f1bg)                 |
| fb:m.010fs6tg | rdf:type                                  | Film performance (fb:film.performance)      |

[Assistant]
The film performance entity (fb:m.010fs6tg) has the property "Actor" (fb:film.performance.actor), which links to Mark Hamill (fb:m.0154d7).

To answer the question, I need to write a SPARQL query that:
- Starts from Luke Skywalker (fb:m.0f1bg)
- Follows fb:film.film_character.portrayed_in_films to film performance entities
- Follows fb:film.performance.actor to the actor(s)
- Optionally retrieves the actor's label

I'll now construct the final SPARQL query.

[Assistant]
The most relevant property for "cause of death" for a real person is fb:people.deceased_person.cause_of_death.

Now, I will construct a SPARQL query to retrieve the cause of death for Bobby Darin (fb:m.0pj9t) using the property fb:people.deceased_person.cause_of_death. I will also try to get a label for the cause of death if available.

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:

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.

- Starring TV roles (fb:tv.tv_actor.starring_roles)
- TV regular appearances (fb:tv.tv_personality.tv_regular_appearances)
- TV episode performances (fb:tv.tv_actor.guest_roles)

To comprehensively answer the question, I should query all these properties to list the films and TV shows Kim Richards appeared in.

Despite identifying the correct entities and properties for the United States, World War II, and the presidency, the Freebase data appears to be incomplete or missing for the relevant time period (1939-1945). All attempts to retrieve the president(s) of the United States during WWII using date filters or direct entity lookups for Franklin D. Roosevelt and Harry S. Truman returned no results. Therefore, it is not possible to construct a satisfactory SPARQL query to answer the question with the available data.

[User] who was the leader of the us during wwii?

[Assistant]
Let's break down the question:

1. The user is asking for the leader of the United States during World War II.
2. We need to identify:
   - The entity for "United States"
   - The entity for "World War II"
   - The property that links a country to its leader during a specific time period (likely "head of state", "president", or similar, with a time constraint).

First, let's search for the entity for "United States".

[Assistant]
The most relevant entity for "United States" as a country is fb:m.09c7w0.

Next, let's search for the entity for "World War II".

Top 10 entity alternatives:
1. World War II, also known as The Second World War, WWII, WW2, World War 2, World War, 1939-1945 (fb:m.081pw): World War II, also known as the Second World War, was a global w...declarations of war on Germany by France and the United Kingdom., has type Military Conflict

[Assistant]
The most relevant entity for "World War II" as a military conflict is fb:m.081pw.

Now, we need to find the property that links a country to its leader during a specific time period. Likely candidates are "president", "head of state", or "leader". Let's search for properties related to "leader" for the United States entity.

No other items found

[Assistant]
The property "President" (fb:user.exooo.default_domain.head_of_state.president) seems most relevant for linking the United States to its leader.

Now, we need to find the president of the United States during World War II. Since World War II lasted from 1939 to 1945, we need to find the president(s) whose tenure overlapped with this period.

Let's check what properties are available for the "President" property, such as tenure start and end dates, to filter by the relevant time period.

[Tool]
Got 3 rows and 3 columns:
| subject                                | property                                                         | object       |

| United States of America (fb:m.09c7w0) | President (fb:user.exooo.default_domain.head_of_state.president) | fb:m.03wzcr3 |

[Assistant]
There are three presidents listed for the United States in Freebase:

- fb:m.03wzcqr
- fb:m.03wzcqy
- fb:m.03wzcr3

To determine which of these were president during World War II (1939-1945), we need to find their names and their tenure dates. Let's look up the properties for one of these president entities to see what information is available. I'll start with fb:m.03wzcqr.

[Tool]
Got 4 rows and 3 columns:
| subject      | property                                  | object                                            |
| ------------ | ----------------------------------------- | ------------------------------------------------- |
| fb:m.03wzcqr | Type (fb:type.object.type)                | Employment tenure (fb:business.employment_tenure) |
| fb:m.03wzcqr | From (fb:business.employment_tenure.from) | 1789-04-30 (xsd:date)                             |
| fb:m.03wzcqr | To (fb:business.employment_tenure.to)     | 1797-03-04 (xsd:date)                             |
| fb:m.03wzcqr | rdf:type                                  | Employment tenure (fb:business.employment_tenure) |

The entity fb:m.03wzcqr represents an employment tenure from 1789-04-30 to 1797-03-04, which is not during World War II. This suggests that the "President" property links to employment tenure entities, not directly to people.

We need to find the actual person who held the presidency during the relevant period. Let's check the properties of the employment tenure entity to see if it links to a person.

The employment tenure entity does not directly show a link to a person in the listed properties. However, in Freebase, employment tenure entities typically have a property like "employee" or "person" that links to the actual person.

Let's search for properties of the employment tenure entity fb:m.03wzcqr related to "person" or "employee".

[Assistant]
It appears that the employment tenure entity does not directly link to a person via the properties we've checked, but the property "Employment history" (fb:people.person.employment_history) links from a person to their employment tenure.

Given this, we can reverse the approach:
- Find all employment tenure entities for the U.S. presidency,
- Filter those whose tenure overlaps with 1939-1945,
- Then find the person who has that employment tenure in their employment history.

Let's write a SPARQL query to:
1. Get all employment tenures for the U.S. presidency,
2. Filter for those overlapping with 1939-09-01 to 1945-09-02 (WWII),
3. Get the person who has that employment tenure in their employment history,
4. Optionally, get their label.

Let's proceed with this query.

[Tool] Got no rows and 5 columns

[Assistant]
The query returned no results, which suggests that the date properties or the linkage between employment tenure and person may be different than expected, or the data may be incomplete.

To troubleshoot, let's first check what properties are available for the other two employment tenure entities (fb:m.03wzcqy and fb:m.03wzcr3) to see if they have different or additional properties.

[Assistant]
Now we see that the property fb:business.employment_tenure.person links the employment tenure to the person. This was missing from the first entity, but present in these two.

Let's revise our query to use this property to get the president during WWII. We'll:
- Get all employment tenures for the U.S. presidency,
- Filter for those overlapping with WWII,
- Get the person via fb:business.employment_tenure.person,
- Optionally, get their label.

Let's try this improved query.

[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#

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#
gn: <http://www.geonames.org/ontology#
bd: <http://www.bigdata.com/rdf#
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] where was terry waite born?

[Assistant]
Let's break down the question:

1. The entity in question is "Terry Waite".
2. The property we are interested in is "place of birth".

First, I will search for the entity "Terry Waite" in Freebase to find the correct IRI.

[Tool]
Top 10 entity alternatives:
1. Terry Waite (fb:m.013p_j): Terence Hardy "Terry" Waite, CBE is an English humanitarian and ... president of Emmaus UK, a charity for formerly homeless people., has type Author
2. Terry Waites (fb:m.05mrb5n): Terry Waites was an Australian rules footballer who played for C...lingwood's 1953 premiership team, in just his seventh VFL match., has type Athlete
3. Terry Waite Sez (fb:m.0n0ddq): has type Musical Recording
4. Terry Waite Sez (fb:m.0sgyp7): has type Musical Recording
5. Terry Waite Sez (fb:m.011740ty): has type Composition
6. Terry Waites (fb:m.0_6plwk): has type Musical Artist
7. Terry Waite Sez (fb:m.0mq49x1)
8. Terry Waite Sez (fb:m.0ltscgx)
9. Terry Waite Sez (fb:m.0lbq3dk)
10. Terry Waite April 1993 (fb:m.02b_7_h)

[Assistant]
The most relevant entity for "Terry Waite" is fb:m.013p_j, who is an English humanitarian and author.

Next, I need to find the property in Freebase that corresponds to "place of birth" for this entity.

[Tool]
Top 10 property alternatives:
1. Place of birth (fb:people.person.place_of_birth): links to type Location, part of Person schema
2. Date of birth (fb:people.person.date_of_birth): links to type Date/Time, part of Person schema
3. Gender (fb:people.person.gender): part of Person schema, links to type Gender
4. Country of nationality (fb:people.person.nationality): part of Person schema, links to type Country
5. Religion (fb:people.person.religion): links to type Religion, part of Person schema
6. Name (fb:type.object.name): part of Object schema, links to type Text
7. Type (fb:type.object.type): part of Object schema, links to type Type
8. Key (fb:type.object.key): part of Object schema, links to type Key
9. Image (fb:common.topic.image): part of Topic schema, links to type Image
10. Article (fb:common.topic.article): links to type Document, part of Topic schema

No other items found

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

Now, I will construct a SPARQL query to find the place of birth for Terry Waite (fb:m.013p_j) using this property. I will also try to retrieve the label of the place for better readability.

[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:

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 type of art leonardo da vinci do?

[Assistant]
Let's break down the question:

1. The user wants to know the types of art Leonardo da Vinci created.
2. We need to identify the entity for "Leonardo da Vinci" in Freebase.
3. Then, we need to find properties related to the types or genres of art he was involved in.

First, I'll search for the entity "Leonardo da Vinci" in Freebase.

The property "Art Forms" (fb:visual_art.visual_artist.art_forms) seems to directly relate to the types of art Leonardo da Vinci practiced.

Now, I'll construct a SPARQL query to retrieve the art forms associated with Leonardo da Vinci (fb:m.04lg6) using this property. I'll also try to get the labels for the art forms for better readability.
