Failed to generate SPARQL 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 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#

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 properties related to voicing characters are not directly listed. However, we can try searching for the property that links a person to the characters they voice in general. Let's search for a property like "voice actor" or "voiced by" in the Freebase knowledge graph.

[Assistant] The property "Voice actor" (fb:base.animemanga.sound_drama_performance.voice_actor) seems to be the closest match. However, it is specific to anime and manga. Since we are looking for characters in Family Guy, let's try another search for a more general property like "voiced by" or "voice role".

[Assistant] The property "Played by" (fb:base.saturdaynightlive.snl_character.played_by) seems to be the closest match for linking a character to the actor who voices them. However, it is specific to Saturday Night Live. Let's try another search for a more general property like "voice role" or "character voiced by".

[Assistant]
None of the properties listed seem to directly match what we are looking for. However, the property "Voice actor" (fb:base.animemanga.sound_drama_performance.voice_actor) might still be useful, even though it is specific to anime and manga. We can try using it and see if it returns any relevant results for Seth MacFarlane's voice roles in Family Guy.

Let's execute a SPARQL query to find the characters Seth MacFarlane voices in Family Guy using the "Voice actor" property.

[Assistant]
The query did not return any results, which suggests that the "Voice actor" property might not be the right one for this context. Let's try a different approach by searching for the characters in Family Guy and then checking if Seth MacFarlane is listed as their voice actor.

None of the properties listed seem to directly match what we are looking for. However, let's try the "Role" property (fb:base.webvideo.internet_video_series_crew_gig.role) to see if it might work for linking characters to their voice actors in Family Guy.

Let's execute a SPARQL query to find the voice actor for Peter Griffin using the "Role" property.

[Assistant]
The query using the "Role" property also did not return any results. This suggests that the property might not be the correct one for linking characters to their voice actors in Family Guy.

Given that we are not finding the correct property, let's try a different approach by searching for the characters and then manually checking if Seth MacFarlane is listed as their voice actor.

### Manual Check for Seth MacFarlane's Voice Roles

Let's search for Seth MacFarlane and see if there are any properties that link him to the characters he voices in Family Guy.

We will use the entity for Seth MacFarlane (fb:m.021yw7) and list the triples where he is the subject to see if there are any properties that indicate the characters he voices.

The query using the "Starring TV roles" property returned several results, but these are not directly the characters Seth MacFarlane voices. These results are likely the TV roles he has played, which may include both voice and live-action roles.

To narrow down the results to the characters he voices in Family Guy, we need to filter the results to only include characters from Family Guy. Let's try to find the entity for Family Guy and then filter the results accordingly.

None of the properties listed seem to directly match what we are looking for. However, let's try the "Voice actor" property (fb:base.animemanga.sound_drama_performance.voice_actor) one more time to see if it might work for linking characters to their voice actors in Family Guy.

Let's execute a SPARQL query to find the voice actor for Peter Griffin using the "Voice actor" property again, but this time with a broader search to include any related properties.

[Tool] Got no rows and 1 columns

[Assistant]
The query using the "Voice actor" property and a broader search still did not return any results. This suggests that the property might not be the correct one for linking characters to their voice actors in Family Guy.

Given that we are not finding the correct property, let's try a different approach by manually checking the characters and their voice actors using the information available in the knowledge graph.

### Manual Check for Specific Characters

Let's manually check the characters Peter Griffin, Stewie Griffin, and Brian Griffin to see if Seth MacFarlane is listed as their voice actor.

### List Triples for Stewie Griffin

Let's list the triples for Stewie Griffin to see if there is any information about his voice actor.

[Assistant]
The query did not return any results for Stewie Griffin either, which suggests that the property `fb:tv.tv_character.voice_actor` might not be the correct one for linking characters to their voice actors in Family Guy.

### Manual Check for Brian Griffin

Let's try the same approach for Brian Griffin.

### List Triples for Brian Griffin

Let's list the triples for Brian Griffin to see if there is any information about his voice actor.

[Assistant]
The query did not return any results for Brian Griffin either, which suggests that the property `fb:tv.tv_character.voice_actor` might not be the correct one for linking characters to their voice actors in Family Guy.

[Assistant]
The list of triples for Seth MacFarlane shows several roles he has played, but it does not directly indicate the characters he voices in Family Guy. However, we can try to filter these roles to see if they are characters from Family Guy.

Let's filter the results to only include characters from Family Guy by checking if these roles are associated with the Family Guy TV program (fb:m.019nnl).

### Filter Roles to Include Only Family Guy Characters

Let's execute a SPARQL query to filter the roles to only include characters from Family Guy.

[Tool] Got no rows and 1 columns

[Assistant]
The query did not return any results, which suggests that the "Starring TV roles" property might not be the correct one for linking Seth MacFarlane to the characters he voices in Family Guy.

Given that we are not finding the correct property, and the Freebase knowledge graph does not seem to have the specific information we need, we may need to conclude that the information is not available in the current form in the Freebase knowledge graph.

### Conclusion

Based on the available data in the Freebase knowledge graph, we are unable to find a direct property that links Seth MacFarlane to the characters he voices in Family Guy. Therefore, we cannot provide a definitive answer using the current SPARQL queries.

However, it is widely known that Seth MacFarlane voices several characters in Family Guy, including Peter Griffin, Stewie Griffin, and Brian Griffin. If you need this information for a specific purpose, you might want to refer to external sources or official Family Guy documentation.

### Best Attempt

Here is the best attempt at a SPARQL query to find the characters Seth MacFarlane voices in Family Guy, although it did not return any results:

```sparql
SELECT ?character WHERE {
  fb:m.021yw7 fb:tv.tv_actor.starring_roles ?character .
  ?character fb:tv.tv_program_character.program fb:m.019nnl
}
```

Feedback (status=retry):
The current SPARQL query is not returning any results because the property `fb:tv.tv_actor.starring_roles` might not be the right one to link Seth MacFarlane to the characters he voices in Family Guy. We should try using a different property or approach. One possible alternative is to look for a property that directly links a person to the characters they voice in a show.

You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:
freebase at https://qlever.cs.uni-freiburg.de/api/freebase

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

The search for the character "Edward Scissorhands" in the movie `fb:m.01s3vk` returned multiple results, but the most relevant one is `fb:m.01s3vk` itself, which is the movie. This suggests that the character "Edward Scissorhands" might be directly linked to the movie rather than being a separate entity.

Let's try to find the actor who played the character "Edward Scissorhands" in the movie `fb:m.01s3vk` by using the property `fb:film.performance.character` and then linking it to the actor.

We will use the property `fb:film.performance.character` to find the character and then link it to the actor using `fb:film.performance.actor`.

SELECT ?actor
WHERE {
  fb:m.01s3vk fb:film.performance.character ?character .
  ?character rdfs:label "Edward Scissorhands"@en .
  ?performance fb:film.performance.character ?character .
  ?performance fb:film.performance.actor ?actor .
}
```

Let's execute this query to find the actor who played Edward Scissorhands.

[Tool] Got no rows and 1 columns

[Assistant]
The query did not return any results, which suggests that the properties `fb:film.performance.character` and `fb:film.performance.actor` might not be the correct ones to use for this specific case. Let's try a different approach by directly linking the movie to the actor who played the main character.

We can use the property `fb:film.film.starring` to find the main cast of the movie and then filter by the character "Edward Scissorhands".

Here is the SPARQL query:

```sparql
SELECT ?actor
WHERE {
  fb:m.01s3vk fb:film.film.starring ?starring .
  ?starring fb:film.performance.character ?character .
  ?starring fb:film.performance.actor ?actor .
  ?character rdfs:label "Edward Scissorhands"@en .
}
```

Let's execute this query to find the actor who played Edward Scissorhands.

[Tool]
Got 1 row and 1 column:
| actor                    |
| ------------------------ |
| Johnny Depp (fb:m.0jfx1) |

[Assistant]
The query successfully returned the actor who played Edward Scissorhands in the movie "Edward Scissorhands". The actor is Johnny Depp, with the IRI `fb:m.0jfx1`.

Therefore, the answer to the question "Who plays Edward Scissorhands?" is Johnny Depp.

Here is the final SPARQL query and answer:

```sparql
SELECT ?actor
WHERE {
  fb:m.01s3vk fb:film.film.starring ?starring .
  ?starring fb:film.performance.character ?character .

The query returned a list of books authored by Charles Darwin, including their labels in different languages. One of the most famous books by Charles Darwin is "On the Origin of Species," which is not explicitly listed in the results. However, it is likely included under a different title or variant.

To ensure we capture all relevant books, let's refine the query to filter out duplicates and focus on the most well-known works. We can also add a limit to the number of results to make the output more manageable.

Here is the refined SPARQL query:

```sparql
SELECT DISTINCT ?book ?bookLabel
WHERE {

[Assistant]
The refined query has returned a list of books authored by Charles Darwin, including multiple translations of "The Voyage of the Beagle." However, "On the Origin of Species" is still not explicitly listed. Given that "On the Origin of Species" is one of Charles Darwin's most famous works, it is likely included in the results but under a different title or variant.

To ensure we capture "On the Origin of Species," let's search for the specific book by its title. We can use the `search_entity` function to find the entity for "On the Origin of Species."

[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/

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 did george orwell died of?

[Assistant] To answer the question about what George Orwell died of, we need to identify the entity for George Orwell and then find the property that indicates the cause of death. Let's start by searching for George Orwell in the Freebase knowledge graph.

[Tool]
Top 10 entity alternatives:
1. George Orwell, also known as Eric Arthur Blair (fb:m.034bs): Eric Arthur Blair, who used the pen name George Orwell, was an E...ht Police, Room 101, Memory hole, doublethink, and thoughtcrime., Eric Arthur Blair (25 June 1903 21 January 1950), better known b...in language.His two most popular works are 1984 and Animal Farm., Author
2. George Orwell (fb:m.0b3mv01): Book Edition
3. George Orwell (fb:m.0c5xtp5): Book Edition
4. George Orwell (fb:m.08n0rk7): Book Edition
5. George Orwell (fb:m.04vtrvn): Book Edition
6. George Orwell (fb:m.04t4gy2): Book
7. George Orwell (fb:m.0c6n17d): Book Edition
8. George Orwell (fb:m.04txhhn): Book Edition
9. George Orwell (fb:m.079p0vc): Book Edition
10. George Orwell (fb:m.079p0vv): Book Edition

[Assistant] The top result for George Orwell is `fb:m.034bs`, which seems to be the correct entity for the author Eric Arthur Blair, better known as George Orwell. Next, we need to find the property that indicates the cause of death. Let's search for properties related to "cause of death" for this entity.

[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
3. Date of death (fb:people.deceased_person.date_of_death): Deceased Person, Date/Time
4. Country of nationality (fb:people.person.nationality): Country, Person
5. Date of birth (fb:people.person.date_of_birth): Date/Time, Person
6. Religion (fb:people.person.religion): Religion, Person
7. Place of birth (fb:people.person.place_of_birth): Location, Person
8. Gender (fb:people.person.gender): Person, Gender
9. Name (fb:type.object.name): Object, Text
10. Type (fb:type.object.type): Object, Type

No other items found

[Assistant]
The property `fb:people.deceased_person.cause_of_death` seems to be the correct one for the cause of death. Now, let's construct a SPARQL query to retrieve the cause of death for George Orwell (`fb:m.034bs`).

Here is the initial SPARQL query:

```sparql
SELECT ?causeOfDeath
WHERE {
  fb:m.034bs fb:people.deceased_person.cause_of_death ?causeOfDeath .
}
```

Let's execute this query to see the result.

[Tool]
Got 1 row and 1 column:
| causeOfDeath              |
| ------------------------- |
| Tuberculosis (fb:m.07jwr) |

[Assistant]
The SPARQL query returned that George Orwell died of tuberculosis. To provide a more complete answer, we can include the label of the cause of death in the query. However, since the label is optional, we will use an `OPTIONAL` clause to fetch it.

Here is the refined SPARQL query:

```sparql
SELECT ?causeOfDeath ?causeOfDeathLabel
WHERE {
  fb:m.034bs fb:people.deceased_person.cause_of_death ?causeOfDeath .
  OPTIONAL { ?causeOfDeath rdfs:label ?causeOfDeathLabel . }
}
```

Let's execute this query to get the label as well.

[Tool]
Got 42 rows and 2 columns, showing the first 5 and last 5 rows below:
| causeOfDeath              | causeOfDeathLabel |
| ------------------------- | ----------------- |
| Tuberculosis (fb:m.07jwr) | Batuk kering (ms) |
| Tuberculosis (fb:m.07jwr) | Gruźlica (pl)     |
| Tuberculosis (fb:m.07jwr) | Gümőkór (hu)      |
| Tuberculosis (fb:m.07jwr) | Lao (vi)          |
| Tuberculosis (fb:m.07jwr) | Sušica (hr)       |
| ...                       | ...               |
| Tuberculosis (fb:m.07jwr) | วัณโรค (th)       |
| Tuberculosis (fb:m.07jwr) | 결핵 (ko)           |
| Tuberculosis (fb:m.07jwr) | 結核 (ja)           |
| Tuberculosis (fb:m.07jwr) | 結核 (zh-Hant)      |
| Tuberculosis (fb:m.07jwr) | 结核 (zh)           |

[Assistant]
The query returned multiple labels for the cause of death in different languages. The most common and recognizable label is "Tuberculosis" in English. Since the user is likely interested in the English label, we can filter the results to only show the English label.

Here is the final SPARQL query:

```sparql
SELECT ?causeOfDeath ?causeOfDeathLabel
WHERE {
  fb:m.034bs fb:people.deceased_person.cause_of_death ?causeOfDeath .
  OPTIONAL { ?causeOfDeath rdfs:label ?causeOfDeathLabel . FILTER(LANG(?causeOfDeathLabel) = "en") }
}
```

Let's execute this query to get the English label.

[Tool]
Got 1 row and 2 columns:
| causeOfDeath              | causeOfDeathLabel |
| ------------------------- | ----------------- |
| Tuberculosis (fb:m.07jwr) | Tuberculosis (en) |

[Assistant]
The final SPARQL query has successfully retrieved the cause of death for George Orwell, which is "Tuberculosis" in English.

Here is the final SPARQL query and the answer to the user's question:

```sparql
SELECT ?causeOfDeath ?causeOfDeathLabel
WHERE {
  fb:m.034bs fb:people.deceased_person.cause_of_death ?causeOfDeath .
  OPTIONAL { ?causeOfDeath rdfs:label ?causeOfDeathLabel . FILTER(LANG(?causeOfDeathLabel) = "en") }
}
```

Answer: George Orwell died of Tuberculosis.

Now, I will provide the final answer using the `answer` function.
