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:

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] Count the number of musical work which were sold by Sony Music?

[Assistant]
Let's break down the question:

1. We need to identify the entity for "Sony Music" in DBpedia.
2. We need to find the class or type for "musical work" in DBpedia.
3. We need to find the property that links a musical work to the company that sold it (likely something like "soldBy", "publisher", "label", or "distributor").
4. We need to count the number of such musical works where the seller is Sony Music.

First, I will search for the entity "Sony Music" in DBpedia.

10. Sony Music Philippines (dbr:Sony_Music_Philippines)

[Assistant]
The main entity for "Sony Music" in DBpedia is dbr:Sony_Music.

Next, I will search for the class or type representing "musical work" in DBpedia.

[Tool]
Top 10 entity alternatives:
1. Musical work (dbr:Musical_work)
2. musical work (dbo:MusicalWork)
3. Working (musical) (<http://dbpedia.org/resource/Working_(musical)>): Working is a musical with a book by Stephen Schwartz and Nina Fa...s interviews with people from different regions and occupations.

10. Tchaikovsky's musical works (<http://dbpedia.org/resource/Tchaikovsky's_musical_works>)

[Assistant]
The class for "musical work" in DBpedia is dbo:MusicalWork.

Now, I need to find the property that links a musical work to the company that sold, published, or distributed it. Likely candidates are "publisher", "label", or "distributor". I will search for properties related to "sold by" or "label" for dbo:MusicalWork.

Feedback (status=retry):
The SPARQL query is incorrect. It uses '?work dbp:label dbr:Sony_Music', which is not the correct way to represent 'sold by Sony Music'. The 'dbp:label' property is for the human-readable label, not for indicating a relationship such as 'sold by'. The query should look for musical works (dbo:MusicalWork) that have a property indicating they were sold by Sony Music (dbr:Sony_Music). Common properties for this relationship could be 'dbo:seller', 'dbo:distributor', or similar. Please review the ontology and use the appropriate property to represent 'sold by'. Additionally, ensure the query returns the correct count based on the right relationship.

[Assistant]
Thank you for the feedback. You are correct: dbp:label is not the appropriate property for "sold by". Instead, we should look for properties like dbo:seller, dbo:distributor, or similar that represent the relationship of a musical work being sold by Sony Music.

Step-by-step, I will:
1. Search for properties related to "seller" or "distributor" in the DBpedia ontology.
2. Check which of these properties are used with dbo:MusicalWork.
3. Construct a query using the correct property.

Let's start by searching for properties related to "seller".

Feedback (status=done):
The SPARQL query correctly counts the number of distinct musical works (dbo:MusicalWork) that have Sony Music (dbr:Sony_Music) as their record label using the dbo:recordLabel property. The query uses the correct entity types and properties, and the answer is consistent with the query result. No further refinement is needed.

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 the headquarters of Sigma TV

[Assistant]
Let's break down the question:

1. The entity in question is "Sigma TV".
2. The property we are interested in is the "headquarters" location.

First, I will search for the entity "Sigma TV" in DBpedia to find its IRI.

[Tool]
Top 10 entity alternatives:
1. Sigma TV (dbr:Sigma_TV): Sigma TV is a commercial network in Cyprus that commenced broadc...mix of original programs as well as popular foreign programming.
2. Sigma TV original programming (<http://dbpedia.org/resource/Category:Sigma_TV_original_programming>)
3. Sigma (dbr:Sigma)
4. Sigma Sigma Sigma (dbr:Sigma_Sigma_Sigma)
5. Sigma Sigma (dbr:Sigma_Sigma): Sigma Sigma (ΣΣ) is a men's upperclassmen honorary fraternity at...iversity of Cincinnati. This constitution shall not be amended."
6. Sigma Sigma Sigma (<http://dbpedia.org/resource/Category:Sigma_Sigma_Sigma>)
7. SIGMA (dbr:SIGMA)
8. Σίγμα (<http://dbpedia.org/resource/Σίγμα>)
9. \sigma (<http://dbpedia.org/resource/%5Csigma>)
10. ΣΊΓΜΑ (<http://dbpedia.org/resource/ΣΊΓΜΑ>)

[Assistant]
The most relevant entity for "Sigma TV" is dbr:Sigma_TV.

Next, I need to find the property related to "headquarters" for this entity. I will search for properties related to "headquarters" for dbr:Sigma_TV.

[Tool]
Top 10 property alternatives:
1. headquarters (dbp:headquarters)
2. headquarter (dbo:headquarter): populated place, organisation
3. logo (dbp:logo)
4. owners (dbp:owners)
5. foundation (dbp:foundation)
6. country (dbp:country)
7. country (dbo:country): The country where the thing is located., country
8. owner (dbp:owner)
9. website (dbp:website)
10. area (dbp:area)

No other items found

[Assistant]
There are two relevant properties: dbp:headquarters and dbo:headquarter. To ensure completeness, I will check both properties for the headquarters of dbr:Sigma_TV.

I will write a SPARQL query to retrieve the headquarters using both properties, and also try to get a label for the result if available.

[Tool]
Got 6 rows and 2 columns:
| hq                        | hqLabel        |
| ------------------------- | -------------- |
| Cyprus (dbr:Cyprus)       | Cyprus (en)    |

| Strovolos (dbr:Strovolos) | Strovolos (en) |
| Strovolos (dbr:Strovolos) | Strovolos (en) |

[Assistant]
The query returned three unique locations for the headquarters of Sigma TV: Cyprus, Nicosia, and Strovolos. These are all geographically related, with Strovolos being a suburb of Nicosia, which is the capital of Cyprus.

Here is the final SPARQL query and the answer.

[Tool] Stopped generation process

[User]
Feedback (status=refine):
The answer is correct in terms of content, as it lists the locations associated with Sigma TV's headquarters. However, the SPARQL query returns duplicate results for Cyprus, Nicosia, and Strovolos. To improve the output, the query should use SELECT DISTINCT to eliminate duplicates. Additionally, it would be helpful to optionally retrieve human-readable labels for the locations using rdfs:label in an OPTIONAL clause. The answer should also clarify that these are all locations associated with the headquarters, as the data does not specify a single, most precise location.

[Assistant]
Thank you for your feedback. To address your suggestions:

1. I will use SELECT DISTINCT to eliminate duplicate results.
2. I will include an OPTIONAL clause to retrieve human-readable labels for the locations using rdfs:label.
3. I will clarify in the answer that these are all locations associated with the headquarters, as the data does not specify a single, most precise location.

Here is the improved SPARQL query and answer.

[Tool] Stopped generation process

[User]
Feedback (status=done):
The SPARQL query correctly retrieves all headquarters locations associated with Sigma TV from DBpedia, using both dbp:headquarters and dbo:headquarter properties. The query returns the IRIs of the locations, and the labels are included as optional, which is appropriate. The answer accurately reflects the query results and notes the ambiguity in the data. No further refinement is needed.

[Assistant]
We have identified the correct entity for the conflict: dbr:Siege_of_Fort_Recovery.

Now, let's find office holders whose final resting place is North Bend, Ohio (dbr:North_Bend,_Ohio) and who were involved in the Siege of Fort Recovery (dbr:Siege_of_Fort_Recovery).

To do this, we need to:
- Find people whose final resting place is North Bend, Ohio.
- Among them, find those who held an office.
- Among them, find those who were involved in the Siege of Fort Recovery.

Let's first check which property is used for "final resting place" in DBpedia. I'll search for properties related to "resting place".

[Tool]
Top 10 property alternatives:
1. resting place (dbp:restingPlace)
2. resting place (dbo:restingPlace): person, place

8. place of burial (dbo:placeOfBurial): The place where the person has been buried., person, place
9. place of burial (dbp:placeOfBurial)
10. placeofburial (dbp:placeofburial)

[Assistant]
The most relevant properties for "final resting place" are dbo:restingPlace and dbp:restingPlace.

Next, let's check which property is used to indicate participation in a conflict, such as the Siege of Fort Recovery. I'll search for properties related to "conflict".

10. wars (dbp:wars)

[Assistant]
The most relevant properties for participation in a conflict are dbp:conflict, dbp:conflicts, and possibly dbo:battle.

Now, let's find people whose final resting place is North Bend, Ohio (dbr:North_Bend,_Ohio) using dbo:restingPlace or dbp:restingPlace.

It appears that there are no direct links in DBpedia for people whose final resting place is "North Bend, Ohio" using the common burial/resting place properties.

Given that, let's try a different approach: Let's search for notable people associated with North Bend, Ohio, and see if any of them are office holders and participated in the Siege of Fort Recovery.

I'll search for entities related to "North Bend, Ohio" to see if any notable people are directly associated.

Additionally, the query structure is problematic: it assumes a direct link between the person and the battle via a 'militaryService' node, which may not exist in DBpedia. Also, the use of 'dbp:office' is questionable, as office holders are usually linked via 'dbo:office' or similar properties. The query should be reworked to ensure proper linking between the person, their resting place (in North Bend), and their participation in the Siege of Fort Recovery. Please retry with a corrected and executable SPARQL query.

[Assistant]
Thank you for the feedback. Let's address the issues step by step:

1. The previous query assumed a direct structure via dbo:militaryService, which may not be reliable for all persons in DBpedia.
2. The property for office holding should be checked—dbo:office is more standard, but we should verify its usage.
3. The resting place should be linked to North Bend, Ohio, either directly or via the tomb memorial.
4. Participation in the Siege of Fort Recovery should be checked via all plausible properties (dbp:battles, dbp:war, dbo:battle, etc.).

Let's start by finding all people whose resting place is in North Bend, Ohio, using all plausible properties.

Failed to call function execute:
failed to parse input: no matching token found from position 339: '_Ohio || ?place = dbr:William_Henry_Harrison_Tomb_State_Memorial)
}'

[Assistant]
The error is due to the use of "||" in the FILTER clause, which is not valid SPARQL syntax. Instead, we should use "IN" or multiple FILTERs combined with "||".

Let's rewrite the query using the "IN" operator for the place.

[Tool]
Failed to call function execute:
failed to parse input: no matching token found from position 341: '_Ohio, dbr:William_Henry_Harrison_Tomb_State_Memorial))
}'

[Assistant]
It appears that the "IN" operator is not supported by the QLever endpoint. Instead, I will use a FILTER with logical OR ("||") inside the FILTER, but written correctly in SPARQL.

Here is the corrected approach:

```sparql
FILTER (?place = dbr:North_Bend,_Ohio || ?place = dbr:William_Henry_Harrison_Tomb_State_Memorial)
```

Let's try again with this structure.

[Tool]
Failed to call function execute:
failed to parse input: no matching token found from position 347: '_Ohio || ?place = dbr:William_Henry_Harrison_Tomb_State_Memorial)
}'

[Assistant]
It seems the QLever endpoint does not support the use of logical OR ("||") in FILTER expressions with IRIs. Instead, I will split the query into two parts using UNION, one for each possible resting place.

Let's construct the query using UNION for the two possible resting places.

[Tool]
Failed to call function execute:
failed to parse input: no matching token found from position 67: '_Ohio . }
  UNION
  { ?person dbo:restingPlace dbr:William_Henry_Harrison_Tomb_State_Memorial . }
  UNION
  { ?person dbp:restingPlace dbr:North_Bend,_Ohio . }
  UNION
  { ?person dbp:restingPlace dbr:William_Henry_Harrison_Tomb_State_Memorial . }
  UNION
  { ?person dbp:restingplace dbr:North_Bend,_Ohio . }
  UNION
  { ?person dbp:restingplace dbr:William_Henry_Harrison_Tomb_State_Memorial . }
  UNION
  { ?person dbo:placeOfBurial dbr:North_Bend,_Ohio . }
  UNION
  { ?person dbo:placeOfBurial dbr:William_Henry_Harrison_Tomb_State_Memorial . }
  UNION
  { ?person dbp:placeOfBurial dbr:North_Bend,_Ohio . }
  UNION
  { ?person dbp:placeOfBurial dbr:William_Henry_Harrison_Tomb_State_Memorial . }
  UNION
  { ?person dbp:placeofburial dbr:North_Bend,_Ohio . }
  UNION
  { ?person dbp:placeofburial dbr:William_Henry_Harrison_Tomb_State_Memorial . }
}'

[Assistant]
The error is likely due to the use of commas in the IRIs (e.g., dbr:North_Bend,_Ohio). In DBpedia, IRIs with commas are encoded with underscores, but let's verify the correct IRI for "North Bend, Ohio".

From our earlier search, the IRI is:
<http://dbpedia.org/resource/North_Bend,_Ohio>

But in SPARQL, we should use the full IRI in angle brackets.

Let's try a minimal query to see if anyone is linked with dbo:restingPlace to <http://dbpedia.org/resource/North_Bend,_Ohio>.

Feedback (status=refine):
The query is mostly correct, but it could be improved for completeness and clarity. It currently only returns the IRI of the person, but the question specifically asks for the 'office holder.' To ensure the answer is fully aligned with the question, the query should also return the office(s) held by the person, using an OPTIONAL clause to retrieve the office label for clarity. Additionally, the query should use rdfs:label to optionally provide human-readable labels for the person and the office. This would make the answer more informative and user-friendly.

[Assistant]
Thank you for the feedback. To improve the query:

- I will return the person's IRI and optionally their rdfs:label.
- I will also return the office(s) held by the person, and optionally the office's rdfs:label for clarity.
- I will use OPTIONAL for the labels to ensure the query is robust even if labels are missing.

Here is the refined SPARQL query:

```sparql
SELECT DISTINCT ?person ?personLabel ?office ?officeLabel WHERE {
  ?person dbp:restingplace <http://dbpedia.org/resource/William_Henry_Harrison_Tomb_State_Memorial> .
  ?person dbp:battles ?battles .
  FILTER(CONTAINS(LCASE(STR(?battles)), "siege of fort recovery"))
  ?person dbp:office ?office .
  OPTIONAL { ?person rdfs:label ?personLabel . FILTER(LANG(?personLabel) = "en") }
  OPTIONAL { ?office rdfs:label ?officeLabel . FILTER(LANG(?officeLabel) = "en") }
}
```

This will provide the IRI and English label for both the person and their office(s).

Now, I will submit this as the final answer.

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:
dbpedia at https://qlever.cs.uni-freiburg.de/api/dbpedia

You can use the following SPARQL prefixes implicitly in all functions:
dbo: <http://dbpedia.org/ontology/

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 is the name of the artist which worked on the subsequent work of Ella Loves Cole?

[Assistant]
Let's break down the question:

1. "Ella Loves Cole" is likely an artwork or album. We need to identify its entity in DBpedia.
2. "Subsequent work" refers to the next work after "Ella Loves Cole". We need to find the property that links works in sequence (e.g., "subsequent work", "next work", "follow-up", etc.).
3. We need to find the artist of that subsequent work.

First, I will search for "Ella Loves Cole" in DBpedia to identify its entity.

10. Ella (dbr:Ella)

[Assistant]
The entity for "Ella Loves Cole" in DBpedia is dbr:Ella_Loves_Cole, which is a 1972 studio album by Ella Fitzgerald.

Next, I need to find the property that links to the "subsequent work" or "next work" of this album. I will search for properties related to "subsequent work" or "next work" in DBpedia.

[Tool]
Top 10 property alternatives:
1. next title (dbp:nextTitle)

[Assistant]
The property dbp:nextTitle appears to represent the "next" or "subsequent" work for "Ella Loves Cole". Now, I need to find the value of dbp:nextTitle for dbr:Ella_Loves_Cole to identify the subsequent work.

I will list the triples for dbr:Ella_Loves_Cole with the property dbp:nextTitle.
