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

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. Search for the 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. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

You have access to the following knowledge graphs:
wikidata at http://localhost:7001 without notes

You are provided with the following notes across all knowledge graphs:

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- 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.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- 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.
- 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.
- 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.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

[User] Who's the author of The Hellbound Heart ?

[Assistant] Step 1 — I will search Wikidata for an entity matching the title "The Hellbound Heart" to find its Q-id. I'll now run an entity search for that title.

[Tool]
Top 10 entity alternatives:
1. The Hellbound Heart (wd:Q3521239): is instance of literary work / novella by Clive Barker

10. The Roue's Heart (wd:Q3522553), also known as Roue's Heart: 1909 film by D. W. Griffith / is instance of short film

[Assistant] Step 2 — I'll list triples for the entity wd:Q3521239 to find which property holds the author (likely wdt:P50). I'll call list(subject=wd:Q3521239).

[Tool]
Got 109 rows and 3 columns, showing the first 10 rows below:
| subject                           | property                            | object                              |

[Assistant] Step 3 — I'll run a SPARQL query that retrieves the author (P50) of the work The Hellbound Heart (wd:Q3521239). The query will return the author's IRI and an optional English label. I'll now execute that query.

[Tool]

[Assistant] I'll run an ASK query that checks whether the Wikidata item for After Eight (wd:Q388973) has Unilever (wd:Q157062) as its manufacturer using the manufacturer property (wdt:P176). This will directly answer True/False. Now I'll execute the query.

[Tool] False

[Assistant] The ASK returned False, meaning After Eight is not manufactured by Unilever according to Wikidata. But I should also check who is listed as manufacturer or owner to provide context. I'll query for the manufacturer (P176), creator (P170), and owner (P127) of After Eight.

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

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. Search for the 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. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

You have access to the following knowledge graphs:
wikidata at http://localhost:7001 without notes

You are provided with the following notes across all knowledge graphs:
No notes available

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

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- 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.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- 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.
- 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.
- 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.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

[Assistant]
We have various entities including non-business organizations (political action committee, school). The user asked: \"Which businesses are founded by the person in charge of Tesla?\" The person in charge (CEO) is Elon Musk. So we should return the businesses (companies/enterprises) he founded.

I need to craft a final SPARQL query that lists organizations with wdt:P112 wd:Q317521 that are instances (wdt:P31) of any class that is subclass of 'business' or 'company' or 'enterprise' or 'company type'. Better approach: require that ?org wdt:P31 ?class and ?class wdt:P279* / rdfs:subClassOf* to wd:Q4830453 or be equal to wd:Q4830453 or wd:Q783794 or wd:Q6881511. Use property path: ?class wdt:P279* wd:Q4830453 or wd:Q783794 or wd:Q6881511. Also include organizations that directly have instance of those classes. I'll write query selecting distinct ?org and labels, and maybe include the class label. Then execute.

I must explain thought process before and after each step and function call per developer instructions. I've been doing that. Continue: I'll build the SPARQL query and execute it.

I'll execute a SPARQL query that finds all items with founded by = Elon Musk and whose instance (P31) is a subclass (P279*) of business (Q4830453), company (Q783794), or enterprise (Q6881511). I'll return the org IRIs and English labels.

[Assistant]
The query returned 19 rows (some organizations appear multiple times because they have multiple instance types). I should reduce duplicates: return DISTINCT ?org with label and group or sample type maybe. But requirement: The SPARQL query should always return the actual identifiers/IRIs. It's okay to include only distinct ?org and label. I'll adjust to get DISTINCT ?org ?orgLabel and maybe GROUP_CONCAT types? But GROUP_CONCAT might not be supported; QLever likely supports GROUP_CONCAT. But simpler: return DISTINCT ?org ?orgLabel and optionally one type (MIN(?type)?) But unnecessary. The user asked which businesses; listing org IRIs and labels is sufficient.

I'll execute final query returning distinct organizations that are businesses founded by Elon Musk, with their English labels. Then present results.

Construct final query: SELECT DISTINCT ?org ?orgLabel WHERE { ?org wdt:P112 wd:Q317521 . ?org wdt:P31 ?type . VALUES ?root { wd:Q4830453 wd:Q783794 wd:Q6881511 } ?type wdt:P279* ?root . OPTIONAL label. } ORDER BY ?orgLabel

Execute it to produce final results to include in answer via functions.answer. Also I must explain thought process before and after the function call; I've been doing that. Now call answer with final SPARQL and an answer string listing results.

But per tool instructions, functions.answer will execute the final SPARQL query on the specified kg. It will also stop generation. So include the final SPARQL query string identical to the one I'll execute.

Let's run functions.answer with that query and provide answer text summarizing the businesses found (list IRIs and labels). Need to ensure answer string matches query results. We have earlier result set of orgs: from the 19 rows we need unique org labels. From previous execute we saw Neuralink, OpenAI, PayPal, SpaceX, xAI, X Corp., X Holdings Corp, Zip2, Thud, Texas Institute of Technology & Science (likely hoax?), Astra Nova School (not business) - but query filters out non-business. Let's get full list from earlier result by running the distinct org query again via answer; functions.answer will run it and we must provide the answer text derived solely from the SPARQL result (no extra computation outside SPARQL). But we are allowed to summarize based on query results? The developer rule: "Use the answer function to finalize your answer and stop the generation process." Also "Always execute your final SPARQL query before giving an answer." functions.answer will execute. The answer string should be current. But must ensure the answer string is consistent with query results. To be safe, perhaps I should run execute then produce answer with list. But final must use functions.answer per instructions 4. But earlier I executed similar query. I'll run functions.answer with final query and include answer listing the businesses (their labels and IRIs). Use labels from previous result: need to extract distinct labels: from previous we saw Neuralink, OpenAI, PayPal, SpaceX, Zip2, xAI, Thud, Texas Institute of Technology & Science, X Corp., X Holdings Corp, America PAC (?) America PAC wasn't included because PAC is not business—my query filters by subclass of business so PAC shouldn't be included. But earlier full results included 30 items, this business-filter query returned 19 rows but unique orgs probably are: Neuralink, OpenAI, PayPal, SpaceX, Zip2, xAI, Thud, Texas Institute of Technology & Science, X Corp., X Holdings Corp, maybe SolarCity? Did Elon found SolarCity (Q457338)? He was a co-founder of SolarCity. Search among found-by list earlier. Let's quickly run a query to list DISTINCT ?org and label from final query using functions.execute to be precise. We already executed a similar query result which had 19 rows; but we only saw some rows. I'll run the distinct org query via execute to get all rows. But we must use functions.execute now; allowed. Let's do that before final answer to ensure accuracy.

I'll call execute with the distinct org query.

Using entities:
Cage the Elephant (wd:Q68061)

Using properties:
genre (wd:P136 as wdt), also known as artistic genre, art style, film genre, genre of literature, genre of music, etc.

Answer:
I will summarize my steps and the result.

Thought process and steps taken:
1) Found the Wikidata item for "Cage the Elephant": wd:Q68061.
2) Listed its genres (property wdt:P136) and verified the items: blues (wd:Q9759), punk rock (wd:Q3071), alternative rock (wd:Q11366), indie rock (wd:Q183504), psychedelic rock (wd:Q206159), and garage rock (wd:Q211573).
3) Wrote and executed a SPARQL query that: retrieves English rdfs:label for each genre, computes the string length (STRLEN) of each English label, finds the minimum length, and returns the genre(s) with that minimum length.

Final SPARQL query (already executed):
SELECT ?genre ?label ?len WHERE {
  {
    SELECT (MIN(?l) AS ?minLen) WHERE {
      wd:Q68061 wdt:P136 ?g .
      ?g rdfs:label ?lab .
      FILTER(LANG(?lab) = "en") .
      BIND(STRLEN(STR(?lab)) AS ?l)
    }
  }
  wd:Q68061 wdt:P136 ?genre .
  ?genre rdfs:label ?label .
  FILTER(LANG(?label) = "en") .
  BIND(STRLEN(STR(?label)) AS ?len) .
  FILTER(?len = ?minLen)
} ORDER BY ?label

Answer:
The genre with the fewest English characters is blues (wd:Q9759), English label "blues", length 5 characters.

Which genre that Cage the Elephant belongs to has the fewest english characters?

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

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. Search for the 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. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- 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.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- 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.
- 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.
- 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.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

[User] Which genre that Cage the Elephant belongs to has the fewest english characters?

[Assistant]
I will first find the Wikidata item for "Cage the Elephant", then retrieve its genres (property P136). I'll verify the genres exist and have English labels, and then write a SPARQL query that computes the length (in characters) of each genre's English label and selects the genre(s) with the minimum length.

I'll search for the entity "Cage the Elephant" now.

| Cage the Elephant (wd:Q68061) | genre (wdt:P136) | garage rock (wd:Q211573)      |

[Assistant]
I'll run a SPARQL query that:
- Gets all genres (wdt:P136) of Cage the Elephant (wd:Q68061),
- Retrieves their English rdfs:label,
- Computes the character length of each English label with STRLEN,
- Finds the minimum length and returns the genre(s) whose label length equals that minimum.

Now I'll execute that query.
