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:
wikidata at https://qlever.cs.uni-freiburg.de/api/wikidata-sebastian with notes:
1. When direct properties are missing, chain related properties (e.g., child→child for grandchildren) or search for indirect connections to answer complex relationship queries.
2. For set/class queries (e.g., all cities, all holidays), use instance/subclass chains (P31/P279) for completeness and relevant filters. Be aware of data incompleteness and schema inconsistencies in Wikidata.
3. If queries return too many irrelevant or too few results, try varying properties (country, location, observed in, etc.) and subclass chains, but be ready to report data/model limitations if results remain incomplete or noisy.
4. When a direct property or class is missing or inconsistently used, try related or broader properties/classes (e.g., use inception for independence date, or musical work/composition for musicals) to increase recall.
5. For calculated properties (e.g., population density), combine relevant direct properties (e.g., population, area) in SPARQL queries, as Wikidata may not store the derived value directly.
6. When entity search returns multiple candidates, use context (description, instance type, location, etc.) to disambiguate and select the most relevant entity for the query.

No general notes for all knowledge graphs available

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.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. 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.
5. 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.
6. 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.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. 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 query returned many specific year Nobel Prizes, which are instances of the Nobel Prize class. However, the question is about how many different prizes were established by Alfred Nobel, not the number of yearly awards.

I will try to find the main categories of Nobel Prizes (e.g., Nobel Prize in Physics, Nobel Prize in Chemistry, etc.) which are subclasses or instances of the Nobel Prize class wd:Q7191. Then I will check if these main categories have Alfred Nobel as the founder or creator.

[Assistant]
There are 5 main Nobel Prizes listed as subclasses of the Nobel Prize class (wd:Q7191):
- Nobel Peace Prize (wd:Q35637)
- Nobel Prize in Literature (wd:Q37922)
- Nobel Prize in Physics (wd:Q38104)
- Nobel Prize in Chemistry (wd:Q44585)
- Nobel Prize in Physiology or Medicine (wd:Q80061)

I will now check if these prizes have Alfred Nobel (wd:Q23810) as their founder or creator. I will check the property "founder" or "creator" for these prizes.

[Tool]
Top 10 property alternatives:
1. founded by, also known as starter, started by, institutor, instituted by, founders (wd:P112 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): founder or co-founder of this organization, religion, place or entity, subproperty of creator
2. notable work, also known as representative of artwork type, representative work, significance, significant works, they created (wd:P800 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): notable scientific, artistic or literary work, or other work of significance among subject's works
3. inception, also known as inception date, founding date, founded in, founded on date, founded on (wd:P571 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): time when an entity begins to exist; for date of official opening use P1619, subproperty of start time
4. collection creator, also known as archive creator, creator, collector, collected by, archive of (wd:P6241 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): entity (person, organization, etc.) that caused a record or collection to be produced or gathered
5. creator, also known as art by, visual artist, sculptor, sculpted by, realized by (wd:P170 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): maker of this creative work or other object (where no more specific property exists)
6. author, also known as co-author, written by, writer, poet, playwright (wd:P50 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): main creator(s) of a written work (use on works, not humans); us...hor name string) when Wikidata item is unknown or does not exist, subproperty of creator
7. location of formation, also known as originates from, place of incorporation, place of establishment, place of formation, place of foundation (wd:P740 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): location where a group or organization was formed, subproperty of location of creation

[Assistant] The property "founded by" (wdt:P112) seems to be the most relevant to check if Alfred Nobel founded these prizes. I will check for each of the main Nobel Prizes if they have a "founded by" property with Alfred Nobel as the value.

[Tool] Got no rows and 2 columns

[Assistant] None of the main Nobel Prizes have the property "founded by" with Alfred Nobel as the value. I will try the property "creator" (wdt:P170) instead to see if Alfred Nobel is listed as the creator of these prizes.

[Tool] Got no rows and 2 columns

[Assistant]
None of the main Nobel Prizes have Alfred Nobel as the creator (wdt:P170) either. I will try to find if there is any property linking the Nobel Prizes to Alfred Nobel as the founder or creator indirectly or if there is a statement about the number of prizes established by him.

I will try to find the number of Nobel Prizes established by Alfred Nobel by querying for awards or prizes that have Alfred Nobel as the founder or creator or are instances or subclasses of Nobel Prize. Then I will count the distinct prizes.

[Tool]
Got 1 row and 1 column:
| count       |

| 0 (xsd:int) |

[Assistant]
There are no prizes that are instances or subclasses of Nobel Prize (wd:Q7191) that have Alfred Nobel (wd:Q23810) as the founder (wdt:P112).

I will try a different approach: I will check the Nobel Prize entity (wd:Q7191) itself if it has Alfred Nobel as the founder or creator. Then I will count the number of subclasses of Nobel Prize to determine how many prizes were established by Alfred Nobel.

[Tool]
Got 1 row and 1 column:
| founder                  |
| ------------------------ |
| Alfred Nobel (wd:Q23810) |

[Assistant] The Nobel Prize entity (wd:Q7191) has Alfred Nobel (wd:Q23810) as its founder (wdt:P112). Now I will count the number of subclasses of Nobel Prize to determine how many prizes were established by Alfred Nobel.

[Tool]
Got 1 row and 1 column:
| count       |
| ----------- |
| 7 (xsd:int) |

[Assistant]
There are 7 subclasses of the Nobel Prize (wd:Q7191), which is founded by Alfred Nobel. This means Alfred Nobel established 7 different prizes.

I will now provide the final answer.

[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:
wikidata at https://qlever.cs.uni-freiburg.de/api/wikidata-sebastian with notes:
1. When direct properties are missing, chain related properties (e.g., child→child for grandchildren) or search for indirect connections to answer complex relationship queries.
2. For set/class queries (e.g., all cities, all holidays), use instance/subclass chains (P31/P279) for completeness and relevant filters. Be aware of data incompleteness and schema inconsistencies in Wikidata.
3. If queries return too many irrelevant or too few results, try varying properties (country, location, observed in, etc.) and subclass chains, but be ready to report data/model limitations if results remain incomplete or noisy.
4. When a direct property or class is missing or inconsistently used, try related or broader properties/classes (e.g., use inception for independence date, or musical work/composition for musicals) to increase recall.
5. For calculated properties (e.g., population density), combine relevant direct properties (e.g., population, area) in SPARQL queries, as Wikidata may not store the derived value directly.
6. When entity search returns multiple candidates, use context (description, instance type, location, etc.) to disambiguate and select the most relevant entity for the 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. 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.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. 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.
5. 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.
6. 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.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. 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.

[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:
wikidata at https://qlever.cs.uni-freiburg.de/api/wikidata-sebastian with notes:
1. When direct properties are missing, chain related properties (e.g., child→child for grandchildren) or search for indirect connections to answer complex relationship queries.
2. For set/class queries (e.g., all cities, all holidays), use instance/subclass chains (P31/P279) for completeness and relevant filters. Be aware of data incompleteness and schema inconsistencies in Wikidata.
3. If queries return too many irrelevant or too few results, try varying properties (country, location, observed in, etc.) and subclass chains, but be ready to report data/model limitations if results remain incomplete or noisy.
4. When a direct property or class is missing or inconsistently used, try related or broader properties/classes (e.g., use inception for independence date, or musical work/composition for musicals) to increase recall.
5. For calculated properties (e.g., population density), combine relevant direct properties (e.g., population, area) in SPARQL queries, as Wikidata may not store the derived value directly.
6. When entity search returns multiple candidates, use context (description, instance type, location, etc.) to disambiguate and select the most relevant entity for the 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. 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.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. 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.
5. 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.
6. 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.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. 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] After whom is the Riemannian geometry named?

[Assistant] The question asks for the person after whom the Riemannian geometry is named. This is likely a person with the last name "Riemann." To confirm this, I will search for the entity "Riemannian geometry" in Wikidata and check the property that indicates the person it is named after or the creator/inventor of the concept. The relevant property might be "named after" (P138) or "creator" (P170). I will start by searching for the entity "Riemannian geometry" in Wikidata.

[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:
wikidata at https://qlever.cs.uni-freiburg.de/api/wikidata-sebastian with notes:
1. When direct properties are missing, chain related properties (e.g., child→child for grandchildren) or search for indirect connections to answer complex relationship queries.
2. For set/class queries (e.g., all cities, all holidays), use instance/subclass chains (P31/P279) for completeness and relevant filters. Be aware of data incompleteness and schema inconsistencies in Wikidata.
3. If queries return too many irrelevant or too few results, try varying properties (country, location, observed in, etc.) and subclass chains, but be ready to report data/model limitations if results remain incomplete or noisy.
4. When a direct property or class is missing or inconsistently used, try related or broader properties/classes (e.g., use inception for independence date, or musical work/composition for musicals) to increase recall.
5. For calculated properties (e.g., population density), combine relevant direct properties (e.g., population, area) in SPARQL queries, as Wikidata may not store the derived value directly.
6. When entity search returns multiple candidates, use context (description, instance type, location, etc.) to disambiguate and select the most relevant entity for the 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. 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.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. 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.
5. 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.
6. 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.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. 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.

6. 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.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. 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.

SPARQL execution failed:
Error while executing a SERVICE request to <http://wikiba.se:80/ontology#label>: SERVICE responded with HTTP status code: 301, Moved Permanently. First 100 bytes of the response: '<html>
<head><title>301 Moved Permanently</title></head>
<body>
<center><h1>301 Moved Permanently'

[Assistant] The query failed due to the use of the SERVICE wikibase:label which is not supported by the QLever endpoint. I will rewrite the query without using SERVICE wikibase:label and instead use optional rdfs:label to get the album label.
