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] When was the beginning of Romanticism ?

[Assistant]
To answer the question "When was the beginning of Romanticism?", I need to find the starting date or inception date of the artistic and intellectual movement called Romanticism.

Step 1: Identify the entity for Romanticism in Wikidata.
Step 2: Identify the property that represents the beginning or inception date of Romanticism.
Step 3: Query the inception date of Romanticism.

I will start by searching for the entity "Romanticism" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. Romanticism, also known as Romantic movement, Romantic period, romantics, Romantic, Romantic era (wd:Q37068): artistic, literary, musical, and intellectual movement, instance of architectural style, instance of cultural movement, instance of literary movement, instance of art movement, instance of art style
2. Romantic literature in English, also known as English romanticism, Romanticism (wd:Q24884734)
3. Romanticism (wd:Q7362837): instance of history journal, academic journal
4. Romanticism (wd:Q65247698): 2019 single by Mrs. GREEN APPLE, instance of single
5. Romanticism (wd:Q18192423)
6. Romanticism (wd:Q103964154): instance of encyclopedia article, encyclopedia article
7. Romanticism (wd:Q101871151): instance of chapter, chapter
8. romanticism (wd:L326895)
9. romanticism (wd:L326895-F1)
10. romanticism (wd:L612332-S2)

[Assistant] The most relevant entity for the artistic and intellectual movement Romanticism is wd:Q37068. Next, I will look for the property that indicates the beginning or inception date of this movement. Common properties for inception or start date are P571 (inception) or P580 (start time). I will check the inception date (P571) for the entity wd:Q37068.

[Tool] Got no rows and 2 columns

[Assistant] The direct property P571 (inception) does not have a value for Romanticism (wd:Q37068). I will try to find other related properties that might indicate the beginning or start date of Romanticism. I will search for properties related to "start" or "beginning" for this entity.

[Tool]

6. followed by, also known as prequel of, sequel is, succeeded by, then, successor (wd:P156 as wdt/p): immediately following item in a series of which the subject is a...een replaced, e.g. political offices, use "replaced by" (P1366)]
7. end time, also known as ends, to, endtime, fall date, ineffective (wd:P582 as wdt/p): moment when an entity ceases to exist and a statement stops being entirely valid or no longer be true, subproperty of point in time
8. pronunciation audio, also known as audio pronunciation, listen (wd:P443 as wdt/p): audio file with pronunciation, subproperty of audio
9. image, also known as img, infobox image, photo, photograph, picture (wd:P18 as wdt/p): image of relevant illustration of the subject; if available, als...tor map, flag image, signature image, logo image, collage image)

[User] How many people nominated for the nobel prize in chemistry didn't ever win it?

[Assistant]
To answer this question, I need to find people who were nominated for the Nobel Prize in Chemistry but never won it.

Step 1: Identify the property or entity for "Nobel Prize in Chemistry" and the property for "nominated for" and "award received" or "won".
Step 2: Query for people who were nominated for the Nobel Prize in Chemistry.
Step 3: Filter out those who have won the Nobel Prize in Chemistry.
Step 4: Count the remaining people.

I will start by searching for the entity "Nobel Prize in Chemistry" in Wikidata.

10. Nobel Prize in Chemistry 2015 (wd:Q48913284): instance of Nobel Prize in Chemistry

[Assistant]
The entity for "Nobel Prize in Chemistry" is wd:Q44585.

Next, I need to find the property for "nominated for" and "award received" or "won" related to the Nobel Prize in Chemistry.

I will search for properties related to "nominated" and "award" to identify the correct properties to use in the query.

[Tool]
Top 10 property alternatives:
1. nominated by (wd:P4353 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): who nominated a person for an office or award; can be used as a qualifier
2. nominated for, also known as nominee for award, shortlisted for, selected for award, selected for, nominee for (wd:P1411 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): award nomination received by a person, organisation or creative work (inspired from "award received" (Property:P166))
3. nominee, also known as award nominee (wd:P2453 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): qualifier used with “nominated for” to specify which person or organization was nominated
4. for work, also known as awarded for work, citation for award, for their work on, nominated for work (wd:P1686 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): qualifier of award received (P166) to specify the work that an award was given to the creator for
5. award received, also known as winner of, win, recognition title, received award, award won (wd:P166 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): award or recognition received by a person, organization or creative work
6. conferred by, also known as presented by, officiated by, issued by, granted by, given by (wd:P1027 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): person or organization who grants an award, certification, grant, or role
7. winner, also known as nominee, prizewinner, titleholder, top dog, victor (wd:P1346 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): winner of a competition or similar event, not to be used for awa...ssibly qualified with "for work" (P1686)) or for wars or battles, subproperty of participating team, subproperty of participant

10. eligible recipient, also known as eligible recipient for award, type of recipient who is eligible for this award (wd:P8115 as psn/wdt/ps/prn/pr/wdtn/pq/pqv/p/prv/psv/pqn): party that is eligible to receive something, like an award, grant or prize

[Assistant]
The property "nominated for" (wdt:P1411) seems to be the correct property to indicate nomination for an award. The property "award received" (wdt:P166) indicates awards won.

I will now construct a query to find people who were nominated for the Nobel Prize in Chemistry (wd:Q44585) but did not receive it as an award. I will count such people.

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.

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.

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] Which started first: impressionism or expressionism (art movements)?

[Assistant]
To answer the question of which art movement started first, impressionism or expressionism, I need to find the starting dates (inception or inception date) of both art movements in Wikidata. Then I can compare these dates to determine which one started earlier.

Step 1: Search for the entities "Impressionism" and "Expressionism" in Wikidata to get their identifiers.

[Tool]

[Assistant]
I found the entities for the art movements:
- Impressionism: wd:Q40415
- Expressionism: wd:Q80113

Next, I will query the inception dates (start dates) for these two art movements to determine which started first.

[Tool]
Got 1 row and 3 columns:
| movement                  | movementLabel      | inception                           |

| impressionism (wd:Q40415) | impressionism (en) | 1860-01-01T00:00:00Z (xsd:dateTime) |

[Assistant] I got the inception date for Impressionism as 1860-01-01, but there is no inception date returned for Expressionism in this query. I will try to check if Expressionism has an inception date property or if it is stored under a different property or qualifier. I will specifically check the properties of Expressionism (wd:Q80113) to find the inception date or start date.

[Tool] Got no rows and 3 columns

[Assistant] There is no direct inception date (P571) for Expressionism (wd:Q80113). I will try to check other related properties that might indicate the start date, such as "start time" (P580) or "date of inception" (P571) with qualifiers. I will list all properties of Expressionism to find a suitable date property.

[Assistant]
I found that Expressionism (wd:Q80113) has a "start time" (P580) property with the value 1900-01-01. This can be considered as the start date for Expressionism.

Now I have:
- Impressionism inception: 1860-01-01
- Expressionism start time: 1900-01-01

I will finalize the answer based on this information. Impressionism started first.

[Tool] Stopped generation process


I could not find a specific entity for Bryan Evenson in Wikidata despite multiple searches. Without the entity, I cannot query the universities where he was educated or worked. Therefore, I cannot answer if Bryan Evenson worked for at least one university where he was educated.

Did Bryan Evenson work for at least one university where he was educated at?

[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.

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 property "employer" (wdt:P108) is used to indicate the person or organization for which the subject works or worked. This is the property I will use to find the universities where Bryan Evenson worked.

Since I have not found the entity for Bryan Evenson yet, I will try to find any person named Bryan Evenson who has the property "educated at" or "employer" linked to a university. I will start by searching for humans named Bryan Evenson.

[Assistant]
I could not find a direct entity for Bryan Evenson in Wikidata. Due to the lack of a specific entity for Bryan Evenson, I am unable to construct a precise query to check if he worked for at least one university where he was educated.

Therefore, I cannot provide a reliable answer to the question based on the available data 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.

[User] Was the first album of the band Darkside released in 2012?

[Assistant] To answer this question, I need to find the band entity for "Darkside" and then identify their first album and its release date. I will start by searching for the band entity "Darkside" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. darkcore, also known as darkside jungle, darkcore jungle, darkside hardcore, darkside (wd:Q11693017)
2. DarkSide, also known as DarkSide (hacking group) (wd:Q106777661): hacking group believed to be behind the Colonial Pipeline cyberattack, instance of threat actor, instance of hacker group
3. Darkside (wd:Q16954319): American electronic music duo, instance of musical group

10. Darkside (wd:Q85755740): instance of musical work/composition, 2021 single by Blink-182

[Assistant] The band "Darkside" as an American electronic music duo is represented by the entity wd:Q16954319. Next, I will find the albums of this band and check the release date of their first album to see if it was released in 2012.

[Tool] Got no rows and 3 columns

[Assistant] The query to find albums of the band Darkside (wd:Q16954319) using property P175 (performer) did not return any results. This might be because the band is not listed as the performer directly on the album items. I will try to find albums where the band is the creator or main artist using other properties like P86 (composer) or P361 (part of). I will also try to find albums where the band is the main subject or creator.

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 previous query failed due to the use of the SERVICE wikibase:label, which is not supported by the QLever SPARQL endpoint. I will rewrite the query without using SERVICE wikibase:label and instead use optional rdfs:label to get album labels. I will also try to find albums where the band is the main artist or creator using properties like P175 (performer) or P86 (composer).

[Assistant] The first album of the band Darkside is "Psychic" released in 2013, not in 2012. Therefore, the answer to the question is no, the first album of the band Darkside was not released in 2012. I will now provide the final answer.
