[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.

Available knowledge graphs:
- wikidata at http://localhost:7001 with prefix index for entities and similarity index for properties

Index types used for entities and properties:
- Prefix index: Retrieves items by overlap between query keywords and item words. The query keywords can match item words exactly or as prefixes.
- Similarity index: Retrieves items by cosine similarity between their embeddings and the query embedding.

SPARQL prefixes for use in function calls:

Additional rules to follow:
- 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 ask the user for clarifications without first attempting to complete the task. If the task input is incomplete or ambiguous, try to make reasonable assumptions and document them.
- 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] How many works that are based on Spider-Man has Venom been a part of?

[Assistant]
The properties "present in work" (wdt:P1441) and "characters" (wdt:P674) seem relevant for linking works and characters. "Present in work" is used to indicate the work in which a fictional entity appears. "Characters" is used to indicate characters that appear in a work. I will use "present in work" (wdt:P1441) to find works in which Venom (wd:Q1621261) appears. Then I will filter those works to find which are based on Spider-Man (wd:Q79037) using the "based on" property (wdt:P144). I will count the number of such works. I will now construct the SPARQL query for this.

execute

SELECT (COUNT(DISTINCT ?work) AS ?count) WHERE {
  ?work wdt:P144 wd:Q79037 .  # works based on Spider-Man
  wd:Q1621261 wdt:P1441 ?work .  # Venom present in work
}

Got 1 row and 1 column:
| count       |
| ----------- |
| 0 (xsd:int) |

[Assistant]
The query result shows 0 works that are based on Spider-Man and have Venom as a part using the property "present in work" (wdt:P1441). I will try the other property "characters" (wdt:P674) to link works and characters to see if it yields any results. I will modify the query to use this property instead.

SELECT (COUNT(DISTINCT ?work) AS ?count) WHERE {
  ?work wdt:P144 wd:Q79037 .  # works based on Spider-Man
  ?work wdt:P674 wd:Q1621261 .  # works with Venom as character
}

Got 1 row and 1 column:
| count       |
| ----------- |
| 0 (xsd:int) |

[Assistant]
The query result again shows 0 works that are based on Spider-Man and have Venom as a character using the property "characters" (wdt:P674). Since these direct properties did not yield results, I will try to find works that are based on Spider-Man and then check if Venom is linked to these works by any property related to cast or characters. I will first find some works based on Spider-Man to examine their properties.

SELECT ?work ?workLabel WHERE {
  ?work wdt:P144 wd:Q79037 .
  OPTIONAL { ?work rdfs:label ?workLabel FILTER(LANG(?workLabel) = "en") }

[Assistant]
I found some works based on Spider-Man. Now I will check the properties of one of these works, for example, "Spider-Man: No Way Home - The More Fun Stuff Version" (wd:Q113471777), to see how characters or cast members are linked.

[Assistant]
The property "cast member" (wdt:P161) is used to link works to actors or characters in the work. I will now query for works that are based on Spider-Man (wdt:P144 wd:Q79037) and have Venom (wd:Q1621261) as a cast member (wdt:P161). I will count these works.

execute

SELECT (COUNT(DISTINCT ?work) AS ?count) WHERE {
  ?work wdt:P144 wd:Q79037 .  # works based on Spider-Man
  ?work wdt:P161 wd:Q1621261 .  # works with Venom as cast member
}

Got 1 row and 1 column:
| count       |
| ----------- |
| 0 (xsd:int) |

[Assistant]
The query result shows 0 works that are based on Spider-Man and have Venom as a cast member using the property "cast member" (wdt:P161). Since Venom is a fictional character, it might not be directly linked as a cast member. I will try to find works where Venom is a character using the property "characters" (wdt:P674) and that are based on Spider-Man. I will query for works that are based on Spider-Man and have Venom as a character.

SELECT (COUNT(DISTINCT ?work) AS ?count) WHERE {
  ?work wdt:P144 wd:Q79037 .  # works based on Spider-Man
  ?work wdt:P674 wd:Q1621261 .  # works with Venom as character
}

Got 1 row and 1 column:
| count       |
| ----------- |
| 0 (xsd:int) |

[Assistant]
The query result again shows 0 works that are based on Spider-Man and have Venom as a character using the property "characters" (wdt:P674). It seems there is no direct link between Venom and works based on Spider-Man in the data. I will try a broader approach: find works where Venom appears (using "present in work" wdt:P1441) and check if those works are based on Spider-Man (wdt:P144). I will return the count of such works.

SELECT (COUNT(DISTINCT ?work) AS ?count) WHERE {
  wd:Q1621261 wdt:P1441 ?work .  # works where Venom is present
  ?work wdt:P144 wd:Q79037 .  # works based on Spider-Man
}

Got 1 row and 1 column:
| count       |
| ----------- |
| 0 (xsd:int) |

[Assistant]
The query result still shows 0 works where Venom is present and that are based on Spider-Man. It appears that the data does not explicitly link Venom to works based on Spider-Man in a way that can be queried with these properties. I will now try to find works where Venom is present or a character, without the constraint of being based on Spider-Man, to see if such works exist at all. This will help verify if the data contains works with Venom.

SELECT ?work ?workLabel WHERE {
  { wd:Q1621261 wdt:P1441 ?work } UNION { ?work wdt:P674 wd:Q1621261 }
  OPTIONAL { ?work rdfs:label ?workLabel FILTER(LANG(?workLabel) = "en") }

[Assistant]
There are works where Venom is present or a character, including some Spider-Man related works like "Spider-Man 3" (wd:Q182212). I will check if these works are based on Spider-Man (wd:Q79037) or if they are standalone works. I will now check the "based on" property for "Spider-Man 3" (wd:Q182212).

list

wd:Q182212

[Assistant]
The work "Spider-Man 3" (wd:Q182212) does not have a "based on" property linking it to Spider-Man (wd:Q79037). It might be considered a Spider-Man work by its own title or classification. I will now try to find works that have Venom as a character or present and have a title or label containing "Spider-Man" to approximate works based on Spider-Man. I will count such works.

execute

SELECT (COUNT(DISTINCT ?work) AS ?count) WHERE {
  { wd:Q1621261 wdt:P1441 ?work } UNION { ?work wdt:P674 wd:Q1621261 } .
  ?work rdfs:label ?label FILTER(CONTAINS(LCASE(?label), "spider-man"))
}

Got 1 row and 1 column:
| count       |
| ----------- |
| 3 (xsd:int) |

[Assistant]
answer

SELECT DISTINCT ?work ?workLabel WHERE {
  { wd:Q1621261 wdt:P1441 ?work } UNION { ?work wdt:P674 wd:Q1621261 } .
  ?work rdfs:label ?workLabel FILTER(CONTAINS(LCASE(?workLabel), "spider-man"))
}

Answer: There are 3 works that have Venom as a character or present and have a title containing 'Spider-Man', which likely indicates they are based on Spider-Man.

[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.

Available knowledge graphs:
- wikidata at http://localhost:7001 with prefix index for entities and similarity index for properties

Index types used for entities and properties:
- Prefix index: Retrieves items by overlap between query keywords and item words. The query keywords can match item words exactly or as prefixes.
- Similarity index: Retrieves items by cosine similarity between their embeddings and the query embedding.

Additional rules to follow:
- 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 ask the user for clarifications without first attempting to complete the task. If the task input is incomplete or ambiguous, try to make reasonable assumptions and document them.
- 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 kingdom preceded the Thonburi Kingdom ?

[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.

Available knowledge graphs:
- wikidata at http://localhost:7001 with prefix index for entities and similarity index for properties

Index types used for entities and properties:
- Prefix index: Retrieves items by overlap between query keywords and item words. The query keywords can match item words exactly or as prefixes.
- Similarity index: Retrieves items by cosine similarity between their embeddings and the query embedding.

Additional rules to follow:
- 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 ask the user for clarifications without first attempting to complete the task. If the task input is incomplete or ambiguous, try to make reasonable assumptions and document them.
- 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.

The Mongols tried to invade Japan twice, corresponding to two distinct invasion attempts in 1274 and 1281.

SPARQL query over wikidata:
SELECT COUNT(?invasion) AS ?numberOfInvasions WHERE {
  wd:Q208156 wdt:P527 ?invasion .
}

Execution result:
Error executing SPARQL query over wikidata:

[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.

Available knowledge graphs:
- wikidata at http://localhost:7001 with prefix index for entities and similarity index for properties

Index types used for entities and properties:
- Prefix index: Retrieves items by overlap between query keywords and item words. The query keywords can match item words exactly or as prefixes.
- Similarity index: Retrieves items by cosine similarity between their embeddings and the query embedding.

[Assistant]
The entity "Mongol invasions of Japan" (wd:Q208156) has parts that are specific battles or events. One of the properties is "has part(s)" (wdt:P527), which can indicate individual invasion attempts or battles.

I will now check the values for the "has part(s)" property to see how many distinct parts (invasion attempts or battles) are recorded under this entity. This will help determine how often the Mongols tried to invade Japan.

wd:Q208156

[Assistant]
The "Mongol invasions of Japan" entity has two parts listed under "has part(s)" property: the Battle of Bun'ei (wd:Q2237386) and the Battle of Kōan (wd:Q2237622). These likely correspond to two distinct invasion attempts by the Mongols.

To confirm, I will check the years or dates associated with these two battles to verify they represent two separate invasion attempts.
