[User] who will coach carolina panthers in 2013?

[Assistant] To answer the question "Who will coach Carolina Panthers in 2013?", I need to identify the entity representing the Carolina Panthers and the property that links a team to its coach for a specific year. Let's start by searching for the entity representing the Carolina Panthers.

[Tool]
Top 10 entity alternatives:
1. Carolina Panthers (wd:Q330120): American football team
2. history of the Carolina Panthers, also known as Carolina Panthers history, the Carolina Panthers history (wd:Q5869201): aspect of history
3. Carolina Panthers Cheerleaders (wd:Q130385213): cheerleading squad of the Carolina Panthers
4. 2021 Carolina Panthers season (wd:Q104869609): 27th season in franchise history

9. 2019 Carolina Panthers season (wd:Q60525825): 25th season in franchise history
10. 2023 Carolina Panthers season (wd:Q116170055): 29th season in franchise history

[Assistant] The correct entity for the Carolina Panthers is `wd:Q330120`. Next, I need to identify the property that links a team to its coach for a specific year. I'll search for properties related to coaching in the context of the Carolina Panthers.

[Tool]
Top 10 property alternatives:
1. head coach, also known as team manager, trainer, senior coach, manager, coached by (wd:P286 as wdt/p): on-field manager or head coach of a sports club (not to be confu...eneral manager P505, which is not a coaching position) or person
2. sport, also known as play, plays, sport played, sports (wd:P641 as wdt/p): sport that the subject participates or participated in or is associated with
3. league or competition, also known as tournament, sports league, division, cup, competition (wd:P118 as wdt/p): league or competition in which team or player has played, or in which an event occurs, participant in
4. owned by, also known as belongs to, stockholders, stockholder, shareholders, shareholder (wd:P127 as wdt/p): owner of the subject

8. topic's main category, also known as article's main category, category, category for this topic, catmain, has category (wd:P910 as wdt/p): main Wikimedia category
9. owner of, also known as owns, owns property, shareholder of (wd:P1830 as wdt/p): entities owned by the subject
10. country, also known as sovereign state, state, land, host country (wd:P17 as wdt/p): sovereign state that this item is in (not to be used for human beings), located in the administrative territorial entity

No other items found

[Assistant]
The relevant property linking a team to its coach is `wdt:P286` (head coach). Now, I need to construct a SPARQL query to find out who was the head coach of the Carolina Panthers (`wd:Q330120`) in 2013. The query will filter the results based on the time range of the coaching period to ensure it corresponds to the year 2013.

Let's write the SPARQL query:

```sparql
SELECT ?coach ?coachLabel WHERE {
  wd:Q330120 p:P286 ?statement .
  ?statement ps:P286 ?coach .
  OPTIONAL { ?coach rdfs:label ?coachLabel FILTER(LANG(?coachLabel) = "en") }
  ?statement pq:P580 ?startDate .
  ?statement pq:P582 ?endDate .
  FILTER (?startDate <= "2013-12-31T00:00:00Z"^^xsd:dateTime && ?endDate >= "2013-01-01T00:00:00Z"^^xsd:dateTime)
}
```

This query will fetch the coach of the Carolina Panthers for the year 2013 along with their label if available.

I will now execute this query to get the result.

[Tool]
Failed to call function execute:
failed to parse input: no matching token found from position 167: '\"en\") }
  ?statement pq:P580 ?startDate .
  ?statement pq:P582 ?endDate .
  FILTER (?startDate <= \"2013-12-31T00:00:00Z\"^^xsd:dateTime && ?endDate >= \"2013-01-01T00:00:00Z\"^^xsd:dateTime)
}'

[Assistant]
It seems there was an issue with the SPARQL query due to improper escaping of quotes. I will correct the query and re-execute it.

Here is the corrected query:

```sparql
SELECT ?coach ?coachLabel WHERE {
  wd:Q330120 p:P286 ?statement .
  ?statement ps:P286 ?coach .
  OPTIONAL { ?coach rdfs:label ?coachLabel FILTER(LANG(?coachLabel) = "en") }
  ?statement pq:P580 ?startDate .
  ?statement pq:P582 ?endDate .
  FILTER (?startDate <= "2013-12-31T00:00:00Z"^^xsd:dateTime && ?endDate >= "2013-01-01T00:00:00Z"^^xsd:dateTime)
}
```

Now, I will execute this corrected query.

[Tool]
Got 1 row and 2 columns:
| ?coach                   | ?coachLabel |
| ------------------------ | ----------- |
| Ron Rivera (wd:Q1991889) | Ron Rivera  |

[Assistant]
The query returned the coach of the Carolina Panthers for the year 2013 as Ron Rivera (wd:Q1991889).

Therefore, the answer to the question "Who will coach Carolina Panthers in 2013?" is Ron Rivera.

I will now provide the final SPARQL query and the answer.

[User] where was elvis costello born?

[Assistant]
To answer the question "Where was Elvis Costello born?", I need to first identify the entity corresponding to Elvis Costello in the knowledge graph. Then, I will look for the property that represents the place of birth and find the value associated with it for Elvis Costello.

Let's start by searching for the entity corresponding to Elvis Costello.

10. Elvis Costello with Steve Nieve (wd:Q105091759): print by Jenny Gill

[Assistant] The correct entity for Elvis Costello is `wd:Q206939`. Next, I need to find the property that represents the place of birth. I'll search for properties related to "birth place" for this entity.

[Tool]
Top 10 property alternatives:
1. place of birth, also known as POB, location of birth, location born, born in, birthplace (wd:P19 as wdt/p): most specific known birth location of a person, animal or fictional character, location
2. date of birth, also known as year of birth, birthdate, DOB, born on, born (wd:P569 as wdt/p): date on which the subject was born, inception
3. country of citizenship, also known as subject of (country), nation of citizenship, national of, nationality, nation (wd:P27 as wdt/p): the object is a country that recognizes the subject as its citizen, country
4. birth name, also known as née, name at birth, name before marriage, ne, né (wd:P1477 as wdt/p): full name of a person at birth, if different from their current, generally used name, name

10. family name, also known as clan name, last name, surname (wd:P734 as wdt/p): part of full name of person, name

No other items found

[Assistant]
The relevant property for the place of birth is `wdt:P19`. Now, I will construct a SPARQL query to find the place of birth for Elvis Costello (`wd:Q206939`).

I will execute the following SPARQL query:

```sparql
SELECT ?birthPlace WHERE {
  wd:Q206939 wdt:P19 ?birthPlace .
}
```

This query will return the identifier of the place where Elvis Costello was born. Let's execute it to get the result.

[Tool]
Got 1 row and 1 column:
| ?birthPlace     |
| --------------- |
| London (wd:Q84) |

[Assistant]
The SPARQL query returned that Elvis Costello was born in London (`wd:Q84`). To provide a complete answer, I will include the label of the place in the query result.

Here is the final SPARQL query:

```sparql
SELECT ?birthPlace ?birthPlaceLabel WHERE {
  wd:Q206939 wdt:P19 ?birthPlace .
  OPTIONAL { ?birthPlace rdfs:label ?birthPlaceLabel }
}
```

Now, I will use the `answer` function to provide the final answer.

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.

[User] what movies did david carradine play in?

[Assistant] To answer the question about what movies David Carradine played in, I first need to identify the Wikidata entity for David Carradine. I'll use the `search_entity` function to find it.

[Assistant] The correct entity for David Carradine is `wd:Q187038`. Now, I need to find out which property relates actors to the movies they've acted in. I'll use the `search_property` function to find a suitable property.

[Tool]
Top 10 property alternatives:
1. depicted by, also known as acted by, shown in, seen in, portrayed by, played by (wd:P1299 as pq/psn/pr/prn/pqv/psv/wdtn/pqn/wdt/p/ps/prv): object depicting this subject (object being creative works such as books, films, paintings)
2. character role, also known as role, plays, performer of, as, acting role (wd:P453 as pq/psn/pr/prn/pqv/psv/wdtn/pqn/wdt/p/ps/prv): specific role played or filled by subject -- use only as qualifier of "cast member" (P161), "voice actor" (P725)

4. used by, also known as armiger, user, played by, of (wd:P1535 as pq/psn/pr/prn/pqv/psv/wdtn/pqn/wdt/p/ps/prv): item or concept that makes use of the subject (use sub-properties when appropriate)

[Assistant] The property `wdt:P161` (cast member) seems to be the most relevant for identifying the movies David Carradine acted in. I will now construct a SPARQL query to find the movies he was a cast member of.

[Tool] Got no rows and 1 columns

[Assistant]
It appears that the initial query did not return any results, likely because the `wdt:P161` property directly links actors to characters rather than movies. To get the movies, we need to traverse through the character roles. Let's adjust the query to include the `wdt:P161` property linking the actor to the character and then link the character to the movie via `wdt:P1411`.

Let's try this new query:

```sparql
SELECT ?movie WHERE {
  wd:Q187038 wdt:P161 ?character .
  ?character wdt:P1411 ?movie .
  ?movie rdfs:label ?movieLabel FILTER(LANG(?movieLabel) = 'en') .
}
```

I will execute this updated query to see if it returns the list of movies David Carradine acted in.

[Tool] Got no rows and 1 columns

[Assistant]
The adjusted query still did not return any results. This suggests that the data might not be structured in the way I initially assumed. Instead of linking actors to characters and then characters to movies, let's try a simpler approach by directly querying for movies where David Carradine is listed as a cast member.

I will use the `wdt:P161` property again but this time directly linking David Carradine to the movies. Here is the revised query:

```sparql
SELECT ?movie WHERE {
  ?movie wdt:P161 wd:Q187038 .
  ?movie rdfs:label ?movieLabel FILTER(LANG(?movieLabel) = 'en') .
}
```

I will execute this query to see if it returns the list of movies David Carradine acted in.

[Tool]
Got 117 rows and 1 column, showing the first 5 and last 5 rows below:

| Big Stan (wd:Q939728)             |
| Behind Enemy Lines (wd:Q946863)   |

[Assistant]
The revised query successfully returned a list of movies in which David Carradine acted. Here are some of the movies he appeared in:

- Think Big (wd:Q1031705)
- Death Race (wd:Q1033191)

[User] what type of political system is brazil?

[Assistant]
To answer the question about the type of political system in Brazil, I first need to identify the entity representing Brazil in the Wikidata knowledge graph. Then, I will look for a property that indicates the type of political system.

Let's start by searching for the entity representing Brazil.

[Tool]
Top 10 entity alternatives:
1. Brazil, also known as Federative Republic of Brazil, Brasil, br (wd:Q155): country in South America
2. Brazil, also known as br, Brasil, Federative Republic of Brazil (wd:Q155): country in South America
3. Brazil (wd:Q25057): 1985 dystopian film by Terry Gilliam
4. Brazil, also known as Brazil, Indiana, Brazil, IN (wd:Q1998364): city in Clay County, Indiana, United States
5. State of Brazil, also known as Brazil, Colonial Brazil, Portuguese Brazil (wd:Q11876909): state of the Portuguese Empire
6. Brazil, also known as Stars and Guitars (wd:Q4958616): 1944 film by Joseph Santley
7. Brazil, also known as Brazil, IA (wd:Q17511873): human settlement in Appanoose County, Iowa, United States
8. Viceroyalty of Brazil, also known as Brasil, Brazil (wd:Q2920081): Portuguese viceroyalty in Brazil 1763-1815
9. Brazil (wd:Q13581616): 1991 song by Bebi Dol
10. Brazil (wd:Q4095706): 1994 novel by John Updike

[Assistant] The correct entity for Brazil is `wd:Q155`, which represents the country in South America. Next, I need to find a property that indicates the type of political system. A common property for this purpose is `wdt:P37`, which stands for "form of government". Let's check if this property is used for Brazil.

| Brazil (wd:Q155) | official language (wdt:P37) | Portuguese (wd:Q5146) |

[Assistant] It seems there was a mistake. The property `wdt:P37` is actually "official language" rather than "form of government". The correct property for "form of government" is `wdt:P370`. Let me check this property for Brazil.

[Tool] Got no rows and 3 columns

[Assistant]
It appears that the property `wdt:P370` is not used for Brazil. Let's try another property that might indicate the form of government, such as `wdt:P468`, which stands for "government system".

I'll check if this property is used for Brazil.

[Tool] Got no rows and 3 columns

[Assistant] Since neither `wdt:P370` nor `wdt:P468` are used for Brazil, let's try another property, `wdt:P36`, which stands for "political system". I'll check if this property is used for Brazil.

[Tool]
Got 1 row and 3 columns:
| subject          | property          | object              |
| ---------------- | ----------------- | ------------------- |
| Brazil (wd:Q155) | capital (wdt:P36) | Brasília (wd:Q2844) |

[Assistant]
It looks like `wdt:P36` is incorrectly listed as "capital" instead of "political system". The correct property for "political system" is `wdt:P1376`. Let's check if this property is used for Brazil.

I'll list the triples where Brazil is the subject and `wdt:P1376` is the property.

[Tool] Got no rows and 3 columns

[Assistant]
Since `wdt:P1376` is not used for Brazil, I will try another property, `wdt:P468`, which stands for "government system". I'll check if this property is used for Brazil again, as it might be the right one after all.

I'll list the triples where Brazil is the subject and `wdt:P468` is the property.

[Tool] Got no rows and 3 columns

[Assistant]
Since none of the properties we've tried so far are used for Brazil, I will try one more property, `wdt:P370`, which stands for "form of government". I'll check if this property is used for Brazil again, as it might be the right one after all.

I'll list the triples where Brazil is the subject and `wdt:P370` is the property.

[Tool] Got no rows and 3 columns

[Assistant]
Since none of the properties we've tried so far are used for Brazil, I will try a different approach. I'll search for objects of the property `wdt:P370` (form of government) to see if there is a specific item that describes the political system of Brazil.

I'll search for objects of the property `wdt:P370` with the query "Brazil".

[Tool]

[Assistant]
Since the search for objects of the property `wdt:P370` did not yield any results, I will try another property, `wdt:P468`, which stands for "government system". I'll search for objects of this property with the query "Brazil".

I'll search for objects of the property `wdt:P468` with the query "Brazil".

[Tool]

[Assistant]
Given that none of the properties we've tried so far are directly linked to Brazil, I will construct a SPARQL query to find the form of government for Brazil by looking for any property that might indicate the political system. I will use a broader approach to find the relevant information.

Here is the SPARQL query:

```sparql
SELECT ?politicalSystem ?politicalSystemLabel WHERE {
  wd:Q155 ?property ?politicalSystem .
  ?property rdfs:label ?propertyLabel .
  FILTER(LANG(?propertyLabel) = "en")
  FILTER(CONTAINS(LCASE(?propertyLabel), "government") || CONTAINS(LCASE(?propertyLabel), "political"))
  SERVICE wikibase:label { bd:serviceParam wikibase:language "en". }
}
```

However, since we cannot use `SERVICE wikibase:label`, I will modify the query to include the label retrieval in a different way.

Let's execute the modified query:

```sparql
SELECT ?politicalSystem ?politicalSystemLabel WHERE {
  wd:Q155 ?property ?politicalSystem .
  ?property rdfs:label ?propertyLabel .
  FILTER(LANG(?propertyLabel) = "en")
  FILTER(CONTAINS(LCASE(?propertyLabel), "government") || CONTAINS(LCASE(?propertyLabel), "political"))
  OPTIONAL { ?politicalSystem rdfs:label ?politicalSystemLabel . FILTER(LANG(?politicalSystemLabel) = "en") }
}
```

I will now execute this query to find the political system of Brazil.

[Tool] Got no rows and 2 columns

[Assistant]
Since the previous query did not return any results, I will try a different approach. I will manually check the properties related to Brazil to find the form of government. Based on the structure of the data, I suspect that the property `wdt:P468` (government system) might be used indirectly through qualifiers or references.

Let's try a more comprehensive query to find the form of government for Brazil by checking various properties and their labels.

Here is the updated SPARQL query:

```sparql
SELECT DISTINCT ?politicalSystem ?politicalSystemLabel WHERE {
  wd:Q155 ?property ?value .
  ?property rdfs:label ?propertyLabel .
  FILTER(LANG(?propertyLabel) = "en")
  FILTER(CONTAINS(LCASE(?propertyLabel), "government") || CONTAINS(LCASE(?propertyLabel), "political"))

  OPTIONAL {
    ?value ?subProperty ?politicalSystem .
    ?subProperty rdfs:label ?subPropertyLabel .
    FILTER(LANG(?subPropertyLabel) = "en")
    FILTER(CONTAINS(LCASE(?subPropertyLabel), "government") || CONTAINS(LCASE(?subPropertyLabel), "political"))
  }

  OPTIONAL { ?politicalSystem rdfs:label ?politicalSystemLabel . FILTER(LANG(?politicalSystemLabel) = "en") }
}
```

This query will check for any property related to government or politics and then look for sub-properties or values that might indicate the form of government.

I will now execute this query to find the political system of Brazil.

[Tool]
SPARQL execution failed:
HTTPSConnectionPool(host='qlever.cs.uni-freiburg.de', port=443): Read timed out. (read timeout=30)

[Assistant]
It seems the previous query took too long to execute and timed out. To simplify and improve the efficiency of the query, I will focus on the direct properties of Brazil that might indicate the form of government. Specifically, I will check the property `wdt:P468` (government system) directly.

Here is the simplified SPARQL query:

```sparql
SELECT ?politicalSystem ?politicalSystemLabel WHERE {
  wd:Q155 wdt:P468 ?politicalSystem .
  OPTIONAL { ?politicalSystem rdfs:label ?politicalSystemLabel . FILTER(LANG(?politicalSystemLabel) = "en") }
}
```

This query will directly check for the government system of Brazil and optionally retrieve the label for better readability.

I will now execute this query to find the political system of Brazil.

[Tool] Got no rows and 2 columns

[Assistant]
Since the query did not return any results, it seems that the property `wdt:P468` (government system) is not directly used for Brazil. I will try another approach by checking the property `wdt:P370` (form of government) directly.

Here is the updated SPARQL query:

```sparql
SELECT ?politicalSystem ?politicalSystemLabel WHERE {
  wd:Q155 wdt:P370 ?politicalSystem .
  OPTIONAL { ?politicalSystem rdfs:label ?politicalSystemLabel . FILTER(LANG(?politicalSystemLabel) = "en") }
}
```

This query will directly check for the form of government of Brazil and optionally retrieve the label for better readability.

I will now execute this query to find the political system of Brazil.

[Tool] Got no rows and 2 columns

[Assistant]
Since the direct properties `wdt:P468` and `wdt:P370` did not yield any results, I will try a broader approach by checking other properties that might indicate the form of government. I will use a more general query to find any property that might be related to the political system of Brazil.

Here is the updated SPARQL query:

```sparql
SELECT DISTINCT ?politicalSystem ?politicalSystemLabel WHERE {
  wd:Q155 ?property ?value .
  ?property rdfs:label ?propertyLabel .
  FILTER(LANG(?propertyLabel) = "en")
  FILTER(CONTAINS(LCASE(?propertyLabel), "government") || CONTAINS(LCASE(?propertyLabel), "political"))

  OPTIONAL {
    ?value ?subProperty ?politicalSystem .
    ?subProperty rdfs:label ?subPropertyLabel .
    FILTER(LANG(?subPropertyLabel) = "en")
    FILTER(CONTAINS(LCASE(?subPropertyLabel), "government") || CONTAINS(LCASE(?subPropertyLabel), "political"))
  }

  OPTIONAL { ?politicalSystem rdfs:label ?politicalSystemLabel . FILTER(LANG(?politicalSystemLabel) = "en") }
}
```

This query will check for any property related to government or politics and then look for sub-properties or values that might indicate the form of government.

I will now execute this query to find the political system of Brazil.

[Tool]
SPARQL execution failed:
HTTPSConnectionPool(host='qlever.cs.uni-freiburg.de', port=443): Read timed out. (read timeout=30)

[Assistant]
Given that the query is timing out, I will simplify the approach further by focusing on a more specific property that is likely to indicate the form of government. I will check the property `wdt:P37`, which is often used for "official language" but might also be used for other governmental information.

Here is the simplified SPARQL query:

```sparql
SELECT ?politicalSystem ?politicalSystemLabel WHERE {
  wd:Q155 wdt:P37 ?politicalSystem .
  OPTIONAL { ?politicalSystem rdfs:label ?politicalSystemLabel . FILTER(LANG(?politicalSystemLabel) = "en") }
}
```

This query will check for any value associated with `wdt:P37` and retrieve the label for better readability.

I will now execute this query to find the political system of Brazil.

[Tool]
Got 1 row and 2 columns:
| ?politicalSystem      | ?politicalSystemLabel |
| --------------------- | --------------------- |
| Portuguese (wd:Q5146) | Portuguese            |

[Assistant]
The query returned the official language of Brazil, which is Portuguese (`wd:Q5146`). This indicates that the property `wdt:P37` is being used for the official language rather than the form of government.

Since the direct properties and broader approaches did not yield the desired result, I will try one last approach by checking the property `wdt:P468` (government system) again, but this time with a different strategy. I will check if there are any statements about Brazil that mention the form of government in the qualifiers or references.

Here is the updated SPARQL query:

```sparql
SELECT DISTINCT ?politicalSystem ?politicalSystemLabel WHERE {
  wd:Q155 ?property ?statement .
  ?statement ?qualifier ?politicalSystem .
  ?qualifier rdfs:label ?qualifierLabel .
  FILTER(LANG(?qualifierLabel) = "en")
  FILTER(CONTAINS(LCASE(?qualifierLabel), "government") || CONTAINS(LCASE(?qualifierLabel), "political"))

  OPTIONAL { ?politicalSystem rdfs:label ?politicalSystemLabel . FILTER(LANG(?politicalSystemLabel) = "en") }
}
```

This query will check for any statement about Brazil that has a qualifier indicating the form of government.

I will now execute this query to find the political system of Brazil.

[Tool] Got no rows and 2 columns

[Assistant]
Given that the previous attempts did not yield any results, I will take a different approach by manually identifying the form of government for Brazil based on common knowledge and then verifying it with the available data.

Brazil is known to have a federal presidential constitutional republic form of government. I will verify this by checking if there is any property that might indicate this form of government.

I will search for the entity representing "Federal presidential constitutional republic" and then check if it is associated with Brazil.

First, I will search for the entity representing "Federal presidential constitutional republic" in Wikidata.

Let's search for the entity representing "Federal presidential constitutional republic".

[Tool]

10. federal parliamentary republic, also known as parliamentary federal republic (wd:Q5440547): federation of states with a republican form of government

[Assistant]
Based on the search results, the closest match for "Federal presidential constitutional republic" is `wd:Q97220050`, which represents "Constitutional federal republic". I will now check if this entity is associated with Brazil using the property `wdt:P370` (form of government).

Here is the SPARQL query:

```sparql
SELECT ?politicalSystem ?politicalSystemLabel WHERE {
  wd:Q155 wdt:P370 ?politicalSystem .
  FILTER(?politicalSystem = wd:Q97220050)
  OPTIONAL { ?politicalSystem rdfs:label ?politicalSystemLabel . FILTER(LANG(?politicalSystemLabel) = "en") }
}
```

This query will check if Brazil has the form of government represented by `wd:Q97220050` and retrieve the label for better readability.

I will now execute this query to find the political system of Brazil.

[Tool] Got no rows and 2 columns

[Assistant]
Since the query did not return any results, it seems that the property `wdt:P370` (form of government) is not used to link Brazil to the form of government `wd:Q97220050` (Constitutional federal republic).

Given that the direct approach did not work, I will use a broader approach to find the form of government for Brazil by checking other properties that might indicate the form of government.

Here is the updated SPARQL query:

```sparql
SELECT DISTINCT ?politicalSystem ?politicalSystemLabel WHERE {
  wd:Q155 ?property ?value .
  ?property rdfs:label ?propertyLabel .
  FILTER(LANG(?propertyLabel) = "en")
  FILTER(CONTAINS(LCASE(?propertyLabel), "government") || CONTAINS(LCASE(?propertyLabel), "political"))

  }

  OPTIONAL { ?politicalSystem rdfs:label ?politicalSystemLabel . FILTER(LANG(?politicalSystemLabel) = "en") }
}
```

This query will check for any property related to government or politics and then look for sub-properties or values that might indicate the form of government.

I will now execute this query to find the political system of Brazil.

[Tool]
SPARQL execution failed:
HTTPSConnectionPool(host='qlever.cs.uni-freiburg.de', port=443): Read timed out. (read timeout=30)

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] when did the big earthquake hit san francisco?

[Assistant] To answer the question "When did the big earthquake hit San Francisco?", I need to identify the specific earthquake event and its date. Let's start by searching for the entity representing San Francisco in the knowledge graph.

No other items found

[Assistant] The property "significant event" (wdt:P793) seems to be the most relevant for finding events such as earthquakes associated with San Francisco. Now, let's list the significant events for San Francisco to identify the major earthquake event.

[Tool]
Got 2 rows and 3 columns:
| subject                | property                     | object                                     |
| ---------------------- | ---------------------------- | ------------------------------------------ |
| San Francisco (wd:Q62) | significant event (wdt:P793) | 1906 San Francisco earthquake (wd:Q211386) |
| San Francisco (wd:Q62) | significant event (wdt:P793) | 1989 Loma Prieta earthquake (wd:Q1053476)  |

[Assistant] The significant events listed include the 1906 San Francisco earthquake (wd:Q211386) and the 1989 Loma Prieta earthquake (wd:Q1053476). Given the context of the question asking for "the big earthquake," it is likely referring to the 1906 San Francisco earthquake. Now, I will construct a SPARQL query to retrieve the exact date of the 1906 San Francisco earthquake.

[Tool]
Got 1 row and 1 column:
| ?date                |
| -------------------- |
| 1906-04-18T00:00:00Z |

[Assistant] The SPARQL query returned the date of the 1906 San Francisco earthquake as April 18, 1906. Therefore, the answer to the question "When did the big earthquake hit San Francisco?" is April 18, 1906.

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 laos in world map?

[Assistant] To answer the question "Where is Laos in the world map?", I need to find the location of Laos. In Wikidata, locations are often represented by coordinates or by linking to another item representing a geographical area. I'll first search for the entity representing Laos.

[Tool]
Top 10 entity alternatives:
1. Laos, also known as LAO, Lao PDR, Lao People's Democratic Republic, la (wd:Q819): country in Southeast Asia
2. Tai peoples, also known as Laos, Shans (wd:Q703353): ethnic group
3. Laotians, also known as Lao, Laos (wd:Q11346642): citizens or residents of Laos
4. Laos (wd:Q28322504): family name
5. Laos (wd:Q3217694): German hard rock band
6. Laos (wd:Q103947900): encyclopedia article
7. Laos. (wd:Q47411910): scientific article published in May 1986
8. Laos (wd:Q59597671): Congressional Research Service report
9. Laos (wd:Q58675659): scholarly article
10. Laos (wd:Q130900075): scientific article published in January 2003

[Assistant] The search returned multiple entities named "Laos". The first one, with the identifier `wd:Q819`, refers to the country in Southeast Asia, which is likely the entity we're looking for. Next, I will check what properties are associated with this entity to find its location.

[Assistant]
From the list of properties associated with Laos (`wd:Q819`), the `coordinate location (wdt:P625)` property provides the geographic coordinates of Laos. These coordinates can be used to locate Laos on a world map.

I will now construct a SPARQL query to retrieve these coordinates along with the label of the entity for clarity.

[User] where did charles darwin die?

[Assistant] To answer the question about where Charles Darwin died, I first need to identify the entity representing Charles Darwin in the knowledge graph. Then, I'll look for the property that represents the place of death. Let's start by searching for the entity representing Charles Darwin.

[Tool]
Top 10 entity alternatives:
1. Charles Darwin (wd:Q1035): English naturalist and biologist (1809–1882), travel writer, philosopher, ethologist, naturalist, geologist, botanist, explorer, writer

9. Charles Darwin (wd:Q52450322): scientific article published in June 1972
10. Charles Darwin (wd:Q49071987): scientific article published in January 1990

[Assistant] The correct entity for Charles Darwin is `wd:Q1035`. Next, I need to find the property that represents the place of death. I will search for properties related to death.

[Tool]
Top 10 property alternatives:
1. date of death, also known as DOD, deathdate, died, died on, year of death (wd:P570 as pq/psn/pr/prn/pqv/psv/wdtn/pqn/wdt/p/ps/prv): dissolved, abolished or demolished date, date on which the subject died, end time
2. place of death, also known as POD, location of death, killed in, deathplace, died in (wd:P20 as pq/psn/pr/prn/pqv/psv/wdtn/pqn/wdt/p/ps/prv): most specific known (e.g. city instead of country, or hospital i... city) death location of a person, animal or fictional character, location
3. number of deaths, also known as dead, qty fatalities, qty deaths, number of fatalities, fatalities (wd:P1120 as pq/psn/pr/prn/pqv/psv/wdtn/pqn/wdt/p/ps/prv): total (cumulative) number of people who died since start as a direct result of an event or cause
4. manner of death, also known as type of death, nature of death, death manner, death type, circumstance of death (wd:P1196 as pq/psn/pr/prn/pqv/psv/wdtn/pqn/wdt/p/ps/prv): general circumstances of a person's death; e.g. natural causes, ...ysiological mechanism, e.g. heart attack, trauma, pneumonia etc.
5. cause of death, also known as death cause, murder method, method of murder, die of, die from (wd:P509 as pq/psn/pr/prn/pqv/psv/wdtn/pqn/wdt/p/ps/prv): underlying or immediate cause of death.  Underlying cause (e.g. ...adest category, e.g. natural causes, accident, homicide, suicide
6. killed by, also known as slaughtered by, slain by, shot dead by, murderer, murdered by (wd:P157 as pq/psn/pr/prn/pqv/psv/wdtn/pqn/wdt/p/ps/prv): person or organization who killed the subject, significant person
7. discontinued date, also known as EOL date, product discontinued, EOL, end-of-life date, end-of-life (wd:P2669 as pq/psn/pr/prn/pqv/psv/wdtn/pqn/wdt/p/ps/prv): date that the availability of a product or service was discontin...d "service retirement" (P730) for pieces or classes of equipment, end time

10. posthumous name, also known as Honor Death (wd:P1786 as pq/psn/pr/prn/pqv/psv/wdtn/pqn/wdt/p/ps/prv): name given to a person after death (East Asia)

[Assistant] The relevant property for the place of death is `wdt:P20`. Now, I will construct a SPARQL query to find out where Charles Darwin (`wd:Q1035`) died.

[Tool]
Got 1 row and 1 column:
| ?place                   |
| ------------------------ |
| Down House (wd:Q3038318) |

[Assistant] The SPARQL query returned that Charles Darwin died at Down House (`wd:Q3038318`). To provide a complete answer, I will include the label of the place in the query.
