[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:
freebase at http://galera:7002

You can use the following SPARQL prefixes implicitly in all functions:
fb: <http://rdf.freebase.com/ns/
fbkey: <http://rdf.freebase.com/key/
rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#

hint: <http://www.bigdata.com/queryHints#
wikibase: <http://wikiba.se/ontology#
qb: <http://purl.org/linked-data/cube#
void: <http://rdfs.org/ns/void#

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.

It appears there are no people in Freebase explicitly marked as being born in Marin City (fb:m.053myr). However, the description of Marin City in the search results mentioned that rapper Tupac Shakur found celebrity there in the 1990s and was associated with Marin City.

Feedback (status=refine):
The answer is mostly correct and the SPARQL query correctly retrieves the professions of Tupac Shakur, who is known to have lived in Marin City. However, the query hardcodes Tupac Shakur's identifier (fb:m.07pzc) without explicitly establishing the connection to Marin City in the SPARQL query. For completeness and robustness, the query should first find the person(s) who lived in Marin City and then retrieve their professions. This would make the answer more general and accurate, especially if there are other notable people who lived in Marin City. Please refine the query to include the connection to Marin City.

[Assistant]
Thank you for the feedback. You are correct: for completeness, the SPARQL query should not hardcode Tupac Shakur, but rather establish the relationship between Marin City and the person(s) who lived there, and then retrieve what they did (their professions).

Step-by-step plan:
1. Identify how to represent "lived in" or "residence" in Freebase—this could be "place of birth", "place of residence", or similar.
2. Use Marin City (fb:m.053myr) as the location.
3. Find all people who have a relevant property linking them to Marin City.
4. For each such person, retrieve their professions.

First, I'll search for properties related to "residence" or "lived in" for people in Freebase.

Feedback (status=refine):
The query correctly identifies persons whose place of birth is Marin City and retrieves their professions, which answers the question for the available data. However, the query only retrieves the profession(s) of the person(s) and does not attempt to retrieve other notable activities or roles (e.g., occupations, notable works, or other actions) that the person might have done, which could be relevant for a more comprehensive answer to 'what did the person do.' Additionally, the query does not retrieve labels for the IRIs, which would make the result more readable. Consider adding OPTIONAL clauses to retrieve rdfs:label for both the person and the profession, and possibly expand to other properties like occupation or notable works if available.

[Assistant]
Thank you for the feedback. To provide a more comprehensive answer, I will:

1. Retrieve not only professions but also other notable activities or roles, such as occupations and notable works, if available.
2. Add OPTIONAL clauses to retrieve rdfs:label for both the person and the activities/roles, making the results more human-readable.

Step-by-step plan:
- Use Marin City (fb:m.053myr) as the place of birth.
- For each person, retrieve:
  - Profession (fb:people.person.profession)
  - Occupation (if available, though Freebase often uses "profession")
  - Notable works (fb:common.topic.notable_for)
- Add OPTIONAL rdfs:label retrieval for person, profession, and notable work.

First, I will check if there are properties like "notable works" or "occupation" directly associated with people.

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.

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 was the movie "Shoot 'Em Up" filmed?

[Assistant]
Let's break down the question:

1. The main entity is the movie "Shoot 'Em Up".
2. The property of interest is the filming location.

First, I will search for the entity "Shoot 'Em Up" in Freebase to get its identifier.

Feedback (status=refine):
The SPARQL query is mostly correct and retrieves the filming locations for the movie 'Shoot 'Em Up' using the correct entity and property. However, the answer only mentions Toronto (fb:m.0h7h6), while the query result shows 43 rows, all with the same location but different labels in various languages. The answer should clarify that all results correspond to the same location (Toronto), and optionally mention that the labels are in different languages. The query itself could be refined to return only one row per unique location, for example by using SELECT DISTINCT or GROUP BY, to avoid duplicate entries for the same location. This would make the result clearer and more concise.

[Assistant]
Thank you for the feedback. You are correct: the query returns multiple rows for the same location (Toronto) due to labels in different languages. To improve clarity and conciseness, I will refine the query to return only one row per unique location using SELECT DISTINCT and retrieve a single (optional) label.

Here’s my plan:
- Use SELECT DISTINCT to ensure each location appears only once.
- Use GROUP BY and SAMPLE to get one label per location (since labels are in multiple languages).
- Clarify in the answer that all results correspond to the same location, Toronto, and that the labels are in different languages.

Let me write and execute the refined query.

The SPARQL query correctly retrieves the filming location(s) for the movie 'Shoot 'Em Up' by using the appropriate entity and property. It returns the actual IRI of the location and, optionally, a label. The query also avoids duplicate rows by grouping and sampling labels, which is appropriate here. The answer is accurate and complete according to the knowledge graph. No further refinement is needed.

[Assistant]
From the data:

- fb:m.04lkt8z (United Kingdom, Belgium, French Third Republic): 30,000 casualties
- fb:m.04lkt9b (Nazi Germany): 42,000 casualties (wounded)

Both of these are associated with the Battle of Dunkirk (fb:m.0jpb7), and the numbers are at or above 30,000.

Now, I will check the "Dunkirk evacuation" (fb:m.01lmvf) for casualty numbers to see if it matches the question better.

There is no direct "casualties" property for the Dunkirk evacuation (fb:m.01lmvf), but the Battle of Dunkirk (fb:m.0jpb7) has multiple casualty records, some of which are above 30,000.

Given the available data, the event in Dunkirk during WW2 with more than 30,000 estimated casualties is the Battle of Dunkirk.

I will now construct a SPARQL query that retrieves events in Dunkirk during World War II with estimated casualties greater than 30,000, showing the event and the casualty estimate.

Feedback (status=refine):
The SPARQL query correctly identifies the Battle of Dunkirk as the event in Dunkirk during WWII with more than 30,000 estimated casualties, and the answer is accurate. However, the query returns multiple rows for the same event due to different language labels, which is unnecessary unless the user specifically requested multilingual labels. To refine the query, it would be better to limit the result to a single label (e.g., English) or just return the event IRI and the casualty estimate, with the label as an optional field. This would make the output more concise and focused.

[Assistant]
Thank you for the feedback. To refine the query, I will:

- Return only the event IRI and the casualty estimate.
- Include the English label as an optional field, limiting it to English only.
- This will avoid duplicate rows for different language labels and make the result concise.

Here is the refined SPARQL query:

```sparql
SELECT DISTINCT ?event ?eventLabel ?estimate WHERE {
  fb:m.0md6f fb:location.location.events ?event .
  ?event fb:time.event.start_date ?date .
  FILTER(?date >= "1939-09-01"^^xsd:date && ?date <= "1945-09-02"^^xsd:date) .
  ?event fb:military.military_conflict.casualties ?casualty .
  ?casualty fb:military.casualties.lower_estimate ?estimateRaw .
  BIND(xsd:integer(?estimateRaw) AS ?estimate) .
  FILTER(?estimate > 30000) .
  OPTIONAL { ?event rdfs:label ?eventLabel . FILTER(LANG(?eventLabel) = "en") }
}
```

Now, I will provide this as the final answer.

Feedback (status=done):
The SPARQL query correctly identifies events in Dunkirk during World War II with more than 30,000 estimated casualties. It returns the actual IRI of the event, includes an optional label, and filters for the correct date range and casualty threshold. The answer matches the expected result for the question. No further refinement is necessary.
