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:

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] what language is used for the uzbl software

[Assistant]
Let's break down the question:

1. The user wants to know the programming language used for the "uzbl" software.
2. First, I need to identify the entity "uzbl" in Freebase.
3. Then, I need to find the property that relates a software to its programming language.
4. Finally, I will construct a SPARQL query to retrieve the programming language(s) for uzbl.

Let's start by searching for the entity "uzbl" in Freebase.

There are several properties related to "programming language," but most are specific to certain schemas (like Planning System, SPARQL technology, Intelligent System, etc.). Since Uzbl is a web browser, the most general property might not be in these specialized schemas.

To be thorough, I'll check which properties related to programming language are actually used for the Uzbl entity. I'll search for properties of Uzbl that mention "programming language."

[Assistant]
The query results show that Osafune was located in Okayama Prefecture (fb:m.018_yp) and also associated with Okayama city (fb:m.0gp5my). The most direct administrative region is Okayama Prefecture.

Here is the final SPARQL query and answer:

Feedback (status=refine):
The answer correctly identifies that Osafune was located in Okayama Prefecture, Japan, and the SPARQL query retrieves all locations containing Osafune. However, the answer only mentions Okayama Prefecture and Japan, omitting 'Okayama' (fb:m.0gp5my), which is also returned by the query. The answer should either clarify the administrative hierarchy or list all locations from the query result. Additionally, the SPARQL query could be improved by retrieving optional labels for the locations to make the answer more readable and informative.

[Assistant]
Thank you for the feedback. To address it:

1. I will update the SPARQL query to retrieve both the IRIs and the human-readable labels for all locations that contain Osafune.
2. I will clarify the answer by listing all locations from the query result and briefly explaining the administrative hierarchy if possible.

Here is the improved SPARQL query, which retrieves both the IRIs and optional labels for all locations that contain Osafune:

```sparql
SELECT ?location ?locationLabel WHERE {
  fb:m.02lklc fb:location.location.containedby ?location .
  OPTIONAL { ?location rdfs:label ?locationLabel }
}
```

Now, I will provide the improved answer, listing all locations and their labels.

[Tool] Stopped generation process

[User]
Feedback (status=refine):
The query correctly retrieves the locations containing Osafune, and the answer provides a good summary. However, the query returns many redundant rows for each location due to multiple labels in different languages. To improve clarity and efficiency, the query should be refined to return only one label per location, preferably in English (or Japanese if English is not available). This can be done by filtering the labels using a language tag filter (e.g., FILTER(LANG(?locationLabel) = 'en') or similar). This refinement will make the result more concise and user-friendly.

[Assistant]
Thank you for the suggestion. To address the redundancy and improve clarity, I will refine the SPARQL query to return only one label per location, preferring English labels. If an English label is not available, the query will not return a label for that location, but the IRI will still be present.

I will use the FILTER(LANG(?locationLabel) = 'en') clause to select only English labels.

Here is the improved SPARQL query:

```sparql
SELECT ?location ?locationLabel WHERE {
  fb:m.02lklc fb:location.location.containedby ?location .
  OPTIONAL { ?location rdfs:label ?locationLabel .
             FILTER(LANG(?locationLabel) = 'en') }
}
```

I will now provide the improved answer and finalize.

[Assistant]
The search did not return a direct "Dune universe" entity, but it did return related entities such as "Organizations of the Dune universe" and the "Dune" novel and film. In Freebase, fictional universes are sometimes not directly represented as a single entity, but characters are often linked to the works (books, movies) they appear in.

A practical approach is to find characters associated with the "Dune" novel (fb:m.0jdh5) or the "Dune" film (fb:m.0jdgr), as these are central works in the Dune universe.

Next, I will search for properties related to "character" for the "Dune" novel entity to see how characters are linked.

Feedback (status=refine):
The query correctly retrieves the characters associated with the original 'Dune' novel using the property 'book.book.characters'. However, the user's question asks for characters in the 'Dune universe', which could encompass all books and media in the Dune franchise, not just the original novel. To improve the answer, the query should be expanded to include characters from all works in the Dune universe, not just 'Dune' (fb:m.0jdh5). This could involve querying for all books or media related to the Dune universe and aggregating their characters. Additionally, the query should optionally retrieve labels for the characters for better readability.

[Assistant]
Thank you for the feedback. I agree that the user's question refers to the broader "Dune universe," which includes all related books and media, not just the original novel. To address this, I need to:

1. Identify all works (books, films, miniseries, etc.) that are part of the Dune universe.
2. Aggregate all characters from these works.
3. Optionally, retrieve labels for the characters for readability.

Step 1: Find how works are linked to the Dune universe in Freebase. There is a property found earlier: "part of fictional universes" (fb:fictional_universe.work_of_fiction.part_of_these_fictional_universes). I will search for a "Dune" fictional universe entity.

[Assistant]
There does not appear to be a specific "Dune universe" or "Dune fictional universe" entity in Freebase. However, the property "part of fictional universes" (fb:fictional_universe.work_of_fiction.part_of_these_fictional_universes) may still be used by works that are part of a fictional universe, possibly with a generic "Dune" or "Dune series" entity.

Let me check if the original "Dune" novel (fb:m.0jdh5) is linked to any fictional universe entity via this property, which may help identify the correct universe entity.

I have now identified the "Dune" fictional universe entity as fb:m.03nwb3. I also found that multiple works (books, games, miniseries, etc.) are linked to this universe via the property fb:fictional_universe.work_of_fiction.part_of_these_fictional_universes.

The best approach is to:
- Retrieve all works that are part of the Dune universe (fb:m.03nwb3).
- For each work, retrieve their characters using the property fb:book.book.characters (where available).
- Aggregate all unique characters and optionally retrieve their labels.

Now, I will construct a SPARQL query to do this.

Feedback (status=done):
The SPARQL query correctly retrieves all characters associated with works that are part of the Dune fictional universe by traversing from works in the Dune universe to their characters. The query returns the IRIs of the characters and optionally their labels, following the guidelines. The answer is accurate and complete for the user's question.
