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 are the titles of the Star Wars series movies?

[Assistant]
Let's break down the question:

1. We need to identify the entity for "Star Wars series movies".
2. We need to find the property that links movies to the Star Wars series (likely "part of the series" or similar).
3. We need to retrieve the titles of those movies.

First, I'll search for the entity representing the "Star Wars" film series.

Feedback (status=refine):
The SPARQL query is mostly correct and retrieves all movies that are part of the Star Wars film series, along with their titles. However, there are a few refinements that could improve the output:

1. The query currently includes an 'untitled Star Wars film' which does not have a title. If the question is specifically about existing movie titles, you should filter out results where the title is missing.
2. The query retrieves only the value of wdt:P1476 (title), which is language-tagged. To ensure only English titles are returned, you could add a FILTER (LANG(?title) = 'en') clause.
3. The query does not guarantee ordering by episode or release date, so the list may not be in the canonical order. Consider adding an ORDER BY clause, possibly using the 'series ordinal' (P1545) or 'publication date' (P577) if available.

Suggested improvements:
- Filter out movies without a title.
- Filter for English titles if appropriate.
- Order the results by episode number or release date for clarity.

[Assistant]
Thank you for your feedback. Here’s how I’ll refine the query:

1. Filter out movies without a title by requiring ?title to be bound.
2. Filter for English titles using FILTER (LANG(?title) = 'en').
3. Order the results by episode number if available (using series ordinal, P1545), otherwise by publication date (P577).

First, I need to check if the "series ordinal" (P1545) and "publication date" (P577) properties are available for these movies. I'll look up these properties for one of the Star Wars movies.

[Assistant]
From the above, it appears that the "series ordinal" (P1545) property is not used for the Star Wars movies, but "publication date" (P577) is available and can be used for ordering. Also, the "title" property is language-tagged, so we can filter for English.

I will now write a refined SPARQL query that:
- Selects movies that are part of the Star Wars film series (wd:Q22092344)
- Requires an English title (wdt:P1476)
- Filters out movies without a title
- Orders the results by the earliest publication date

Here is the improved query.

Feedback (status=done):
The SPARQL query correctly retrieves all movies that are part of the Star Wars film series (wd:Q22092344), fetches their English titles, and orders them by release date. The query returns the IRIs of the movies as required, and the answer matches the expected list of Star Wars series movies. No further refinement is necessary.

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 the film Red Notice was released?

[Assistant]
Let's break down the question:

1. The user is asking for the release date of the film "Red Notice".
2. I need to identify the entity for "Red Notice" (the film) in Wikidata.
3. Then, I need to find the property for "release date" in Wikidata.
4. Finally, I will construct a SPARQL query to retrieve the release date for the film.

First, I will search for the entity "Red Notice" in Wikidata.

[User] When did World War II officially end?

[Assistant]
Let's break down the question:

1. The user is asking for the official end date of World War II.
2. We need to identify the entity for "World War II" and the property that represents its end date.

Step 1: Search for the entity "World War II" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. World War II, also known as 2nd World War, WWII, WW II, WW2, WW 2 (wd:Q362): 1939–1945 global conflict
2. Theatre of War, also known as World War II, World War II RTS: Theatre of War (wd:Q2631997): 2006 video game developed by 1C Company

10. Theatre of War, also known as World War II (wd:Q108371810): video game series

[Assistant]
The most relevant entity for "World War II" is wd:Q362, which refers to the 1939–1945 global conflict.

Next, we need to find the property that represents the official end date of an event. This is likely to be something like "end time" or "official end date." I will search for properties related to "end date."

[Tool]
Top 10 property alternatives:
1. dissolved, abolished or demolished date, also known as ended, publication end date, final issue, date repealed, final year (wd:P576 as pqn/psn/pq/pqv/prv/ps/wdtn/psv/pr/p/prn/wdt): point in time at which the subject (organisation, building) ceas...g equipment,  "discontinued date" (P2669) for stopping a product, end time
2. end time, also known as ends, stop time, endtime, fall date, ineffective (wd:P582 as pqn/psn/pq/pqv/prv/ps/wdtn/psv/pr/p/prn/wdt): moment when an entity ceases to exist and a statement stops being entirely valid or no longer be true, point in time
3. date of death, also known as DOD, deathdate, died, died on, year of death (wd:P570 as pqn/psn/pq/pqv/prv/ps/wdtn/psv/pr/p/prn/wdt): dissolved, abolished or demolished date, date on which the subject died, end time
4. latest date, also known as terminus ante quem, prior to, on or before this date, no later than, max date (wd:P1326 as pqn/psn/pq/pqv/prv/ps/wdtn/psv/pr/p/prn/wdt): latest possible time that something could have occurred. Use as qualifier for other date properties
5. earliest end date, also known as end date (earliest) (wd:P8554 as pqn/psn/pq/pqv/prv/ps/wdtn/psv/pr/p/prn/wdt): (qualifier) earliest date on which the statement could have begun to no longer be true, earliest date, end time
6. work period (end), also known as floruit end, floruit (end of work), flourished (end), retirement, work ends (wd:P2032 as pqn/psn/pq/pqv/prv/ps/wdtn/psv/pr/p/prn/wdt): end of period during which a person or group flourished (fl. = "floruit") in their professional activity, end time, floruit
7. date of official closure, also known as closed, official closure, date of closure, closure date, closing date (wd:P3999 as pqn/psn/pq/pqv/prv/ps/wdtn/psv/pr/p/prn/wdt): date of official closure of a building or event, end time
8. end of covered period, also known as coverage end date, covered period end (wd:P7104 as pqn/psn/pq/pqv/prv/ps/wdtn/psv/pr/p/prn/wdt): end of period covered by an archive set, a historical book, or a collection
9. end period, also known as until period (wd:P3416 as pqn/psn/pq/pqv/prv/ps/wdtn/psv/pr/p/prn/wdt): last period in which the statement is still valid (including the period-value)
10. earliest date, also known as no earlier than, terminus post quem, start date (earliest), on or after this date, minimum date (wd:P1319 as pqn/psn/pq/pqv/prv/ps/wdtn/psv/pr/p/prn/wdt): earliest date at which an event could have happened. Use as qualifier for other date properties

[Assistant]
The most relevant properties for the end date of World War II are:
- "end time" (wd:P582)
- "dissolved, abolished or demolished date" (wd:P576), but this is more for organizations or buildings.

For a historical event like World War II, "end time" (wd:P582) is the most appropriate property.

Now, I will construct a SPARQL query to retrieve the end time (wd:P582) of World War II (wd:Q362), and optionally its label.

[User] What is the Fujiyama made of?

[Assistant]
Let's break down the question:

1. The user is asking about "Fujiyama," which is likely referring to Mount Fuji, a famous mountain in Japan.
2. The question is about what it is "made of," which suggests we are looking for its composition, likely geological (e.g., rock type, material).

Step 1: Identify the entity "Fujiyama" in Wikidata.
Step 2: Identify properties related to composition or material.
Step 3: Construct a query to retrieve the composition/material of Mount Fuji.

First, let's search for the entity "Fujiyama" in Wikidata.

[Assistant]
The most relevant entity for "Fujiyama" in the context of what it is made of is Mount Fuji (wd:Q39231), a volcano in Japan.

Next, I need to find the property in Wikidata that relates to what something is "made of" or its "composition." Common properties for this are "material used" or "composition."

I'll search for properties related to "composition" and "material."

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.
