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] among the other representative work of the author of hunter x hunter, which one is talking about middle school student?

[Assistant] Let's start by looking at some examples.

[Tool]
Example 1:

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.

[Assistant]
Throat singing (wd:Q1067089) has the property "has characteristic" (wdt:P1552) with the object "music tradition" (wd:Q60733114). This indicates that throat singing has the characteristic of being a music tradition.

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.

Feedback (status=done):
The SPARQL query correctly retrieves the cause of death of Julius Caesar, the author of the phrase "Alea iacta est." The query uses the appropriate entity (Julius Caesar) and property (cause of death) and returns the cause of death as "bleeding," which is accurate. The answer is complete and directly addresses the user's question. No further refinement is needed.

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 was the key event related to Salvador Dalí?

[Assistant] Let's start by looking at some examples.

[Tool]
Example 1:
Question:
List all boardgames by GMT.

SPARQL:
SELECT ?uri WHERE {
  ?uri wdt:P31 wd:Q131436 .

The examples show that for questions about key events or notable works related to a person, the property "notable work" (wdt:P800) is often used.

Step 1: Identify the entity for Salvador Dalí.
Step 2: Query the notable works or key events related to Salvador Dalí using the property wdt:P800.

I will first search for the entity Salvador Dalí in Wikidata.

[Tool]

[Assistant]
The notable works related to Salvador Dalí include "The Great Masturbator," "The Persistence of Memory," "Christ of Saint John of the Cross," "The Face of War," "The Sacrament of the Last Supper," and "Soft Construction with Boiled Beans." These can be considered key events or key works related to him.

I will now provide the final answer with these key events.

[User]
Feedback (status=refine):
The SPARQL query correctly retrieves notable works of Salvador Dalí, which are significant events related to him in the artistic context. However, the user's question is about the 'key event' related to Salvador Dalí, which might not be limited to his notable works. Key events could include important moments in his life, career milestones, or historically significant occurrences involving him. It would be better to clarify or expand the query to include other types of key events, such as significant life events (birth, death, major exhibitions, awards) or historical events linked to him. Also, the answer should clarify that these are notable works, which are one type of key event, but not necessarily the only key events. Therefore, I recommend refining the query and answer to better address the question's intent.

[Assistant]
The feedback suggests that the question about the "key event" related to Salvador Dalí could encompass more than just his notable works. It could include important life events, career milestones, major exhibitions, awards, or other historically significant occurrences involving him.

Step 1: Identify key life events and milestones related to Salvador Dalí such as birth, death, awards, and major exhibitions.
Step 2: Combine these with notable works to provide a broader view of key events.

I will first query some important life events and milestones for Salvador Dalí, such as birth (P569), death (P570), awards received (P166), and major exhibitions (P793 or related properties). Then I will combine these with the notable works (P800) in a single query.

[Assistant]
The query results include notable works, awards, and the birth and death dates of Salvador Dalí. These are indeed key events and milestones related to him.

To provide a clearer answer, I will refine the SPARQL query to label the type of event (birth, death, award, notable work) and include the date for birth and death. This will help distinguish between different types of key events.

I will now construct a refined query that returns the type of event, the event itself, and its label.

Feedback (status=refine):
The answer provides a good overview of key events related to Salvador Dalí, including his birth, death, awards, and notable works. However, the SPARQL query has some issues: it incorrectly uses a VALUES clause with string literals for event types, which is not valid. Also, the properties for birth and death (wdt:P569 and wdt:P570) are date values directly on the person entity, not linked events, so the query should retrieve these dates directly rather than treating them as events. The query should be refined to correctly retrieve birth and death dates, awards, and notable works, and to include labels for these items. Additionally, the query should avoid filtering with string literals and instead use the correct properties directly. Improving the query will ensure more accurate and complete results.

[Assistant]
The feedback points out that birth and death dates are direct properties of Salvador Dalí (wd:Q5577) and not linked events, so they should be retrieved directly. Awards and notable works are linked entities and should be retrieved with their labels. The query should be corrected to properly retrieve birth and death dates as literals and awards and notable works as linked entities with labels.

I will now refine the SPARQL query accordingly:
- Retrieve birth date (wdt:P569) and death date (wdt:P570) directly.
- Retrieve awards (wdt:P166) and notable works (wdt:P800) as linked entities with labels.
- Return all results with appropriate variable names and labels.

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.

The question asks to compare the sizes of the capitals of Iran and Germany. To answer this, I need to:

1. Identify the capitals of Iran and Germany.
2. Find the population or area (size) of these capitals.
3. Compare the sizes.

Step 1: Identify the capitals of Iran and Germany. I will search for the capitals of these countries.

[Assistant]
The population of Tehran is 8,693,706 and the population of Berlin is 3,782,202.

Since population is a common measure of size for cities, we can compare these values directly.

Tehran has a larger population than Berlin.

I will now provide the final answer with the SPARQL query used.

Feedback (status=done):
The system correctly identified the capitals of Iran and Germany as Tehran and Berlin, respectively. It retrieved their populations using the appropriate property (wdt:P1082) and compared the values accurately. The SPARQL query is well-formed, returns the required identifiers and labels, and the population values are correctly extracted and compared. The answer is complete and correctly concludes that Tehran is bigger than Berlin in terms of population. 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.

[Assistant] The property "official language" (wdt:P37) is the relevant property for official languages of the United States of America (wd:Q30). I will now write a SPARQL query to count the number of official languages for the United States of America.

[Tool]
Got 1 row and 1 column:
| count       |
| ----------- |
| 1 (xsd:int) |

[Assistant]
The query result shows that the United States of America has 1 official language according to Wikidata. However, it is known that the United States does not have an official language at the federal level, so this might be a specific designation or an error in the data.

I will now check which language is listed as the official language for the United States of America in Wikidata to better understand this result.

[Tool]
Got 1 row and 2 columns:
| language           | languageLabel |
| ------------------ | ------------- |
| English (wd:Q1860) | English (en)  |
