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 is the main subject of the manga "your lie in april": primary school, middle school or high school student?

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

[Assistant] I found 6 distinct countries where IKEA stores are located according to the data: United Kingdom, People's Republic of China, Japan, Germany, Sweden, and Turkey. However, this might not be the complete list of countries where IKEA has been established, as there could be more stores not listed or other types of establishments. I will try to find if there is a more comprehensive property or data about the countries where IKEA operates.

[Assistant] The property "operating area" (wdt:P2541) seems relevant as it indicates the geographic area or jurisdiction an organization operates in. I will check if IKEA has any values for this property to find the countries where it operates.

[Tool] Got no rows and 2 columns

[Assistant] There are no values for the property "operating area" for IKEA in Wikidata. I will try the property "location" (wdt:P276) to see if there are any locations associated with IKEA that might indicate countries where it is established.

[Tool] Got no rows and 2 columns

[Assistant] There are no values for the property "location" for IKEA either. I will now try to find all instances of IKEA stores or branches and count the distinct countries of their locations, but this time I will also consider the property "located in the administrative territorial entity" (wdt:P131) for the stores to get the countries.

[Tool] Got no rows and 2 columns

[Assistant] There are no results when using the property "located in the administrative territorial entity" (wdt:P131) for IKEA stores to get countries. I will try a more general approach to find all entities that are instances of IKEA stores or branches and have a country (wdt:P17) property, then count the distinct countries.

[Assistant] The distinct countries where IKEA stores are located according to the data are 6: United Kingdom, People's Republic of China, Japan, Germany, Sweden, and Turkey. This is the best available data on the number of countries where IKEA has been established. I will now provide the final answer.

Feedback (status=refine):
The SPARQL query counts the number of distinct countries where IKEA stores (instances of Q50399787) are located, which is a reasonable approach. However, the query assumes that all IKEA stores are correctly classified as instances of Q50399787 and that all such stores have the property P17 (country) set. There might be missing or incomplete data on Wikidata, which could affect the accuracy of the count. Additionally, the query does not explicitly link the stores to the IKEA company itself, so it might include stores not directly operated by IKEA or miss some. To improve, consider verifying that the stores are linked to IKEA as the operator or owner, or use a more direct property linking IKEA to countries where it operates. Also, it would be good to include labels for countries optionally to help verify the results. Overall, the answer is plausible but might not be fully complete or accurate due to data limitations and query scope.

[Assistant] Thank you for the feedback. To improve the query, I will try to ensure that the stores counted are directly linked to IKEA as the operator or owner. I will look for properties linking stores to IKEA (wd:Q54078) such as "owned by" or "operator" and then count the distinct countries of those stores. I will also include optional labels for the countries for better verification. I will now search for properties that link an entity to its operator or owner.

[Assistant] The property "operator" (wdt:P137) is suitable to link stores to the organization that operates them. I will now modify the query to find stores that are instances of IKEA store (wd:Q50399787) and have IKEA (wd:Q54078) as their operator, then count the distinct countries of those stores and include optional labels for the countries.

[Tool]
Got 1 row and 2 columns:
| count       | countries |
| ----------- | --------- |
| 0 (xsd:int) |           |

[Assistant] There are no IKEA stores (wd:Q50399787) with IKEA (wd:Q54078) explicitly listed as the operator (wdt:P137) in the data. This might indicate incomplete data or that the operator property is not used for these stores. I will try the property "owned by" (wdt:P127) instead to see if stores are linked to IKEA as the owner.

[Tool]
Got 1 row and 2 columns:
| count       | countries |
| ----------- | --------- |
| 0 (xsd:int) |           |

[Assistant] There are also no IKEA stores with IKEA explicitly listed as the owner (wdt:P127) in the data. It seems that the direct links between IKEA stores and the IKEA company are not present or not consistently used in Wikidata. Given this limitation, the best available approach is to count the distinct countries of entities that are instances of IKEA stores (wd:Q50399787) and have a country (wdt:P17) property, as done previously. I will provide this query again with optional country labels for clarity.

Feedback (status=done):
The SPARQL query correctly counts the distinct countries where IKEA stores (instances of Q50399787) are located using the property P17 (country). The answer '6' matches the query result and is consistent with the question about the number of countries where IKEA has been established. The query follows the rules by returning only the count and uses appropriate properties and entities. 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.

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=refine):
The answer correctly identifies 'empress' as the female form of emperor in English, supported by the Wikidata entity. However, the SPARQL query returns multiple female forms in various languages rather than specifically the English term. To improve, the query should be refined to filter for the English label or to directly retrieve the English term 'empress' to align with the user's question about the English form. This would make the answer more precise and directly relevant.

[Assistant] Thank you for the feedback. I will refine the SPARQL query to specifically retrieve the English female form of the label for "emperor" (wd:Q39018) using the property "female form of label" (wdt:P2521) with a language filter for English. This will ensure the answer is precise and directly relevant to the user's question about the English term.
