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.

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] How many musical ensembles were formed each year, grouped by the year of their inception and sorted by year?

[Assistant]
To answer this question, I need to identify the entity for "musical ensemble" and the property that indicates the year of inception or formation. Then I will count the number of musical ensembles formed each year, group the results by the year, and sort them by year.

Step 1: Search for the entity "musical ensemble" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. musical ensemble, also known as ensemble, music ensemble (wd:Q2088357): group of people who perform instrumental and/or vocal music, with the ensemble typically known by a distinct name
2. vocal-musical ensemble, also known as musical ensemble (wd:Q29881657): musical ensemble in which both instrumentalists and singers perform

[Assistant]
The property "inception" (wdt:P571) represents the time when an entity begins to exist, which is suitable for the year of formation of a musical ensemble.

Step 3: Construct a SPARQL query to count the number of musical ensembles (wd:Q2088357) formed each year, grouped by the year of inception (wdt:P571), and sorted by year. I will extract the year from the inception date.

[Tool]
SPARQL execution failed:
Invalid SPARQL query: The expression "YEAR ( ?inception )" does not aggregate ?inception. All non-aggregated variables must be part of the GROUP BY clause.

[Assistant] The error indicates that the YEAR(?inception) expression must be included in the GROUP BY clause as a variable. I will assign it to a variable in the WHERE clause and then group by that variable. I will fix the query accordingly.

The property for father is wd:P22.

Next, I will identify the entity or property for Canadian nationality or citizenship. I will search for "Canadian" to find the relevant entity for nationality or citizenship.

[Assistant]
The entity for Canadians (citizens and nationals of Canada) is wd:Q1196645.

Now I will construct a SPARQL query to find deceased Canadian individuals (with citizenship wd:Q1196645) who have a FamilySearch person ID (wd:P2889) and have a father (wd:P22) who does not have a FamilySearch person ID. For each person, I will include their date of death (wd:P570), FamilySearch person ID, and their father.

[Tool] Got no rows and 6 columns

[Assistant]
The query returned no results, which might mean that there are no deceased Canadian individuals with a FamilySearch person ID who have a father without a FamilySearch person ID in the dataset or the query might need refinement.

I will try a slightly modified query without the label service and with optional labels to see if that helps.

[Tool] Got no rows and 6 columns

[Assistant]
The modified query also returned no results. This suggests that there might be no such deceased Canadian individuals with a FamilySearch person ID who have a father without a FamilySearch person ID in the dataset.

I will now try to check if there are any deceased Canadian individuals with a FamilySearch person ID at all, to verify if the data is present.

[Tool] Got no rows and 4 columns

[Assistant]
There are no deceased Canadian individuals with a FamilySearch person ID in the dataset. Therefore, it is not possible to find individuals who meet the full criteria of the question.

I will now provide the final answer with this explanation.

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] Which books were authored by Arthur Conan Doyle?

[Assistant] To answer the question "Which books were authored by Arthur Conan Doyle?" I will first search for the entity representing Arthur Conan Doyle in Wikidata. Then, I will identify the property that represents "author of" or "written by" to find the books he authored. Finally, I will construct a SPARQL query to retrieve the books authored by Arthur Conan Doyle.

[Assistant] The property "notable work" (wdt:P800) seems to be the most relevant property to find books authored by Arthur Conan Doyle. I will now construct a SPARQL query to retrieve the notable works of Arthur Conan Doyle (wd:Q35610) which are instances of books.

[Tool] Got no rows and 2 columns

[Assistant] The query to find notable works of Arthur Conan Doyle that are instances of books returned no results. It is possible that some of his authored books are not marked as "notable work" or the property used is different. I will try a different approach by searching for works where Arthur Conan Doyle is the author using the property "author" (wdt:P50) which is commonly used to indicate the author of a creative work.

[Tool] Got no rows and 2 columns

[Assistant] The query to find books where Arthur Conan Doyle is the author using the property "author" (wdt:P50) also returned no results. This might be due to the data not being fully linked or using different properties for authorship. I will try to find other properties related to authorship or creator for works by Arthur Conan Doyle.

No other items found

[Assistant] The property "notable work" (wdt:P800) is the main property related to works by Arthur Conan Doyle. Since the previous query for notable works that are books returned no results, I will now try to query for all notable works of Arthur Conan Doyle without filtering by instance of book to see what kind of works are listed. This might help understand if the works are categorized differently.

[Tool]
Got 2 rows and 2 columns:

| The Lost World (wd:Q785255)            | The Lost World (en)           |

[Assistant] Arthur Conan Doyle has two notable works listed: "canon of Sherlock Holmes" and "The Lost World." Both are literary works, but only "The Lost World" is explicitly a book. To provide a more comprehensive answer, I will now search for books authored by Arthur Conan Doyle using a broader approach by looking for items that are instances of books and have Arthur Conan Doyle as the author or creator. I will include both properties "author" (wdt:P50) and "creator" (wdt:P170) to cover possible variations.

[Tool] Got no rows and 2 columns

[Assistant]
The query to find books authored or created by Arthur Conan Doyle using properties "author" (wdt:P50) and "creator" (wdt:P170) returned no results. It seems that the data in Wikidata might not have direct links for all books authored by him using these properties.

Given the limited data, the best approach is to return the notable works of Arthur Conan Doyle as found earlier, which include "canon of Sherlock Holmes" and "The Lost World," both of which are literary works associated with him.

I will now finalize the answer with these notable works.

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 sovereign states, their coordinates, and their official languages?

[Assistant]

[Assistant]
The property "official language" (wdt:P37) is the relevant property for the official languages of an entity.

Now I have the following:
- Sovereign state entity: wd:Q3624078
- Coordinates property: wdt:P625
- Official language property: wdt:P37

I will now construct a SPARQL query to get the sovereign states, their coordinates, and their official languages.

[Tool]
SPARQL execution failed:
Error while executing a SERVICE request to <http://wikiba.se:80/ontology#label>: SERVICE responded with HTTP status code: 301, Moved Permanently. First 100 bytes of the response: '<html>
<head><title>301 Moved Permanently</title></head>
<body>
<center><h1>301 Moved Permanently'

[Assistant] The query failed because the SERVICE wikibase:label is not supported by the endpoint I am using. I will rewrite the query without using SERVICE wikibase:label and instead use optional clauses to get the labels for the sovereign states and official languages.

[Tool]

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 cultural heritage items located in Helsinki? Please provide their year of creation (if available), commemorated entities (if available), images (if available), and coordinates (if available), and order by item ID.

3. Query for cultural heritage items located in Helsinki.
4. Retrieve the year of creation, commemorated entities, images, and coordinates for each item if available.
5. Order the results by item ID.

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

[Assistant] The property "heritage designation" (wdt:P1435) seems to be the most relevant for identifying cultural heritage items. Next, I will query for items that have a heritage designation and are located in Helsinki (wd:Q1757). I will also try to retrieve their year of creation, commemorated entities, images, and coordinates if available, and order the results by item ID.

[Assistant]
The query failed because the SERVICE wikibase:label is not supported by the used QLever SPARQL endpoint. I will rewrite the query without using SERVICE wikibase:label and instead use optional clauses with rdfs:label to get the labels for items and commemorated entities.

I will now execute the corrected query.

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] Who are the tennis players that are citizens of only Belgium?

[Assistant]
To answer this question, I need to find entities that are tennis players and have citizenship only of Belgium.

Step 1: Identify the entity for "tennis player."
Step 2: Identify the entity for "Belgium."
Step 3: Find tennis players with citizenship of Belgium.
Step 4: Filter those who have citizenship only of Belgium (no other citizenship).

I will start by searching for the entity "tennis player."

[Assistant]
The entity for "Belgium" is wd:Q31.

Now I will find tennis players (wd:Q10833314) who have citizenship (property wdt:P27) of Belgium (wd:Q31). Then I will filter those who have only Belgium as citizenship. I will start with a query to get tennis players with Belgium citizenship.

[Assistant] I found some tennis players who have Belgium citizenship. Now I need to filter those who have only Belgium citizenship and no other citizenship. I will write a query to find tennis players with Belgium citizenship and count their citizenships to keep only those with exactly one citizenship.
