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 distinct destroyers have an operator not listed in the vessel class's list of operators? For each row, include the vessel class and operator.

[Assistant]
To answer this question, I need to identify the following:
1. Entities that are destroyers.
2. The vessel class of each destroyer.
3. The operators of each destroyer.
4. The list of operators associated with the vessel class.
5. Find distinct destroyers where the operator is not in the vessel class's list of operators.
6. Return the vessel class and the operator for each such destroyer.

Step 1: Identify the property for "destroyer" as a type of vessel or ship.
Step 2: Identify the property for "operator" of a vessel.
Step 3: Identify the property for "vessel class" of a vessel.
Step 4: Identify the property for "operators" of a vessel class.

I will start by searching for the entity "destroyer" to find its Wikidata ID.

The entity "destroyer" as a warship type designed for escort duties against smaller vessels is wd:Q174736.

Next, I will search for the property "operator" related to vessels to identify the correct property for operators of vessels.

[Assistant]
The property "vessel class" (wdt:P289) is the correct property for the class of a vessel.

Next, I will search for the property that links a vessel class to its list of operators. I will try searching for "operator" in the context of a vessel class.

[Assistant]
There is no direct property linking a vessel class to a list of operators. However, the vessel class itself might have operators as entities linked by the "operator" property (wdt:P137).

I will now write a SPARQL query to find distinct destroyers (instances of or subclasses of destroyer), their vessel classes, their operators, and the operators of the vessel classes. Then I will filter to find destroyers where the operator is not in the vessel class's list of operators.

I will start with a query to get destroyers, their vessel classes, and their operators.

[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 QLever SPARQL endpoint. I will rewrite the query without using SERVICE wikibase:label and instead use optional rdfs:label for labels.

I will also remove the optional vessel class operators for now and just get destroyers, their vessel classes, and their operators.

[Assistant]
I have retrieved distinct destroyers with their vessel classes and operators. Now, I need to get the operators of the vessel classes and filter to find destroyers where the operator is not in the vessel class's list of operators.

I will write a query to get destroyers, their vessel classes, their operators, and the operators of the vessel classes, then filter to find cases where the destroyer's operator is not in the vessel class's operators. I will also include labels for readability.

Feedback (status=done):
The SPARQL query correctly identifies distinct destroyers where the operator is not listed in the vessel class's list of operators. It returns the destroyer, vessel class, and operator along with their English labels, which matches the user's request. The use of FILTER NOT EXISTS to exclude operators listed in the vessel class is appropriate. The query also respects the rule to return identifiers and optionally labels in English. The execution result shows a reasonable number of rows with relevant examples. 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.

I found 10 YouTubers who are also science communicators. The next step is to filter out those who have an image (property P18) and keep only those who do not have an image. Then, I will retrieve their YouTube channel ID (property P2397) and number of social media followers if available. Finally, I will order the results by the number of social media followers in descending order.

I will write a SPARQL query to do this.

[Assistant]
I found 13 YouTubers who are also science communicators and do not have an image. Some of them have YouTube channel IDs, but none have the number of social media followers listed.

I will now provide the final answer with the YouTubers, their YouTube channel IDs, and the number of social media followers if available, ordered by the number of followers (though none are available).

Feedback (status=done):
The SPARQL query correctly identifies humans who are both YouTubers and science communicators without an image. It retrieves their YouTube channel IDs and number of social media followers if available, and orders the results by followers in descending order. The answer clearly states the number of such YouTubers found and notes the lack of follower data, which matches the query results. The query respects the requirement to return identifiers and labels, and the explanation is clear and complete. No further refinement is necessary.

There are several role-playing video games including "Portugal Virtual," "Xeonjia," "cluster," "Lords of the Earth," and "Prahy." Some of these games have developers, publishers, and publication dates available. For example, "cluster" was developed by CLUSTAR and published on 2017-05-31. "Lords of the Earth" was published in 1983, and "Prahy" was published in 2005. Many games do not have complete information on developers or publishers in the available data.

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 items are role-playing video games? Include their developers, publishers, and publication dates, if available.

[Assistant]
To answer this question, I need to identify the entity for "role-playing video games" and then find items that are instances of or subclasses of this entity. After that, I will retrieve their developers, publishers, and publication dates if available.

Step 1: Search for the entity "role-playing video game" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. role-playing video game, also known as role playing video games, RP video game, RPVG, RPG videogame, RPG video game (wd:Q744038): video game genre
2. action role-playing game, also known as ARPG, action/RPG, action RPG, action role-playing video game, action-RPG (wd:Q1422746): subgenre of role-playing and action video games
3. gamer, also known as player, video game player, video gamer, video role-playing game player, video RPG player (wd:Q5276395): person who plays video games and/or identifies with the gamer identity
4. tactical role-playing game, also known as RSLG, simulation RPGs, SRPG, strategic roleplaying game, strategy role-playing game (wd:Q1529437): video game genre
5. Japanese role-playing video game, also known as Japanese role-playing game, JRPG (wd:Q5923834): video game genre
6. turn-based role-playing game, also known as turn-based RPG, turn-based roleplaying game, turn-based role-playing video game (wd:Q105906396): genre of roleplaying games where players take turns when playing
7. side-scrolling role-playing video game, also known as side-scrolling RPG, side-scrolling role-playing game, side-scroller RPG (wd:Q107631040): video game genre
8. Western role-playing game, also known as Western role-playing video games, Western RPG, WRPG (wd:Q61654424): video game subgenre
9. history of Western role-playing video games, also known as history of Western RPGs, Western role-playing video games history (wd:Q5867207): aspect of history
10. chronology of tactical role-playing video games (wd:Q16968506)

[Assistant]
The entity "role-playing video game" (wd:Q744038) is the main video game genre we are interested in. Now, I will write a SPARQL query to find items that are instances of this entity or its subclasses. I will also try to retrieve their developers, publishers, and publication dates if available.

I will start with a query to get items that are instances of "role-playing video game" and their developers, publishers, and publication dates.

[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 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 the items, developers, and publishers.

I will now execute the revised query.

[Tool]
Got 2 rows and 7 columns:
| game                      | gameLabel      | developer | developerLabel | publisher | publisherLabel | publicationDate |
| ------------------------- | -------------- | --------- | -------------- | --------- | -------------- | --------------- |

[Assistant]
The query returned two role-playing video games: "Xeonjia" and "Pandoland." However, no developers, publishers, or publication dates were available for these two items in the limited result set.

I will now expand the query to include subclasses of "role-playing video game" to get a broader set of role-playing video games and try to retrieve their developers, publishers, and publication dates. I will also increase the limit to 50 to get more results.

Feedback (status=done):
The SPARQL query correctly retrieves role-playing video games along with their developers, publishers, and publication dates when available. It uses appropriate properties and includes optional clauses to handle missing data gracefully. The answer provides a representative sample of games with some details, matching the query results. The query respects the requirement to return identifiers and labels and does not perform any post-processing outside SPARQL. Overall, the output is correct and complete for the user's question.

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 distinct items that have an Encyclopedia of Life ID, but are not taxons or subclasses of taxons? Include item labels and labels of what the items are instances of.

Step 4: Now I will write a SPARQL query to find distinct items that have an Encyclopedia of Life ID (wd:P830) but are not taxons (wd:Q16521) or subclasses of taxons. I will also include the labels of these items and the labels of what these items are instances of (wdt:P31).

[Tool]
SPARQL execution failed:
HTTPSConnectionPool(host='qlever.cs.uni-freiburg.de', port=443): Read timed out. (read timeout=30)

[Assistant] The query execution timed out, likely due to the complexity or size of the query. I will simplify the query by removing the optional label retrieval and limiting the results to fewer items to reduce the load. Then I will try again.

Feedback (status=retry):
The system's SPARQL query aims to find items with an Encyclopedia of Life ID that are not taxons or subclasses of taxons, including their labels and instance types. However, the query execution failed due to a timeout, so no results were obtained. Additionally, the query has some issues: it uses both FILTER NOT EXISTS with ?item wdt:P31/wdt:P279* wd:Q16521 and FILTER NOT EXISTS with ?item wdt:P279* wd:Q16521, which might be redundant or incorrect since ?item wdt:P279* wd:Q16521 checks if the item is a subclass of taxon, but items are usually instances, not subclasses. Also, the OPTIONAL clause for instanceOf labels is not correctly linked to the instanceOf variable, as it lacks a triple pattern connecting ?instanceOf to anything. The query should be refined to correctly exclude taxons and subclasses of taxons, ensure proper OPTIONAL label retrieval, and avoid timeout by possibly limiting the query or optimizing it. Therefore, a retry with a refined query is recommended.

[Assistant]
Thank you for the feedback. I understand the issues:

1. The FILTER NOT EXISTS clauses need refinement. Items are usually instances (wdt:P31), so checking if the item itself is a subclass (wdt:P279*) is likely incorrect. Instead, I should check if the item's instance (wdt:P31) is a taxon or subclass of taxon.

2. The OPTIONAL clause for instanceOf labels should properly link ?instanceOf to its label.

3. To avoid timeout, I will keep the query limited and optimize it.

I will now refine the query accordingly:
- Select items with Encyclopedia of Life ID.
- Exclude items whose instance (wdt:P31) is taxon or subclass of taxon.
- Retrieve labels for items and their instanceOf.
- Limit results to 20.

I will execute this refined query.

Feedback (status=done):
The SPARQL query correctly identifies distinct items that have an Encyclopedia of Life ID but are neither taxons nor subclasses of taxons. It properly filters out any instances or subclasses of the taxon class (wd:Q16521) and retrieves the item labels and labels of their instance types as requested. The example results provided are consistent with the query logic and the question requirements. The query also respects the rule of returning identifiers and labels without using unsupported SERVICE clauses. Overall, the output is correct and complete.
