This query retrieves Arsenal F.C.'s championships with labels containing 'league' but excluding 'cup', and attempts to get the year of the championship event. This should provide the years Arsenal won league championships, answering when Arsenal won the league.

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:
freebase at https://qlever.cs.uni-freiburg.de/api/freebase

You can use the following SPARQL prefixes implicitly in all functions:
fb: <http://rdf.freebase.com/ns/
fbkey: <http://rdf.freebase.com/key/
rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#

wikibase: <http://wikiba.se/ontology#
qb: <http://purl.org/linked-data/cube#
void: <http://rdfs.org/ns/void#

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 season ranking object fb:m.010hf0tw shows Arsenal's rank 4 in the 2013-14 Premier League season. We need to find all such season ranking objects for Arsenal where the rank is 1 (indicating they won the league).

[Assistant]
There are no entries with rank 1 for Arsenal F.C. in the sports league season rankings in the current data. This might mean the data is incomplete or the league wins are recorded differently.

The search results do not show the English football Premier League seasons explicitly. Since the direct approach to find the league wins of Arsenal is not yielding results, I will provide a SPARQL query that attempts to find the years Arsenal won championships that might be league titles by filtering the championships with "league" or "premier" in their labels.

This query will return the championship events and their labels that might indicate league wins.

[Tool] Stopped generation process

[User]
Feedback (status=refine):
The SPARQL query retrieves championship events linked to Arsenal F.C. and filters those whose labels contain 'league' or 'premier'. However, the results returned are Football League Cup wins, which are cup competitions, not league titles. The question specifically asks for when Arsenal won the league, which refers to the top-tier league championships (e.g., English First Division or Premier League titles). The query should be refined to specifically target league championship events rather than cup competitions. This might involve filtering by the type of championship or by more precise keywords in the label such as 'First Division' or 'Premier League' and excluding cup competitions. Additionally, including the year or season of the league win explicitly would improve the answer's clarity and relevance.

[Assistant]
Thank you for the feedback. To refine the query, I will focus on championships of Arsenal F.C. that are specifically league titles. I will filter the championships by labels containing keywords like "First Division" or "Premier League" and exclude those containing "Cup" to avoid cup competitions. Additionally, I will try to extract the year or season from the label if available to provide clearer information about when Arsenal won the league.

I will now write a refined SPARQL query accordingly.

[Tool] Stopped generation process

[User]
Feedback (status=retry):
The SPARQL query attempts to find Arsenal's league championships by filtering labels containing 'First Division' or 'Premier League' and excluding 'Cup', but it returned no results. This suggests that either the labels do not match these filters exactly or the data is not structured as expected. To improve, consider broadening the filter criteria or checking other properties that might indicate league wins. Also, ensure the query returns the actual identifiers of the championship events as required. The current query does not provide any dates or years of winning, which is essential to answer 'when did Arsenal win the league?'. The query should be refined to retrieve the years or dates associated with these championship wins, possibly by exploring related properties like the year or date of the championship event.

[Assistant]
The previous query did not return results, likely because the labels do not exactly match the filter terms or the data is structured differently. To improve, I will broaden the filter criteria to include terms like "league" and exclude "cup" to avoid cup competitions. Additionally, I will try to retrieve the year or date associated with each championship event to answer when Arsenal won the league.

I will also explore if the championship events have properties indicating the year or date of the event and include those in the query results.

I will now write a refined SPARQL query accordingly.

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:
freebase at https://qlever.cs.uni-freiburg.de/api/freebase

You can use the following SPARQL prefixes implicitly in all functions:

wikibase: <http://wikiba.se/ontology#
qb: <http://purl.org/linked-data/cube#
void: <http://rdfs.org/ns/void#

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 property "Spouse (or domestic partner)" (fb:people.person.spouse_s) is the most relevant property for finding Esther's husband.

Step 3: Construct a SPARQL query to find the spouse of Esther (fb:m.02pn7) using the property fb:people.person.spouse_s. I will also include the label of the spouse for better readability.

[Assistant] The query returned two spouses for Esther (fb:m.02pn7), but their names are not included in the result. Next, I will try to get the labels (names) of these spouses by querying their names separately. I will do this by querying the names of the two spouse entities fb:m.012zbnxz and fb:m.0130wv8p.

[Tool] Got no rows and 2 columns

[Assistant] The names of the spouses fb:m.012zbnxz and fb:m.0130wv8p could not be retrieved using the property fb:type.object.name. I will try to get the label of these spouses using the rdfs:label property instead.

[Tool] Got no rows and 2 columns

[Assistant] The labels of the spouses fb:m.012zbnxz and fb:m.0130wv8p could not be retrieved using rdfs:label either. I will try to get the names of the spouses using the property fb:common.topic.name, which is another common property for names in Freebase.

[Tool] Got no rows and 2 columns

[Assistant] The names of the spouses could not be retrieved using the common name properties. Since the original query returned two spouse entities for Esther, I will provide these spouse entity IRIs as the answer to the question "Who was Esther's husband?" as the knowledge graph does not provide further name information for these entities.

Feedback (status=refine):
The SPARQL query correctly retrieves the spouse entities of Esther, but the answer lacks human-readable names or labels for these spouses, which would make the answer more informative. The query should be refined to optionally include the rdfs:label or a similar property for the spouses to provide their names if available. Additionally, the answer should mention that the knowledge graph does not provide further name information only if that is indeed the case after attempting to retrieve labels. This would improve the completeness and clarity of the answer.

[Assistant] Thank you for the feedback. I will refine the SPARQL query to optionally include the rdfs:label or fb:common.topic.name for the spouses to provide their names if available. Then I will check if names are retrieved and include them in the answer.

The refined query still did not return names for the spouses of Esther. The knowledge graph does not seem to provide human-readable names or labels for these spouse entities.

Feedback (status=refine):
The SPARQL query correctly retrieves the IRIs of Esther's spouses from the knowledge graph. However, the answer lacks human-readable names or labels for these spouses, which would make the answer more informative and user-friendly. It is recommended to extend the query to optionally retrieve the rdfs:label or another suitable property for the spouses, so the output can include their names if available. This will improve the clarity and usefulness of the answer.

[Assistant] I understand the importance of providing human-readable names or labels for the spouses to make the answer more informative and user-friendly. I will extend the query to optionally retrieve the rdfs:label or fb:type.object.name for the spouses and include these names in the answer if available.

[Assistant]
The extended query still did not return human-readable names or labels for the spouses of Esther. It appears that the knowledge graph does not provide such information for these spouse entities.

I will provide the answer mentioning the spouse entities and that no further name information is available, as this is the best possible answer given the data in the knowledge graph.

You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:
freebase at https://qlever.cs.uni-freiburg.de/api/freebase

You can use the following SPARQL prefixes implicitly in all functions:

wikibase: <http://wikiba.se/ontology#
qb: <http://purl.org/linked-data/cube#
void: <http://rdfs.org/ns/void#

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 "Education" (fb:people.person.education) seems to be the relevant property to find where Spencer Pratt went to school. I will now write a SPARQL query to get the education information for Spencer Pratt (fb:m.02z3d24).

[Tool]
Got 1 row and 2 columns:
| education    | educationLabel |
| ------------ | -------------- |

[Assistant] I found one education entity for Spencer Pratt: fb:m.0n1cn_d. However, there is no English label available for this entity in the query result. I will now query for the label of this education entity to see if it corresponds to a school or educational institution.

[Tool] Got no rows and 1 columns

[Assistant] The education entity fb:m.0n1cn_d does not have an English label in the knowledge graph. I will try to get more information about this entity by listing some of its properties and values to understand what it represents.

[Tool]
Got 4 rows and 3 columns:

[Assistant]
The education entity fb:m.0n1cn_d is of type Education and is linked to the institution "University of Southern California" (fb:m.065y4w7). This indicates that Spencer Pratt went to the University of Southern California.

I will now finalize the answer with this information.

Feedback (status=refine):
The SPARQL query correctly retrieves the awards Marilyn Monroe won by using the property fb:award.award_winner.awards_won. However, the answer only provides the Freebase IDs of the awards without any human-readable labels or names. To improve the answer's usefulness and readability, the query should be refined to also retrieve the labels or names of the awards, for example by including an OPTIONAL clause to get rdfs:label or a similar property for each award. This will make the answer more informative and user-friendly.

[Assistant] Thank you for the feedback. I will refine the SPARQL query to include the labels of the awards Marilyn Monroe won, so the answer is more human-readable and informative. I will use an OPTIONAL clause to get the English labels of the awards.

[Assistant] The awards still do not have English labels in the knowledge graph. I will try to get alternative label properties such as fb:type.object.name or fb:type.object.key for these awards.

[Tool] Got no rows and 2 columns

[Assistant] The awards do not have the property fb:type.object.name with English labels either. I will try to get any label or name for these awards without language filtering to see if there are any labels at all.

[Assistant] Only one award has a label "For her performance." in English, but it is not very descriptive. It seems the knowledge graph does not have proper human-readable labels for the awards Marilyn Monroe won. I will provide the Freebase IDs along with this label as the best possible answer.

The SPARQL query correctly retrieves the awards Marilyn Monroe won by using the property fb:award.award_winner.awards_won. However, the answer only provides Freebase IDs without any descriptive labels, which is not very informative for the user. To improve the answer, the query should be refined to also retrieve the labels (names) of the awards using rdfs:label or a similar property. This will make the answer more understandable and useful. Additionally, the answer should mention the award names rather than just their IDs.

[Assistant] Thank you for the feedback. I understand the importance of providing human-readable labels for the awards instead of just Freebase IDs. I will try a different approach to retrieve the labels by using the property fb:type.object.name without language filtering and also try rdfs:label without language filtering to maximize the chance of getting any label for the awards Marilyn Monroe won. Then I will provide the award names in the answer.

| fb:m.0m20gt1 |       |
| fb:m.0my31c4 |       |

[Assistant] The query still did not return any labels for the awards Marilyn Monroe won. It appears that the knowledge graph does not have descriptive labels for these awards. Given this limitation, I will provide the answer mentioning that the awards are identified by Freebase IDs and that no descriptive labels are available in the knowledge graph.

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You have access to the following knowledge graphs:
freebase at https://qlever.cs.uni-freiburg.de/api/freebase

You can use the following SPARQL prefixes implicitly in all functions:
fb: <http://rdf.freebase.com/ns/
fbkey: <http://rdf.freebase.com/key/
rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#

wikibase: <http://wikiba.se/ontology#
qb: <http://purl.org/linked-data/cube#
void: <http://rdfs.org/ns/void#

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 for the national anthem of a country is fb:location.country.national_anthem. I will now write a SPARQL query to get the name of the national anthem of Canada using this property.

[Tool]
Got 1 row and 2 columns:
| anthem       | anthemName |
| ------------ | ---------- |
| fb:m.0478l5c |            |

[Assistant] The national anthem of Canada is identified as fb:m.0478l5c in the knowledge graph, but it does not have an English label. I will now try to get the name of this anthem by querying its name or title property.

[Tool]
Got 6 rows and 3 columns:
| subject      | property                                                                                | object                                                                    |
