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.

[User] What are the professions of John Lennon’s sons?

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

[Tool]
Example 1:
Question:
Who killed John Lennon?

SPARQL:
SELECT DISTINCT ?uri WHERE {
  wd:Q1203 wdt:P157 ?uri .
}

Using entities:
John Lennon, also known as John Winston Ono Lennon, John Ono Lennon (wd:Q1203): British musician (1940–1980), political activist, singer-songwriter, recording artist, record producer, peace activist, public figure, film director, film producer, prose writer, film actor, guitarist, composer, painter, pianist, singer, writer, actor, poet

Using properties:
killed by, also known as slaughtered by, slain by, shot dead by, murderer, murdered by (wd:P157 as wdt): person or organization who killed the subject, significant person

Example 2:
Question:
List the children of Margaret Thatcher.

SPARQL:
SELECT DISTINCT ?uri WHERE {
  wd:Q7416 wdt:P40 ?uri .
}

Using entities:
Margaret Thatcher, also known as Margaret Hilda Thatcher, Margaret Roberts, Margaret Hilda Roberts, Mrs. T, Mrs. Thatcher (wd:Q7416): British stateswoman and prime minister (1925–2013), research scientist, business executive, autobiographer, statesperson, politician, barrister, chemist

Using properties:
child, also known as has son, kids, mother of, kid, issue (wd:P40 as wdt): subject has object as child. Do not use for stepchildren—use "relative" (P1038), qualified with "type of kinship" (P1039), significant person, relative

Example 3:
Question:
In which studio did the Beatles record their first album?

SPARQL:
SELECT DISTINCT ?uri WHERE {
  ?album wdt:P31 wd:Q482994 ; wdt:P175 wd:Q1299 ; wdt:P577 ?date ; wdt:P483 ?uri .
}
ORDER BY ?date
LIMIT 1

Using entities:
The Beatles, also known as Fab Four, The Lads from Liverpool, John, Paul, George, and Ringo (wd:Q1299): English pop rock band (1960–1970)
album, also known as full album, record album, music album, full-length album, audio album (wd:Q482994): grouping of album releases by an artist usually released at the ...racks but in different formats for consumption (digital, CD, LP)

Using properties:

publication date, also known as launched, published, publication time, publication, pubdate (wd:P577 as wdt): date or point in time when a work was first published or released, point in time

[Assistant]
From the examples, we see that to find the sons of John Lennon, we can use the property "child" (wdt:P40) on John Lennon (wd:Q1203). Then, to find the professions of these sons, we can use the property "occupation" (wdt:P106) on the sons.

Next, I will search for John Lennon's sons using the property "child" (wdt:P40).

[Assistant] John Lennon has four sons listed: John Ono Lennon, John Lennon III, Sean Lennon, and Julian Lennon. Now, I will find the professions (occupations) of these sons using the property "occupation" (wdt:P106).

[Assistant]
John Lennon's sons and their professions are as follows:
- Sean Lennon: singer, screenwriter, actor, poet, guitarist
- Julian Lennon: singer, photographer, poet, recording artist, guitarist

The other two sons, John Ono Lennon and John Lennon III, do not have listed professions in the results.

I will now provide the final answer with this information.

Feedback (status=retry):
The system attempted to retrieve the professions of John Lennon's sons by querying their occupations in Wikidata. However, the SPARQL query failed to execute due to a timeout, likely because it included stillborn sons who do not have occupations, which may have complicated the query. Additionally, the query used a VALUES clause with four sons, including two stillborn sons, which is unnecessary since they do not have professions. To improve, the query should focus only on the living sons (Sean Lennon and Julian Lennon) who have occupations listed. Also, the query should ensure it returns only the identifiers (IRIs) and optionally labels in a way that does not cause timeouts. The system should retry with a refined query that excludes the stillborn sons and optimizes the OPTIONAL clauses to avoid timeouts.

[Assistant] Thank you for the feedback. I will refine the query to focus only on the living sons of John Lennon who have occupations listed, specifically Sean Lennon and Julian Lennon. I will also optimize the query to avoid timeouts by removing unnecessary OPTIONAL clauses and focusing on these two sons only.

Feedback (status=done):
The SPARQL query correctly retrieves the professions (occupations) of John Lennon's sons, Sean Lennon and Julian Lennon, by using their Wikidata identifiers and the occupation property. The query returns the IRIs and English labels for both the sons and their occupations, which aligns with the user's question. The answer is complete and accurate based on the query results. 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.

[User] In which stadium do the New York Yankees play?

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

[Tool]
Example 1:
Question:
Where do the Red Sox play?

[User] How many people did Oscar Pistorius kill?

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

[Tool]
Example 1:
Question:
Who killed Caesar?

SPARQL:
SELECT DISTINCT ?o1 WHERE {
  wd:Q1048 wdt:P157 ?o1 .
}

Using entities:
Julius Caesar, also known as Divine Julius (wd:Q1048): Roman general and dictator (100 – 44 BC), ancient Roman military personnel, Ancient Roman politician, Ancient Roman historian, Ancient Roman priest, military leader, politician, historian, memoirist, writer, orator, ruler, poet

Using properties:
killed by, also known as slaughtered by, slain by, shot dead by, murderer, murdered by (wd:P157 as wdt): person or organization who killed the subject, significant person

[Assistant] The property "killed by" (wdt:P157) is used to indicate the person who killed someone. To find how many people Oscar Pistorius killed, we need to find entities where Oscar Pistorius is the killer. Let's search for Oscar Pistorius entity first.

[Tool]
Top 10 entity alternatives:
1. Oscar Pistorius, also known as Oscar Leonard Carl Pistorius, Fastest man on no legs, Blade Runner (wd:Q201377): South African sprinter and convicted murderer (born 1986), athletics competitor, murderer
2. trial of Oscar Pistorius, also known as The State v Oscar Pistorius (wd:Q16328520): adjudication of murder and gun charges brought against athlete Oscar Pistorius in 2014
3. Oscar Pistorius: Blade Runner Killer (wd:Q55698496): 2017 television film

8. Oscar, also known as Oscar dos Santos Emboaba Junior, Oscar dos Santos Emboaba Júnior (wd:Q19497): Brazilian association football player (born 1991), association football player
9. Astronotus ocellatus, also known as marble cichlid, oscar, Oscar (fish), tiger oscar, velvet cichlid (wd:Q3442): species of fish from the cichlid family
10. Nakajima Ki-43 Hayabusa, also known as Oscar, Ki-43, Hayabusa, Army Zero, Army Type 1 Fighter (wd:Q700703): Japanese fighter aircraft

[Assistant] Oscar Pistorius is wd:Q201377 in Wikidata. Now, I need to find the property that indicates the people he killed. The property "killed by" (wdt:P157) indicates who killed a person, but we need the inverse relation or a property that indicates the people killed by a person. Let's search for properties related to "kill" or "murder" to find the appropriate property.

[Assistant] The property "number of victims of killer" (wdt:P1345) indicates the number of people killed by the subject. This seems to be the most direct property to answer the question. I will now query the number of victims of killer for Oscar Pistorius (wd:Q201377).

[Tool] Got no rows and 1 columns

[Assistant] There is no direct value for the number of victims of killer (wdt:P1345) for Oscar Pistorius in Wikidata. Let's try to find people who have Oscar Pistorius as the killer using the property "killed by" (wdt:P157) to count how many people he killed.

Feedback (status=done):
The SPARQL query correctly counts the number of people killed by Oscar Pistorius by using the property 'killed by' (wdt:P157) with Oscar Pistorius as the object. The query returns 1, which matches the known fact that Oscar Pistorius killed one person. The query follows the rules by returning the count as a variable and does not include unnecessary labels or computations. The answer is accurate and complete based on the data from Wikidata.

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] How many different occupations did/do spouses of winners of the Nobel Prize in Literature hold?

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

[Tool]
Example 1:
Question:
Give me all writers that won the Nobel Prize in literature.

SPARQL:
SELECT ?uri WHERE {
  ?uri wdt:P106 wd:Q36180 .
  ?uri wdt:P166 wd:Q37922 .
}

Using entities:
writer, also known as penwoman, writers, penwomen, penmen, penman (wd:Q36180): person who uses written words to communicate ideas and to produce literary works
Nobel Prize in Literature, also known as Nobel Literature Prize (wd:Q37922): one of five prizes established by Alfred Nobel

Using properties:
occupation, also known as job, work, vocation, profession, employment (wd:P106 as wdt): occupation of a person; see also "field of work" (Property:P101), "position held" (Property:P39)
award received, also known as win, winner of, recognition title, received award, prize received (wd:P166 as wdt): award or recognition received by a person, organization or creative work

Example 2:
Question:
Give me all writers that won the Nobel Prize in literature.

SPARQL:
SELECT DISTINCT ?uri WHERE {
  ?uri wdt:P106 wd:Q36180 ; wdt:P166 wd:Q37922 .
}

Using entities:
writer, also known as penwoman, writers, penwomen, penmen, penman (wd:Q36180): person who uses written words to communicate ideas and to produce literary works
Nobel Prize in Literature, also known as Nobel Literature Prize (wd:Q37922): one of five prizes established by Alfred Nobel

Using properties:
occupation, also known as job, work, vocation, profession, employment (wd:P106 as wdt): occupation of a person; see also "field of work" (Property:P101), "position held" (Property:P39)
award received, also known as win, winner of, recognition title, received award, prize received (wd:P166 as wdt): award or recognition received by a person, organization or creative work

Example 3:
Question:
Which poet wrote the most books?

SPARQL:
SELECT DISTINCT ?s1 ( COUNT( ?s2 ) as ?c ) WHERE {
  ?s1 wdt:P106 wd:Q49757 .
  ?s2 wdt:P50 ?s1 .
  ?s2 wdt:P31 wd:Q571 .
}
GROUP BY ?s1
ORDER BY DESC ( COUNT( ?s2 ) )
OFFSET 0
LIMIT 1

Using entities:
poet, also known as bard, poetry writer, poetry author, poetess (wd:Q49757): person who writes poetry
book, also known as books (wd:Q571): medium for recording information (words or images) typically on bound pages or more abstractly in electronic or audio form

Using properties:
occupation, also known as job, work, vocation, profession, employment (wd:P106 as wdt): occupation of a person; see also "field of work" (Property:P101), "position held" (Property:P39)
instance of, also known as unitary element of class, has type, unique individual of, type, item of type (wd:P31 as wdt): that class of which this subject is a particular example and mem...is a subclass of mountain (and an instance of volcanic landform)
author, also known as writer, written by, poet, playwright, maker (wd:P50 as wdt): main creator(s) of a written work (use on works, not humans); us...hor name string) when Wikidata item is unknown or does not exist, creator

[Assistant]
From the examples, we see that the Nobel Prize in Literature is wd:Q37922 and the property for award received is wdt:P166. The property for spouse is wdt:P26 and the property for occupation is wdt:P106.

The question asks for the number of different occupations held by spouses of Nobel Prize in Literature winners. So the plan is:
1. Find all winners of the Nobel Prize in Literature.
2. Find their spouses.
3. Find the occupations of these spouses.
4. Count the distinct occupations.

I will now construct a SPARQL query to get the count of distinct occupations of spouses of Nobel Prize in Literature winners.

Feedback (status=done):
The SPARQL query correctly identifies winners of the Nobel Prize in Literature, retrieves their spouses, and counts the distinct occupations of those spouses. The query uses appropriate properties (award received, spouse, occupation) and returns the count as requested. The answer is clear and directly addresses the question. No further refinement is necessary.
