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 mountains with an elevation above sea level greater than 8000 meters, excluding those located on any astronomical body?

[Assistant]
Let's break down the question:

1. We are looking for mountains (entities that are mountains).
2. Their elevation above sea level should be greater than 8000 meters.
3. Exclude those located on any astronomical body (so only those on Earth).

First, I need to identify:
- The entity for "mountain".
- The property for "elevation above sea level".
- The property for "located on astronomical body" and the entity for "Earth".

Now, let's summarize:
- Mountains: wd:Q8502
- Elevation above sea level: wdt:P2044
- Located on astronomical body: wdt:P376
- Earth: wd:Q2

We want all mountains (wd:Q8502) with elevation above sea level (wdt:P2044) > 8000, and either:
- Not having a "located on astronomical body" property, or
- Having "located on astronomical body" = wd:Q2 (Earth).

Let's construct the SPARQL query accordingly.

Feedback (status=refine):
The query is mostly correct in its logic, but there is a significant issue: it returns mountains with elevations as low as 8002 meters, which is not correct since the question asks for mountains with elevation strictly greater than 8000 meters. The FILTER(?elevation > 8000) is correct, but the data returned suggests that the elevation values in Wikidata may sometimes be in feet or other units, or there may be data inconsistencies. It would be prudent to ensure that the elevation values are in meters by checking the unit (P2044 has a unit qualifier P518). Additionally, the query should explicitly exclude mountains located on any astronomical body other than Earth, but the current logic allows mountains with no P376 value (i.e., not explicitly stated as being on Earth) to be included. To be more precise, only include mountains where P376 is either not present or explicitly Earth (wd:Q2), but ideally, prefer those with P376=Earth or with no P376 at all, and consider possible data incompleteness. Also, the query should not return mountains with ambiguous or missing elevation units. Refinement is needed to ensure only mountains above 8000 meters (in meters) on Earth are included.

[Assistant]
Thank you for the detailed feedback. Here’s how I’ll refine the approach:

**Issues to address:**
1. Some elevation values may not be in meters, so we must check the unit (P2044 with qualifier P518).
2. Only include mountains where P376 is either not present or explicitly Earth (wd:Q2), but avoid those with ambiguous or missing P376.
3. Only include mountains with elevation strictly greater than 8000 meters (in meters).
4. Exclude mountains with ambiguous or missing elevation units.

**Step-by-step plan:**
- Use the statement property (p:P2044) to access the elevation statement, then get the value (psv:P2044) and the unit (wikibase:quantityUnit).
- Only include mountains where the elevation unit is meter (wd:Q11573).
- Only include mountains where P376 is either not present or explicitly Earth (wd:Q2).
- Only include mountains with elevation > 8000 meters.

Let’s first check how elevation with unit is modeled for a known mountain, e.g., Mount Everest.

From the previous exploration, the unit for meters is wd:Q11573 and is stored as wikibase:quantityUnit on the value node of the elevation statement.

Now, let's put it all together:
- For each mountain (wd:Q8502), get the elevation statement (p:P2044), then the value (psv:P2044), amount (wikibase:quantityAmount), and unit (wikibase:quantityUnit).
- Only include if the unit is meter (wd:Q11573) and amount > 8000.
- Only include if P376 is not present or is wd:Q2 (Earth).
- Get the English label if available.

Here is the refined SPARQL query:

Feedback (status=done):
The SPARQL query correctly retrieves all mountains with an elevation above 8000 meters, ensures the elevation is measured in meters, and excludes those not located on Earth or with unspecified astronomical body. It returns the required identifiers and optionally includes English labels. The query is well-structured and meets all requirements stated in the user question and the feedback guidelines.

However, there are still no results for men's singles tennis events without a winner that are part of such tournaments. This indicates that either such events do not exist in Wikidata, or the relevant tournament-circuit relationships are not modeled in a way that can be queried. The best possible SPARQL query is included below, but it returns no results.

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]
None of the top results directly refer to a property for "circuit" in the context of a tennis tournament. However, based on previous results, the property "league or competition" (wd:P118) is often used for both tournaments and circuits in sports data modeling on Wikidata.

So, to find events that are part of a tournament that belongs to either the ATP Tour (wd:Q300008) or the Grand Prix tennis circuit (wd:Q3775082), we can use wd:P118 recursively or check if the tournament itself is an instance of or part of these circuits.

Now, let's summarize the plan for the SPARQL query:
- Find tennis events (instances of "men's singles" or subclass).
- The event is part of a tournament (wd:P118).
- The tournament is part of either ATP Tour or Grand Prix tennis circuit (wd:P118).
- The event does not have a winner (no wd:P1346).
- Return the event, and optionally its label.

Let's check if events use wd:P118 to point to tournaments, and if tournaments use wd:P118 to point to circuits like ATP Tour. I'll list some triples with property wd:P118.

[Assistant]
The property wd:P118 ("league or competition") is used to link players or events to their respective leagues or tournaments. This supports our plan to use it for both event-to-tournament and tournament-to-circuit relationships.

Now, let's check if "men's singles" events are modeled as instances of wd:Q16893072 or as subclasses. I'll list some instances of wd:Q16893072.

[Tool] Got no rows and 3 columns

[Assistant]
There are no direct instances of "men's singles" (wd:Q16893072) as a class. This suggests that specific event items (like "2011 Dubai Tennis Championships – men's singles") may not be typed as instances of wd:Q16893072, but may be linked via other properties or subclass relationships.

Let's try listing instances of "tennis event" to see how specific men's singles events are modeled. I'll search for the entity "tennis event" and then list its instances.

[Assistant]
Many specific events (e.g., "2011 Wimbledon Championships – men's singles") are instances of "tennis event" (wd:Q46190676). The event label and/or other properties likely indicate if it is a men's singles event.

To focus on men's singles, let's check if there is a property indicating the "discipline" or "gender" for these events. I'll search for properties related to "discipline" and "gender" for tennis events.

[Tool]
Top 10 property alternatives:
1. sport, also known as play, plays, sport played, sports (wd:P641 as wdt/p): sport that the subject participates or participated in or is associated with
2. has characteristic, also known as has quality, inherent property, object has characteristic, parameter, quality (wd:P1552 as wdt/p): inherent or distinguishing quality or feature of the entity. Use a more specific property when possible
3. subclass of, also known as rdfs:subClassOf, sort of, subcategory of, subgenre of, subtype of (wd:P279 as wdt/p): this item is a subclass (subset) of that item; ALL instances of ...stance of volcanic landform); Everest is an instance of mountain
4. part of, also known as of, within, system of, subsystem of, subgroup of (wd:P361 as wdt/p): object of which the subject is a part (if this subject is alread... of "has part" (P527, see also "has parts of the class" (P2670))
5. has part(s) of the class, also known as has part of class, nwere akụkụ(s) na-akpụ subclass nke, part of class, nwere akụkụ nke klaasị, part of the class (wd:P2670 as wdt/p): the subject has one or more parts of the object class, has part(s)
6. topic's main template, also known as topic has template, topic's main module, topic's main infobox, topic infobox, main template (wd:P1424 as wdt/p): the main template relating to a topic
7. properties for this type, also known as uses properties, Wikidata properties for this type, Wikidata properties for this class, uses property, things one could say about (wd:P1963 as wdt/p): when this subject is used as object of “instance of”, the following properties normally apply

No other items found

[Assistant]
There is no direct "discipline" property, but the "sport" property (wd:P641) is available, which would be "tennis" for all these events. The event label itself (e.g., "men's singles") is likely the best way to filter for men's singles events.

Now, let's summarize the query plan:
- Find instances of "tennis event" (wd:Q46190676).
- Filter for events whose label contains "men's singles".
- The event is part of a tournament (wdt:P118).
- The tournament is part of either ATP Tour (wd:Q300008) or Grand Prix tennis circuit (wd:Q3775082) (using wdt:P118).
- The event does not have a winner (no wdt:P1346).

Let's write a SPARQL query to implement this logic.

[Tool] Got no rows and 4 columns

[Assistant]
The query returned no results. This could be due to several reasons:
- The label filter for "men's singles" may not match the actual labels (e.g., different punctuation, capitalization, or language).
- The property chain for tournaments and circuits may not be modeled as expected.
- The winner property may not be present even for completed events.

Let's relax the label filter and check for events whose label contains "men" and "singles" (case-insensitive, any order). Also, let's check if tournaments are directly instances of ATP Tour or Grand Prix tennis circuit, instead of using wdt:P118.

I'll adjust the query accordingly.

[Tool] Got no rows and 4 columns

[Assistant]
Still no results. This suggests that either:
- The tournament's instance-of (wdt:P31) property is not set to ATP Tour or Grand Prix tennis circuit.
- The circuit relationship is modeled differently, or the winner property is not used as expected.

Let's try a broader approach:
- Remove the tournament circuit filter for now, and just list men's singles tennis events without a winner and their tournaments.
- This will help us inspect the data and see how tournaments are linked to circuits.

I'll run a query for men's singles tennis events (by label) without a winner, and include their tournaments.

[Tool] Got no rows and 4 columns

[Assistant]
Even with the circuit filter removed, there are no results for men's singles tennis events without a winner. This suggests that:
- Either all such events have a winner indicated, or
- The winner property is not used, or
- The modeling of these events in Wikidata is inconsistent or incomplete.

To further investigate, let's check if any tennis events at all lack a winner, regardless of gender or discipline. I'll run a query for any tennis event (wd:Q46190676) without a winner.

[Assistant]
There are tennis events without a winner indicated, and some are "singles" events. Now, let's check if any of these "singles" events are "men's singles" and if their tournaments are part of the ATP Tour or Grand Prix tennis circuit.

I'll focus on events whose label contains "men" and "singles", and for those, I'll retrieve their tournaments and the tournaments' properties to see if they are linked to ATP Tour or Grand Prix tennis circuit.

[Tool] Got no rows and 5 columns

[Assistant]
Despite several approaches, there are no results for men's singles tennis events without a winner in Wikidata, even though some "singles" events without a winner exist. This suggests that:
- Either all men's singles events in ATP Tour or Grand Prix tennis circuit have a winner indicated, or
- The relevant events are not modeled or labeled as expected in Wikidata, or
- The linkage between events, tournaments, and circuits is incomplete or inconsistent.

Given these findings, I cannot provide a satisfactory SPARQL query that returns the requested results. Here is my best attempt and an explanation.

[Tool] Stopped generation process

[User]
Feedback (status=refine):
The SPARQL query is a good attempt, but it is missing a crucial filter: it does not restrict the tournaments (?tournament) to those that are part of either the ATP Tour or the Grand Prix tennis circuit. Currently, it retrieves all men's singles tennis events without a winner, regardless of the tournament's affiliation. To refine the query, you should add a clause that ensures ?tournament is either an instance of or part of the ATP Tour (wd:Q131120) or the Grand Prix tennis circuit (wd:Q615364). This can be done by adding a FILTER or UNION block to check for these affiliations. Additionally, consider using more robust ways to identify men's singles events (e.g., via properties or more precise labels) if available.

[Assistant]
Thank you for the feedback. Let's refine the approach step by step:

1. We need to ensure that the tournament (?tournament) is either an instance of or part of the ATP Tour (wd:Q131120) or the Grand Prix tennis circuit (wd:Q615364).
2. We should robustly identify men's singles events, ideally via properties, but if not available, via label matching.
3. We still want events without a winner (no wdt:P1346).

First, let's verify the correct entities for "ATP Tour" and "Grand Prix tennis circuit" as per your feedback:
- ATP Tour: wd:Q131120
- Grand Prix tennis circuit: wd:Q615364

Now, let's check if tournaments are linked to these circuits via "instance of" (wdt:P31) or "part of" (wdt:P361).

I'll search for properties of a known tournament to see if "part of" (P361) or "instance of" (P31) is used for circuit affiliation. Let's try with "Wimbledon Championships" (wd:Q41520).

| Wimbledon Championships (wd:Q41520) | part of (wdt:P361) | Grand Slam of tennis (wd:Q102113) |

[Assistant]
"Wimbledon Championships" uses "part of" (wdt:P361) to indicate it is part of the "Grand Slam of tennis" (wd:Q102113), not directly the ATP Tour or Grand Prix tennis circuit. This suggests that for some tournaments, the circuit affiliation may be indirect or not present.

Let's check if any tournament is directly an instance of (wdt:P31) or part of (wdt:P361) ATP Tour (wd:Q131120) or Grand Prix tennis circuit (wd:Q615364). I'll search for tournaments that are instances of or part of these circuits.

[Tool] Got no rows and 2 columns

[Assistant]
No tournaments are directly modeled as instance of or part of ATP Tour (wd:Q131120) or Grand Prix tennis circuit (wd:Q615364) in Wikidata. This suggests that the circuit affiliation is either not present, modeled differently, or only present for certain years or editions.

Given this, the best way to filter is to check if the tournament's "part of" (wdt:P361) chain eventually leads to ATP Tour or Grand Prix tennis circuit, or to check for tournaments whose label contains "ATP" or "Grand Prix" as a fallback.

Let's try a query that:
- Finds men's singles tennis events (by label).
- The event is part of a tournament.
- The tournament or any of its "part of" ancestors is ATP Tour or Grand Prix tennis circuit.
- The event does not have a winner.

I'll use a property path for "part of" (wdt:P361*) to check ancestors.

[Tool] Got no rows and 4 columns

[Assistant]
Even with the recursive "part of" property path, there are no results. This strongly suggests that tournaments in Wikidata are not systematically linked to ATP Tour or Grand Prix tennis circuit via "instance of" or "part of" relationships.

Given this, the only remaining fallback is to use the tournament label to filter for those likely to be part of the ATP Tour or Grand Prix tennis circuit. This is less robust, but may yield some results.

Let's try a query that:
- Finds men's singles tennis events (by label).
- The event is part of a tournament.
- The tournament label contains "ATP" or "Grand Prix".
- The event does not have a winner.

This is not perfect, but it is the best possible approach given the current data structure.

[User]
Feedback (status=refine):
The query is well-structured and follows the user's requirements closely, including proper use of filters for event type, label, tournament affiliation, and the absence of a winner. However, the approach of filtering tournaments by label (using CONTAINS on 'atp' or 'grand prix') is not robust and may miss relevant tournaments that are linked to the ATP Tour or Grand Prix tennis circuit via explicit Wikidata items (e.g., via properties like 'part of' or 'instance of').

Instead of relying solely on label matching, the query should attempt to match tournaments that are explicitly linked to the ATP Tour (wd:Q19317) or Grand Prix tennis circuit (wd:Q615083) using relevant properties. This would make the query more accurate and less dependent on English labels. Please refine the query to use these item identifiers where possible.

[Assistant]
Thank you for the feedback. Let's refine the approach using the explicit Wikidata items for the circuits:

- ATP Tour: wd:Q19317
- Grand Prix tennis circuit: wd:Q615083

We want to find tournaments that are either:
- instance of (wdt:P31) ATP Tour or Grand Prix tennis circuit, or
- part of (wdt:P361) ATP Tour or Grand Prix tennis circuit (including recursive "part of" relationships).

We will then find men's singles tennis events (by label) that are part of these tournaments, and that do not have a winner.

Here is the refined SPARQL query:

```sparql
SELECT ?event ?eventLabel ?tournament ?tournamentLabel WHERE {
  ?event wdt:P31 wd:Q46190676.
  ?event rdfs:label ?eventLabel.
  FILTER(LANG(?eventLabel) = "en")
  FILTER(CONTAINS(LCASE(?eventLabel), "men") && CONTAINS(LCASE(?eventLabel), "singles"))
  ?event wdt:P118 ?tournament.
  OPTIONAL { ?tournament rdfs:label ?tournamentLabel. FILTER(LANG(?tournamentLabel) = "en") }
  # Tournament is instance of or (recursively) part of ATP Tour or Grand Prix tennis circuit
  {
    ?tournament wdt:P31|wdt:P361* wd:Q19317.
  }
  UNION

    ?tournament wdt:P31|wdt:P361* wd:Q615083.
  }
  FILTER NOT EXISTS { ?event wdt:P1346 ?winner. }
}

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 institutions have the highest number of theses or dissertations submitted to them, ordered by the count of distinct theses or dissertations in descending order?

[Assistant]
Let's break down the question:

1. We are looking for institutions (universities, colleges, etc.).
2. We want to count the number of distinct theses or dissertations submitted to each institution.
3. We want to order the institutions by this count in descending order.

First, I need to identify:
- The entity/entities for "thesis" or "dissertation" in Wikidata.
- The property that links a thesis/dissertation to the institution it was submitted to.

I'll start by searching for the entity for "thesis" or "dissertation".

The SPARQL query correctly identifies institutions with the highest number of theses or dissertations submitted to them, using the appropriate properties and entities. It counts distinct theses/dissertations, groups by institution, orders by count in descending order, and retrieves institution IRIs as required. The use of OPTIONAL for labels is appropriate. The answer and query fully satisfy the user's request.
