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] When did Ella Fitzgerald die?

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

[Tool]
Example 1:
Question:
When did princess Diana die?

SPARQL:
SELECT DISTINCT ?date WHERE {
  wd:Q9685 wdt:P570 ?date .
}

[User] When did World War II officially end?

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

[Tool]
Example 1:
Question:
When did Operation Overlord commence?

SPARQL:
SELECT DISTINCT ?date WHERE {
  wd:Q8641370 wdt:P580 ?date .
}

Using entities:
Operation Overlord, also known as Battle of Normandy, Normandy landings (wd:Q8641370): 1944 successful Allied invasion of Nazi-held western Europe in World War II

Using properties:
start time, also known as start date, since, valid, join time, joined (wd:P580 as wdt): time an entity begins to exist or a statement starts being valid, point in time

[Assistant]
The example shows how to query the start date of an event using the property "start time" (wdt:P580). For the end date of World War II, we should look for a property related to "end time" or "end date" for the entity World War II.

Next, I will search for the entity "World War II" in Wikidata to get its identifier.

[Tool]
Top 10 entity alternatives:
1. World War II, also known as 2nd World War, WWII, WW II, WW2, WW 2 (wd:Q362): 1939–1945 global conflict
2. Theatre of War, also known as World War II, World War II RTS: Theatre of War (wd:Q2631997): 2006 video game developed by 1C Company

10. Theatre of War, also known as World War II (wd:Q108371810): video game series

[Assistant] The entity for World War II is wd:Q362. Now, I will search for properties related to the end date or end time of World War II. I will search for properties related to "end" for this entity.

[Tool]
Top 10 property alternatives:
1. end time, also known as ends, stop time, endtime, fall date, ineffective (wd:P582 as p/wdt): moment when an entity ceases to exist and a statement stops being entirely valid or no longer be true, point in time

10. described by source, also known as mentioned in, source of item, reviewed in, mentioned in news article, talked about in (wd:P1343 as p/wdt): work where this item is described, attested in

No other items found

[Assistant] The property "end time" (wdt:P582) is the most suitable to find the official end date of World War II. I will now write a SPARQL query to get the end time of World War II (wd:Q362).

[Tool] No examples found

[Assistant] There are no direct similar examples found for the question "What is the Fujiyama made of?" Let's first identify the entity "Fujiyama" in Wikidata to understand what it refers to. It might refer to Mount Fuji or something else named Fujiyama. I will search for the entity "Fujiyama" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. Mount Fuji, also known as Mt. Fuji, Mt Fuji, Fujiyama, Fuji-yama, Fuji-san (wd:Q39231): volcano in Yamanashi and Shizuoka Prefectures, Japan
2. Fujiyama, also known as Fujiyama (roller coaster) (wd:Q788077): roller coaster in Fujiyoshida, Japan

10. Tomofumi Fujiyama, also known as Fujiyama Tomofumi (wd:Q38277863): Japanese association football player (1994-), association football player

[Assistant]
The term "Fujiyama" can refer to multiple entities, but the most common and likely intended one is Mount Fuji (wd:Q39231), which is a volcano in Japan and also known as Fujiyama. Another possibility is a roller coaster named Fujiyama (wd:Q788077).

Since the question "What is the Fujiyama made of?" most likely refers to the composition of Mount Fuji, I will proceed with the entity Mount Fuji (wd:Q39231) and search for properties related to its composition or what it is made of.

Feedback (status=done):
The SPARQL query correctly retrieves the material that Mount Fuji (Fujiyama) is made of using property P186 (made from material). The query returns basalt as the material, which matches the answer provided. The query also includes the English label for the material, which is helpful for readability. The query follows the rules by returning the actual identifier (wd:Q43338) and the label optionally. The answer is accurate and complete based on the data from Wikidata. No further refinement is necessary.

[User] What event killed the most people in the years 1910 to 1920?

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

[Tool]
Example 1:
Question:
What is the most frequent cause of death?

SPARQL:
SELECT ?uri WHERE {
  ?s wdt:P509 ?uri .
}
GROUP BY ?uri
ORDER BY DESC ( COUNT( DISTINCT ?s ) )
LIMIT 1

Using properties:
cause of death, also known as death cause, murder method, method of murder, die of, die from (wd:P509 as wdt): underlying or immediate cause of death.  Underlying cause (e.g. ...adest category, e.g. natural causes, accident, homicide, suicide

[Assistant]
The example found is about finding the most frequent cause of death using the property "cause of death" (wdt:P509). However, the question is about the event that killed the most people in a specific time range (1910 to 1920).

I need to find events that caused deaths and the number of deaths caused by those events, then filter by the date range 1910 to 1920, and finally find the event with the maximum number of deaths.

Step 1: Find the property for "number of deaths" or "death toll" related to events.
Step 2: Find the property for "start time" or "date" of events.
Step 3: Query events with death toll and date within 1910 to 1920.
Step 4: Sort by death toll and get the top event.

I will start by searching for the property related to "number of deaths" or "death toll".

2. number of casualties, also known as casualities, number of deaths and injuries (wd:P1590 as ps/wdt/prn/wdtn/p/psv/pr/prv/pq/pqn/psn/pqv): number of people dead or injured because of this event.  Used wh...e data on number of deaths and number of injured is unavailable.
3. number of victims of killer, also known as number of persons killed, number of killed persons, number of homicide victims, kills, kill count (wd:P1345 as ps/wdt/prn/wdtn/p/psv/pr/prv/pq/pqn/psn/pqv): people killed by the subject, both legal and illegal
4. death rate, also known as mortality rate (wd:P10091 as ps/wdt/prn/wdtn/p/psv/pr/prv/pq/pqn/psn/pqv): the total number of persons dead per 1,000 population per year

6. number of graves, also known as total number of graves, capacity cemetery (wd:P2351 as ps/wdt/prn/wdtn/p/psv/pr/prv/pq/pqn/psn/pqv): number of burial places in a cemetery or necropolis, maximum capacity, quantity
7. quantity buried, also known as burials, graves, number of burials, number of people buried (wd:P2324 as ps/wdt/prn/wdtn/p/psv/pr/prv/pq/pqn/psn/pqv): number of remains buried or interred, quantity
8. number of losses, also known as defeats, games lost, L, losses, lost (wd:P1356 as ps/wdt/prn/wdtn/p/psv/pr/prv/pq/pqn/psn/pqv): number of sporting matches, games or events lost

10. number of survivors, also known as survivors (wd:P1561 as ps/wdt/prn/wdtn/p/psv/pr/prv/pq/pqn/psn/pqv): number of people surviving an event

[Assistant] The property "number of deaths" (wdt:P1120) seems to be the most relevant for the number of people who died as a direct result of an event. Next, I will search for the property related to the date or time of an event. I will search for "start time" or "date" related to events.

[Assistant] The property "start time" (wdt:P580) is suitable for the time an event begins. Now I will construct a SPARQL query to find events with a start time between 1910 and 1920 and with a number of deaths, then order by the number of deaths in descending order and limit to the top 1 event. I will also include labels for better readability.

| ----------------------------------------------------------------------- |
| Straßenschlachten infolge des Generalstreik im März 1919 in Berlin (de) |

[Assistant]
The event wd:Q124001869 is labeled in German as "Straßenschlachten infolge des Generalstreik im März 1919 in Berlin," which translates to "Street battles following the general strike in March 1919 in Berlin."

I will now check if there are other events with a higher death toll in the same period by expanding the limit to a few more results.

[Assistant]
The events with the highest death tolls between 1910 and 1920 in the data are:

1. Event wd:Q124001869 (no English label) with 2000 deaths, starting on 1919-03-03.
2. The same event wd:Q124001869 with 1200 deaths (possibly different data source or qualifier).
3. Spartacist uprising (wd:Q313329) with 200 deaths, starting on 1919-01-05.

The event with the most deaths is wd:Q124001869, which is the "Straßenschlachten infolge des Generalstreik im März 1919 in Berlin" (Street battles following the general strike in March 1919 in Berlin).

Feedback (status=refine):
The SPARQL query correctly identifies an event within the specified time range and orders by the number of deaths to find the event with the most fatalities. However, the returned event label is missing in English, which reduces the clarity of the answer. The query attempts to get the English label but the result is empty, possibly because the event does not have an English label in Wikidata. To improve the answer, the query could also retrieve labels in other languages (e.g., German) or include the label without language filtering to provide a human-readable name. Additionally, it would be good to verify if the event with 2000 deaths is indeed the highest fatality event in that period by checking if the data is complete or if other events might have higher death counts but missing start times or death counts. Overall, the answer is sensible but could be improved by ensuring the label is shown and by confirming completeness of the data.

[Assistant] Thank you for the feedback. To improve the answer, I will modify the query to retrieve the event label without language filtering so that we can get a human-readable name even if it is not in English. Additionally, I will check if there are events with missing start times but with death counts in the range 1910-1920 to ensure completeness. I will first update the query to get the label without language filtering and re-check the top event.

[Tool]
SPARQL execution failed:
Operation timed out. Last operation: IndexScan ?event <http://www.w3.org/2000/01/rdf-schema#label> ?eventLabel

[Assistant] The query timed out likely due to the removal of the language filter on labels, which increased the result set size significantly. To avoid this, I will limit the label retrieval to English and German languages only, as German was the language of the existing label. This should provide a human-readable label without causing a timeout.

[Tool]
SPARQL execution failed:
Operation timed out. Last operation: Filter ( LANG ( ?eventLabel ) = "en" || LANG ( ?eventLabel ) = "de" )

[Assistant] The query still times out with the language filter on English or German labels. To avoid timeout, I will remove the label retrieval from the main query and instead retrieve the label for the top event separately after identifying it by its death toll and start time. This approach limits the initial query complexity and avoids timeouts. I will first run the query without labels to get the top event, then query its label separately.

Feedback (status=refine):
The SPARQL query correctly retrieves events between 1910 and 1920 with their number of deaths and orders them by deaths to find the event with the most deaths. However, the query only considers events that have a start time (wdt:P580) and number of deaths (wdt:P1120), but it does not consider the possibility that some events might have an end time or that deaths might be recorded differently. Also, the query does not retrieve the label of the event in English or any language, which would be helpful for the user. It is recommended to add an OPTIONAL clause to get the rdfs:label in English or fallback to any language, and to consider if filtering by start time alone is sufficient or if end time should be considered as well. Additionally, the event found has only 2000 deaths, which seems low for the most deadly event in that decade; it might be worth checking if other events with higher death tolls exist but are missing start times or deaths properties. Overall, the answer is correct given the query, but the query could be refined to improve completeness and user-friendliness.

[Assistant]
Thank you for the detailed feedback. To improve the query and answer, I will:

1. Consider both start time (wdt:P580) and end time (wdt:P582) of events to capture events that span the 1910-1920 period.
2. Retrieve the event label optionally in English, and if not available, fallback to any language.
3. Check for events that might have death counts recorded differently or missing start times but with end times in the range.
4. Ensure the query returns the event with the highest death toll considering these refinements.

I will now construct a refined SPARQL query accordingly.

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 countries is the Himalayas located?

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

[Tool]
Example 1:
Question:
To which countries does the Himalayan mountain system extend?

SPARQL:
SELECT DISTINCT ?uri WHERE {
  wd:Q5451 wdt:P17 ?uri .
}

Using entities:
Himalayas, also known as Himalaya, Himálaya, Himalaya Mountains, Himálaya Mountains, Himalayan Mountains (wd:Q5451): mountain range in Asia

Using properties:
country, also known as sovereign state, state, land, host country (wd:P17 as wdt): sovereign state that this item is in (not to be used for human beings), located in the administrative territorial entity

Example 2:
Question:
What country is Mount Everest in?

SPARQL:
SELECT DISTINCT ?uri WHERE {
  wd:Q513 wdt:P17 ?uri .
}

Using entities:
Mount Everest, also known as Chomolungma, Chomolangma, Zhumulangma, World highest peak, Sagarmāthā (wd:Q513): Earth's highest mountain above sea level, located in the Mahalangur Himal sub-range of the Himalayas

Using properties:
country, also known as sovereign state, state, land, host country (wd:P17 as wdt): sovereign state that this item is in (not to be used for human beings), located in the administrative territorial entity

Example 3:
Question:
Give me the capitals of all countries that the Himalayas run through.

SPARQL:
SELECT DISTINCT ?uri WHERE {
  wd:Q5451 wdt:P17 ?country .
  ?country wdt:P36 ?uri .
}

Using entities:
Himalayas, also known as Himalaya, Himálaya, Himalaya Mountains, Himálaya Mountains, Himalayan Mountains (wd:Q5451): mountain range in Asia

Using properties:
country, also known as sovereign state, state, land, host country (wd:P17 as wdt): sovereign state that this item is in (not to be used for human beings), located in the administrative territorial entity
capital, also known as administrative seat, seat of government, seat, principal place, location of capital (wd:P36 as wdt): seat of government of a country, province, state or other type of administrative territorial entity

[Assistant] The Himalayas is represented by the entity wd:Q5451 in Wikidata. The property for the country in which an entity is located is wdt:P17. So, to find the countries in which the Himalayas are located, we can query for the countries (wdt:P17) of the Himalayas (wd:Q5451). I will now write and execute this query.

Feedback (status=refine):
The SPARQL query uses the property wdt:P17 (country) on the Himalayas (wd:Q5451), which is not appropriate because wdt:P17 indicates the country an item is located in, typically for administrative entities, not for mountain ranges. This property does not correctly capture the countries where the Himalayas extend. Instead, the query should find the countries that have parts of the Himalayas within their territory. A better approach is to find all countries that have a territorial part (wdt:P361 or wdt:P527) that is part of the Himalayas or to find the countries that contain mountains or mountain ranges that are part of the Himalayas. Alternatively, one can query for countries that have the Himalayas as a mountain range within their borders using the property wdt:P276 (location) or wdt:P131 (located in the administrative territorial entity) on the Himalayas or its parts. The current query returns the countries that the Himalayas item is stated to be in, but this is not the correct modeling in Wikidata. Therefore, the answer might be incomplete or incorrect. The system should refine the query to correctly retrieve all countries where the Himalayas are located.

[Assistant]
Thank you for the feedback. The property wdt:P17 (country) is not appropriate for the Himalayas as a mountain range. Instead, I should find countries that contain parts of the Himalayas or have mountains that are part of the Himalayas within their territory.

I will refine the query by:
- Finding mountain entities that are part of the Himalayas (using wdt:P361 "part of" or wdt:P527 "has part").
- Then finding the countries (wdt:P17) where these mountains are located.

I will first check for mountains that are part of the Himalayas using wdt:P361 (part of) property. Then I will find the countries of these mountains. I will write and execute this refined query.

[Assistant]
The refined query found only three countries: China, India, and Nepal. This seems incomplete because the Himalayas extend to more countries.

I will try another approach:
- Find mountain ranges that are part of the Himalayas (wdt:P361).
- Find mountains that are part of these mountain ranges.
- Find the countries of these mountains.

This might give a more complete list of countries. I will write and execute this query.

[Assistant]
The query with subranges of the Himalayas returned only China and Nepal, which is still incomplete.

I will try a different approach:
- Find mountains that have the Himalayas as a mountain range (wdt:P131 "located in the administrative territorial entity" or wdt:P276 "location").
- Then find the countries of these mountains.

I will write and execute this query now.

[Assistant]
No results were found using the property wdt:P131 (located in the administrative territorial entity) for mountains located in the Himalayas.

I will try using the property wdt:P276 (location) for mountains located in the Himalayas and then find their countries.

[Assistant]
The query using wdt:P276 (location) found China, Tibet, and Nepal. Tibet is a region within China, so it is not a separate country.

I will now try to find countries that have parts of the Himalayas using the property wdt:P361 (part of) or wdt:P527 (has part) on the Himalayas to find parts, and then find the countries of those parts.

I will first check the parts of the Himalayas using wdt:P527 (has part).

[Tool] Got no rows and 2 columns

[Assistant]
There are no parts listed for the Himalayas using the property wdt:P527 (has part).

I will now try to find parts of the Himalayas using the property wdt:P361 (part of) where the Himalayas is the object. This means finding entities that are part of the Himalayas. Then I will find the countries of those parts.

[Assistant]
The query returned many administrative divisions and regions, but only one country: Nepal. The rest are subnational entities.

I will now try to find the countries of these administrative divisions by querying the countries that these divisions are part of using wdt:P17 (country). I will write and execute this query.

The query again returned only China, India, and Nepal as countries.

I will try one last approach:
- Find mountains that are part of the Himalayas or its subranges.
- Find the countries of these mountains.
- Also include countries that have the Himalayas as a mountain range within their territory using wdt:P276 (location).

I will combine these approaches in one query to get a more complete list of countries.

[Assistant]
The combined query found China, Tibet, India, and Nepal. Tibet is a region within China, so it is not a separate country.

I will now try to find countries that have the Himalayas as a mountain range within their borders using the property wdt:P206 (located next to body of water) or other location-related properties on the Himalayas or its parts.

I will try to find the countries that have the Himalayas or its parts within their borders using the property wdt:P17 on the countries that have the Himalayas or its parts as a territorial entity (wdt:P131 or wdt:P276).

[Tool] Got no rows and 2 columns

[Assistant]
No results were found using the properties wdt:P131 or wdt:P276 on the Himalayas itself to find countries.

Given the complexity and the incomplete modeling of the Himalayas in Wikidata, the best available information from the parts and mountains related to the Himalayas shows that the countries China, India, and Nepal are definitely part of the Himalayas.

I will provide this as the answer with an explanation about the limitations.

[User]
Feedback (status=refine):
The SPARQL query correctly identifies countries related to the Himalayas, including China, India, and Nepal. However, it also returns Tibet, which is a region and not a sovereign country. The query should be refined to exclude non-sovereign entities like Tibet to better answer the question about countries. Additionally, the query could be improved by considering other possible properties or relations that might link the Himalayas to countries to ensure completeness. Overall, the answer is mostly correct but the query needs refinement to exclude regions and focus on sovereign states only.

[Assistant]
Thank you for the feedback. To refine the query, I will exclude non-sovereign entities like Tibet by ensuring that the returned countries are instances of sovereign states (wd:Q3624078) or countries (wd:Q6256).

I will modify the query to include a condition that the ?country is an instance of (wdt:P31) either sovereign state or country.

I will now write and execute this refined 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.

Colin Duffy was born in Broomfield, which is located in Colorado.

Both Brooke Raboutou and Colin Duffy are from the state of Colorado in the USA.

Feedback (status=done):
The SPARQL query correctly identifies the birthplaces of Brooke Raboutou and Colin Duffy and checks if they belong to the same state in the USA. The query uses the property P19 (place of birth) and the administrative territorial entity property P131 to find the states. The filter ensures that only matching states are returned. The result shows both are from Colorado, which answers the question accurately. The query follows all rules, returns the identifiers of the states, and the answer is clear and complete.
