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:
wikidata at https://qlever.cs.uni-freiburg.de/api/wikidata-sebastian with notes:
1. When direct properties are missing, chain related properties (e.g., child→child for grandchildren) or search for indirect connections to answer complex relationship queries.
2. For set/class queries (e.g., all cities, all holidays), use instance/subclass chains (P31/P279) for completeness and relevant filters. Be aware of data incompleteness and schema inconsistencies in Wikidata.
3. If queries return too many irrelevant or too few results, try varying properties (country, location, observed in, etc.) and subclass chains, but be ready to report data/model limitations if results remain incomplete or noisy.
4. When a direct property or class is missing or inconsistently used, try related or broader properties/classes (e.g., use inception for independence date, or musical work/composition for musicals) to increase recall.
5. For calculated properties (e.g., population density), combine relevant direct properties (e.g., population, area) in SPARQL queries, as Wikidata may not store the derived value directly.
6. When entity search returns multiple candidates, use context (description, instance type, location, etc.) to disambiguate and select the most relevant entity for the 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. Search for the 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. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
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 just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. 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.
5. 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.
6. 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.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. 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] Is math related to science ?

[Assistant] To answer if math is related to science, I will first identify the entities "math" and "science" in Wikidata and then check if there is any property that links math to science, such as "field of work," "subclass," or "related discipline." I will start by searching for the entities "mathematics" and "science" in Wikidata.

[Assistant] The entities for "mathematics" (wd:Q395) and "science" (wd:Q336) are identified.

[Assistant]
The query failed because the SERVICE wikibase:label is not supported by the QLever endpoint. I will rewrite the query without using SERVICE wikibase:label and instead use rdfs:label optionally to get property labels.

I will check if mathematics (wd:Q395) has any direct property linking it to science (wd:Q336).

| property           | propertyLabel |
| ------------------ | ------------- |
| has use (wdt:P366) |               |

[Assistant] Mathematics (wd:Q395) has a direct property "has use" (wdt:P366) linked to science (wd:Q336). This indicates a relationship that mathematics is used in science. I will now check if science is a broader field or superclass of mathematics by checking subclass or instance relations.

| natural science (wd:Q7991)         | natural science (en)     |

[Assistant] Mathematics (wd:Q395) is classified as an "academic discipline" and "academic major," and also as a "natural science" (wd:Q7991). Since natural science is a subclass of science, this shows a direct classification link between mathematics and science. I will now check if natural science (wd:Q7991) is a subclass of science (wd:Q336) to confirm the hierarchy.

[Tool]
Got 1 row and 1 column:
| superclass        |
| ----------------- |

[Assistant] Natural science (wd:Q7991) is a subclass of science (wd:Q336), confirming that mathematics is related to science through its classification as a natural science, which is a subclass of science. I will now finalize the answer.

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. Search for the 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. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
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 just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. 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.
5. 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.
6. 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.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. 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 colors can water take?

[Assistant]
The question "How many different colors can water take?" is somewhat ambiguous because water itself is typically colorless in small quantities, but it can appear to take on different colors depending on various factors such as impurities, depth, lighting, and the environment.

To answer this question using Wikidata, I will first try to find if there is any property or entity that describes the colors of water or the different colors water can have. I will search for entities related to "water color" or "colors of water" and also look for properties that might describe the color of water.

Step 1: Search for entities related to "water color" or "colors of water" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. color of water, also known as colour of water, water color, water colour (wd:Q5148636)
2. Water color (wd:Q100372250): instance of painting
3. Water color (wd:Q100372253): instance of painting
4. Water Colors (wd:Q7973278): album by Ayako Ikeda, instance of album
5. Water Colors (wd:Q20038886): album by Tomohisa Kawazoe, instance of album
6. Water color drafts-2 (wd:Q59325118): instance of painting, work of Li Mei-shu
7. The Color of Water (wd:Q7726851): 1996 memoir by James McBride, instance of literary work
8. Colorado Water Courts (wd:Q5148978): specialized state courts of Colorado, U.S
9. water in Colorado (wd:Q7973515): instance of aspect in a geographic region, State of Colorado water use and rights
10. Washington Water Color Club, also known as Washington Water Color Association (wd:Q96480225)

[Assistant] I found an entity "color of water" (wd:Q5148636) which seems to be directly related to the concept of water color. I will now check if this entity has any statements or properties that describe the different colors water can take or any related information that might help answer the question.

[Assistant]
The entity "color of water" (wd:Q5148636) is a subclass of "color" (wd:Q1075) and is a facet of "water" (wd:Q283). However, there is no direct property or statement that lists the different colors water can take.

Since the direct entity does not provide a list of colors, I will try to find if there are any colors or color-related properties associated with water (wd:Q283) or if there are any common colors linked to water in Wikidata.

Step 2: Search for properties related to color for the entity "water" (wd:Q283).

[Tool]
Top 10 property alternatives:
1. color, also known as with the colour, with the color, pigment, dye, of the colour (wd:P462 as wdt/p): color of subject
2. instance of, also known as example of, has type, is a, is an, is of type (wd:P31 as wdt/p): type to which this subject corresponds/belongs. Different from P...tains, and the volcano is a type (instance) of volcanic landform
3. image, also known as img, infobox image, photo, photograph, picture (wd:P18 as wdt/p): image of relevant illustration of the subject; if available, als...tor map, flag image, signature image, logo image, collage image)
4. has characteristic, also known as trait, has quality, inherent property, object has characteristic, parameter (wd:P1552 as wdt/p): inherent or distinguishing quality or feature of the entity. Use a more specific property when possible
5. has use, also known as used as, utility, used in, used for, use (wd:P366 as wdt/p): main use of the subject (includes current and former usage)
6. subclass of, also known as subcategory of, subgenre of, sort of, subtype of, type 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
7. has part(s), also known as has ingredient, has ingredients, had part, has member, has part (wd:P527 as wdt/p): part of this subject; inverse property of "part of" (P361). See also "has parts of the class" (P2670).
8. topic's main category, also known as category for this topic, Wikipedia category, Wikimedia category, Wiki category, subject category (wd:P910 as wdt/p): main Wikimedia category
9. mass, also known as displacement, weight, molecular mass, molecular weight (wd:P2067 as wdt/p): mass (in colloquial usage also known as weight) of the item
10. video, also known as gif, animation, trailer, media (wd:P10 as wdt/p): relevant video. For images, use the property P18. For film trailers, qualify with "object has role" (P3831)="trailer" (Q622550)

No other items found

[Assistant]
The property "color" (wdt:P462) is available and is described as "color of subject." This property can be used to find colors associated with water or the color of water.

Step 3: I will now query for the different colors (values of property P462) that are associated with water (wd:Q283) or with the concept "color of water" (wd:Q5148636) to see how many different colors water can take according to Wikidata.

[Tool]
Got 5 rows and 2 columns:

| color of water (wd:Q5148636) | color of water (en) |
| turquoise (wd:Q5960345)      | turquoise (en)      |

[Assistant]
I found 5 different colors associated with water or the color of water in Wikidata: colorless, white, green, color of water, and turquoise. The entry "color of water" itself is listed as a color, which is a bit circular, so excluding that, there are four distinct colors.

I will now provide the final answer with these findings.

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:
wikidata at https://qlever.cs.uni-freiburg.de/api/wikidata-sebastian with notes:
1. When direct properties are missing, chain related properties (e.g., child→child for grandchildren) or search for indirect connections to answer complex relationship queries.
2. For set/class queries (e.g., all cities, all holidays), use instance/subclass chains (P31/P279) for completeness and relevant filters. Be aware of data incompleteness and schema inconsistencies in Wikidata.
3. If queries return too many irrelevant or too few results, try varying properties (country, location, observed in, etc.) and subclass chains, but be ready to report data/model limitations if results remain incomplete or noisy.
4. When a direct property or class is missing or inconsistently used, try related or broader properties/classes (e.g., use inception for independence date, or musical work/composition for musicals) to increase recall.
5. For calculated properties (e.g., population density), combine relevant direct properties (e.g., population, area) in SPARQL queries, as Wikidata may not store the derived value directly.
6. When entity search returns multiple candidates, use context (description, instance type, location, etc.) to disambiguate and select the most relevant entity for the 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. Search for the 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. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
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 just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. 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.
5. 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.
6. 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.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. 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 percentage of Andorra is covered with water?

[Assistant]
To answer the question about the percentage of Andorra covered with water, I need to find the total area of Andorra and the area covered by water within Andorra. Then, I can calculate the percentage of the area covered with water.

Step 1: Identify the entity for Andorra.
Step 2: Find the total area of Andorra.
Step 3: Find the area covered by water in Andorra.
Step 4: Calculate the percentage of water coverage.

I will start by searching for the entity Andorra in Wikidata.

[Assistant]
The entity for the country Andorra is wd:Q228. Next, I will find the total area of Andorra and the area covered by water in Andorra. The property for area is usually "area" (wdt:P2046). For water area, I will check if there is a specific property for water area or water coverage in the entity's properties.

I will first query the total area of Andorra.

[Assistant]
There is a property "water as percent of area" (wdt:P2927) which indicates the percentage of the territory that is water. This property directly answers the question about the percentage of Andorra covered with water.

I will now query the value of this property for Andorra (wd:Q228).

[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:
wikidata at https://qlever.cs.uni-freiburg.de/api/wikidata-sebastian with notes:
1. When direct properties are missing, chain related properties (e.g., child→child for grandchildren) or search for indirect connections to answer complex relationship queries.
2. For set/class queries (e.g., all cities, all holidays), use instance/subclass chains (P31/P279) for completeness and relevant filters. Be aware of data incompleteness and schema inconsistencies in Wikidata.
3. If queries return too many irrelevant or too few results, try varying properties (country, location, observed in, etc.) and subclass chains, but be ready to report data/model limitations if results remain incomplete or noisy.
4. When a direct property or class is missing or inconsistently used, try related or broader properties/classes (e.g., use inception for independence date, or musical work/composition for musicals) to increase recall.
5. For calculated properties (e.g., population density), combine relevant direct properties (e.g., population, area) in SPARQL queries, as Wikidata may not store the derived value directly.
6. When entity search returns multiple candidates, use context (description, instance type, location, etc.) to disambiguate and select the most relevant entity for the query.

2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. 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.
5. 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.
6. 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.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. 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 is the capital of the prefecture Tokyo ?

[Assistant]
Step 1: Identify the entity "Tokyo" as a prefecture and find its capital. In Wikidata, Tokyo is represented as a prefecture of Japan. We need to find the property that links a prefecture to its capital.

Step 2: Search for the entity "Tokyo" in Wikidata to get its identifier.

I will start by searching for the entity "Tokyo" in Wikidata.

[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:
wikidata at https://qlever.cs.uni-freiburg.de/api/wikidata-sebastian with notes:
1. When direct properties are missing, chain related properties (e.g., child→child for grandchildren) or search for indirect connections to answer complex relationship queries.
2. For set/class queries (e.g., all cities, all holidays), use instance/subclass chains (P31/P279) for completeness and relevant filters. Be aware of data incompleteness and schema inconsistencies in Wikidata.
3. If queries return too many irrelevant or too few results, try varying properties (country, location, observed in, etc.) and subclass chains, but be ready to report data/model limitations if results remain incomplete or noisy.
4. When a direct property or class is missing or inconsistently used, try related or broader properties/classes (e.g., use inception for independence date, or musical work/composition for musicals) to increase recall.
5. For calculated properties (e.g., population density), combine relevant direct properties (e.g., population, area) in SPARQL queries, as Wikidata may not store the derived value directly.
6. When entity search returns multiple candidates, use context (description, instance type, location, etc.) to disambiguate and select the most relevant entity for the 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. Search for the 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. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.
