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] where is the seat of the african union?

[Assistant]
Let's break down the question:

1. The "African Union" is an entity we need to identify in Wikidata.
2. The "seat" refers to the administrative center or headquarters of the organization.

First, I will search for the entity "African Union" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. African Union, also known as African union, AU, The African Union, UA, Union Africaine (wd:Q7159): supranational union in Africa
2. African Union (wd:Q59167361): 2014 scholarly article by Paul Jackson
3. flag of the African Union, also known as African Union flag, the African Union flag (wd:Q630077): flag
4. African Monetary Union (wd:Q388083): proposed economic and monetary union
5. African Union Passport, also known as AU Passport, Passport (African Union) (wd:Q25927278): common passport document for citizens of African Union member states

7. African Judo Union, also known as AJU (wd:Q3606247): Judo union
8. Kenya African Union (wd:Q6392541): political organization
9. African Parliamentary Union (wd:Q25098864): interparliamentary organization
10. African Boxing Union (wd:Q11284666)

[Assistant]
The correct entity for the African Union is wd:Q7159.

Next, I need to find the property that indicates the "seat" or "headquarters location" of an organization. I will search for properties related to "seat" or "headquarters".

[Tool]
Top 10 property alternatives:
1. headquarters location, also known as headquarters locality, seat, headquarters town, HQ, HQ location (wd:P159 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): city or town where an organization's headquarters is or has been situated. Use P276 qualifier for specific building, significant place

3. organization directed by the office or position, also known as leader of, head of, leads, organization directed by, organization directed from the office (wd:P2389 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): organization which is directed by this office
4. employer, also known as working at, working for, working place, works at, works for (wd:P108 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): person or organization for which the subject works or worked, affiliation
5. has subsidiary, also known as subordinate body, subsidiary body, subordinate unit, subsidiary, subsidiary company (wd:P355 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): subsidiary of a company or organization; generally a fully owned...siness division" (P199). Opposite of parent organization (P749)., has part(s), owner of
6. operating area, also known as province served, serves jurisdiction, serves geographic region, serves geographic area, serves area (wd:P2541 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): geographic area or jurisdiction an organisation or industry operates in, serves, or has responsibility for, location
7. work location, also known as work place, working from, working at, worked from, worked at (wd:P937 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): location where persons or organisations were actively participating in employment, business or other work, significant place, location

[Assistant]
The property "headquarters location" (wd:P159) is the most appropriate for finding the seat of the African Union.

Now, I will write a SPARQL query to find the headquarters location (seat) of the African Union (wd:Q7159), and also try to retrieve a human-readable label for the result.

[Tool]
Got 2 rows and 2 columns:
| ?seat                    | ?seatLabel   |

[User] through which countries of the sahel does the niger river flow?

[Assistant]
Let's break down the question:

1. We need to identify the countries of the Sahel.
2. We need to identify the Niger River.
3. We need to find which Sahel countries the Niger River flows through.

First, let's search for the entity "Sahel" to identify how it is represented in Wikidata.

[Tool]
Top 10 entity alternatives:
1. Sahel, also known as West African Sahel, West African Sahel region (wd:Q66065): ecoclimatic and biogeographic transition zone in Africa
2. Sahel, also known as Sahel, Tunisia (wd:Q957052): region of Tunisia
3. Sahel (wd:Q3461536): commune of Mali
4. Sahel (wd:Q7399580): town in Larache Province, Morocco
5. Sahel (wd:Q28899612): douar in Morocco
6. Sahel (wd:Q28899611): douar in Morocco (Al Hoceima)
7. Sahel (wd:Q7399583): former province of Eritrea

9. Sahel, also known as Sahel (app), Sahel app, Sahel (application), Sahel application, The Unified Government Application of Electronic Services (wd:Q108520833): Kuwaiti government application
10. Sahel, also known as Sahel (family name), Sahel (surname) (wd:Q68518612): family name

[Assistant]
The relevant entity for the Sahel region is wd:Q66065 ("Sahel, also known as West African Sahel, West African Sahel region"). Next, we need to determine which countries are considered part of the Sahel.

I'll check if there is a property or statement on wd:Q66065 that lists its member countries.

[Assistant]
There is no direct "has part" or "contains country" property, but sometimes "country (wdt:P17)" is used. However, for wd:Q66065, "country" points to Egypt, which is not typically considered part of the Sahel.

To be thorough, let's search for properties related to "member" or "contains" on the Sahel entity to see if there's a better way to get the list of Sahel countries.

No other items found

[Assistant]
There is no direct property on the Sahel entity listing its member countries. However, the Sahel is a well-known geographic region, and its countries are often listed in external sources. In Wikidata, sometimes the "located in the administrative territorial entity" or "part of" properties are used for such relationships.

Alternatively, let's search for entities that are subclasses or instances of "country of the Sahel" or similar, to see if there is a category or list in Wikidata.

[Assistant]
There is no direct entity for "country of the Sahel." Since the Sahel is a geographic region, let's try searching for countries that are "located in" or "part of" the Sahel (wd:Q66065).

I'll search for entities that are "located in the administrative territorial entity" (P131) or "part of" (P361) the Sahel. Let's start by searching for countries (instance of: wd:Q6256) that are "located in" the Sahel.

The property "located in the administrative territorial entity" (wd:P131) is a good candidate. Let's try to find countries (instance of: wd:Q6256) that are located in the Sahel (wd:Q66065) using this property.

I'll write a query to find all entities that are instances of "country" and are "located in the administrative territorial entity" Sahel.

[Assistant]
No countries are directly marked as "located in the administrative territorial entity" Sahel in Wikidata. This is not surprising, as such broad regions are not always used this way in Wikidata.

Let's try another approach: Let's look for a list or category of "Sahel countries" in Wikidata, perhaps as a subclass or as part of a list. I'll search for entities related to "List of Sahel countries".

[Assistant]
There is no direct "List of Sahel countries" entity in Wikidata. Since Wikidata does not seem to have a direct way to get the list of Sahel countries, let's focus on the other part of the question: the Niger River.

Let's search for the Niger River entity in Wikidata.

[Assistant]
The correct entity for the Niger River is wd:Q3542. Now, let's check which countries the Niger River flows through. There is likely a property such as "flows through" or "country" associated with rivers.

Let's search for properties related to "country" or "flows through" for the Niger River entity.

The Niger River flows through the following countries according to Wikidata: Nigeria (wd:Q1033), Mali (wd:Q912), Benin (wd:Q962), Niger (wd:Q1032), and Guinea (wd:Q1006).

Now, to answer the original question, we need to intersect this list with the countries of the Sahel. Since we could not find a direct list of Sahel countries in Wikidata, let's search for which of these five countries are considered part of the Sahel in Wikidata.

Let's check if these countries are "part of" or "located in" the Sahel (wd:Q66065). I'll check for each country.

[Assistant]
None of the five countries (Mali, Niger, Nigeria, Benin, Guinea) are directly marked as "part of" or "located in" the Sahel in Wikidata; they are all marked as "part of" West Africa.

However, based on widely accepted definitions, the core Sahel countries are generally considered to be: Senegal, Mauritania, Mali, Burkina Faso, Niger, Nigeria, Chad, and Sudan. Of the countries through which the Niger River flows, Mali, Niger, and Nigeria are universally considered Sahel countries.

Therefore, the Niger River flows through the following Sahel countries: Mali (wd:Q912), Niger (wd:Q1032), and Nigeria (wd:Q1033).

I will now write a SPARQL query that returns the intersection of countries through which the Niger River flows and those that are considered part of the Sahel, based on the best available Wikidata information. Since Wikidata does not have a direct "Sahel country" property, I will use a VALUES clause for the three countries (Mali, Niger, Nigeria) that are universally considered Sahel countries and are traversed by the Niger River.

Here is the final SPARQL 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.

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 has shannen doherty played in?

[Assistant]
Let's break down the question:

1. The user is asking for works (movies, TV shows, etc.) that Shannen Doherty has acted in.
2. First, I need to identify the entity for Shannen Doherty in Wikidata.
3. Then, I need to find the relevant property that links a person to works they have acted in (usually "cast member", "actor", or similar).
4. Finally, I will construct a query to list the works Shannen Doherty has played in.

Let's start by searching for the entity "Shannen Doherty" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. Shannen Doherty, also known as Shannen Maria Doherty (wd:Q207598): American actress (1971–2024), television producer, television actor, autobiographer, stage actor, film actor, director
2. Shannen Doherty/Cypress Hill, also known as Saturday Night Live, season 19 episode 2 (wd:Q110713281): episode of Saturday Night Live (S19 E2)
3. Breaking Up with Shannen Doherty (wd:Q1254572): American reality television series
4. William Doherty, also known as Doherty (wd:Q3568555): American entomologist (1857–1901), lepidopterist, zoologist
5. Doherty (wd:Q21502096): family name
6. Dougherty, also known as Doherty (wd:Q19597014): Apple cultivar
7. Doherty (wd:Q48804147): place in Ontario, Canada
8. Doherty (wd:Q105797558): male given name
9. Doherty (wd:Q115263223): geographic township in Ontario, Canada
10. Doherty (wd:Q29167373): lieu-dit in Bristol, Quebec, Canada

[Assistant]
The correct entity for Shannen Doherty is wd:Q207598.

Next, I need to find the property that links an actor to the works they have acted in. This is typically "cast member" (P161) for works, or "filmography" or "actor in" for people. To be sure, I'll search for properties related to "filmography" or "acted in" for Shannen Doherty.

[Tool]
Top 10 property alternatives:
1. filmography, also known as list of films with the person, list of films the person contributed to, list of films about the person (wd:P1283 as p/wdt): item for the list of films a person has contributed to. Don't us...mber" (P161) on items for films, directors with "director" (P57), list of works
2. TMDB person ID, also known as TMDb person identifier, the movie db person id, themoviedb.org person identifier, themoviedb.org person ID, The Movie Database person identifier (wd:P4985 as p/wdt): identifier for a person at The Movie Database

5. Danish National Filmography person ID, also known as Danish National Filmography name, DNF person ID, DNF name, DNF ID (person), DFI person ID (wd:P2626 as p/wdt): identifier for a person in the Danish National Filmography
6. AllMovie person ID, also known as AllMovie ID (wd:P2019 as p/wdt): identifier for a person on the AllMovie film database
7. notable work, also known as artwork, wrote, writer of, works, work (wd:P800 as p/wdt): notable scientific, artistic or literary work, or other work of significance among subject's works
8. Ciné-Ressources person ID, also known as Cine person ID, Ciné-Ressources person identifier, cineressources.net person identifier, cineressources.net person ID, Cine person identifier (wd:P3204 as p/wdt): page of a person on the website "Ciné-Ressources"
9. KMDb person ID, also known as Korean Movie Database person ID (wd:P1649 as p/wdt): identifier for a person on the Korean Movie Database (KMDb)
10. MYmovies person ID (wd:P9995 as p/wdt): identifier for a person on the MYmovies film database

No other items found

[Assistant]
The property "filmography" (wd:P1283) is present, but it is used for a list item, not for direct links to works. The more standard way is to find all works (films, TV shows, etc.) where Shannen Doherty (wd:Q207598) is a "cast member" (P161).

To confirm, I'll search for properties related to "cast member" or "actor" to ensure I use the correct property for linking a person to works they've acted in.

[Tool]
Top 10 property alternatives:
1. cast member, also known as feat., starring (film/play), film starring, starring, actor (wd:P161 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): actor in the subject production [use "character role" (P453) and...use "recorded participant" (P11108) for non-fiction productions], significant person, performer
2. agent of action, also known as being done by, initiator, initiated by, done by, doer (wd:P12995 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): particular item that initiates this action or class of actions
3. performer, also known as actor, sung by, singer, recording by, recorded by (wd:P175 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): actor, musician, band or other performer associated with this role or musical work, contributor to the creative work or subject
4. agents of action have role, also known as actors have role, agent has role, agent of action has role, agents have role, done by agent(s) with role (wd:P12993 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): role that agents of this action take on in the context of this action
5. used by, also known as armiger, user, played by, of (wd:P1535 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): item or concept that makes use of the subject (use sub-properties when appropriate)
6. depicted by, also known as acted by, shown in, seen in, portrayed by, played by (wd:P1299 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): object depicting this subject (object being creative works such as books, films, paintings)
7. character role, also known as role, plays, performer of, as, acting role (wd:P453 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): specific role played or filled by subject -- use only as qualifier of "cast member" (P161), "voice actor" (P725)
8. describes actor of (wd:P12027 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): predicate sense whose actor (an agent or a cause—basically the instigator of an action) is denoted by this sense
9. notable role, also known as notable character role, notable for character role, notable for role (wd:P10606 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): role in a theatrical, motion picture, television, or other work that a performer is particularly known for, notable work
10. film crew member (wd:P3092 as p/wdt/pqv/prv/wdtn/prn/ps/pqn/psv/pr/psn/pq): member of the crew creating an audiovisual work, used for miscel... available: notably for cast member (P161), director (P57), etc., significant person

[Assistant]
The property "cast member" (wd:P161) is the correct one to use for linking works (films, TV shows, etc.) to the actors who appeared in them. However, this property is used on the work (film, TV show) pointing to the actor, not the other way around.

Therefore, to find all works Shannen Doherty has acted in, I need to query for all items where Shannen Doherty (wd:Q207598) is the object of the "cast member" (wdt:P161) property.

I will now construct a SPARQL query to find all works (films, TV shows, etc.) where Shannen Doherty is a cast member, returning the IRIs and optionally the labels of these works.

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.

[Assistant]
The property "educated at" (wd:P69) is the correct one for "university graduated from" or "alma mater".

Now, I will construct a SPARQL query to find the universities Barack Obama (wd:Q76) graduated from, using the property "educated at" (wd:P69). I will also try to retrieve the university labels for clarity, but the main result will be the university IRIs.
