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.

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 how many countries has IKEA been established?

[Assistant]
Let's break down the question:

1. We need to identify the entity for IKEA.
2. We need to find the property that links IKEA to the countries where it has been established (likely "country of operation" or similar).
3. We need to count the number of unique countries.

First, I'll search for the entity "IKEA" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. IKEA, also known as Ikea, Ingvar Kamprad Elmtaryd Agunnaryd (wd:Q54078): international furniture store chain
2. Ikea (wd:Q18587732): genus of insects
3. Ikea effect (wd:Q1653973): cognitive bias in which consumers place a disproportionately high value on products they partially created
4. Swedish meatballs, also known as IKEA meatballs, Köttbullar (wd:Q1501015): Swedish dish made from ground meat
5. Blåhaj, also known as BLÅHAJ, funny meme shark, IKEA shark, Klappar Haj, Smolhaj (wd:Q107133815): stuffed toy shark sold at IKEA

9. IKEA Heights (wd:Q15995166): Comedy web series
10. IKEA Sendai (wd:Q17988690)

[Assistant]
The correct entity for IKEA, the international furniture store chain, is wd:Q54078.

Next, I need to find the property that links IKEA to the countries where it operates or has been established. I'll search for properties related to "country" for this entity.

No other items found

[Assistant]
The search for properties related to "country" for IKEA did not directly return a property like "country of operation." The closest is "location of formation" (wd:P740), but that refers to where IKEA was founded, not where it operates.

To find the correct property, I'll broaden the search to properties related to "operation" or "presence" in a country.

[Assistant]
The property "operating area" (wd:P2541) seems to be the most relevant for finding the countries where IKEA operates.

Next, I will check how this property is used for IKEA to ensure it links to countries and not just regions or cities.

[Tool] Got no rows and 3 columns

[Assistant]
It appears that the "operating area" property (wd:P2541) is not directly used for IKEA in Wikidata, or at least not with any values.

Given this, I'll try searching for other properties that might link IKEA to countries, such as "present in" or "has store in country."

Top 10 property alternatives:
1. contains, also known as container of, contents, encloses, has contents, holds (wd:P4330 as ps/p/psn/pqv/psv/pr/pq/prv/pqn/prn/wdtn/wdt): item or substance located within this item but not part of it

[Assistant]
The property "number of branches" (wd:P8368) might give the number of stores, but not the countries. "Official shop URL" and "location information URL" are not relevant. "Valid in place" (wd:P3005) could be used for countries where something is valid, but may not be used for store presence.

Since direct properties are not yielding results, another approach is to look for IKEA stores (subsidiaries or instances) and see in which countries they are located. I'll search for entities related to "IKEA store" to see if individual stores are modeled and linked to countries.

10. IKEA, also known as Ikea, Ingvar Kamprad Elmtaryd Agunnaryd (wd:Q54078): international furniture store chain

[Assistant]
There is an entity "IKEA store" (wd:Q50399787), which represents stores operated by IKEA. There are also specific stores for various cities.

A possible approach is to find all instances of "IKEA store" and retrieve the countries they are located in. This should give us the set of countries where IKEA has been established.

I'll check which property links an IKEA store to its country.

The property "country" (wd:P17) is the standard way to link a place or building to its country.

I will now write a SPARQL query to:
- Find all entities that are instances of "IKEA store" (wd:Q50399787)
- Get the country (wd:P17) for each store
- Count the number of unique countries

Let's proceed with this query.

[Assistant]
The most relevant property is "place of death" (wdt:P20). Since Julius Caesar was murdered, his place of death should correspond to the place where he was murdered.

Now, I will write a SPARQL query to retrieve the place of death for Julius Caesar (wd:Q1048), and also try to get its label for clarity.

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. 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 year was Riverdale first aired?

[Assistant]
Let's break down the question:

1. The user is asking for the year when the TV show "Riverdale" first aired.
2. I need to identify the entity for "Riverdale" (the TV series) and the property for "first aired" or "original air date".

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

[Tool]
Top 10 entity alternatives:

10. Riverdale, also known as Riverdale, ND, Riverdale, North Dakota (wd:Q2373536): human settlement in McLean County, North Dakota, United States of America

[Assistant]
The top result for "Riverdale" is the American teen drama television series (wd:Q23001951), which matches the context of the question.

Next, I need to find the property in Wikidata that represents "first aired" or "original air date". I will search for properties related to "first aired".

[Tool]
Top 10 property alternatives:
1. location of first performance, also known as premiere, premiered at, premiere held at, premiere location, world premiere (wd:P4647 as ps/p/psn/pqv/psv/pr/pq/prv/pqn/prn/wdtn/wdt): location where a work was first debuted, performed or broadcasted, significant place

[Assistant]
From the property search, "publication date" (wd:P577) and "date of first performance" (wd:P1191) are both relevant. For TV series, "publication date" (P577) is commonly used for the original air date.

Now, I will check if "Riverdale" (wd:Q23001951) has a value for "publication date" (wdt:P577).

[Tool] Got no rows and 3 columns

[Assistant]
It appears that there is no direct "publication date" (P577) triple for "Riverdale" (wd:Q23001951) in the knowledge graph. However, sometimes TV series have their air dates attached to individual seasons or episodes, or possibly under a different property.

Next, I will check if "date of first performance" (P1191) is used for "Riverdale".

[Tool] Got no rows and 3 columns

[Assistant]
There is also no "date of first performance" (P1191) for "Riverdale" directly. Since neither "publication date" nor "date of first performance" is directly attached, I will check if the first season or first episode of "Riverdale" has an air date.

First, I will search for properties of "Riverdale" related to "season" or "episode".

No other items found

[Assistant]
The property "number of seasons" (P2437) is present, but it doesn't link to the season entities themselves. There is also "start time" (P580), which could potentially indicate the start date of the series.

I will now check if "start time" (P580) is used for "Riverdale".

1. The user is asking for the English term for the female equivalent of an "emperor."
2. I need to identify the entity for "emperor" in Wikidata, and then look for a property or entity that represents the female form or equivalent.
3. The answer should be the English term (label) for the female form.

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

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Who is the current president of the German Bundestag currently?

[Assistant]
Let's break down the question:

1. We are looking for the current president of the German Bundestag.
2. We need to identify the entity for the German Bundestag and the property for its president (specifically the current one).

First, I'll search for the entity "German Bundestag" in Wikidata.

[Tool]
Top 10 entity alternatives:
1. German Bundestag, also known as Bundestag of Germany, German parliament (wd:Q154797): legislature of Germany; parliament
2. 21st German Bundestag, also known as Twenty-first German Bundestag (wd:Q124661964): legislative term from 2025 to 2029 (expected)
3. 20th German Bundestag, also known as Twentieth German Bundestag (wd:Q33091469): legislative term from 2021 to 2025
4. 1st German Bundestag, also known as First German Bundestag (wd:Q30542687): legislative term from 1949 to 1953
5. 2nd German Bundestag, also known as Second German Bundestag (wd:Q30542689): legislative term from 1953 to 1957
6. 19th German Bundestag, also known as Nineteenth German Bundestag (wd:Q30579723): legislative term from 2017 to 2021

[Assistant]
The main entity for the German Bundestag is wd:Q154797.

Next, I need to find the property that links the Bundestag to its president, ideally the current one. I'll search for properties related to "president" for the German Bundestag entity.

No other items found

[Assistant]
The most relevant property for the president of the German Bundestag is likely "chairperson" (wd:P488), as it includes "president" as an alias.

Now, I need to check if this property is used to indicate the current president, or if there are qualifiers (such as "end time") to filter for the current officeholder. I'll list some triples for the German Bundestag with the "chairperson" property to see how the data is structured.

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 "creator" (wdt:P170) is the most relevant for identifying the creators of "The OA".

Next, I will check which entities are listed as creators (wdt:P170) of "The OA" (wd:Q19798744).

[Assistant]
The creators of "The OA" are Brit Marling (wd:Q289380) and Zal Batmanglij (wd:Q13499404).

Now, I need to determine which of these creators also acted in "The OA". To do this, I will look for properties related to "cast member" or "actor" for "The OA".

[User] Was Google founded by Bill Gates?

[Assistant]
Let's break down the question:

- We need to check if Bill Gates (person) is a founder of Google (company).
- This is a True/False question, so the SPARQL query should be an ASK query.
- First, let's verify the Wikidata entities for "Bill Gates" and "Google".
- Then, we need to find the property for "founder".

Let's start by searching for the entities "Bill Gates" and "Google".
