[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:
freebase at http://galera:7002

You can use the following SPARQL prefixes implicitly in all functions:
fb: <http://rdf.freebase.com/ns/
fbkey: <http://rdf.freebase.com/key/

wikibase: <http://wikiba.se/ontology#
qb: <http://purl.org/linked-data/cube#
void: <http://rdfs.org/ns/void#

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 city near the Grand Canyon was an American football player born in?

[Assistant]
Let's break down the question:

1. We need to identify a city near the Grand Canyon.
2. Then, we need to find an American football player who was born in that city.

Step 1: Find the Grand Canyon entity in Freebase.
Step 2: Find cities near the Grand Canyon.
Step 3: For those cities, check if any American football player was born there.

Let's start by searching for the Grand Canyon entity in Freebase.

[Assistant]
The most relevant property for finding cities near the Grand Canyon is "Near travel destination" (fb:travel.tourist_attraction.near_travel_destination), which links tourist attractions to nearby travel destinations.

Let's list the objects (destinations) that are "near travel destination" for the Grand Canyon (fb:m.0cns5) and see if any of them are cities or towns.

[Tool]
Got 3 rows and 3 columns:

[Assistant]
The "near travel destination" property for the Grand Canyon lists:
- Phoenix (fb:m.0d35y)
- Grand Canyon National Park (fb:m.0cnrr)
- Lake Powell (fb:m.01z_xr)

Of these, Phoenix is a city. Let's focus on Phoenix as the city near the Grand Canyon.

Next, we need to find if any American football player was born in Phoenix. Let's search for the property that links a person to their place of birth.

[Assistant]
The most general and relevant property for people is "place of birth" (fb:people.person.place_of_birth).

Now, let's find American football players born in Phoenix. We need to:
1. Identify the entity for "American football player".
2. Find people with that profession whose place of birth is Phoenix.

Let's search for the entity "American football player" in Freebase.

[User]
Feedback (status=refine):
The current SPARQL query only retrieves American football players born in Phoenix, but the user's question asks for a city near the Grand Canyon where an American football player was born. The query assumes Phoenix is near the Grand Canyon without verifying this spatial relationship. To refine the answer, the query should:

1. Identify cities near the Grand Canyon (possibly using spatial or location-based properties).
2. For each such city, check if an American football player was born there.

Currently, the query is too narrow and may miss other relevant cities. Please refine the query to address the geographic aspect of the question.

[Assistant]
Thank you for the feedback. You are correct: the previous approach assumed Phoenix was the only relevant city, but the question requires a more general method—finding any city near the Grand Canyon where an American football player was born.

Let's refine the approach:

Step 1: Identify all cities near the Grand Canyon using spatial or location-based properties.
Step 2: For each such city, check if an American football player was born there.
Step 3: Return the city IRIs (and optionally labels) that meet these criteria.

First, let's look for properties that relate locations to "nearby" or "contained by" relationships, as "near travel destination" may not be sufficient for all cities.

I'll search for properties related to "near" or "proximity" in Freebase.

10. Place (fb:base.horseracing.race_results.place): part of Race results schema, links to type Place

[Assistant]
From the search, the most promising properties for finding cities near the Grand Canyon are:

- "Near travel destination" (fb:travel.tourist_attraction.near_travel_destination)
- "Closest city" (fb:skiing.ski_area.closest_city)
- "At or near" (fb:transportation.road_junction.at_or_near)

Since the Grand Canyon is a tourist attraction, let's see if there are any cities or towns linked to it via "Near travel destination" or "Contained by" (for places within the Grand Canyon area).

Let's also check what types of entities are linked to the Grand Canyon via "Contained by" and "Contains" to see if any are cities or towns.

I'll list the objects for "Contains" (fb:location.location.contains) for the Grand Canyon.

[Assistant]
The "Contains" property links the Grand Canyon to various locations, but most are specific buildings or areas, not cities. However, "North Rim, Arizona" (fb:m.0488s92) and "Grand Canyon Village Historic District" (fb:m.03c7cq6) could be relevant.

Let's check if "North Rim, Arizona" and "Grand Canyon Village Historic District" are cities or towns, or if they are contained by a city/town entity.

I'll check what entities "North Rim, Arizona" (fb:m.0488s92) and "Grand Canyon Village Historic District" (fb:m.03c7cq6) are contained by, using the "Contained by" property.

"Grand Canyon Village" (fb:m.0qnxr) is a US Census Designated Place, which is a type of populated place similar to a town or city.

Now, let's generalize the approach:
- Find all populated places (cities, towns, villages, census designated places) that are "contained by" or "near" the Grand Canyon.
- For each such place, check if an American football player was born there.

Let's search for all entities that are "contained by" the Grand Canyon (fb:m.0cns5) and are of type city, town, village, or census designated place.

[Assistant]
From the above, we have identified several populated places in Coconino County, Arizona, near or within the Grand Canyon area:
- Grand Canyon Village (fb:m.0qnxr) — US Census Designated Place
- Tusayan (fb:m.0qp1r) — City/Town/Village
- North Rim, Arizona (fb:m.0488s92) — Area within Grand Canyon

Let's focus on Grand Canyon Village and Tusayan as the most likely candidates for "city near the Grand Canyon."

Now, let's check if any American football players were born in these places. We'll use the "place of birth" property and the "American football player" profession.

I'll write a query to find any American football player born in Grand Canyon Village or Tusayan.

[Tool] Got no rows and 2 columns

[Assistant]
No American football players were found to be born in Grand Canyon Village or Tusayan, the two main populated places near the Grand Canyon.

Let's expand the search to include other nearby cities in Coconino County, such as Flagstaff (fb:m.0fsv2), Williams (fb:m.0qp23), Page (fb:m.0qn_y), and Fredonia (fb:m.0qnxc), which are all relatively close to the Grand Canyon and often considered "gateway" cities.

I'll write a query to check if any American football players were born in these cities.

Feedback (status=refine):
The query is on the right track by filtering for cities near the Grand Canyon and checking for American football players born there. However, the query only returns the city IRIs and not the names of the players, which are referenced in the answer. To fully support the answer, the query should also return the IRIs (and optionally labels) of the players born in each city. This would allow for verification that, for example, Amos Marsh was born in Williams, and Donnie Hickman and Ray Polk were born in Flagstaff. Please refine the query to include the players along with the cities.

[Assistant]
Thank you for the feedback. To fully support the answer and allow for verification, the query should return both the IRIs of the cities and the American football players born there, and optionally their labels for human readability.

I will refine the query to:
- Return the city IRI and label
- Return the player IRI and label

Here is the improved 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.

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 the country with the Iranian Rial form of currency, what is the present form of government?

[Assistant]
Let's break down the question:

1. We need to identify the country that uses the Iranian Rial as its currency.
2. For that country, we need to find its present form of government.

Step 1: Search for the entity "Iranian Rial" in Freebase to find its currency entity.

[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:
freebase at http://galera:7002

You can use the following SPARQL prefixes implicitly in all functions:
fb: <http://rdf.freebase.com/ns/
fbkey: <http://rdf.freebase.com/key/
rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#

wikibase: <http://wikiba.se/ontology#
qb: <http://purl.org/linked-data/cube#
void: <http://rdfs.org/ns/void#

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.
