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 are the church buildings located in Normandy, along with the item of the places they are located in and their images?

[Assistant] To answer this question, I need to find church buildings located in Normandy. I will start by searching for the entity "Normandy" to get its Wikidata identifier. Then, I will find church buildings located in that region and retrieve their locations and images.

[Assistant] There are two main entities for Normandy as a region in France: wd:Q18677875 and wd:Q15878. I will use wd:Q15878 as it is the more general geographical and cultural region of France. Next, I will find church buildings located in this region. To do this, I will search for properties related to location for church buildings.

Top 10 entity alternatives:
1. church building, also known as christian temple, church, church meetinghouse, kirk, meetinghouse (wd:Q16970): building for Christian worship

10. Russian Orthodox church building, also known as church building (wd:Q114785346): place of worshop associated with the Russian Orthodox Church

[Assistant] The entity "church building" (wd:Q16970) represents buildings for Christian worship. I will now construct a SPARQL query to find church buildings (wd:Q16970) located in Normandy (wd:Q15878) along with their locations and images.

[Tool] Got no rows and 5 columns

[Assistant] The query returned no results. It seems that using property P276 (location) for church buildings and then filtering locations by administrative territorial entity Normandy (wd:Q15878) did not yield results. I will try another approach by using the property "located in the administrative territorial entity" (wdt:P131) directly for church buildings to check if that yields results. I will also remove the label service and use optional rdfs:label for labels.

[Tool] Got no rows and 5 columns

[Assistant] The query using property P131 (located in the administrative territorial entity) also returned no results. It is possible that the church buildings are not directly linked to locations within Normandy using P131. I will try a broader approach by checking if the church buildings are located in any place that is part of Normandy using the property "located in the present-day administrative territorial entity" (wdt:P3842) or "located in the administrative territorial entity" (wdt:P131) with a recursive path. I will also try to find church buildings located in any place that has Normandy as an ancestor in the administrative territorial hierarchy.

[Tool] Got no rows and 5 columns

[Assistant] The query still returned no results. It seems that the direct properties for location or administrative territorial entity for church buildings in Normandy are not well populated in the dataset. I will try a different approach by searching for churches (instance of church building or subclass) that have a coordinate location (P625) within the geographical boundaries of Normandy. To do this, I will first find the coordinate location or geographical shape of Normandy and then find church buildings within that area.

Got 1 row and 3 columns:
| subject              | property                       | object                                      |

| Normandy (wd:Q15878) | coordinate location (wdt:P625) | POINT(-0.436644 49.122339) (geo:wktLiteral) |

[Assistant] Normandy (wd:Q15878) has a coordinate location with the point (-0.436644 49.122339). This is a single point, not a polygon or area. I will try to find the administrative territorial entities (e.g., communes, departments) that are part of Normandy and then find church buildings located in those entities.

[Tool] Got no rows and 3 columns

[Assistant] There are no direct subdivisions (P150) listed for Normandy (wd:Q15878). I will try the other Normandy entity (wd:Q18677875) to see if it has subdivisions.

[Tool]
Got 5 rows and 3 columns:
| subject                 | property                                                  | object                     |

| Normandy (wd:Q18677875) | contains the administrative territorial entity (wdt:P150) | Seine-Maritime (wd:Q12758) |
| Normandy (wd:Q18677875) | contains the administrative territorial entity (wdt:P150) | Calvados (wd:Q3249)        |
| Normandy (wd:Q18677875) | contains the administrative territorial entity (wdt:P150) | Manche (wd:Q12589)         |
| Normandy (wd:Q18677875) | contains the administrative territorial entity (wdt:P150) | Orne (wd:Q12679)           |
| Normandy (wd:Q18677875) | contains the administrative territorial entity (wdt:P150) | Eure (wd:Q3372)            |

[Assistant] The entity Normandy (wd:Q18677875) has subdivisions which are administrative territorial entities: Seine-Maritime (wd:Q12758), Calvados (wd:Q3249), Manche (wd:Q12589), Orne (wd:Q12679), and Eure (wd:Q3372). I will now find church buildings located in these subdivisions and retrieve their locations and images.

[Tool] Got no rows and 5 columns

[Assistant] The query returned no results again. It seems that the direct property P131 (located in the administrative territorial entity) for church buildings is not well populated for these subdivisions either. I will try to find church buildings that have coordinate locations (P625) and then check if their coordinates fall within the bounding box of Normandy or its subdivisions. However, since I cannot perform complex geospatial queries here, I will try a simpler approach: find church buildings with coordinate locations and filter those that have a location or administrative territorial entity that is one of the subdivisions of Normandy or the subdivisions' subdivisions. I will try to find locations that are part of the subdivisions of Normandy and then find church buildings located in those locations.

Feedback (status=done):
The answer correctly lists church buildings located in Normandy along with their locations and images, as requested by the user. The SPARQL query properly retrieves churches (instance of Q16970) located in specified communes of Normandy, includes their images if available, and fetches labels in English. The results match the user's question, and the presentation is clear and complete. No further refinement is necessary.

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 are the architectural structures within a 5 km radius of the coordinates (13.5812565, 52.5153623), along with their latitude and longitude?

[Assistant]
To answer this question, I need to identify architectural structures near the given coordinates (13.5812565, 52.5153623) within a 5 km radius and retrieve their latitude and longitude.

Step 1: Identify the property for architectural structures in Wikidata.
Step 2: Use the coordinates and radius to find architectural structures within 5 km.
Step 3: Retrieve the latitude and longitude of these structures.

I will start by searching for the entity or class that represents architectural structures in Wikidata.

[Tool]
Top 10 entity alternatives:
1. architectural structure, also known as designed structure, structures in architecture, structures, structure in architecture, structure (wd:Q811979): human-designed and -made structure
2. architectural structure (wd:L31083-S2)
3. architectural design, also known as architectural structure design (wd:Q3922674): design of buildings and their environments
4. fictional architectural structure (wd:Q63959448): architectural structure which only exists in a work of fiction
5. building; architectural structure (wd:L39822-S1)
6. an architectural structure (wd:L1372925-S1)
7. dome-like architectural structure (wd:L318962-S1)
8. art museum architectural structure (wd:Q129633202)
9. Prinknash Abbey architectural structure (wd:Q131456842)
10. type of architectural structure (wd:Q131733833)

[Assistant]
The entity "architectural structure" in Wikidata is represented by wd:Q811979. This entity corresponds to human-designed and -made structures.

Next, I will construct a SPARQL query to find architectural structures (instances of or subclasses of wd:Q811979) within a 5 km radius of the coordinates (13.5812565, 52.5153623). I will also retrieve their latitude and longitude. I will use the geospatial functions available in Wikidata to filter by distance.

[Tool]
SPARQL execution failed:
Error while executing a SERVICE request to <http://wikiba.se:80/ontology#around>: SERVICE responded with HTTP status code: 301, Moved Permanently. First 100 bytes of the response: '<html>
<head><title>301 Moved Permanently</title></head>
<body>
<center><h1>301 Moved Permanently'

[Assistant]
The query failed because the SERVICE wikibase:around is not supported in this endpoint. I will try an alternative approach using the geof:distance function to filter architectural structures within 5 km radius.

I will rewrite the query to:
- Select architectural structures (wd:Q811979)
- Get their coordinates
- Calculate the distance to the given point using geof:distance
- Filter results within 5 km
- Return the structure, label, latitude, and longitude

[Tool]
SPARQL execution failed:
Invalid SPARQL query: Prefix uom was not registered using a PREFIX declaration

[Assistant]
The query failed because the prefix "uom" for units of measure was not declared. I will add the prefix declaration for "uom" and retry the query.

Prefix for uom is usually: PREFIX uom: <http://www.opengis.net/def/uom/OGC/1.0/>

[Tool]
SPARQL execution failed:
Unsupported unit of measurement for distance.. In file "/qlever/src/util/GeoSparqlHelpers.cpp " at line 72

[Assistant]
The query failed because the unit of measurement "uom:metre" is not supported for the geof:distance function in this endpoint.

I will try the query without specifying the unit, assuming the default unit is meters, and see if it works.

[Assistant]
The query returned architectural structures, but the locations are not within the 5 km radius of the given coordinates (13.5812565, 52.5153623). It seems the geof:distance function might not be working as expected for filtering by distance.

I will try a different approach by using the coordinates property (wdt:P625) and filtering by latitude and longitude ranges that correspond approximately to a 5 km radius around the given point.

Latitude range: 52.5153623 ± ~0.045 (approx 5 km)
Longitude range: 13.5812565 ± ~0.06 (approx 5 km)

I will rewrite the query with these bounding box filters.

Feedback (status=refine):
The answer provides a list of architectural structures with their coordinates, which is relevant to the question. However, the SPARQL query uses simple bounding box filters on latitude and longitude instead of a proper radius filter (e.g., using a geospatial distance function). This means the results are within a rectangular bounding box, not strictly within a 5 km radius. Also, the query returns some duplicate entries (e.g., Georg-Knorr-Platz and Otto-Rosenberg-Platz appear twice). To improve, the query should use a geospatial distance filter to ensure all results are within 5 km of the given coordinates and eliminate duplicates. Additionally, the answer could mention that these are examples and more results exist, which it already does. Overall, the output is sensible but needs refinement in the query to better match the question's radius requirement and to avoid duplicates.

[Assistant]
Thank you for the feedback. I will refine the query to:
- Use a geospatial distance filter to ensure all results are strictly within a 5 km radius of the given coordinates.
- Eliminate duplicate entries by using DISTINCT.
- Retrieve architectural structures with their latitude and longitude.

Since the previous attempt to use geof:distance with units failed, I will try again without specifying units and use DISTINCT to avoid duplicates.

[Assistant]
The query still returns architectural structures that are far from the given coordinates, indicating the geof:distance function might not be working correctly for filtering by radius in this endpoint.

Given this limitation, the best reliable approach is to use the bounding box filter combined with DISTINCT to avoid duplicates. This approach ensures the results are geographically close, though not strictly within a 5 km radius.

I will finalize the query with DISTINCT and bounding box filters for latitude and longitude to provide relevant architectural structures near the coordinates.

Feedback (status=refine):
The SPARQL query correctly retrieves architectural structures within a bounding box around the given coordinates and includes their latitude and longitude. However, the query uses a rectangular bounding box filter instead of a true 5 km radius filter, which may include points outside the actual 5 km radius and exclude some within it. To improve accuracy, the query should use a geospatial distance function to filter structures within a 5 km radius of the given coordinates. Additionally, the answer lists some structures but does not clarify that the list is partial and that more results exist. It would be better to explicitly mention that the results are examples and that the query can return more. Overall, the approach is sensible but can be refined for better precision and clarity.

[Assistant]
Thank you for the feedback. I understand the importance of using a true geospatial distance filter to ensure accuracy within a 5 km radius. However, due to limitations in the endpoint's support for geospatial functions with units, the bounding box approach is the best feasible approximation here.

I will:
- Use DISTINCT to avoid duplicates.
- Use the bounding box filter as an approximation for the 5 km radius.
- Explicitly mention in the answer that the results are examples and more results exist.
- Clarify the limitation regarding the radius filter.

I will finalize the answer 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] What are the countries that are members of the United Nations, along with their capitals, populations, area sizes, heads of state, images of the heads of state, currencies, flag images, and coordinate locations (all only if available)?

[Assistant]
To answer this question, I need to identify the entity for the United Nations and the property that indicates membership in the United Nations. Then I will find the countries that are members of the United Nations. For each country, I will retrieve the capital, population, area size, head of state, image of the head of state, currency, flag image, and coordinate location if available.

Step 1: Identify the entity for the United Nations.
Step 2: Identify the property for membership in the United Nations.
Step 3: Retrieve countries that are members of the United Nations.
Step 4: Retrieve the requested information for each country.

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

10. award received, also known as win, winner of, recognition title, received award, prize received (wd:P166 as p/wdt): award or recognition received by a person, organization or creative work

No other items found

[Assistant]
The search for a direct property indicating membership in the United Nations did not return a clear property for "member of" or "membership" related to the United Nations entity. However, I know that the property "member of" (wdt:P463) is commonly used to indicate membership in organizations.

I will now query for countries that are members of the United Nations using the property "member of" (wdt:P463) with the United Nations entity (wd:Q1065). Then I will retrieve the requested information for each country: capital, population, area size, head of state, image of the head of state, currency, flag image, and coordinate location.

The query failed because the SERVICE wikibase:label is not supported by the used QLever SPARQL endpoint. I will rewrite the query without using SERVICE wikibase:label and instead use optional clauses to get the English labels for the entities.

I will now rewrite the query accordingly.

The SPARQL query correctly retrieves the countries that are members of the United Nations along with their capitals, populations, area sizes, heads of state, images of the heads of state, currencies, flag images, and coordinate locations, all as optional information. The query uses appropriate properties and filters labels for English language where applicable. The limit of 100 results is reasonable for demonstration, though it could be increased if needed. The answer summary accurately reflects the query results. Overall, the output is correct and complete for the user's question.
