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] Find the locations of maypoles that are outside both Germany and Austria.

[Assistant]
Let's break down the question:

1. We are looking for maypoles. In OpenStreetMap, maypoles are typically tagged with "maypole" (e.g., osm2rdfkey:maypole).
2. We need their locations.
3. We want only those outside both Germany and Austria.

Step 1: Let's search for how maypoles are represented in OSM.

[Tool]
Top 10 entity alternatives:
1. Maypole (osmnode:3479342915)
2. Maypole (osmnode:577419993)
3. Maypole (osmnode:11163227642)
4. Maypole (osmnode:11281029049)
5. Maypole (osmnode:11964323647)
6. Maypole (osmnode:12212922414): theatre
7. Maypole (osmnode:12511943246)
8. Maypole (osmnode:1967528220)
9. Maypole (osmnode:2255951131)
10. Maypole (osmnode:2504037594)

[Assistant]
I see that "maypole" locations are represented as nodes in OSM, and they are likely tagged with a key such as "maypole=yes" or similar.

Step 2: To generalize, let's check which property is used to indicate a maypole, so we can select all maypoles, not just specific nodes.

I'll search for properties related to "maypole".

[Tool]
Top 10 property alternatives:
1. tree:maypole (<https://www.openstreetmap.org/wiki/Key:tree:maypole>)
2. flagpole (osmkey:flagpole)
3. pole (osmkey:pole)
4. ref:pole (<https://www.openstreetmap.org/wiki/Key:ref:pole>)
5. disused:pole (<https://www.openstreetmap.org/wiki/Key:disused:pole>)
6. pole:location (<https://www.openstreetmap.org/wiki/Key:pole:location>)
7. flagpole:type (<https://www.openstreetmap.org/wiki/Key:flagpole:type>)
8. abandoned:pole (<https://www.openstreetmap.org/wiki/Key:abandoned:pole>)
9. was:pole (<https://www.openstreetmap.org/wiki/Key:was:pole>)
10. pole:medium (<https://www.openstreetmap.org/wiki/Key:pole:medium>)

[Tool] Got no rows and 3 columns

[Assistant]
The property "tree:maypole" exists, but there are no results for it in the knowledge graph. However, the search for entities returned several nodes labeled as "Maypole". This suggests that maypoles might be tagged with a different key, possibly "maypole" itself.

Let me check the tags for one of the maypole nodes (e.g., osmnode:3479342915) to see how it is represented.

[Assistant]
It appears that the maypole node does not have a specific "maypole" property, but is instead identified by its label ("Maypole"). This suggests that maypoles may not have a unique key in OSM, but are mapped as nodes with the name "Maypole".

Given this, the best approach is to select all nodes with the label "Maypole" (rdfs:label "Maypole") and then filter out those that are within Germany or Austria.

Next, let's find the IRIs for Germany and Austria in the OSM knowledge graph.

SPARQL execution failed:
Tried to allocate 245.4 GB, but only 22.5 GB were available. Clear the cache or allow more memory for QLever during startup

[Assistant]
The previous query was too broad and caused a memory error. To optimize, I should:

- Avoid retrieving all maypoles at once.
- Use a more selective approach, possibly by filtering maypoles that intersect with any country, and then excluding Germany (osmrel:51477) and Austria (osmrel:16239).
- Limit the number of results for testing.

I'll try a more focused query, retrieving maypoles labeled "Maypole" and showing their intersected country, but only if that country is not Germany or Austria. I'll also add a LIMIT to keep the result manageable.

SPARQL execution failed:
Tried to allocate 87.7 GB, but only 22.5 GB were available. Clear the cache or allow more memory for QLever during startup

[Assistant]
The query is still too broad and causes a memory error. This is likely due to the high number of nodes with the label "Maypole" and the spatial intersection checks.

To further optimize, I will:
- Only retrieve maypoles that have a direct spatial intersection with a country other than Germany or Austria.
- Limit the number of returned triples at every step.
- Avoid unnecessary OPTIONAL clauses for now.

I'll try a query that just retrieves the first few maypoles labeled "Maypole" and their intersected country, to see if this is feasible.

[Tool] Got no rows and 2 columns

[Assistant]
The query returned no results, which suggests that maypoles labeled "Maypole" do not have a direct spatial intersection with a country entity in the knowledge graph, or the intersection property is not populated for these nodes.

Given this, another approach is to:
- Retrieve all nodes labeled "Maypole" along with their coordinates.
- Exclude those that are within Germany or Austria by checking their spatial intersection, if possible, or by post-processing their coordinates (but post-processing is not allowed per the rules).

Alternatively, I can check if maypoles are tagged with a country property or if their parent administrative boundary can be determined.

Let me check the properties of another maypole node to see if there is any administrative boundary or country information.

[Assistant]
From inspecting several maypole nodes, I see that they have an ogc:sfIntersects property pointing to a country relation (e.g., United Kingdom: osmrel:62149). This means we can select maypoles whose intersected country is not Germany (osmrel:51477) or Austria (osmrel:16239).

Therefore, the correct approach is:
- Select all nodes with rdfs:label "Maypole".
- For each, get the intersected country.
- Filter out those where the country is Germany or Austria.
- Optionally, get their centroid (location).

Here is the final SPARQL query:

Feedback (status=retry):
The SPARQL query failed due to excessive memory usage, likely caused by an inefficient query pattern. Specifically, the use of ogc:sfIntersects between maypoles and all countries is computationally expensive. Additionally, the query assumes that maypoles have the rdfs:label 'Maypole', which may not be accurate for all relevant items in OSM, as they may use tags or other labels. To improve, consider using more specific OSM tags for maypoles (e.g., man_made=maypole), and directly filter by country tags or properties rather than spatial intersection. Also, retrieve only the IRIs as required, and use OPTIONAL only for non-essential data. The query should be reworked for efficiency and correctness.

[Assistant]
Thank you for the feedback. Here’s how I’ll proceed based on your suggestions:

1. I’ll search for the correct OSM tag for maypoles (likely man_made=maypole).
2. I’ll look for a property that indicates the country directly (e.g., addr:country or is_in:country), rather than using spatial intersection.
3. I’ll construct a query that retrieves only the IRIs of maypoles outside Germany and Austria, using efficient triple patterns.

Step 1: Search for the correct property/tag for maypoles in OSM.

Feedback (status=refine):
The query attempts to find maypoles outside Germany and Austria by filtering out those countries, but the use of ogc:sfIntersects ?country is too broad. It returns all geographic entities that intersect with the maypole, including regions, time zones, and administrative areas, not just countries. This results in irrelevant results (e.g., time zones, regions within Germany). The query should be refined to ensure that ?country is actually a country, for example by requiring that it has a property indicating it is a country (such as a specific type or admin_level=2 in OSM). Add a clause to restrict ?country to actual countries, not subregions or other entities.

[Assistant]
Thank you for the feedback. To address this:

- I will restrict ?country to actual countries by requiring that it has admin_level=2 (the OSM convention for countries).
- I will keep the maypole selection as man_made=maypole.
- I will filter out Germany (osmrel:51477) and Austria (osmrel:16239).

Step-by-step plan:
1. Find the property for admin_level and its value for countries.
2. Add a clause so that ?country must have admin_level=2.
3. Filter out Germany and Austria.
4. Return the IRIs of maypoles and their country.

First, let's confirm the property for admin_level.

[Assistant]
It appears that filtering for admin_level=2 directly is not working efficiently, possibly due to datatype issues or the way the data is stored. However, from the previous list, I see that some country entities use the property osmkey:admin_level with the value "2 (xsd:int)".

Given this, I will use a more robust approach:
- For each maypole (man_made=maypole), find intersected entities (?country) that have osmkey:admin_level with any value containing "2".
- Exclude Germany (osmrel:51477) and Austria (osmrel:16239).
- Return the maypole and country IRIs.

Here is the refined query:

[Tool] Stopped generation process


PREFIX osm2rdfkey: <https://osm2rdf.cs.uni-freiburg.de/rdf/key#>
SELECT ?way ?wikidata WHERE {
  ?way osm2rdfkey:wikidata ?wikidata .
  FILTER ( STRSTARTS( STR( ?way ) , "https://www.openstreetmap.org/way/" ) )
}

The OSM-Planet knowledge graph only contains links from OSM entities to Wikidata items (via the osm2rdfkey:wikidata property), but does not contain any properties or statements for Wikidata items themselves. Therefore, it is not possible to check whether a Wikidata item has a reciprocal link back to the OSM way using only this knowledge graph. A full answer would require querying Wikidata for reciprocal links, which is outside the scope of the OSM-Planet KG.

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] Find OpenStreetMap ways linked to a unique Wikidata item where the Wikidata item lacks a reciprocal link back to the OSM way.

[Assistant]
Let's break down the question:

1. We are looking for OpenStreetMap (OSM) ways that are linked to a unique Wikidata item.
2. The Wikidata item does not have a reciprocal link back to the OSM way.

Step-by-step plan:
- First, identify OSM ways that have a Wikidata tag (likely via a property like osm2rdfkey:wikidata).
- Ensure the Wikidata tag is unique for each OSM way (i.e., one-to-one mapping).
- For each such Wikidata item, check if it has a property linking back to the OSM way (reciprocal link). This is often via a property like "OpenStreetMap relation ID", "OpenStreetMap way ID", or a URL property in Wikidata.
- Filter for cases where the reciprocal link is missing.

First, let's search for the property used in OSM for Wikidata links.

[Tool]
Top 10 property alternatives:
1. wikidata (osm2rdfkey:wikidata)
2. wikidata (osmkey:wikidata)
3. description:wikidata (<https://osm2rdf.cs.uni-freiburg.de/rdf/key#description:wikidata>)
4. description:wikidata (<https://www.openstreetmap.org/wiki/Key:description:wikidata>)
5. about:wikidata (<https://www.openstreetmap.org/wiki/Key:about:wikidata>)
6. about:wikidata (<https://osm2rdf.cs.uni-freiburg.de/rdf/key#about:wikidata>)

8. related:wikidata (<https://osm2rdf.cs.uni-freiburg.de/rdf/key#related:wikidata>)
9. content:wikidata (<https://www.openstreetmap.org/wiki/Key:content:wikidata>)
10. content:wikidata (<https://osm2rdf.cs.uni-freiburg.de/rdf/key#content:wikidata>)

[Assistant]
The main property for Wikidata links in OSM is osm2rdfkey:wikidata.

Next, let's confirm the format of the value: it should be a Wikidata Q-ID (e.g., "Q42"). We will check a few example triples for OSM ways with this property to see how the linkage is represented.

[Assistant]
The value is indeed a Wikidata Q-ID (e.g., wd:Q84). However, the examples above are for nodes. We want to focus on OSM ways. Let's filter for subjects that are OSM ways (i.e., IRIs starting with osmway:).

Next, let's find a few examples of OSM ways with a Wikidata tag.

[Tool] Got no rows and 3 columns

[Assistant]
It appears that directly filtering with "osmway:" as a subject prefix did not return results, possibly because the API expects a full IRI rather than a prefix. Instead, let's search for OSM ways with a Wikidata tag by searching for entities with "osmway:" in their IRI and the property osm2rdfkey:wikidata.

Alternatively, let's search for entities with "osmway" in their name to find a sample OSM way entity, and then check its properties.

[Tool] No entity items found

[Assistant] It seems that searching for "osmway" as an entity does not return results, possibly because the search expects more specific names. Let's try searching for a well-known OSM way, such as "Broadway" (a famous street), and see if we can find an OSM way entity with a Wikidata tag.

[Assistant] We have found several OSM way entities for "Broadway" (e.g., osmway:1003870611). Let's check if one of these has a Wikidata tag and inspect its properties to confirm the linkage.

[Assistant]
The OSM way osmway:1003870611 (Broadway) is linked to Wikidata item wd:Q11260 via the property osm2rdfkey:wikidata.

Now, to answer the question, we need to:
1. Find all OSM ways with a unique Wikidata link (osm2rdfkey:wikidata).
2. For each Wikidata item, check if it has a reciprocal link back to the OSM way.

Since the OSM knowledge graph may not contain all Wikidata properties, let's check what properties are available for a Wikidata item (e.g., wd:Q11260) in this KG, to see if reciprocal links are present.

[Tool] Got no rows and 3 columns

[Assistant]
There are no properties for Wikidata items in the OSM knowledge graph. This means the OSM-Planet KG only contains OSM-to-Wikidata links, not Wikidata-to-OSM links.

Therefore, it is not possible to check for the presence or absence of reciprocal links from Wikidata items back to OSM ways using only the OSM-Planet knowledge graph.

I will cancel and explain this limitation.

[Tool] Stopped generation process

[User]
Feedback (status=done):
The explanation is correct. The OSM-Planet knowledge graph only contains links from OSM ways to Wikidata items, but does not contain information about whether the Wikidata item links back to the OSM way. Therefore, it is not possible to answer the question as stated using only the OSM-Planet KG. The SPARQL query provided is the best possible attempt within the limitations of the data, and the explanation accurately describes why a full answer is not possible.

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] Rank mapped roundabouts or circular junctions by how non-circular they are, using a compactness test.

[Assistant]
Let's break down the question:

1. We need to find mapped roundabouts or circular junctions in OpenStreetMap.
2. We need to rank them by how non-circular they are, using a compactness test.
3. Compactness is often measured as (4π * Area) / (Perimeter^2), with 1 being a perfect circle and lower values being less circular.

Step 1: Identify how roundabouts or circular junctions are tagged in OSM. Common tags are:
- junction=roundabout
- highway=mini_roundabout

Step 2: For each roundabout, we need its geometry to compute area and perimeter.

Step 3: Compute compactness for each, and rank by lowest compactness (most non-circular).

First, let's search for the property or tag used for roundabouts in the OSM knowledge graph.
To proceed, I will search for entities related to "roundabout" in the OSM knowledge graph to confirm the tags or properties used for roundabouts or circular junctions.
