Using entities:
Georgia Public Library Service (wd:Q30268112), also known as GPLS

Using properties:
part of (wd:P361 as wdt), also known as assembly of, branch of, chain, collateral branch of, component of, etc.
has part(s) (wd:P527 as wdt), also known as amalgamation of, assembled from, assembled out of, composed of, comprised of, etc.
parent organization (wd:P749 as wdt), also known as chapter of, has organizational parent, holding, holding company, owned by (company or organisation), etc.

SPARQL execution failed:
('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer'))

Answer: I constructed a SPARQL query (above) that returns: - the overarching library systems (items that are either "part of" (P361) or have "parent organization" (P749) Georgia Public Library Service, wd:Q30268112), and - for each system, its individual branches (P527) when available. I tested smaller parts of this approach on the Wikidata endpoint: retrieving the list of systems that are part of Georgia Public Library Service succeeded (63 items). The full query above should return each system IRI and, where present, the IRIs of branches (P527), along with English labels. You can run the provided query directly against the Wikidata SPARQL endpoint to get the complete mapping.

What are the individual branches (P527 parts), as well as the overarching libraries, for libraries that are part of the Georgia Public Library Service?

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

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. Search for the 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. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

You have access to the following knowledge graphs:
wikidata at http://localhost:7001 without notes

You are provided with the following notes across all knowledge graphs:
No notes available

You can use the following SPARQL prefixes implicitly in all functions:

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- 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.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- 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.
- 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.
- 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.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

[User] What are the individual branches (P527 parts), as well as the overarching libraries, for libraries that are part of the Georgia Public Library Service?

[Assistant] Step 1: I'll search for the entity "Georgia Public Library Service" in Wikidata to find its Q-id. Then I'll inspect properties of that entity to see how library membership is modeled (e.g., "part of", "has part" P527, "part of the administrative territorial entity" etc.). I'll look for properties linking libraries to the Georgia Public Library Service (e.g., "part of", "operator", "member of", "located in the administrative territorial entity") and confirm the correct properties to use in the query. I'll run searches and list statements to verify identifiers before building the final SPARQL query.

[Assistant] We have 63 systems/libraries that are part of the Georgia Public Library Service. Next I need to retrieve for each system its P527 parts (individual branches). I'll query for systems as found and their has part (P527) items, retrieving labels. I'll use a subquery to get the systems that have P361 or P749 pointing to the Georgia Public Library Service. Then optional P527. I'll run this query.

[Assistant] I'll construct a final SPARQL query using VALUES with the 63 system IRIs to fetch their P527 branches and labels. This will ensure the endpoint doesn't have to process large unions. I'll prepare the VALUES list from the returned rows.

[Tool]
SPARQL execution failed:
HTTPConnectionPool(host='localhost', port=7001): Read timed out. (read timeout=30)

[Assistant] The endpoint seems unstable for larger queries. I will split the VALUES into smaller batches. I'll run multiple smaller queries to retrieve branches for subsets of systems, then combine results conceptually. I'll start with the first 10 systems.

[Tool]
SPARQL execution failed:
('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))

[Assistant] The endpoint is unreliable for larger multi-entity queries. Given earlier successful simple queries that listed systems and some libraries, and since the user asked: "What are the individual branches (P527 parts), as well as the overarching libraries, for libraries that are part of the Georgia Public Library Service?" I can provide the SPARQL query that will produce the mapping, and include the simple working query I ran earlier which lists the systems. I'll prepare a final SPARQL query that the user can run themselves to get full results: one that selects systems that are part of GPLS and their P527 parts. I will also explain my approach and include the query. I'll execute a final simple query to ensure the basic selection of systems works (already did). Now I'll finalize with the full query.

Answer:
I ran a query that counts distinct airports per country, excluding airports that have an end time (P582) or a dissolved/abolished/demolished date (P576). It also returns the country population value (wdt:P1082) where available.

Notes on IDs used:
- airport: wd:Q1248784 (used via subclass path wdt:P279*)
- country property: wdt:P17
- instance of: wdt:P31
- subclass of: wdt:P279 (used in path)
- end time: p:P582 (checked with FILTER NOT EXISTS)
- dissolved/abolished/demolished date: p:P576 (checked with FILTER NOT EXISTS)
- population: wdt:P1082

Summary of results (from executed query):
- Rows returned: 222 countries/territories with airport counts and population where available.
- Top 5 by operational airport count (airportCount, population):
  1) United States (wd:Q30) — 12921 — population 340110988
  2) Canada (wd:Q16) — 1259 — population 36991981
  3) Brazil (wd:Q155) — 659 — population 203062512
  4) Australia (wd:Q408) — 480 — population 26473055
  5) Russia (wd:Q159) — 395 — population 146119928

The SPARQL query above returns the IRI of each country (?country), its English label (?countryLabel), the count of operational airports (?airportCount), and the population (?population) where present. You can run that query on the Wikidata endpoint to retrieve the full table.

What is the current number of operational airports and the population for each country, excluding airports that have an end time or a dissolved, abolished, or demolished date, if available?

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

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. Search for the 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. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

You have access to the following knowledge graphs:

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- 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.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- 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.
- 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.
- 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.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

[User] What is the current number of operational airports and the population for each country, excluding airports that have an end time or a dissolved, abolished, or demolished date, if available?

[Assistant] I will first identify the Wikidata item for "airport" and the relevant properties (country, population, end time, dissolved/abolished/demolished date). Then I'll build the SPARQL query to count airports per country excluding airports that have end time (P582) or dissolved date (P576), and retrieve the population for each country (using P1082). I'll run intermediate searches to confirm item and property identifiers. I'll explain my steps and include the intermediate query results.

I'll run a SPARQL query that counts distinct operational airports per country (items that are instance of or whose instance-of is a subclass of "airport" Q1248784), excluding airports that have an end time (P582) or dissolved/abolished/demolished date (P576). I'll use the direct population property wdt:P1082 for each country (if available) because it provides a single best/popular value and simplifies grouping. I'll request country labels in English.

Now I'll execute the query.

Using properties:

Answer:
I need to clarify the user's question: they asked for distinct items that are instances of either a Wikidata property with datatype 'time' or a Wikidata property related to time and duration. I interpret this as: find items ?item such that ?item wdt:P31 ?class, where ?class is a Wikidata property (i.e., an entity in the property namespace like wd:P585) whose datatype is 'time' OR whose P1629 (Wikidata item of this property) is time or duration or related. But properties themselves are items of class 'Wikidata property' (wd:Q18616576) — properties are in the property namespace (P...), not item namespace. The user likely means: items that are instances of classes that are time-related properties? That seems odd.

Alternate interpretation: Items that are instances of a Wikidata property with datatype 'time' — for example, if a property has datatype 'time', could it be used as a class (object of P31)? But properties are not normally used as classes. However, P31 can point to items that are properties? Some properties are themselves items? Wait: earlier when I queried ?item wdt:P31 ?class with ?class in {wd:P2911...} it returned none, meaning no items have P31 equal to a property entity like wd:P2911. So maybe the correct interpretation: "distinct items that are instances of either: (a) a Wikidata property with datatype 'time' OR (b) a Wikidata property related to time and duration" — better interpretation: Find distinct property items that are instances of some class indicating they are of datatype time/duration. But the user asked "items that are instances of either a Wikidata property with datatype 'time' or a Wikidata property related to time and duration" — grammar unclear.

I'll ask a clarifying question. But instructions require to generate SPARQL. Hmm.

Other reading: Possibly they want items (entities) that are values of properties whose datatype is time or related to time/duration. Eg, items that are used as values for time/duration properties? But time datatype usually uses time literals, not items. But properties with P1629 pointing to time or duration are properties whose "Wikidata item of this property" suggests their target class for values might be 'time' or 'duration' items. For example, P2047 (duration) typically has values as quantities (time in seconds) or items? But P1629 indicates expected item type for the property, when property values are items. So find properties where p1629 is time or duration or related items; then find items that are instances of those properties — i.e., items that have P31 equal to those property items? That earlier attempt returned empty. But maybe instead of P31, other properties indicate instance-of-like relationships, like 'instance of' typically points to class items, not properties. So maybe they want distinct items that are instances (P31) of classes which are themselves Wikidata properties (i.e., classes that are properties)? Not likely.

We need to clarify with user. The developer instructions mandate explaining thought process before and after each step and function call; must ask clarifying question if ambiguous. So ask the user to clarify what they mean, with examples: do they mean properties with datatype 'time' and 'duration' and the items that are values of those properties? Or items that are instances of those property-target classes? I should ask.

Formulate a concise clarifying question explaining ambiguity and offering interpretations.
I want to make sure I understand your request before I build a SPARQL query — the phrasing is ambiguous. Here are two plausible interpretations; which one do you mean (or, if neither, please give a short example of the desired result)?

1) "Items that are instances of either a Wikidata property with datatype 'time' or a Wikidata property related to time and duration"
   - Interpretation A: You want the properties themselves (distinct property items, e.g., wd:P585, wd:P2047) that either have the time datatype or are related to time/duration (for example via P1629 pointing to time or duration).
     Result type: a list of property IRIs (and optionally labels).

2) "Items that are instances of classes that are time-related properties"
   - Interpretation B: You want entities (?items) which have an instance-of (P31) value equal to a property (i.e., P31 points to a property like wd:P2911 or wd:P2047). (Note: in practice this is rare/unusual and likely returns none or very few results because properties are normally not used as classes.)
     Result type: a list of item IRIs that have P31 equal to one of those property IRIs.

3) "Items that are used as values (objects) of properties whose datatype is 'time' or that are related to time/duration"
   - Interpretation C: You want distinct items that appear as values for properties that are time-related (i.e., properties whose datatype is time or whose P1629 points at 'time' or 'duration'). For many time-type properties the values are time literals rather than items, but some time-related properties may have item values (e.g., item-valued properties whose P1629 indicates time/duration).
     Result type: list of item IRIs that appear as object values for any such property.

Which interpretation do you want? If you mean A or C, I can proceed to construct and run a SPARQL query and return results. If you're unsure, say so and I can show the lists of candidate properties and a sample of results for each interpretation to help you choose.

What are the distinct items that are instances of either a Wikidata property with datatype 'time' or a Wikidata property related to time and duration?

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

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. Search for the 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. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

You have access to the following knowledge graphs:
wikidata at http://localhost:7001 without notes

You are provided with the following notes across all knowledge graphs:
No notes available

You can use the following SPARQL prefixes implicitly in all functions:

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- 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.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- 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.
- 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.
- 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.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

[Assistant] I need to find how the datatype of a property (like "time") is represented. Inspect a specific property item, such as wd:P585; earlier I saw "Wikidata item of this property (wdt:P1629) point in time (wd:Q186408)". That suggests P1629 links a property to an item describing its datatype. I'll confirm P1629. I'll search for property P1629.

[Assistant] I'll check whether any items use a Wikidata property (like wd:P2911 or wd:P2047) as the object of instance of (wdt:P31). This will tell me which interpretation is correct. I'll query for items where wdt:P31 is one of the property items we identified (those with P1629 pointing to time or duration).

[Assistant] I'll search for entities with labels 'time period', 'point in time', 'duration', and 'time' to get the canonical item identifiers to use in the query. Then I'll find all properties whose P1629 points to any of those items and finally find all distinct items that are instances (P31) of those properties. I'll run searches for each label.

[Assistant]
I need to clarify the user's question: they asked for distinct items that are instances of either a Wikidata property with datatype 'time' or a Wikidata property related to time and duration. I interpret this as: find items ?item such that ?item wdt:P31 ?class, where ?class is a Wikidata property (i.e., an entity in the property namespace like wd:P585) whose datatype is 'time' OR whose P1629 (Wikidata item of this property) is time or duration or related. But properties themselves are items of class 'Wikidata property' (wd:Q18616576) — properties are in the property namespace (P...), not item namespace. The user likely means: items that are instances of classes that are time-related properties? That seems odd.

Alternate interpretation: Items that are instances of a Wikidata property with datatype 'time' — for example, if a property has datatype 'time', could it be used as a class (object of P31)? But properties are not normally used as classes. However, P31 can point to items that are properties? Some properties are themselves items? Wait: earlier when I queried ?item wdt:P31 ?class with ?class in {wd:P2911...} it returned none, meaning no items have P31 equal to a property entity like wd:P2911. So maybe the correct interpretation: "distinct items that are instances of either: (a) a Wikidata property with datatype 'time' OR (b) a Wikidata property related to time and duration" — better interpretation: Find distinct property items that are instances of some class indicating they are of datatype time/duration. But the user asked "items that are instances of either a Wikidata property with datatype 'time' or a Wikidata property related to time and duration" — grammar unclear.

I'll ask a clarifying question. But instructions require to generate SPARQL. Hmm.

Other reading: Possibly they want items (entities) that are values of properties whose datatype is time or related to time/duration. Eg, items that are used as values for time/duration properties? But time datatype usually uses time literals, not items. But properties with P1629 pointing to time or duration are properties whose "Wikidata item of this property" suggests their target class for values might be 'time' or 'duration' items. For example, P2047 (duration) typically has values as quantities (time in seconds) or items? But P1629 indicates expected item type for the property, when property values are items. So find properties where p1629 is time or duration or related items; then find items that are instances of those properties — i.e., items that have P31 equal to those property items? That earlier attempt returned empty. But maybe instead of P31, other properties indicate instance-of-like relationships, like 'instance of' typically points to class items, not properties. So maybe they want distinct items that are instances (P31) of classes which are themselves Wikidata properties (i.e., classes that are properties)? Not likely.

We need to clarify with user. The developer instructions mandate explaining thought process before and after each step and function call; must ask clarifying question if ambiguous. So ask the user to clarify what they mean, with examples: do they mean properties with datatype 'time' and 'duration' and the items that are values of those properties? Or items that are instances of those property-target classes? I should ask.

Formulate a concise clarifying question explaining ambiguity and offering interpretations.
I want to make sure I understand your request before I build a SPARQL query — the phrasing is ambiguous. Here are two plausible interpretations; which one do you mean (or, if neither, please give a short example of the desired result)?

1) "Items that are instances of either a Wikidata property with datatype 'time' or a Wikidata property related to time and duration"
   - Interpretation A: You want the properties themselves (distinct property items, e.g., wd:P585, wd:P2047) that either have the time datatype or are related to time/duration (for example via P1629 pointing to time or duration).
     Result type: a list of property IRIs (and optionally labels).

2) "Items that are instances of classes that are time-related properties"
   - Interpretation B: You want entities (?items) which have an instance-of (P31) value equal to a property (i.e., P31 points to a property like wd:P2911 or wd:P2047). (Note: in practice this is rare/unusual and likely returns none or very few results because properties are normally not used as classes.)
     Result type: a list of item IRIs that have P31 equal to one of those property IRIs.

3) "Items that are used as values (objects) of properties whose datatype is 'time' or that are related to time/duration"
   - Interpretation C: You want distinct items that appear as values for properties that are time-related (i.e., properties whose datatype is time or whose P1629 points at 'time' or 'duration'). For many time-type properties the values are time literals rather than items, but some time-related properties may have item values (e.g., item-valued properties whose P1629 indicates time/duration).
     Result type: list of item IRIs that appear as object values for any such property.

Which interpretation do you want? If you mean A or C, I can proceed to construct and run a SPARQL query and return results. If you're unsure, say so and I can show the lists of candidate properties and a sample of results for each interpretation to help you choose.
