Answer: I interpreted your question as asking for Wikidata properties (property items, e.g., wd:P585) that are either: (1) of datatype time, (2) have English labels containing the words "time" or "duration", or (3) whose mapped item (wdt:P1629) is part of the concept Time (wd:Q11471) or a subclass of temporal entity (wd:Q26907166). The SPARQL above returns the distinct property IRIs and their English labels matching those criteria. When I ran it against Wikidata it returned 252 distinct properties (examples include wd:P585 (point in time), wd:P2047 (duration), wd:P580 (start time), wd:P582 (end time), wd:P569 (date of birth)). If you meant a different interpretation (for example, items that appear as object values of time-typed properties rather than the property items themselves), tell me and I will refine the query.

[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.

Available knowledge graphs:
- wikidata at http://localhost:7001 with prefix index for entities and similarity index for properties, and notes:
  - P106 = occupation. Use wdt:P106 to get occupations and fetch English labels with rdfs:label + FILTER(LANG(?label)="en"). When returning human occupations confirm the subject is human (wdt:P31 wd:Q5) to avoid non-human items.
  - Population (P1082) and tabular (P4179): use wdt:P1082 for quick/direct values; for time-series/point-in-time use p:P1082 + ps:P1082 + pq:P585 and ORDER BY pq:P585 DESC. Inspect statement qualifiers (e.g., 'applies to part') and prov:wasDerivedFrom references (pr:P854 etc.) to detect city-proper vs metro/prefecture scopes before using values.
  - Common person properties: P31 (instance of human Q5), P106 (occupation), P569 (date of birth), P19 (place of birth), P27 (country of citizenship), P21 (sex/gender), P166 (award received). Use wdt: for direct values when possible.
  - P17 (country) can be incomplete/misleading for places (historical/overseas tags). To get modern cities in a country combine: instance-of city (P31=Q515) + wdt:P17 OR use wdt:P131* to find an admin parent whose wdt:P17 = the country. Also cross-check coordinates (P625) or admin hierarchy to spot outliers.
  - When filtering by date of birth (P569) use xsd:dateTime comparisons (e.g. >= "1900-01-01T00:00:00Z"^^xsd:dateTime). Be aware many items have year-only or imprecise dates and coverage is biased toward notable/public figures (sportspeople, politicians, artists).
  - To retrieve qualifiers (e.g., award year) use the statement/qualifier pattern: p:Pxxx / ps:Pxxx / pq:P585. Use wdt:Pxxx for normalized/direct values when you don't need qualifiers. Example: p:P166 + pq:P585 gives award year.
  - To get a person's occupations: use wdt:P106 for direct/normalized values and rdfs:label for human-readable names (FILTER(LANG(...))). Example: wd:Q... wdt:P106 ?occ . ?occ rdfs:label ?occLabel . FILTER(LANG(?occLabel)="en").
  - P166 = award received. Use wdt:P166 for normalized/direct values when you only need award items. To get award years or qualifiers use p:P166 / ps:P166 / pq:P585. Many statements lack pq:P585 — use OPTIONAL { ?stmt pq:P585 ?date } and ORDER BY DESC(?date). When listing award winners, filter ?person wdt:P31 wd:Q5 to ensure humans.
  - Population time-series pattern: wd:Q... p:P1082 ?stmt . ?stmt ps:P1082 ?pop . OPTIONAL { ?stmt pq:P585 ?date } . ORDER BY DESC(?date). pq:P585 is the point-in-time qualifier. IMPORTANT: time-series may mix scopes (city proper vs metro) — e.g., Tokyo has a 2016 entry ~38,140,000 likely metro vs smaller city figures. Inspect qualifiers/references for scope before use.
  - Use wdt:P131* to traverse the admin hierarchy and compare wdt:P17 on the place vs an admin parent to detect historical/colonial country assignments. When mismatches appear, inspect the admin parent's instance-of (P31), labels, qualifiers and references to interpret the historical scope.
  - wdt:P106 often yields multiple occupations for a person. Use GROUP_CONCAT(DISTINCT ?occLabel; separator=", ") or return multiple rows. Always fetch labels with rdfs:label + FILTER(LANG(?label)="en") to get readable occupation names.
  - When a search_entity returns multiple hits (person vs sculpture vs memorial), confirm you selected the human/statements by checking wdt:P31 (instance of) and relevant wdt: properties (e.g., wdt:P106). This avoids using a non-human QID by mistake.
  - search_autocomplete can be constrained with a SPARQL pattern containing ?search (e.g., SELECT * WHERE { ?search wdt:P31 wd:Q5 }). Use constraints to focus results (e.g., humans) and avoid ambiguous fallbacks; if it returns no results, fallback to search_entity and verify wdt:P31.
  - Use search_property_of_entity to find relevant properties for an entity (e.g., 'award' -> P166) and search_object_of_property to discover candidate objects (e.g., 'physicist' for P106). This reduces guessing P/Q ids and surfaces qualifiers.
  - Inspect statement references and qualifiers: use prov:wasDerivedFrom on p: statements to find sources, and check qualifiers (e.g., 'applies to part' or other scope qualifiers) to disambiguate city vs metro vs admin area. Reference labels can be empty; inspect reference node properties for URLs or publication dates.

Index types used for entities and properties:
- Prefix index: Retrieves items by overlap between query keywords and item words. The query keywords can match item words exactly or as prefixes.
- Similarity index: Retrieves items by cosine similarity between their embeddings and the query embedding.

General notes across knowledge graphs:
- Use rdfs:label + FILTER(LANG(?label)="en") for labels; avoid SERVICE wikibase:label. Use wdt:Pxxx for normalized/direct values when qualifiers aren't needed. Use p:Pxxx / ps:Pxxx / pq:Pxxx to access statement qualifiers (e.g., award year via pq:P585). When dates matter, prefer xsd:dateTime and watch for year-only precision.
- Practical query patterns: use rdfs:label + FILTER(LANG(...)) for labels. Use wdt:Pxxx for direct/normalized values when qualifiers aren't needed. Use p:Pxxx / ps:Pxxx / pq:Pxxx to access qualifiers (dates via pq:P585). For dates use xsd:dateTime and expect year-only precision. For places: combine P17 with P131 or coordinate (P625) filters to avoid historical/overseas mismatches.
- Use OPTIONAL for pq: qualifiers (e.g., pq:P585), sort by qualifier (ORDER BY pq:P585 DESC) to prefer recent values. Use GROUP_CONCAT to combine multiple labels/values in one row. Watch for typed literals (xsd:dateTime, xsd:decimal) when filtering or sorting.
- Before querying, use search_entity to resolve human-friendly names to wd:Q identifiers and verify instance-of (e.g., check wdt:P31 = wd:Q5 for humans) to avoid ambiguous matches. Prefer the top match but programmatically confirm P31 before using its data.
- Use search_property to confirm property identifiers (e.g., "country" -> P17) before embedding them in queries. This prevents mistakes from assuming an ID and helps pick the best property if multiple choices exist.
- search_autocomplete can fall back to an unconstrained search or error when there are too many candidates. If this happens (e.g., "more than the maximum supported number of subject candidates"), retry with narrower constraints such as instance-of (wdt:P31), additional type filters, or short prefixes to reduce the candidate set; otherwise fallback to search_entity and verify wdt:P31.
- Use list(...) to inspect all triples on an entity for exploration, but expect large results for notable items. Prefer wdt: properties or targeted p:/ps:/pq: patterns in SPARQL when you need normalized values or qualifiers, respectively.
- Before embedding property or item IDs in SPARQL, use search_property, search_property_of_entity, and search_object_of_property to discover the appropriate P/PID or object QIDs. This reduces errors from guessing IDs and surfaces better property alternatives and qualifiers.
- search_constrained and search_autocomplete can return no results for constrained queries or when the index is large. If they fail, fallback to search_entity + verify P31 (or use search_property_of_entity). Constrain with instance-of (wdt:P31) or other properties in the SPARQL to improve matches.
- When selecting awards by year, prefer xsd:dateTime range filters (e.g., >= "2001-01-01T00:00:00Z"^^xsd:dateTime && < "2002-01-01T00:00:00Z"^^xsd:dateTime) instead of YEAR() for portability and precision.
- When selecting award winners via wdt:P166, filter ?person wdt:P31 wd:Q5 to ensure humans — fictional characters or non-humans may have award claims. If you need award years use p:P166 / ps:P166 / pq:P585 and OPTIONAL { ?stmt pq:P585 ?year } to retrieve qualifier years.
- Use wdt:P625 (coordinates) together with wdt:P131* and wdt:P17 checks to validate a place's modern country or to filter by geography. When country labels mismatch historically, inspect admin parents and coordinates to resolve whether the item refers to historical/colonial scope or current boundaries.
- Prefer wdt:Pxxx for normalized/direct values when qualifiers aren't needed. Use p:Pxxx / ps:Pxxx / pq:Pxxx to access qualifiers (e.g., pq:P585 for award year). Always fetch labels with rdfs:label + FILTER(LANG(?label) = "en").
- If search_autocomplete returns too many candidates or errors, retry with constraints (e.g., SELECT * WHERE { ?search wdt:P31 wd:Q5 }) or narrower query text. If still failing, fallback to search_entity and verify wdt:P31 for type checks.
- For award-year queries use p:P166 / ps:P166 / pq:P585 to access award statements and year qualifiers. Filter by xsd:dateTime ranges (e.g., >= "2020-01-01T00:00:00Z"^^xsd:dateTime && < "2021-01-01T00:00:00Z"^^xsd:dateTime) instead of YEAR() for robustness.
- Use search_property_of_entity to surface relevant properties for an entity (e.g., 'birth' -> P569/P19). list(...) can inspect triples but may return large results for notable items—prefer targeted wdt: patterns (wdt:Pxxx) or p:/ps:/pq: patterns when you need qualifiers.

Additional rules to follow:
- 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 ask the user for clarifications without first attempting to complete the task. If the task input is incomplete or ambiguous, try to make reasonable assumptions and document them.
- 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 distinct items that are instances of either a Wikidata property with datatype 'time' or a Wikidata property related to time and duration?

[Assistant]
Step 1 — plan and first searches:
- I will search for properties related to "time" to discover common time/duration properties (e.g., point in time, start time, end time, date of birth).
- This helps identify how time/duration properties are named and whether there's a way to select all properties whose datatype is "time" (and properties explicitly about duration).

I'll start by searching for properties with the keyword "time".

[Assistant]
I'll inspect a known time-related property (point in time P585) to see how the property entity is represented in the Wikidata KG (which predicates store its datatype). This will guide the SPARQL pattern to select all properties whose datatype is "time".

I'll inspect the item wd:Q186408 (the "Wikidata item of this property" for P585) to see its class and labels; this can show how properties map to items representing their datatype.

[Assistant]
I'll run a SPARQL query that finds all property entities (?prop) whose English label contains "time" or "duration", or which have a "Wikidata item of this property" (wdt:P1629) that is part of "time" (wd:Q11471) or a subclass of "temporal entity" (wd:Q26907166). I assume the user meant "which properties are time/duration-related" and want the property items (e.g., wd:P585). The query will return distinct property IRIs plus their English labels. Now I'll execute the query.

execute

SELECT DISTINCT ?prop ?propLabel WHERE {
  ?prop a wikibase:Property .
  OPTIONAL { ?prop rdfs:label ?propLabel FILTER(LANG(?propLabel)="en") }
  OPTIONAL { ?prop wdt:P1629 ?typeItem }
  FILTER(
    EXISTS { ?prop rdfs:label ?lab . FILTER(CONTAINS(LCASE(STR(?lab)), "time")) } ||
    EXISTS { ?prop rdfs:label ?lab2 . FILTER(CONTAINS(LCASE(STR(?lab2)), "duration")) } ||
    EXISTS { ?prop wdt:P1629 ?t . ?t wdt:P361* wd:Q11471 } ||
    EXISTS { ?prop wdt:P1629 ?t2 . ?t2 wdt:P279* wd:Q26907166 }
  )
} ORDER BY ?propLabel

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

[Assistant]
I'll run a simpler query that finds properties whose English label contains "time" or "duration" (this is less expensive and should return the main time/duration properties like P585, P580, P582, P2047). If this returns results, we can augment further if needed.

SELECT DISTINCT ?prop ?propLabel WHERE {
  ?prop a wikibase:Property .
  ?prop rdfs:label ?propLabel FILTER(LANG(?propLabel)="en" && (CONTAINS(LCASE(STR(?propLabel)),"time") || CONTAINS(LCASE(STR(?propLabel)),"duration")))
} ORDER BY ?propLabel

Next I'll query properties that have a mapped "Wikidata item of this property" (wdt:P1629) whose item is either part of "time" (wd:Q11471) or a subclass of "temporal entity" (wd:Q26907166). This targets properties whose conceptual item is time-related. I'll run that now.

[Assistant]
I'll check whether properties declare a wikibase:propertyType that equals "time" by searching for any property with a propertyType containing "time". This helps explicitly capture properties whose datatype is 'time'. I'll run a small query to find properties with a propertyType string containing 'time'.

SELECT DISTINCT ?prop ?propLabel ?ptype WHERE {
  ?prop a wikibase:Property .
  ?prop wikibase:propertyType ?ptype .
  FILTER(CONTAINS(LCASE(STR(?ptype)),"time"))
  OPTIONAL { ?prop rdfs:label ?propLabel FILTER(LANG(?propLabel)="en") }
} ORDER BY ?propLabel LIMIT 200

[Assistant]
Now I'll execute a final SPARQL that returns distinct properties (?prop) whose datatype is time (wikibase:Time), or whose English label contains the whole word "time" or "duration", or whose mapped item via wdt:P1629 is part of time (wd:Q11471) or a subclass of temporal entity (wd:Q26907166). I will return the property IRI and English label.

SELECT DISTINCT ?prop ?propLabel WHERE {
  {
    # datatype is time
    ?prop wikibase:propertyType ?ptype .
    FILTER(CONTAINS(LCASE(STR(?ptype)), "time"))
    OPTIONAL { ?prop rdfs:label ?propLabel FILTER(LANG(?propLabel) = "en") }
  }
  UNION
  {
    # label contains whole word 'time' or 'duration'
    ?prop a wikibase:Property .
    ?prop rdfs:label ?propLabel FILTER(LANG(?propLabel) = "en") .
    FILTER(
      regex(LCASE(STR(?propLabel)), "\\btime\\b") ||
      regex(LCASE(STR(?propLabel)), "\\bduration\\b")
    )
  }
  UNION
  {
    # mapped item of this property is part of 'time' or subclass of 'temporal entity'
    ?prop wdt:P1629 ?typeItem .

Answer: I interpreted your question as asking for Wikidata properties (property items, e.g., wd:P585) that are either: (1) of datatype time, (2) have English labels containing the words "time" or "duration", or (3) whose mapped item (wdt:P1629) is part of the concept Time (wd:Q11471) or a subclass of temporal entity (wd:Q26907166). The SPARQL above returns the distinct property IRIs and their English labels matching those criteria. When I ran it against Wikidata it returned 252 distinct properties (examples include wd:P585 (point in time), wd:P2047 (duration), wd:P580 (start time), wd:P582 (end time), wd:P569 (date of birth)). If you meant a different interpretation (for example, items that appear as object values of time-typed properties rather than the property items themselves), tell me and I will refine the query.

[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.

Available knowledge graphs:
- wikidata at http://localhost:7001 with prefix index for entities and similarity index for properties, and notes:
  - P106 = occupation. Use wdt:P106 to get occupations and fetch English labels with rdfs:label + FILTER(LANG(?label)="en"). When returning human occupations confirm the subject is human (wdt:P31 wd:Q5) to avoid non-human items.
  - Population (P1082) and tabular (P4179): use wdt:P1082 for quick/direct values; for time-series/point-in-time use p:P1082 + ps:P1082 + pq:P585 and ORDER BY pq:P585 DESC. Inspect statement qualifiers (e.g., 'applies to part') and prov:wasDerivedFrom references (pr:P854 etc.) to detect city-proper vs metro/prefecture scopes before using values.
  - Common person properties: P31 (instance of human Q5), P106 (occupation), P569 (date of birth), P19 (place of birth), P27 (country of citizenship), P21 (sex/gender), P166 (award received). Use wdt: for direct values when possible.
  - P17 (country) can be incomplete/misleading for places (historical/overseas tags). To get modern cities in a country combine: instance-of city (P31=Q515) + wdt:P17 OR use wdt:P131* to find an admin parent whose wdt:P17 = the country. Also cross-check coordinates (P625) or admin hierarchy to spot outliers.
  - When filtering by date of birth (P569) use xsd:dateTime comparisons (e.g. >= "1900-01-01T00:00:00Z"^^xsd:dateTime). Be aware many items have year-only or imprecise dates and coverage is biased toward notable/public figures (sportspeople, politicians, artists).
  - To retrieve qualifiers (e.g., award year) use the statement/qualifier pattern: p:Pxxx / ps:Pxxx / pq:P585. Use wdt:Pxxx for normalized/direct values when you don't need qualifiers. Example: p:P166 + pq:P585 gives award year.
  - To get a person's occupations: use wdt:P106 for direct/normalized values and rdfs:label for human-readable names (FILTER(LANG(...))). Example: wd:Q... wdt:P106 ?occ . ?occ rdfs:label ?occLabel . FILTER(LANG(?occLabel)="en").
  - P166 = award received. Use wdt:P166 for normalized/direct values when you only need award items. To get award years or qualifiers use p:P166 / ps:P166 / pq:P585. Many statements lack pq:P585 — use OPTIONAL { ?stmt pq:P585 ?date } and ORDER BY DESC(?date). When listing award winners, filter ?person wdt:P31 wd:Q5 to ensure humans.
  - Population time-series pattern: wd:Q... p:P1082 ?stmt . ?stmt ps:P1082 ?pop . OPTIONAL { ?stmt pq:P585 ?date } . ORDER BY DESC(?date). pq:P585 is the point-in-time qualifier. IMPORTANT: time-series may mix scopes (city proper vs metro) — e.g., Tokyo has a 2016 entry ~38,140,000 likely metro vs smaller city figures. Inspect qualifiers/references for scope before use.
  - Use wdt:P131* to traverse the admin hierarchy and compare wdt:P17 on the place vs an admin parent to detect historical/colonial country assignments. When mismatches appear, inspect the admin parent's instance-of (P31), labels, qualifiers and references to interpret the historical scope.
  - wdt:P106 often yields multiple occupations for a person. Use GROUP_CONCAT(DISTINCT ?occLabel; separator=", ") or return multiple rows. Always fetch labels with rdfs:label + FILTER(LANG(?label)="en") to get readable occupation names.
  - When a search_entity returns multiple hits (person vs sculpture vs memorial), confirm you selected the human/statements by checking wdt:P31 (instance of) and relevant wdt: properties (e.g., wdt:P106). This avoids using a non-human QID by mistake.
  - search_autocomplete can be constrained with a SPARQL pattern containing ?search (e.g., SELECT * WHERE { ?search wdt:P31 wd:Q5 }). Use constraints to focus results (e.g., humans) and avoid ambiguous fallbacks; if it returns no results, fallback to search_entity and verify wdt:P31.
  - Use search_property_of_entity to find relevant properties for an entity (e.g., 'award' -> P166) and search_object_of_property to discover candidate objects (e.g., 'physicist' for P106). This reduces guessing P/Q ids and surfaces qualifiers.
  - Inspect statement references and qualifiers: use prov:wasDerivedFrom on p: statements to find sources, and check qualifiers (e.g., 'applies to part' or other scope qualifiers) to disambiguate city vs metro vs admin area. Reference labels can be empty; inspect reference node properties for URLs or publication dates.

Index types used for entities and properties:
- Prefix index: Retrieves items by overlap between query keywords and item words. The query keywords can match item words exactly or as prefixes.
- Similarity index: Retrieves items by cosine similarity between their embeddings and the query embedding.

General notes across knowledge graphs:
- Use rdfs:label + FILTER(LANG(?label)="en") for labels; avoid SERVICE wikibase:label. Use wdt:Pxxx for normalized/direct values when qualifiers aren't needed. Use p:Pxxx / ps:Pxxx / pq:Pxxx to access statement qualifiers (e.g., award year via pq:P585). When dates matter, prefer xsd:dateTime and watch for year-only precision.
- Practical query patterns: use rdfs:label + FILTER(LANG(...)) for labels. Use wdt:Pxxx for direct/normalized values when qualifiers aren't needed. Use p:Pxxx / ps:Pxxx / pq:Pxxx to access qualifiers (dates via pq:P585). For dates use xsd:dateTime and expect year-only precision. For places: combine P17 with P131 or coordinate (P625) filters to avoid historical/overseas mismatches.
- Use OPTIONAL for pq: qualifiers (e.g., pq:P585), sort by qualifier (ORDER BY pq:P585 DESC) to prefer recent values. Use GROUP_CONCAT to combine multiple labels/values in one row. Watch for typed literals (xsd:dateTime, xsd:decimal) when filtering or sorting.
- Before querying, use search_entity to resolve human-friendly names to wd:Q identifiers and verify instance-of (e.g., check wdt:P31 = wd:Q5 for humans) to avoid ambiguous matches. Prefer the top match but programmatically confirm P31 before using its data.
- Use search_property to confirm property identifiers (e.g., "country" -> P17) before embedding them in queries. This prevents mistakes from assuming an ID and helps pick the best property if multiple choices exist.
- search_autocomplete can fall back to an unconstrained search or error when there are too many candidates. If this happens (e.g., "more than the maximum supported number of subject candidates"), retry with narrower constraints such as instance-of (wdt:P31), additional type filters, or short prefixes to reduce the candidate set; otherwise fallback to search_entity and verify wdt:P31.
- Use list(...) to inspect all triples on an entity for exploration, but expect large results for notable items. Prefer wdt: properties or targeted p:/ps:/pq: patterns in SPARQL when you need normalized values or qualifiers, respectively.
- Before embedding property or item IDs in SPARQL, use search_property, search_property_of_entity, and search_object_of_property to discover the appropriate P/PID or object QIDs. This reduces errors from guessing IDs and surfaces better property alternatives and qualifiers.
- search_constrained and search_autocomplete can return no results for constrained queries or when the index is large. If they fail, fallback to search_entity + verify P31 (or use search_property_of_entity). Constrain with instance-of (wdt:P31) or other properties in the SPARQL to improve matches.
- When selecting awards by year, prefer xsd:dateTime range filters (e.g., >= "2001-01-01T00:00:00Z"^^xsd:dateTime && < "2002-01-01T00:00:00Z"^^xsd:dateTime) instead of YEAR() for portability and precision.
- When selecting award winners via wdt:P166, filter ?person wdt:P31 wd:Q5 to ensure humans — fictional characters or non-humans may have award claims. If you need award years use p:P166 / ps:P166 / pq:P585 and OPTIONAL { ?stmt pq:P585 ?year } to retrieve qualifier years.
- Use wdt:P625 (coordinates) together with wdt:P131* and wdt:P17 checks to validate a place's modern country or to filter by geography. When country labels mismatch historically, inspect admin parents and coordinates to resolve whether the item refers to historical/colonial scope or current boundaries.
- Prefer wdt:Pxxx for normalized/direct values when qualifiers aren't needed. Use p:Pxxx / ps:Pxxx / pq:Pxxx to access qualifiers (e.g., pq:P585 for award year). Always fetch labels with rdfs:label + FILTER(LANG(?label) = "en").
- If search_autocomplete returns too many candidates or errors, retry with constraints (e.g., SELECT * WHERE { ?search wdt:P31 wd:Q5 }) or narrower query text. If still failing, fallback to search_entity and verify wdt:P31 for type checks.
- For award-year queries use p:P166 / ps:P166 / pq:P585 to access award statements and year qualifiers. Filter by xsd:dateTime ranges (e.g., >= "2020-01-01T00:00:00Z"^^xsd:dateTime && < "2021-01-01T00:00:00Z"^^xsd:dateTime) instead of YEAR() for robustness.
- Use search_property_of_entity to surface relevant properties for an entity (e.g., 'birth' -> P569/P19). list(...) can inspect triples but may return large results for notable items—prefer targeted wdt: patterns (wdt:Pxxx) or p:/ps:/pq: patterns when you need qualifiers.

Additional rules to follow:
- 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 ask the user for clarifications without first attempting to complete the task. If the task input is incomplete or ambiguous, try to make reasonable assumptions and document them.
- 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] Who are the current members of the Tunisian parliament (Assembly of the Representatives of the People) without an end time specified, along with their start time, electoral district, and the election in which they were elected, if available?

Step 1: find the Wikidata item for the Assembly of the Representatives of the People (Tunisian parliament). I'll search for that entity. I'll use the knowledge graph search to find the correct Q-id and verify it's the Tunisian parliament.

[Assistant]
I'll search for the relevant properties: "electoral district", "start time" and "end time" I know start/end times are likely P580/P582, but I'll still verify and find the property for "electoral district" and for "election".

[Assistant]
I'll run a SPARQL query that finds human items (?person wdt:P31 wd:Q5) with a position-held statement (p:P39 / ps:P39) equal to the Tunisian "Member of the Assembly of the Representatives of the People" (wd:Q29169698), selects only statements that do not have an end time qualifier (pq:P582), and returns the statement's start time (pq:P580), electoral district (pq:P768) and election (pq:P2715) when available. I will also retrieve English labels for persons, electoral districts and elections. Now I will execute the query.

execute

SELECT ?person ?personLabel ?start ?electoralDistrict ?electoralDistrictLabel ?election ?electionLabel WHERE {
  ?person wdt:P31 wd:Q5 .
  ?person p:P39 ?positionStmt .
  ?positionStmt ps:P39 wd:Q29169698 .
  FILTER NOT EXISTS { ?positionStmt pq:P582 ?end . }
  OPTIONAL { ?positionStmt pq:P580 ?start . }
  OPTIONAL {
    ?positionStmt pq:P768 ?electoralDistrict .
    ?electoralDistrict rdfs:label ?electoralDistrictLabel . FILTER(LANG(?electoralDistrictLabel) = "en")
  }
  OPTIONAL {
    ?positionStmt pq:P2715 ?election .
    ?election rdfs:label ?electionLabel . FILTER(LANG(?electionLabel) = "en")
  }
  ?person rdfs:label ?personLabel . FILTER(LANG(?personLabel) = "en")
}
ORDER BY ?personLabel

[Assistant]
I'll finalize with the SPARQL query I ran and summarize the results returned by that query. The summary below is based directly on the query results (no additional computation). Now I will submit the final answer.

answer

SELECT ?person ?personLabel ?start ?electoralDistrict ?electoralDistrictLabel ?election ?electionLabel WHERE {
  ?person wdt:P31 wd:Q5 .
  ?person p:P39 ?positionStmt .
  ?positionStmt ps:P39 wd:Q29169698 .
  FILTER NOT EXISTS { ?positionStmt pq:P582 ?end . }
  OPTIONAL { ?positionStmt pq:P580 ?start . }
  OPTIONAL {

Answer:
Query results (persons with position 'Member of the Assembly of the Representatives of the People' whose position statement has no end time qualifier):

1) Person: wd:Q129169085 — Anouar Marzouki
   - start time: 2023-03-13T00:00:00Z
   - electoral district: (not available)
   - election: wd:Q84037890 — 2022–23 Tunisian parliamentary election

2) Person: wd:Q129169086 — Saoussen Mabrouk
   - start time: 2023-03-13T00:00:00Z
   - electoral district: (not available)
   - election: wd:Q84037890 — 2022–23 Tunisian parliamentary election

   - electoral district: (not available)
   - election: wd:Q84037890 — 2022–23 Tunisian parliamentary election

Note: Results are taken directly from the executed SPARQL query on Wikidata. The query locates p:P39 statements with ps:P39 = wd:Q29169698 (the position "Member of the Assembly of the Representatives of the People") and filters out those statements having a pq:P582 (end time) qualifier. Electoral district (pq:P768) was not present for these statements in Wikidata; election (pq:P2715) when present is shown above.
