Explanation: The tradition of successive 'Billygoat Hennes' mascots for 1. FC Cologne is well-documented in real life, but Wikidata does not model individual goats as separate entities with start/end dates, labels, or images. The mascot is represented as a single entity (wd:Q151345) without any successor chain or time-series data. Therefore, it is impossible to retrieve the requested information via SPARQL.

[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.

[Assistant]
We see that **wd:Q151345** is the mascot character, and it has an inception date (1950), an image, and is associated with 1. FC Cologne. But we don't see direct links to individual goats.

We need to find **individual goats** that have served as "Billygoat Hennes". This likely means that each goat is a separate entity, and the mascot title is inherited — so we need to find **successors** or **instances** of the mascot.

Let’s search for properties related to "successor", "instance", or "has part" that might link to individual goats.

Question: successor

We don’t see a direct “successor” property. Let’s try searching for “instance” or “has part” to see if individual goats are listed as instances or parts.

We see that **P31 (instance of)** is the only relevant property, but that just tells us that "Billygoat Hennes" is a mascot character — not that individual goats are instances of it.

This suggests that **each individual goat is a separate entity**, and the mascot title is inherited — meaning we need to find **other entities** that are also labeled as "Billygoat Hennes" or are successors.

Let’s search for **other entities** with the name "Billygoat Hennes" or "Hennes" as a label.

Question: Hennes

Top 10 entity alternatives:

[Assistant]
We see that **wd:Q151345** is the main mascot, but we need to find **individual goats**. Let’s try searching for **"Billygoat Hennes" with a qualifier** or look for **items that are instances of "goat"** and have a connection to 1. FC Cologne.

Let’s search for **goats** that are associated with 1. FC Cologne.

No literal items found

[Assistant]
That didn’t help — “goat” is not an occupation. Let’s try searching for **goats** as entities (QIDs) and then check if any are linked to 1. FC Cologne.

Let’s search for **"goat"** as an entity:

The main entity for a goat is **wd:Q2934** (goat). Now, let’s search for **individual goats** that are **mascots of 1. FC Cologne**.

We can try searching for entities that are **instances of goat (wd:Q2934)** and have **P131 (located in administrative territorial entity)** or **P137 (owned by)** or **P161 (cast member)** linked to 1. FC Cologne.

First, let’s find the entity for **1. FC Cologne**:

Question: 1. FC Cologne

Top 10 entity alternatives:
1. 1. FC Köln (wd:Q104770, matched via 1. FC Cologne), also known as 1. FC Cologne, 1. Fußball-Club Köln 01/07 e. V., F.C. Koln, FC Koln, FCKoln, etc.: German football club based in Cologne, in North Rhine-Westphalia / is instance of association football club / is instance of soccer club

10. 1. FC Frankfurt (wd:Q286577): is instance of association football club / is instance of soccer club / association football club

[Assistant]
The entity for 1. FC Cologne is **wd:Q104770**.

Now, let’s search for **goats (wd:Q2934)** that are **associated with 1. FC Cologne** — perhaps via **P137 (owned by)** or **P161 (cast member)** or **P131 (located in)**.

Let’s try searching for entities that are **instances of goat (wd:Q2934)** and have **P137 (owned by)** = wd:Q104770.

Question: goat

No entity items found

No other items found

[Assistant]
No results. Let’s try **P161 (cast member)** — sometimes mascots are listed as cast members in media or events.

Let’s search for **goats (wd:Q2934)** that are **cast members (P161)** of something related to 1. FC Cologne.

Question: goat

No entity items found

No other items found

[Assistant]
Still no results. Let’s try a different approach: **search for any entity that has a label containing "Hennes" and is an instance of goat**.

Let’s search for entities with label "Hennes" and instance of goat:

SELECT ?search WHERE { ?search rdfs:label ?label . FILTER(CONTAINS(LCASE(?label), "hennes")) . ?search wdt:P31 wd:Q2934 }

Question: Hennes

No entity items found

No other items found

[Assistant]
No results. This suggests that **individual goats are not explicitly modeled as separate entities in Wikidata** with the property of being a goat (wd:Q2934) and being linked to 1. FC Cologne.

Let’s check if **individual Hennes goats are listed as instances of the mascot character (wd:Q151345)** — perhaps each goat is an instance of the mascot, not a goat species.

Let’s search for entities that are **instances of the mascot (wd:Q151345)**:

Question: Hennes

No entity items found

No other items found

[Assistant]
No results. This suggests that **only one entity (wd:Q151345) represents the mascot**, and **individual goats are not modeled as separate Wikidata items**.

Let’s check if there are **statements with qualifiers** on the mascot entity that indicate **successors** or **time periods**.

Let’s list all statements on wd:Q151345 again, focusing on **statements (p:)** rather than direct properties (wdt:), because successors might be stored as statements with qualifiers.

wd:Q151345

[Assistant]
This is just the normal instance-of statement. Let’s try listing **all statements** (including qualifiers) for wd:Q151345 by listing all properties with `p:` prefix:

wd:Q151345

[Assistant]
Still no successor or time-series data. Let’s check if there are any **statements with qualifiers** for **start time** or **end time**.

Let’s try to list all **statement nodes** for wd:Q151345:

wd:Q151345

[Assistant]
No statement nodes are returned — meaning **all properties are direct (wdt:) and not stored as statements with qualifiers**.

This strongly suggests that **Wikidata does not model individual goats as separate entities**. The mascot "Billygoat Hennes" is represented as a single entity (wd:Q151345), and the tradition of successive goats is **not encoded in structured data**.

### Conclusion:

After extensive exploration:
- There is **no structured data** in Wikidata representing **individual goats** as separate entities that have served as "Billygoat Hennes".
- The mascot is represented as a single entity (wd:Q151345) with inception date (1950) and image, but **no successor chain or time periods** for individual goats.
- The tradition of successive Hennes goats is **well-known in real life** (e.g., Hennes I through Hennes IX), but **not modeled in Wikidata** as structured data with start/end dates and images per goat.

Therefore, **it is not possible to construct a SPARQL query that returns the requested information** because the data does not exist in Wikidata.

We must cancel.

Explanation: The tradition of successive 'Billygoat Hennes' mascots for 1. FC Cologne is well-documented in real life, but Wikidata does not model individual goats as separate entities with start/end dates, labels, or images. The mascot is represented as a single entity (wd:Q151345) without any successor chain or time-series data. Therefore, it is impossible to retrieve the requested information via SPARQL.

SELECT ?goat ?label ?image ?start ?end WHERE { ?goat wdt:P31 wd:Q2934 . ?goat rdfs:label ?label FILTER(LANG(?label) = 'en') . OPTIONAL { ?goat wdt:P18 ?image } . # No way to link to 1. FC Cologne or get start/end times } LIMIT 10
