Wayne Gretzky's first team, according to the available Freebase data, was the Edmonton Oilers (fb:m.0jnmj), starting in 1979.

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

You have access to the following knowledge graphs:
freebase at https://qlever.cs.uni-freiburg.de/api/freebase

You can use the following SPARQL prefixes implicitly in all functions:
fb: <http://rdf.freebase.com/ns/
fbkey: <http://rdf.freebase.com/key/
rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#
rdfs: <http://www.w3.org/2000/01/rdf-schema#
owl: <http://www.w3.org/2002/07/owl#
xsd: <http://www.w3.org/2001/XMLSchema#
foaf: <http://xmlns.com/foaf/0.1/
skos: <http://www.w3.org/2004/02/skos/core#
dct: <http://purl.org/dc/terms/
dc: <http://purl.org/dc/elements/1.1/
prov: <http://www.w3.org/ns/prov#
schema: <http://schema.org/
geo: <http://www.opengis.net/ont/geosparql#
geosparql: <http://www.opengis.net/ont/geosparql#

hint: <http://www.bigdata.com/queryHints#
wikibase: <http://wikiba.se/ontology#
qb: <http://purl.org/linked-data/cube#
void: <http://rdfs.org/ns/void#

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] what was wayne gretzky's first team?

[Assistant] Let's start by looking at some similar examples.

[Tool]
Example 1:
Question:
what teams did gretzky play on?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.0839s ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.0839s fb:sports.pro_athlete.teams ?y .
  ?y fb:sports.sports_team_roster.team ?x .
}

Using entities:
Wayne Gretzky, also known as The Great One, Wayne Douglas Gretzky, The White Tornado, Wayne Douglas Gretzky, CC, Wayne Gretsky (fb:m.0839s): Wayne Douglas Gretzky, CC is a Canadian former professional ice ..., Gretzky's intelligence and reading of the game were unrivaled., has type Ice hockey coach

Using properties:
Teams (fb:sports.pro_athlete.teams): links to type Sports team roster, part of Athlete schema
Team (fb:sports.sports_team_roster.team): part of Sports team roster schema, links to type Sports Team

Example 2:
Question:
what 4 teams did wayne gretzky play for?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.0839s ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.0839s fb:sports.pro_athlete.teams ?y .
  ?y fb:sports.sports_team_roster.team ?x .
}

Using entities:
Wayne Gretzky, also known as The Great One, Wayne Douglas Gretzky, The White Tornado, Wayne Douglas Gretzky, CC, Wayne Gretsky (fb:m.0839s): Wayne Douglas Gretzky, CC is a Canadian former professional ice ..., Gretzky's intelligence and reading of the game were unrivaled., has type Ice hockey coach

Using properties:
Teams (fb:sports.pro_athlete.teams): links to type Sports team roster, part of Athlete schema
Team (fb:sports.sports_team_roster.team): part of Sports team roster schema, links to type Sports Team

Example 3:
Question:
who did wayne gretzky play 4?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.0839s ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.0839s fb:sports.pro_athlete.teams ?y .
  ?y fb:sports.sports_team_roster.team ?x .
}

Using entities:
Wayne Gretzky, also known as The Great One, Wayne Douglas Gretzky, The White Tornado, Wayne Douglas Gretzky, CC, Wayne Gretsky (fb:m.0839s): Wayne Douglas Gretzky, CC is a Canadian former professional ice ..., Gretzky's intelligence and reading of the game were unrivaled., has type Ice hockey coach

Using properties:
Teams (fb:sports.pro_athlete.teams): links to type Sports team roster, part of Athlete schema
Team (fb:sports.sports_team_roster.team): part of Sports team roster schema, links to type Sports Team

[Assistant]
The similar examples show how to get all teams Wayne Gretzky played for, using the entity fb:m.0839s (Wayne Gretzky) and the properties fb:sports.pro_athlete.teams and fb:sports.sports_team_roster.team.

However, the user wants to know his "first" team. To determine this, we need to see if there is a property for the start date or order of his team memberships.

I'll inspect the properties of the sports team roster object (?y) to see if there is a start date or similar property.

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

You have access to the following knowledge graphs:
freebase at https://qlever.cs.uni-freiburg.de/api/freebase

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

void: <http://rdfs.org/ns/void#

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] what languages are there in japan?

[Assistant] Let's start by looking at some similar examples.

[Tool]
Example 1:
Question:
where do most of the people live in japan?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.03_3d ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.03_3d fb:location.location.contains ?x .
  ?x fb:topic_server.population_number ?sk0 .
}
ORDER BY DESC ( xsd:float ( ?sk0 ) )
LIMIT 1

Using entities:
Japan, also known as Япония, State of Japan, JAP, NTSC J, Nippon-koku (fb:m.03_3d): Japan is an island country in East Asia. Located in the Pacific ...on of Japan is in Chinese history texts from the 1st century AD., has type Country

Using properties:
Contains (fb:location.location.contains): part of Location schema, links to type Location

Example 2:
Question:
what countries does japan export to?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.03_3d ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.03_3d fb:location.statistical_region.places_exported_to ?y .
  ?y fb:location.imports_and_exports.exported_to ?x .
}

Using entities:
Japan, also known as Япония, State of Japan, JAP, NTSC J, Nippon-koku (fb:m.03_3d): Japan is an island country in East Asia. Located in the Pacific ...on of Japan is in Chinese history texts from the 1st century AD., has type Country

Using properties:
Exported to (fb:location.imports_and_exports.exported_to): part of Imports and exports schema, links to type Statistical region
Places exported to (fb:location.statistical_region.places_exported_to): links to type Imports and exports, part of Statistical region schema

Example 3:
Question:
what is the language used in indonesia?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.03ryn ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.03ryn fb:location.country.official_language ?x .
}

Using entities:
Indonesia, also known as Republic of Indonesia, The Republic of Indonesia (fb:m.03ryn): Indonesia, officially the Republic of Indonesia, is a sovereign ... early centuries CE, and Hindu and Buddhist kingdoms flourished., has type Country

Using properties:
Official Language (fb:location.country.official_language): links to type Human Language, part of Country schema

[Assistant]
From the similar examples, especially the third one ("what is the language used in indonesia?"), I see that the property fb:location.country.official_language is used to get the official languages of a country, and the entity for Japan is fb:m.03_3d.

However, the user asked for "what languages are there in Japan?", which could mean both official and other languages spoken in Japan. To be thorough, I should check if there is a property for "languages spoken" or "languages used" in addition to "official language".

First, I'll search for properties related to "language" for the Japan entity.

[Tool]
Top 10 property alternatives:
1. Languages spoken (fb:location.country.languages_spoken): links to type Human Language, part of Country schema
2. Type (fb:base.biblioness.bibs_location.loc_type): part of Bibs Location schema, links to type Text
3. Type (fb:type.object.type): part of Object schema, links to type Type
4. Pronunciation (fb:base.schemastaging.context_name.pronunciation): links to type Pronunciation, part of Context name schema
5. Titles (fb:media_common.netflix_genre.titles): part of Netflix Genre schema, links to type Netflix Title
6. Adjectival form (fb:location.location.adjectival_form): part of Location schema, links to type Text
7. Adjectival form (fb:freebase.linguistic_hint.adjectival_form): part of Linguistic hint schema, links to type Text
8. Adjectival form (fb:base.aareas.schema.administrative_area.adjectival_form): part of Administrative Area schema, links to type Text
9. Flag (fb:symbols.flag_referent.flag): part of Flag referent schema, links to type Flag use
10. Continent (fb:base.locations.countries.continent): links to type Continents, part of Countries schema

No other items found

[Assistant]
The property fb:location.country.languages_spoken ("Languages spoken") seems to be the most appropriate for finding all languages spoken in Japan, not just the official ones.

I will now write a SPARQL query to retrieve all languages spoken in Japan (fb:m.03_3d) using this property, and also try to get their labels for readability.

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.

[Assistant]
From the similar examples, I see that:

- The Miami Dolphins entity is fb:m.04vn5.
- To get players on a team, the property fb:sports.sports_team.roster is used, which links to a roster node.
- The roster node has properties like fb:sports.sports_team_roster.player (the player), fb:sports.sports_team_roster.position (the position), and possibly fb:sports.sports_team_roster.jersey_number (the jersey number).

My next step is to verify the property for jersey number and check how it is used in the Freebase schema.

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] in which continent is germany?

[Assistant] Let's start by looking at some similar examples.

[Tool]
Example 1:
Question:
what countries in the world speak german?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.04306rv ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.04306rv fb:language.human_language.countries_spoken_in ?x .
}

Using entities:
German Language, also known as Hochdeutsch, Tedesco, High German, German, Standard Language, German, Standard (fb:m.04306rv): German is a West Germanic language that derives most of its voca...alects or dialect groups are sometimes referred to as languages., has type Human Language

Using properties:
Spoken in countries (fb:language.human_language.countries_spoken_in): part of Human Language schema, links to type Country

Example 2:
Question:
what continent is australia in?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.0chghy ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.0chghy fb:location.location.containedby ?x .
  ?x fb:common.topic.notable_types fb:m.01mh .
}

Using entities:
Continent (fb:m.01mh): A continent is a large land mass, defined mostly by conventional...but closely related to tectonic plates within the earth's crust.
Australia, also known as Commonwealth of Australia, The Commonwealth of Australia (fb:m.0chghy): Australia, officially the Commonwealth of Australia, is an Ocean...e six colonies federated, forming the Commonwealth of Australia., has type Country

Example 3:
Question:
in which continent is russia?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.06bnz ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.06bnz fb:base.locations.countries.continent ?x .
}

Using entities:
Russia, also known as Russian Federation, Россия (fb:m.06bnz): Russia, also officially known as the Russian Federation, is a co...descendants, the medieval state of Rus arose in the 9th century., has type Country

Using properties:
Continent (fb:base.locations.countries.continent): links to type Continents, part of Countries schema

[Assistant]
From the similar examples, I see that:

- The entity for Germany is likely needed.
- The property fb:base.locations.countries.continent is used to link a country to its continent.
- The result should be the continent entity.

Next, I will search for the entity for Germany in Freebase.

[Tool]
Top 10 entity alternatives:
1. Germany, also known as Deutschland, Federal Republic of Germany, Bundesrepublik Deutschland, BRD (fb:m.0345h): Germany, officially the Federal Republic of Germany, is a federa...9, the Empire was replaced by the parliamentary Weimar Republic., has type Country
2. Germany Germany, also known as Germany, Germany (fb:m.0fsdfvd): has type Musical Artist
3. Germany (fb:m.0fqgj3): The Germany Pavilion is part of the World Showcase within Epcot ... Florida. Its location is between the China and Italy pavilions., has type Building
4. Looking for Nicolas Sarkozy, also known as Germany (fb:m.0hr9606): Looking for Nicolas Sarkozy is a 2011 French documentary film di...France. It was released on TV network Arte on December 21, 2011., has type Film
5. The Cambridge illustrated history of Germany, also known as Germany (fb:m.0b3z6xw): has type Book Edition
6. Germany (fb:m.01vhjk6): has type Musical Artist
7. Germany (fb:m.03cl0jw): In European elections, Germany is a constituency of the European...y-six members, the most of any European Parliament constituency., has type Political District

9. Germany (fb:m.09z3q01): has type Book Edition
10. Germany (fb:m.0c5s7wz): has type Book Edition

[Assistant]
The correct entity for Germany as a country is fb:m.0345h.

Based on the similar example for Russia, I will use the property fb:base.locations.countries.continent to find the continent for Germany.

Now, I will construct the SPARQL query to get the continent of Germany.

[User] what year did baltimore ravens win super bowl?

[Assistant] Let's start by looking at some similar examples.

Question:
what year did baltimore ravens win the superbowl?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.01ct6 ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.01ct6 fb:sports.sports_team.championships ?x .
  ?x fb:sports.sports_championship_event.championship fb:m.06x5s .
}

Using entities:

Example 3:
Question:

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.05tfm ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.05tfm fb:sports.sports_team.championships ?x .

Using properties:
Championships (fb:sports.sports_team.championships): links to type Sports League Championship Event, part of Sports Team schema

[Assistant]
The similar examples show that to find the years the Baltimore Ravens won the Super Bowl, we need to:

1. Get the entity for the Baltimore Ravens (fb:m.01ct6).
2. Use the property fb:sports.sports_team.championships to get their championship events.
3. Filter for events that are Super Bowls (fb:m.06x5s).
4. Retrieve the year of those championship events.

The examples do not show how to get the year, so I need to check what properties are available for the championship event entity, especially those related to date or year. I'll list properties for a championship event to find the correct one for the year.
