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 voices does seth macfarlane play on family guy?

[Tool]
Top 10 entity alternatives:
1. Family Guy, also known as I Griffin (fb:m.019nnl): Family Guy is an American adult animated sitcom created by Seth ... in 2004 for a fourth season, which began airing on May 1, 2005., TV Program

[Assistant] The Freebase ID for "Family Guy" is `fb:m.019nnl`. Now, we need to find a property that connects Seth MacFarlane to the characters he voices on Family Guy. Let's search for properties of Seth MacFarlane related to "voice" or "character".

[Tool]
Top 10 property alternatives:
1. Recordings (fb:music.artist.track): Musical Recording, Musical Artist

9. Description (fb:common.topic.description): Topic, Text
10. Date of birth (fb:people.person.date_of_birth): Date/Time, Person

No other items found

[Assistant] The property search didn't directly give us a "voice" or "character" property. Let's try searching for properties related to "character" for the entity "Family Guy".

[Tool]
Top 10 property alternatives:
1. Type (fb:type.object.type): Object, Type
2. Name (fb:type.object.name): Object, Text
3. Key (fb:type.object.key): Object, Key

9. Description (fb:common.topic.description): Topic, Text
10. Theme song (fb:tv.tv_program.theme_song): TV theme song, TV Program

No other items found

[Assistant] The property `fb:tv.tv_program.regular_cast` looks promising. It connects a TV program to its regular cast members. Let's use this property to find the cast members of Family Guy, and then filter for Seth MacFarlane.

[Tool]
Got 42 rows and 1 column, showing the first 5 and last 5 rows below:
| castmember    |
| ------------- |
| fb:m.010btxt8 |
| fb:m.02kk65p  |

| fb:m.0k6pxqf  |
| fb:m.0_m16yz  |
| fb:m.0_m17_7  |
| fb:m.0_m18dn  |

[Assistant] Now we have a list of cast members. We need to find the characters voiced by Seth MacFarlane. Let's refine the query to filter for cast members where Seth MacFarlane is the actor. We'll need to find the property that links a cast member to the actor who plays them. Let's try to find properties of `fb:m.010btxt8` (one of the cast members from the previous query) related to "actor".

[Tool]
Top 10 property alternatives:
1. Actor (fb:tv.regular_tv_appearance.actor): TV Regular Performance, TV Actor
2. Series (fb:tv.regular_tv_appearance.series): TV Regular Performance, TV Program
3. Type (fb:type.object.type): Object, Type
4. Seasons (fb:tv.regular_tv_appearance.seasons): TV Regular Performance, TV Season

6. Special performance type (fb:tv.regular_tv_appearance.special_performance_type): Special TV performance type, TV Regular Performance
7. From (fb:tv.regular_tv_appearance.from): TV Regular Performance, Date/Time

No other items found

[Assistant] The property `fb:tv.regular_tv_appearance.actor` is exactly what we need. Now we can construct the final SPARQL query.

[Tool]
Got 15 rows and 1 column, showing the first 5 and last 5 rows below:
| character                        |
| -------------------------------- |
| Stewie Griffin (fb:m.02m29p)     |
| Peter Griffin (fb:m.03n6jv)      |
| Brian Griffin (fb:m.03pcvr)      |
| Glenn Quagmire (fb:m.01sxhc)     |
| Tom Tucker (fb:m.026q0lb)        |
| ...                              |
| Kool-aid Guy (fb:m.05sr4_d)      |

| God (fb:m.02nw87f)               |
| Nate Griffin (fb:m.05srj40)      |

[Assistant] The query returns a list of characters voiced by Seth MacFarlane on Family Guy. Now we can provide the answer.

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.

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.

[Assistant] The query returns a list of events that have occurred in Hollywood, CA. To find events happening this weekend, I need to filter the events based on their start and end dates. I will search for properties related to the start and end dates of events.

[Tool]
Top 10 property alternatives:
1. Location(s) (fb:time.event.locations): Location, Event
2. Festival (fb:film.film_festival_event.festival): Film festival event, Film festival
3. Name (fb:type.object.name): Object, Text
4. Instance of recurring event (fb:time.event.instance_of_recurring_event): Recurring event, Event
5. Description (fb:common.topic.description): Topic, Text
6. Type (fb:type.object.type): Object, Type

No other items found

[Assistant] I couldn't find properties directly related to start and end dates. I will try searching for properties related to "time" or "date" for the event entity.

[Tool]
Top 10 property alternatives:
1. Location(s) (fb:time.event.locations): Location, Event
2. Description (fb:common.topic.description): Topic, Text
3. Name (fb:type.object.name): Object, Text
4. Type (fb:type.object.type): Object, Type
5. Festival (fb:film.film_festival_event.festival): Film festival event, Film festival

7. Films (fb:film.film_festival_event.films): Film festival event, Film
8. Instance of recurring event (fb:time.event.instance_of_recurring_event): Recurring event, Event
9. Notable types (fb:common.topic.notable_types): Topic, Type
10. Notable for (fb:common.topic.notable_for): notable_for, Topic

No other items found

[Assistant] Still no luck. Let's try searching for "start date" in general.

[Tool]
Top 10 property alternatives:
1. Start date (fb:medicine.medical_trial.start_date): Medical trial, Date/Time
2. Start date (fb:base.gender.personal_gender_identity.start_date): Personal gender identity, Date/Time
3. Start date (fb:fictional_universe.event_in_fiction.start_date): Fictional Date/Time, Event in fiction
4. Start Date (fb:base.iceandfire.house_lordship.start_date): House Lordship, Date/Time
5. Start Date (fb:user.pvonstackelberg.Futures_Studies.event.start_date): Date/Time, Event
6. Start Date (fb:base.popstra.lived_with.start_date): Lived With, Date/Time
7. Start date (fb:base.americancomedy.comedy_group_membership.start_date): Comedy group membership, Date/Time
8. Start date (fb:government.legislative_committee_membership.start_date): Legislative committee membership, Date/Time
9. Start Date (fb:cricket.cricket_coach_tenure.start_date): Cricket Coach Tenure, Date/Time
10. Start date (fb:user.micahsaul.advertising.ad_campaign.start_date): Ad Campaign, Date/Time

[Assistant] I see several "start date" properties. Let's try "fb:medicine.medical_trial.start_date". I will modify the query to include the start date. Since I don't know the exact dates for "this weekend", I will just retrieve the start dates for all events in Hollywood.

| 1st Annual TV Land Awards (fb:m.0z9sbfp)             |           |

[Assistant] The query returns events and their start dates, but most start dates are missing. This indicates that "fb:medicine.medical_trial.start_date" is not the correct property. I will try another "start date" property from the previous search results, "fb:fictional_universe.event_in_fiction.start_date".

[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:

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 do people speak in uk?

[Assistant]
I need to find the language spoken in the UK.
First, I will search for the UK entity.

[Tool] No entity items found

[Assistant] Okay, let's try "United Kingdom".

[User] what was franklin d roosevelt's job before president?

[Assistant] Okay, let's start by finding the entity for Franklin D. Roosevelt.

[Assistant] The first result, `fb:m.02yy8`, seems to be the correct Franklin D. Roosevelt. Now, let's find the property that represents the job or occupation before becoming president. I'll search for properties related to "predecessor" or "previous job".

[Tool]
Top 10 property alternatives:
1. Employment history (fb:people.person.employment_history): Employment tenure, Person

[Assistant] `fb:government.politician.government_positions_held` looks promising. Let's try to use it in a query.

[Tool]
Got 4 rows and 1 column:
| position     |
| ------------ |
| fb:m.03q2h_9 |
| fb:m.03q2h_j |
| fb:m.04ml2v0 |
| fb:m.0b_p9hl |

[Assistant] Okay, we have some positions. Let's get the names of these positions.

[Tool] Got no rows and 1 columns

[Assistant] The previous query didn't return any results. Let's try to find the type of the objects returned by `fb:government.politician.government_positions_held` and then query for the position held and the start date, and then order by the start date to find the previous position.

[Tool]
Got 1 row and 1 column:

| Government Position Held (fb:government.government_position_held) |

[Assistant] Okay, the type is `fb:government.government_position_held`. Now let's find the properties of this type.

[Tool]
Got 43,173 rows and 3 columns, showing the first 10 rows below:

[Assistant] Okay, let's look for properties like `start_date`, `end_date`, and `title`.

[Tool]
Top 10 property alternatives:
1. Name (fb:type.object.name): Object, Text
2. Type (fb:type.object.type): Object, Type
3. Instance (fb:type.type.instance): Object, Type

No other items found

[Assistant] That's not helpful. Let's try searching for "position start date" directly.

[Tool]
Top 10 property alternatives:
1. Start position (fb:base.nascar.nascar_race_result.start_position): NASCAR race result, Integer
2. Start date (fb:base.gender.personal_gender_identity.start_date): Personal gender identity, Date/Time
3. Start date (fb:fictional_universe.event_in_fiction.start_date): Fictional Date/Time, Event in fiction
4. Start Date (fb:base.iceandfire.house_lordship.start_date): House Lordship, Date/Time
5. Start Date (fb:user.pvonstackelberg.Futures_Studies.event.start_date): Date/Time, Event
6. Start Date (fb:base.popstra.lived_with.start_date): Lived With, Date/Time
7. Start date (fb:base.americancomedy.comedy_group_membership.start_date): Comedy group membership, Date/Time
8. Start date (fb:government.legislative_committee_membership.start_date): Legislative committee membership, Date/Time
9. Start Date (fb:cricket.cricket_coach_tenure.start_date): Cricket Coach Tenure, Date/Time
10. Start date (fb:user.micahsaul.advertising.ad_campaign.start_date): Ad Campaign, Date/Time

[Assistant] `fb:government.legislative_committee_membership.start_date` looks related to government positions, but it's not quite right. Let's try "government position start date".

[Tool]
Top 10 property alternatives:
1. Government positions (fb:government.governmental_jurisdiction.government_positions): Government Office or Title, Governmental Jurisdiction
2. Government Positions Held (fb:government.politician.government_positions_held): Government Position Held, Politician
3. Cabinet position (fb:base.obamabase.cabinet_member.cabinet_position): Cabinet position, Cabinet member
4. Cabinet position (fb:base.obamabase.possible_cabinet_member.cabinet_position): Potential cabinet member, Cabinet position

7. Offices Held (fb:royalty.chivalric_order_officer.offices_held): Chivalric Order Officer Tenure, Chivalric Order Officer
8. Governmental body (if position is part of one) (fb:government.government_position_held.governmental_body): Government Position Held, Governmental Body
9. Elected Positions Held (fb:base.government2.elected_official.elected_positions_held): Elected Government Positions Held, Elected Official
10. Officeholders (fb:government.government_office_category.officeholders): Government office category, Government Position Held

[Assistant] Still no direct "start date". Let's go back to the `fb:government.government_position_held` and list its properties again, but this time, let's look for properties related to time or date.

[Tool] Got no rows and 3 columns

[Assistant] That didn't work. Let's try listing all properties of an instance of `fb:government.government_position_held`. We can get an instance from the previous query where we found the government positions held by FDR. Let's use `fb:m.03q2h_9`.

[Tool]
Got 8 rows and 3 columns:

[Assistant] Aha! We have `fb:government.government_position_held.from` and `fb:government.government_position_held.to`. Also, `fb:government.government_position_held.office_position_or_title` gives us the title. Now we can construct a query to find the position held before the presidency.

| ----------------------------------- | --------------------- |
| Governor of New York (fb:m.02_w_r9) | 1929-01-01 (xsd:date) |

[Assistant] Okay, the query returns the Governor of New York. Let's get the label of the title.

[Tool]
Got 1 row and 2 columns:
| title_name                | from                  |

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.

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] The property "Languages spoken" (fb:location.country.languages_spoken) seems appropriate. Now I'll construct a SPARQL query to find the languages spoken in Australia.

[Tool]
Got 3 rows and 1 column:
| language                        |
| ------------------------------- |
| English Language (fb:m.02h40lc) |
| Esperanto Language (fb:m.02jcw) |
| Lojban (fb:m.04gd7)             |

[Assistant] The query returns English, Esperanto, and Lojban. While English is the primary language, Esperanto and Lojban are not. I should refine the query to only return the official language. I'll search for properties related to "official language" for the entity "Australia".

[Assistant] It seems there is no direct property for "official language". I'll stick to "Languages spoken" and filter the results to only include English.
