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 kind of products does nike sell?

[Assistant]
To answer this question, I need to:

1. Identify the entity for "Nike" in Freebase.
2. Find properties related to products sold by Nike.
3. Retrieve the types or categories of products associated with Nike.

Let's start by searching for the entity "Nike" in Freebase.

[Assistant]
The correct entity for Nike, the company, is fb:m.0lwkh (Nike, Inc.).

Next, I need to find properties related to the products that Nike sells. I will search for properties of this entity related to "product".

[Assistant]
The most relevant properties are:
- Products (fb:business.consumer_company.products)
- Product lines (fb:business.consumer_company.product_lines)
- Brands (fb:business.consumer_company.brands)

To answer "what kind of products does Nike sell?", I should focus on the "Products" and "Product lines" properties. I will start by listing the products associated with Nike, Inc. using the "Products" property.

[Tool]
Got 5 rows and 3 columns:
| subject                 | property                                         | object       |

| Nike, Inc. (fb:m.0lwkh) | Products (fb:business.consumer_company.products) | fb:m.0zgt159 |

[Assistant]
I found five product entities associated with Nike, Inc. To determine what kind of products these are, I need to retrieve their types or categories. I will get the types and labels for these product entities.

Let's write a SPARQL query to retrieve the types and labels for these products.

[Tool]
SPARQL execution failed:
Tried to allocate 3.3 GB, but only 1.8 GB were available. Clear the cache or allow more memory for QLever during startup

[Assistant]
The previous query failed due to memory limitations. To avoid this, I will simplify the query by first retrieving just the labels for the product entities. This will help us identify what kind of products they are, and then I can further refine the query if needed.

Let's get the labels for the five product entities.

[Tool]
Got 5 rows and 2 columns:
| product      | productLabel |
| ------------ | ------------ |
| fb:m.062z3yz |              |
| fb:m.0cr0ggp |              |
| fb:m.0cr0h2l |              |
| fb:m.0rz1q7s |              |
| fb:m.0zgt159 |              |

[Assistant]
The product entities associated with Nike, Inc. do not have labels in the data returned, which means we cannot directly identify the product types from these specific entities.

As an alternative, I will now check the "Product lines" property for Nike, Inc. to see if it provides more descriptive or categorized information about the types of products Nike sells.

[Tool]
Got 3 rows and 3 columns:
| subject                 | property                                                   | object        |

| Nike, Inc. (fb:m.0lwkh) | Product lines (fb:business.consumer_company.product_lines) | fb:m.0cr0k6p  |

[Assistant] I found three product line entities associated with Nike, Inc. To determine what kind of products these are, I will retrieve their labels. This may give us more insight into the types of products Nike sells.

[Tool]
Got 3 rows and 2 columns:
| productLine   | productLineLabel |
| ------------- | ---------------- |
| fb:m.0103fvht |                  |
| fb:m.0cr0ctt  |                  |
| fb:m.0cr0k6p  |                  |

[Assistant]
The product line entities also do not have labels in the data returned, so we are not getting human-readable information about the types of products Nike sells from these properties.

As another approach, I will check the "Brands" property for Nike, Inc., as sometimes brands are named after product categories (e.g., "Nike Golf", "Nike Basketball"). This might give us more information about the types of products Nike is associated with.

[Tool]
Got 3 rows and 3 columns:
| subject                 | property                                     | object       |
| ----------------------- | -------------------------------------------- | ------------ |
| Nike, Inc. (fb:m.0lwkh) | Brands (fb:business.consumer_company.brands) | fb:m.0cr0gxk |
| Nike, Inc. (fb:m.0lwkh) | Brands (fb:business.consumer_company.brands) | fb:m.0gl_dcq |
| Nike, Inc. (fb:m.0lwkh) | Brands (fb:business.consumer_company.brands) | fb:m.0_xgpqn |

[Assistant] I found three brand entities associated with Nike, Inc. I will now retrieve the labels for these brands to see if they provide insight into the types of products Nike sells.

[Tool]
Got 3 rows and 2 columns:
| brand        | brandLabel |
| ------------ | ---------- |
| fb:m.0cr0gxk |            |
| fb:m.0gl_dcq |            |
| fb:m.0_xgpqn |            |

[Assistant]
The brand entities associated with Nike, Inc. also do not have labels in the data returned, so we are not getting human-readable information from these properties either.

Given that the direct product, product line, and brand properties do not yield descriptive labels, I will try a broader approach: searching for properties of Nike, Inc. related to "category" or "type" to see if there is a more general property indicating the kinds of products Nike sells.

[Assistant]
The English description for Nike, Inc. is truncated in the result, but based on the typical content of such descriptions and the multilingual versions, it is clear that Nike is known for selling products such as sportswear, footwear, and sports equipment.

To provide a SPARQL query that answers "what kind of products does Nike sell?" as directly as possible from the Freebase data, I will return the product entities linked to Nike, Inc. via the "products" property, along with any available labels or types. Since the labels are missing, the query will at least show the identifiers, which are the best available structured answer from Freebase.

[User] who plays roxanne in ghost rider?

[Assistant]
Let's break down the question:

1. The user wants to know who plays the character "Roxanne" in the movie "Ghost Rider".
2. We need to identify:
   - The entity for the movie "Ghost Rider".
   - The character "Roxanne" in that movie.
   - The actor who played that character.

First, I'll search for the entity "Ghost Rider" in Freebase.

[Assistant] The property fb:film.film.starring ("Performances") is likely to link the film to its cast and their roles. I will now list some triples where "Ghost Rider" (fb:m.06yykb) is the subject and fb:film.film.starring is the property, to see the structure of the cast information and find the character "Roxanne".

[Assistant]
The "Performances" property links the film to several entities (likely film performance nodes). Each of these nodes probably contains information about the actor and the character they played.

Next, I will check the properties of one of these performance nodes (e.g., fb:m.03jrkkx) to see how the actor and character are represented.

The relevant properties for a film performance are:
- fb:film.performance.character (Character)
- fb:film.performance.actor (Actor)

I will now list the values for these properties for all the performance nodes linked to "Ghost Rider" to find which one corresponds to "Roxanne" and who played her.

[Assistant]
From the data:
- Eva Mendes (fb:m.03_x5t) played Roxanne Simpson (fb:m.02ph41w) in "Ghost Rider" (fb:m.06yykb).
- Raquel Alessi (fb:m.026ths5) played "Young Roxanne Simpson" in the same film.

The main answer is Eva Mendes, as she played the adult Roxanne Simpson.

Now, I will write a SPARQL query that returns the actor(s) who played Roxanne Simpson in "Ghost Rider", including their IRIs and optionally their names.

[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 http://galera:7002

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 team is hank baskett on 2010?

[Assistant]
Let's break down the question:

1. The user is asking about the team that Hank Baskett was on in 2010.
2. First, I need to identify the entity for "Hank Baskett" in Freebase.
3. Then, I need to find the property that links a person (specifically an athlete) to a sports team, ideally with a time qualifier or a way to filter for the year 2010.

Step 1: Search for the entity "Hank Baskett" in Freebase.

The top result for "Hank Baskett" is fb:m.0d81yf, who is described as an American football player. This matches the context of the question.

Next, I need to find the property that links an American football player to the team(s) they played for, ideally with a way to filter for the year 2010.

I'll search for properties related to "team" for the entity fb:m.0d81yf.

[Assistant]
The most relevant property is "Teams" (fb:sports.pro_athlete.teams), which links an athlete to the sports teams they've played for. This property likely contains information about the teams and possibly the time periods.

Next, I need to check the structure of the values for fb:sports.pro_athlete.teams to see if there is a way to filter for the year 2010. I'll list some triples where Hank Baskett (fb:m.0d81yf) is the subject and fb:sports.pro_athlete.teams is the property.

[Assistant]
Hank Baskett is linked to five teams via the fb:sports.pro_athlete.teams property. The objects (team roster entries) are:

- fb:m.01205rsm
- fb:m.064w5kf
- fb:m.0h_1w26
- fb:m.0hpxtbg
- fb:m.0hpxtbr

These are likely "Sports team roster" nodes, which should contain information about the team and the time period the athlete was on the team.

Next, I need to check what properties are available for one of these roster entries (e.g., fb:m.01205rsm) to find the actual team and the time period.

[Assistant]
The roster entry fb:m.01205rsm links Hank Baskett to the Minnesota Vikings (fb:m.051q5) from 2010-09-22 to 2011. This means he was on the Minnesota Vikings during part of 2010.

To be thorough, I should check the other roster entries to see if he was on any other teams in 2010, as players can switch teams within a year. I'll check the "from" and "to" properties for the other roster entries.

- Philadelphia Eagles: from 2010-03-12 to 2010-09-21
- Minnesota Vikings: from 2010-09-22 onward

Therefore, in 2010, Hank Baskett played for three teams: Indianapolis Colts, Philadelphia Eagles, and Minnesota Vikings.

Now, I will construct a SPARQL query that returns the IRIs of the teams Hank Baskett was on in 2010, along with optional labels.

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:

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.

The two most relevant properties are:
- "Languages spoken" (fb:location.country.languages_spoken)
- "Official Language" (fb:location.country.official_language)

Since the user asked generally about "what language do they speak in Malta," I will use "Languages spoken" to cover all spoken languages, not just the official ones.

Now, I will construct a SPARQL query to retrieve the languages spoken in Malta (fb:m.04v3q) using the property fb:location.country.languages_spoken. I will also try to get the labels of the languages for better readability.

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:

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.

[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 http://galera:7002

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#

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] when does the vietnam war end?

[Assistant]
Let's break down the question:

1. We need to identify the entity "Vietnam War" in Freebase.
2. We need to find the property that represents the end date or end time of an event or war.
3. We will then construct a SPARQL query to retrieve the end date of the Vietnam War.

First, I'll search for the "Vietnam War" entity in Freebase.

[Tool]
Top 10 entity alternatives:
1. Vietnam War, also known as American War, Vietnam Conflict, Second Indochina War (fb:m.07_nf): The Vietnam War, also known as the Second Indochina War, and als... operations, involving ground forces, artillery, and airstrikes., has type Military Conflict
2. Vietnam War (fb:m.05hr0qy): Welcome to Vietnam War, a shared, online source of facts and inf...d the world. Join us and be a part of building and improving it!
3. Vietnam War (fb:m.04w9w7g): has type Book
4. Vietnam War (fb:m.0126yztd): has type Musical Recording
5. Vietnam War (fb:m.0j1g15s): has type Book
6. Vietnam War (fb:m.0126tn27)
7. Vietnam War (fb:m.0bkmwwm)
8. Vietnam War (fb:m.07q10j8)
9. Vietnam War, 1961-1975--Campaigns (fb:m.0bnv2t2)
10. War in Vietnam (fb:m.0bwhf7n): The War in Vietnam, codenamed Operation Masterdom by the British... that grew out of the British occupation of Saigon from 1945–46., has type Military Conflict

[Assistant]
The most relevant entity for the Vietnam War as a historical military conflict is fb:m.07_nf.

Next, I need to find the property in Freebase that represents the "end date" or "end time" of an event, specifically for military conflicts.

I'll search for properties related to "end date".

[Tool]
Top 10 property alternatives:
1. End date (fb:fictional_universe.event_in_fiction.end_date): links to type Fictional Date/Time, part of Event in fiction schema
2. End Date (fb:user.pvonstackelberg.Futures_Studies.event.end_date): links to type Date/Time, part of Event schema
3. End Date (fb:base.popstra.lived_with.end_date): part of Lived With schema, links to type Date/Time
4. End Date (fb:base.iceandfire.house_lordship.end_date): part of House Lordship schema, links to type Date/Time
5. End Date (fb:base.formula1.formula_1_season.end_date): part of Formula 1 Season schema, links to type Date/Time
6. End date (fb:government.legislative_committee_membership.end_date): part of Legislative committee membership schema, links to type Date/Time
7. End date (fb:opera.opera_production_venue_relationship.end_date): part of Opera production venue relationship schema, links to type Date/Time
8. End Date (fb:cricket.cricket_coach_tenure.end_date): part of Cricket Coach Tenure schema, links to type Date/Time
9. End date (fb:user.micahsaul.advertising.ad_campaign.end_date): part of Ad Campaign schema, links to type Date/Time
10. End date (fb:celebrities.romantic_relationship.end_date): part of Romantic relationship schema, links to type Date/Time

[Assistant]
Most of the "end date" properties found are schema-specific and not directly related to military conflicts or general events. The most general one seems to be:

- End Date (fb:user.pvonstackelberg.Futures_Studies.event.end_date): links to type Date/Time, part of Event schema

However, to ensure accuracy, I'll also search for properties related to "military conflict end date" or "date" for the Vietnam War entity itself, to see if there is a more specific property used for wars.

I'll search for properties of the Vietnam War entity related to "date".

No other items found

[Assistant]
The property fb:time.event.end_date is the most appropriate for retrieving the end date of the Vietnam War, as it is part of the general Event schema.

Now, I'll construct a SPARQL query to get the end date of the Vietnam War (fb:m.07_nf) using the property fb:time.event.end_date. I'll also optionally retrieve the label for clarity.

[Tool]
Failed to call function execute:
failed to parse input: parse error at position 18 for token OPTIONAL with content 'OPTIONAL' (the input most likely does not follow the grammar)

[Assistant]
It looks like there was a syntax error in my previous query due to the placement of the OPTIONAL clause. In SPARQL, OPTIONAL clauses should be inside the WHERE block, and the SELECT clause should only include variables.

I'll correct the query to properly structure the OPTIONAL clause and try again.
