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 was the last time the toronto maple leafs were in the stanley cup finals?

[Assistant]
The general entity for the Stanley Cup Finals is fb:m.0cc8tt9 (Stanley Cup Finals, Sports League Championship).

Now, I need to find how to link the Toronto Maple Leafs (fb:m.0j6tr) to their participation in the Stanley Cup Finals (fb:m.0cc8tt9), and extract the year or date of their most recent appearance.

I'll look for properties related to "participation", "finals", or "Stanley Cup" for the Toronto Maple Leafs entity.

The property "Championships" (fb:sports.sports_team.championships) links a sports team to championship events they've participated in or won. Since the Stanley Cup Finals is a championship event, this property is likely to be relevant.

Next, I'll list the values of the "Championships" property for the Toronto Maple Leafs (fb:m.0j6tr) to see which events are linked and if they include Stanley Cup Finals appearances, along with their dates.

[Assistant]
The Toronto Maple Leafs are linked to several Stanley Cup Finals events, each with a specific year in the event name (e.g., "1967 Stanley Cup Finals"). To answer the question, I need to determine the latest (most recent) year among these events.

To do this programmatically, I will:
- Retrieve the labels (names) of these championship events.
- Extract the year from the event name.
- Select the event with the latest year.

I'll write a SPARQL query that gets all championship events for the Toronto Maple Leafs, retrieves their labels, extracts the year, and returns the latest one.

Feedback (status=done):
The SPARQL query correctly retrieves the last Stanley Cup Finals appearance for the Toronto Maple Leafs by selecting their championship events, extracting the year from the label, and ordering by year descending with a limit of 1. The answer (1967) is accurate, and the query returns the IRI of the event as required. No further improvements are necessary.

Troy Aikman played for the Dallas Cowboys (fb:m.02896) from 1989 to 2000 as a quarterback.

To provide a more complete answer, I should also check if there are properties for college or university teams, since "where did ... play football" could also refer to his college football career. I will search for properties related to "college" for Troy Aikman.

Feedback (status=refine):
The SPARQL query is generally correct in structure and retrieves the relevant teams and colleges where Troy Aikman played football. However, there are a few issues to refine:

1. The query retrieves multiple rows due to the combination of all possible team and college label language variants, leading to a large number of redundant rows. To improve, you should filter the labels to English (e.g., FILTER (lang(?teamLabel) = 'en') and FILTER (lang(?collegeLabel) = 'en')) or only select the IRIs if labels are not explicitly requested.
2. The answer summary is correct, but the query could be simplified to avoid the Cartesian product between teams and colleges, which is not necessary for this question.
3. The query currently returns both IRIs and labels, which is fine, but the labels should be optional and filtered for English if included.

Refine the query to address these points for a more concise and relevant result.

[Assistant]
Thank you for the feedback. Here’s my plan to refine the query:

1. I will filter the labels to English using FILTER (lang(?teamLabel) = 'en') and FILTER (lang(?collegeLabel) = 'en').
2. To avoid the Cartesian product between teams and colleges, I will use two separate OPTIONAL blocks and use UNION to keep the results concise—one for professional teams, one for colleges.
3. I will keep the IRIs in the result and make the English labels optional.

Let me construct the improved query.

The SPARQL query correctly retrieves all institutions where Troy Aikman played football, including both his college teams and his NFL team. The query returns the IRIs of the institutions as required, and the answer matches the expected entities (Dallas Cowboys, University of Oklahoma, UCLA). The use of OPTIONAL for labels is appropriate. No further refinement is necessary.

[User] what type of government was formed when italy unified?

[Assistant]
Let's break down the question:

1. The question is about the type of government formed when Italy unified.
2. We need to identify the entity for "Italy" and the event of "Italian unification" (likely "Risorgimento" or "Unification of Italy").
3. We then need to find the government type established at that time.

Step 1: Search for "Italian unification" in Freebase to find the relevant entity.

10. Unification (fb:m.0f6v3): Unification, in computer science and logic, is an algorithmic pr...covering all its solutions, and containing no redundant members.

[Assistant]
The most relevant entity for "Italian unification" is "Italian unification, also known as Il Risorgimento, The Resurgence" (fb:m.0g7fg), which is described as the political and social movement that unified Italy.

Next, I need to determine the type of government that was formed as a result of this event. This likely involves finding the government established in Italy after the unification event.

I will now search for properties related to "government" for the entity "Italy" to see if there is a property indicating the type of government at the time of unification.

The most relevant property is "Form of Government" (fb:location.country.form_of_government), which links a country to its type of government.

However, since the form of government can change over time, and the question is specifically about the government formed at unification, I need to check if there is a way to get the form of government for Italy at the time of unification, or if there is a historical government entity linked to the unification event.

I will now check what objects are linked to Italy via the "Form of Government" property to see if there are historical forms listed.

Italy is linked to three forms of government in Freebase:
- Unitary state (fb:m.01fpfn)
- Parliamentary republic (fb:m.0glnsx)
- Constitutional republic (fb:m.0c9rw5)

However, these forms reflect modern Italy. At the time of unification (1861), Italy was initially a constitutional monarchy under the House of Savoy (Kingdom of Italy). I need to check if Freebase records this historical government form.

I will search for "Kingdom of Italy" in Freebase to see if it is represented as a historical government entity.

The most relevant entity for the government formed at Italian unification is "Kingdom of Italy" (fb:m.02psqkz), described as a state founded in 1861 when King Victor Emmanuel II of Sardinia was proclaimed King of Italy.

Now, I will check the form of government for the "Kingdom of Italy" (fb:m.02psqkz) to see how Freebase classifies it.

The SPARQL query correctly retrieves the forms of government for the Kingdom of Italy (fb:m.02psqkz) from Freebase, returning the IRIs of the government types as required. The answer accurately reflects the historical context of Italian unification in 1861 and lists all relevant government types found in the query result. No further refinement is necessary.

After a step-by-step investigation:

1. I identified the correct Freebase entities for Ike Turner (fb:m.0dbzg) and Tina Turner (fb:m.01vwyqp).
2. I found their children in Freebase:
   - Ronnie Turner (fb:m.0ggl36p)
   - Raymond Craig Turner (fb:m.0j5dh53)
   - Ike Turner Jr (fb:m.0j5dj1w)

   - Twanna Turner Melby (fb:m.0p18qj6)
   (Note: Only Ronnie and Raymond Craig are listed as Tina's children.)
3. I attempted to find properties related to "place of residence" or "location" for these children, but Freebase does not appear to have this information for any of them. The closest available properties are "country of nationality" and "place of birth," but not current residence.

Therefore, based on the available data in Freebase, there is no information about the current locations or residences of Ike and Tina Turner's children.

Final SPARQL query (for completeness, showing the children IRIs):

```sparql
SELECT ?child WHERE {
  VALUES ?parent { fb:m.0dbzg fb:m.01vwyqp }
  ?parent fb:people.person.children ?child .
}
```

Answer: Freebase does not contain information about the current locations or residences of Ike and Tina Turner's children.

[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/

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] where are ike and tina turner's children?

[Assistant]
Let's break down the question:

1. The user is asking about the children of Ike and Tina Turner, specifically their current locations ("where are ... children?").
2. I need to identify the entities for Ike Turner and Tina Turner.
3. Then, I need to find their children.
4. Finally, I need to find the current locations (possibly place of residence or similar) of those children.

Let's start by searching for the entities "Ike Turner" and "Tina Turner" in Freebase.

Feedback (status=done):
The answer is correct and complete given the limitations of the Freebase knowledge graph. The system correctly identified the children of Ike and Tina Turner and attempted to find their current locations or residences, but noted that such information is not available in Freebase. The SPARQL query returns the IRIs of the children, as required. No further refinement is necessary.
