[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#

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.

[Assistant] The episode "Kiss and Tell" (fb:m.05dh_mz) is part of the TV series "Young Americans" (fb:m.04qryp). I will now check if Geoffrey Kirkland production designed this TV series or any related entity. I will check properties of the TV series fb:m.04qryp to find production designer information.

[Tool]
Top 10 property alternatives:
1. Currently in production (fb:tv.tv_program.currently_in_production): part of TV Program schema, links to type Boolean
2. Program creator (fb:tv.tv_program.program_creator): links to type TV Program Creator, part of TV Program schema
3. Genre (fb:tv.tv_program.genre): part of TV Program schema, links to type TV Genre
4. Country of origin (fb:tv.tv_program.country_of_origin): part of TV Program schema, links to type Country

No other items found

[Assistant] There is no direct property related to production designer for the TV series "Young Americans" (fb:m.04qryp). Given the data available, it seems there is no direct link between Geoffrey Kirkland as a production designer and any work involving Charlie Hunnam in the knowledge graph. I will now finalize the answer stating that there is no such work found in the knowledge graph.

[Tool] Stopped generation process

[User]
Feedback (status=done):
The SPARQL query correctly attempts to find films where Charlie Hunnam acted and Geoffrey Kirkland was the production designer by linking the film to both entities using appropriate properties. The query returns no results, which aligns with the answer that no such work exists in the knowledge graph. The query also optionally retrieves English labels for better readability. Overall, the output is correct and complete given the data available.

[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 colleges and universities did President Kennedy attend?

[User]
Feedback (status=refine):
The SPARQL query correctly retrieves all educational institutions associated with John F. Kennedy, including primary, secondary, and higher education institutions. However, the user question specifically asks for colleges and universities, which typically refer to higher education institutions. The current answer includes schools that are not colleges or universities (e.g., Dexter School, Canterbury School, Choate Rosemary Hall). To improve, the query should be refined to filter out non-college/university institutions, possibly by restricting to entities of type 'college' or 'university' or by excluding known primary/secondary schools. This will make the answer more precise and relevant to the user's question.

[Assistant] The feedback indicates that the current query returns all educational institutions including primary and secondary schools, but the user specifically asked for colleges and universities. To refine the query, I will filter the institutions to only include those that are of type college or university. I will check the types of the institutions and then restrict the query to those with types related to college or university.

[Assistant]
For Harvard University (fb:m.03ksy), there is a property fb:common.topic.notable_types with the object College/University (fb:m.01y2hnl). This suggests that the property fb:common.topic.notable_types can be used to filter institutions that are colleges or universities.

I will now refine the query to only include institutions that have the notable type College/University (fb:m.01y2hnl).

Feedback (status=refine):
The answer states that John F. Kennedy attended Harvard College and Harvard University, but the SPARQL query result also includes Stanford Graduate School of Business and Princeton University, which are not correct for JFK. The query should be refined to exclude institutions that JFK did not attend. Additionally, Harvard College and Harvard University are closely related (Harvard College is the undergraduate school of Harvard University), so it might be sufficient to mention just Harvard University or clarify the distinction. The query should be improved to accurately reflect JFK's actual educational institutions, which are Harvard University (Harvard College) and not Stanford or Princeton.

[Assistant] The feedback points out that the current query includes institutions like Stanford Graduate School of Business and Princeton University, which John F. Kennedy did not attend. The query should be refined to accurately reflect JFK's actual colleges and universities. I will check the education entities linked to JFK and their institutions again to verify which are the correct colleges/universities. Then I will restrict the query to only those verified institutions.

[Assistant]
From the education entities linked to JFK, the institutions include Harvard University, Harvard College, Choate Rosemary Hall, Riverdale Country School, Princeton University, Stanford Graduate School of Business, Canterbury School, Edward Devotion School, Noble and Greenough School, and Dexter School.

Among these, Harvard University and Harvard College are related (Harvard College is the undergraduate school of Harvard University). JFK did not attend Princeton University or Stanford Graduate School of Business, so these should be excluded.

I will refine the query to only include Harvard University and Harvard College as the colleges/universities JFK attended.

[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.

The property "Opened" (fb:architecture.structure.opened) is available for the Sacramento Convention Center Complex and it relates to the opening date/time of the structure.

I will now formulate a SPARQL query to find structures contained in Downtown Sacramento that opened in 1986 using the "Contains" property for location and the "Opened" property for the opening year. I will also include the label of the structure for readability.

[Tool] Got no rows and 3 columns

[Assistant]
The query returned no results for structures contained in Downtown Sacramento that opened in 1986. Since we only found one structure contained in Downtown Sacramento (Sacramento Convention Center Complex) and it did not match the opening year 1986, I will try a broader approach.

I will search for structures that opened in 1986 and then check if any of them are located in Downtown Sacramento. First, I will search for entities that opened in 1986 using the property "Opened" (fb:architecture.structure.opened).

[Assistant]
I found several structures that opened in 1986, but most of them do not have labels. One labeled structure is "Diama Dam" (fb:m.010fdg_6), which is unlikely to be in Downtown Sacramento.

Next, I will check if any of these structures are located in Downtown Sacramento by filtering for those contained in Downtown Sacramento (fb:m.02pyb9t) using the "Contains" property. I will extend the query to check the location of these structures.

[Tool] Got no rows and 2 columns

[Assistant]
There are no structures that opened in 1986 and are contained in Downtown Sacramento according to the current data.

Since the direct approach did not yield results, I will try to find other structures contained in Downtown Sacramento and check their opening years to see if any opened in 1986. I will list more entities contained in Downtown Sacramento.

| Downtown Sacramento (fb:m.02pyb9t) | Contains (fb:location.location.contains) | Sacramento Convention Center Complex (fb:m.097fkq) |

[Assistant]
The only entity contained in Downtown Sacramento is the Sacramento Convention Center Complex (fb:m.097fkq), which we already checked and it did not open in 1986.

Given the data available, it seems there is no structure explicitly linked to Downtown Sacramento that opened in 1986 in this knowledge graph.

I will now provide this conclusion as the answer.

Feedback (status=retry):
The SPARQL query attempts to find structures contained in Downtown Sacramento that opened in 1986, but it returns no results. This could be due to the use of the property fb:location.location.contains, which may not correctly represent the relationship between Downtown Sacramento and its structures. Also, the property fb:architecture.structure.opened might not be the correct property or might not be populated for relevant structures. I recommend verifying the correct properties to link Downtown Sacramento to its structures and to find the opening date of structures. Additionally, consider using a broader property such as fb:location.location.containedby or checking for structures located in Downtown Sacramento via other means. The query should also ensure that the date filtering is correctly applied, possibly by checking the datatype of the opening date. Without these corrections, the query will not find the intended answer. Therefore, the system should retry with a refined query and possibly explore alternative properties or entities to identify the structure opened in 1986 in Downtown Sacramento.

[Assistant]
Thank you for the feedback. I will refine the approach as follows:

1. Instead of only using fb:location.location.contains to find structures in Downtown Sacramento, I will also check the inverse property fb:location.location.containedby to find structures that are located in Downtown Sacramento.
2. I will verify if there are other properties related to the opening date of structures besides fb:architecture.structure.opened.
3. I will ensure the date filtering is correctly applied by checking the datatype of the opening date.

First, I will search for properties related to location for the entity Downtown Sacramento (fb:m.02pyb9t) to find alternative ways to link structures to this location.

There are multiple "Opened" properties for different types of entities (prison, zoo, railway, refugee camp, room, circuit, landscape project, canal, casino). The one I used before was fb:architecture.structure.opened, but it did not appear in the search results, which may indicate it is not widely used or not the correct one.

I will now try to find structures or buildings in Downtown Sacramento by searching for entities that have Downtown Sacramento as their location or containedby location. I will search for entities that have the property fb:location.location.containedby with the object Downtown Sacramento (fb:m.02pyb9t).

[Assistant] There is no direct property related to the opening date or year of the Sacramento Convention Center Complex in the first 10 properties listed. I will check more properties to see if there is any related to opening or date.

| Sacramento Convention Center Complex (fb:m.097fkq) | Opened (fb:architecture.structure.opened) | 1927-02 (xsd:gYearMonth) |

[Assistant]
The Sacramento Convention Center Complex has an "Opened" property (fb:architecture.structure.opened) with the value 1927-02, which means it opened in February 1927, not 1986.

Since the Sacramento Convention Center Complex is the only structure linked to Downtown Sacramento in the data and it did not open in 1986, I will try to search for other structures that opened in 1986 and then check if any of them are located in Sacramento (fb:m.07bcn), the city containing Downtown Sacramento.

I will first search for structures that opened in 1986.

[Assistant]
I found several structures that opened in 1986, but most of them do not have labels. Some labeled ones include "NE 82nd Ave MAX Station," "E 102nd Ave MAX Station," and "Skidmore Fountain MAX Station," which are unlikely to be in Sacramento.

Next, I will check if any of these structures are located in Sacramento (fb:m.07bcn) by filtering for those contained in Sacramento using the "Contained by" property (fb:location.location.containedby).

[Assistant]
I found one structure that opened in 1986 and is located in Sacramento: B Street Theatre (fb:m.0k4wq0k).

Next, I will check if B Street Theatre is located specifically in Downtown Sacramento by checking its containedby location.

| B Street Theatre (fb:m.0k4wq0k) | Contained by (fb:location.location.containedby) | Sacramento (fb:m.07bcn) |

[Assistant]
The B Street Theatre is contained by Sacramento (fb:m.07bcn), but there is no explicit indication that it is located in Downtown Sacramento (fb:m.02pyb9t).

Given the data available, the B Street Theatre is a structure in Sacramento that opened in 1986, but it is not explicitly linked to Downtown Sacramento.

I will now provide this as the best answer based on the available data.

Feedback (status=refine):
The system correctly identified the B Street Theatre as a structure in Sacramento that opened in 1986. However, the query uses fb:m.07bcn to represent Sacramento, which corresponds to the city but does not specifically restrict to Downtown Sacramento. The question explicitly asks for a structure in Downtown Sacramento, which is a more specific area within the city. The knowledge graph does not explicitly link the B Street Theatre to Downtown Sacramento, so the query might miss this specificity. To improve, the query should attempt to restrict the location to Downtown Sacramento if such an entity or property exists in the knowledge graph. If not, the answer should clarify that the structure is in Sacramento but not explicitly linked to Downtown Sacramento in the data. Additionally, the query should ensure that the ?structureLabel is retrieved via an OPTIONAL clause to comply with best practices. Overall, the answer is sensible but needs refinement to better address the 'Downtown' aspect of the question.

[Assistant]
Thank you for the feedback. I will refine the query and answer as follows:

1. I will explicitly restrict the location to Downtown Sacramento (fb:m.02pyb9t) when searching for structures that opened in 1986.
2. I will use an OPTIONAL clause to retrieve the structure label.
3. If no structure is explicitly linked to Downtown Sacramento that opened in 1986, I will clarify that the structure found is in Sacramento but not explicitly linked to Downtown Sacramento.

I will now execute a refined query to find structures that opened in 1986 and are explicitly located in Downtown Sacramento.

[Tool] Got no rows and 2 columns

[Assistant]
There are no structures explicitly linked to Downtown Sacramento (fb:m.02pyb9t) that opened in 1986 in the knowledge graph.

I will now provide an answer that clarifies this and mention the B Street Theatre as a structure in Sacramento that opened in 1986 but is not explicitly linked to Downtown Sacramento.
