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 was Caesar murdered?

10. Riverdale, also known as Riverdale, ND, Riverdale, North Dakota (wd:Q2373536): human settlement in McLean County, North Dakota, United States of America

[Assistant]
The most relevant entity for "Riverdale" (the TV show) is wd:Q23001951, which is described as an American teen drama television series (2017–2023).

Next, I need to find the property that represents "first aired" or "original air date". I will search for properties related to "air date".

[Assistant]
The most relevant property for "first aired" is "publication date" (wdt:P577), which is used for the date or point in time when a work was first published or released.

Now, I will construct a SPARQL query to get the publication date of Riverdale (wd:Q23001951). Since the user asked for the year, I will extract the year from the publication date.

Let's write the query to get the year Riverdale first aired.

[Tool] Got no rows and 2 columns

[Assistant]
It appears that querying for the publication date (wdt:P577) of Riverdale (wd:Q23001951) returned no results. This could mean that the property used for the air date of TV series might be different, or it could be stored as a qualifier on a statement.

To investigate further, I will list all properties used for Riverdale (wd:Q23001951) to see if there is a more specific property for "original air date" or something similar.

[Assistant]
From the listed properties, I see that "start time" (wdt:P580) is used with the value "2017-01-26T00:00:00Z". This likely represents the date when Riverdale first aired.

To answer the user's question, I will extract the year from this "start time" property.

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 you call a female form of an emperor in English?

[Assistant]
Let's break down the question:

1. The user is asking for the English term for the female form of an "emperor."
2. The entity "emperor" is likely represented in Wikidata.
3. We need to find the property that links "emperor" to its female equivalent or feminine form.
4. We should search for the entity "emperor" and then look for properties like "feminine form of label" or similar.

First, I will search for the entity "emperor" in Wikidata.

[Assistant]
The most relevant entity for "emperor" as a type of monarch is wd:Q39018 ("emperor, also known as empress, imperator").

Next, I need to find the property that links an entity to its female or feminine form. I will search for properties related to "feminine form" or "female form".

[Assistant]
The property "female form of label" (wd:P2521) is the most relevant for finding the feminine form of a title or label.

Next, I will check if the entity "emperor" (wd:Q39018) has a value for the property "female form of label" (wd:P2521).

Feedback (status=retry):
The SPARQL query is incorrect because it attempts to retrieve the female form as a string label using the property P2521, but P2521 links to an entity (the feminine form), not a string. The query should return the IRI of the feminine form ("empress"), not just its label, to comply with the requirement that queries return identifiers. Additionally, the FILTER(LANG(?femaleForm) = "en") is not appropriate here, as ?femaleForm is expected to be an entity, not a string literal. The correct query should be:

SELECT ?femaleForm WHERE { wd:Q39018 wdt:P2521 ?femaleForm . }

Optionally, to get the English label, you can add an OPTIONAL clause:

OPTIONAL { ?femaleForm rdfs:label ?femaleFormLabel . FILTER(LANG(?femaleFormLabel) = "en") }

Please revise the query accordingly.

[Assistant]
Thank you for the feedback. You are correct: the property wdt:P2521 links to an entity (the feminine form, "empress") rather than a string label, so the query should return the IRI of the feminine form. The FILTER(LANG(...)) is not appropriate for an entity IRI. To comply with the requirements, I will revise the query to return the IRI of the feminine form, and optionally include the English label.

Here is the revised query:

SELECT ?femaleForm ?femaleFormLabel WHERE {
  wd:Q39018 wdt:P2521 ?femaleForm .
  OPTIONAL { ?femaleForm rdfs:label ?femaleFormLabel . FILTER(LANG(?femaleFormLabel) = "en") }
}

This will return the IRI for the feminine form of "emperor" and, if available, its English label.

Now, I will provide the final answer.

Feedback (status=retry):
The SPARQL query retrieves all language-specific feminine forms of 'emperor' from Wikidata, but it does not filter for the English form. As a result, the answer is not based on the SPARQL result, which contains many non-English terms. The query should include a filter for the English label (e.g., FILTER(LANG(?femaleFormLabel) = "en")), and the result should be checked to ensure that 'empress' is returned as the English feminine form. Please revise the query to return only the English feminine form and its IRI.

[Assistant]
Thank you for the feedback. You are correct: to ensure that only the English feminine form is returned, the query should filter for the English label of the feminine form.

Here’s my step-by-step plan:
1. Query for the feminine form entity of "emperor" (wd:Q39018) using wdt:P2521.
2. Retrieve the rdfs:label of that entity.
3. Filter the label to only include English (LANG(?femaleFormLabel) = "en").
4. Return both the IRI and the English label.

Here is the revised SPARQL query:

SELECT ?femaleForm ?femaleFormLabel WHERE {
  wd:Q39018 wdt:P2521 ?femaleForm .
  ?femaleForm rdfs:label ?femaleFormLabel .
  FILTER(LANG(?femaleFormLabel) = "en")
}

Now, I will provide the final answer based on this query.

[User] Who is the current president of the German Bundestag currently?

[Assistant]
Let's break down the question:

1. The user is asking for the current president of the German Bundestag.
2. We need to identify:
   - The entity for the German Bundestag.
   - The property for "president" (likely "head of" or "president").
   - How to filter for the current officeholder.

First, I'll search for the entity "German Bundestag".

[Assistant]
The main entity for the German Bundestag is wd:Q154797.

Next, I need to find the property that links the Bundestag to its president. This is likely "head of", "president", or a similar property. I'll search for properties related to "president" for the German Bundestag entity.

No other items found

[Assistant]
The most relevant property for "president" is "chairperson" (wdt:P488), which is described as "presiding member of an organization, group or body, director / manager, significant person". This matches the role of the president of the Bundestag.

Now, to find the current president, I need to check if there are qualifiers indicating the time period (start and end dates) for the chairperson. This will allow me to filter for the current officeholder (where there is no end date or the end date is in the future).

I'll list some statements for the German Bundestag with the property "chairperson" (P488) to see how the data is structured.

Feedback (status=refine):
The SPARQL query correctly attempts to find the current president of the German Bundestag by selecting statements without an end time. However, the result includes two people: Bärbel Bas (wd:Q1019016) and Julia Klöckner (wd:Q88158). The answer only mentions Bärbel Bas, which is inconsistent with the query result. The answer should either mention both individuals or the query should be refined to ensure only the current president is returned. Please verify the data or refine the query to ensure only the actual current president is selected, possibly by checking for the most recent start date or clarifying the data.

[Assistant]
Thank you for your feedback. The issue is that the query returns two people as "current" presidents because both have statements without an end date. To refine the answer, I need to ensure that only the most recent president is selected, which can be done by choosing the statement with the latest start date.

Here's my plan:
- For each chairperson statement without an end date, get the start date.
- Select the one with the most recent (maximum) start date as the current president.

I will now write and execute a SPARQL query that implements this logic.

[Tool] Got no rows and 1 columns

[Assistant]
The refined query, which selects the president with the most recent start date among those without an end date, returned no results. This suggests that there may be an issue with the data structure or that the start date qualifier is not present for all statements.

To debug, I will:
- List all chairperson statements for the German Bundestag, including their start and end dates, to see the data structure and values.
- This will help clarify which statement is the most recent and if there are missing qualifiers.

Let me run a query to list all presidents, their start and end dates.

[Assistant]
From the results, Julia Klöckner (wd:Q88158) has a start date of 2025-03-25 with no end date, and Bärbel Bas (wd:Q1019016) has a start date of 2021-10-26 with no end date. However, as of now (2024), the date for Julia Klöckner is in the future, so the actual current president should be Bärbel Bas.

To ensure the query only returns the president whose start date is the most recent but not in the future, I will add a filter to only include start dates less than or equal to today.

Let me construct and run this improved query.

[Tool] Got no rows and 1 columns

[Assistant]
The query with the NOW() filter returned no results. This suggests that the endpoint may not support the NOW() function, or there may be a syntax issue.

To work around this, I will use a fixed date (e.g., "2024-06-01") as the current date, since the knowledge cutoff is June 2024. I will filter for start dates less than or equal to this date and select the most recent one.

Let me adjust the query accordingly.

Feedback (status=retry):
The SPARQL query is attempting to find the current president of the German Bundestag by looking for a statement with property P488 (chairperson/president) that has a start date but no end date. However, the query returns no results, which means it did not find a current president. This could be due to the way the query is structured or the data in Wikidata. Additionally, the query is overly complex for the task: the second FILTER NOT EXISTS block is unnecessary if we simply look for the statement with no end date and the latest start date. Also, the query should return the IRI of the president, but it does not include optional labels, which could be helpful. Please revise the query to ensure it returns the current president's IRI and optionally their label, and check for the correct use of properties and filters.

[Assistant]
Thank you for the feedback. Let's simplify and clarify the approach:

1. We want the current president of the German Bundestag (wd:Q154797).
2. The property for president is "chairperson" (P488).
3. The current president is the one with no end date (P582) and the latest start date (P580).
4. We should return the IRI and optionally the label.

A simpler and robust approach is:
- Select all statements with no end date.
- Get their start dates.
- Return the one with the latest start date.

Let me write a query that:
- Gets all presidents with no end date.
- Orders by start date descending.
- Limits to 1 result (the most recent/current).
- Optionally includes the label.

Here is the revised query:
