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 is the second game developed by Piranha Bytes?

[Assistant]
Let's break down the question:

1. The entity "Piranha Bytes" is likely a video game developer.
2. The question asks for the "second game developed" by them, which implies:
   - Find all games developed by Piranha Bytes.
   - Order them by release date.
   - Return the second one.

First, I will search for the entity "Piranha Bytes" in Wikidata to get its identifier.

[Tool]
Top 10 entity alternatives:
1. Piranha Bytes (wd:Q677273): German video game development company
2. piranha, also known as piraña, Serrasalmus nattereri (wd:Q185215): group of fish
3. Piranha 3D, also known as Piranha (wd:Q733995): 2010 film directed by Alexandre Aja

9. Piranha (wd:Q4394050): single by The Grace
10. Piranha (wd:Q3389104): fictional comic book character

[Assistant]
The correct entity for "Piranha Bytes" is wd:Q677273, which is a German video game development company.

Next, I need to find all games developed by Piranha Bytes. I will search for properties related to "developed by" or "developer" to identify the correct property to use.

[Tool]
Top 10 property alternatives:

[Assistant]
The property "developer" (wd:P178) is the correct one to use for finding games developed by Piranha Bytes.

Now, I will write a SPARQL query to find all items where Piranha Bytes (wd:Q677273) is the developer, get their release dates, and order them chronologically to find the second game. I will also try to get the label and release date for context.

First, I will check which property is used for "release date" in Wikidata.

[Tool]
Top 10 property alternatives:
1. date of commercialization, also known as availability date, commercialization date, product release date, release date (wd:P5204 as pr/prn/ps/pqn/p/pqv/pq/psn/prv/wdtn/psv/wdt): date when a product was first commercialized

[Assistant]
The property "publication date" (wd:P577) is commonly used for the release date of works, including video games.

Now, I will construct a SPARQL query to:
- Find all items where Piranha Bytes (wd:Q677273) is the developer (wdt:P178).
- Get their publication date (wdt:P577).
- Order them by publication date.
- Return the second game in that order.
- Optionally get the label and publication date for context.

Here is the query I will use.

Feedback (status=done):
The SPARQL query correctly retrieves all games developed by Piranha Bytes, orders them by publication date, and selects the second one using OFFSET 1 LIMIT 1. The query returns the actual IRI of the game, and the answer matches the expected result. No further refinement is needed.

[User] On how many albums does Mariah Carey perform?

[Assistant]
First, I need to identify the entity for "Mariah Carey" and the property that links a performer to albums. Then, I need to determine what qualifies as an "album" in Wikidata (likely an instance of "album" or "music album").

Step 1: Search for the entity "Mariah Carey".

10. Why Mariah Carey Matters (wd:Q131160633): book written by Andrew Chan

[Assistant]
The correct entity for Mariah Carey the singer is wd:Q41076.

Next, I need to find the property that links a performer (such as Mariah Carey) to albums. Common properties for this are "performer", "contributor", or "artist". I will search for properties related to "performer".

[Tool]
Top 10 property alternatives:
1. performer, also known as actor, sung by, singer, recording by, recorded by (wd:P175 as pr/prn/ps/pqn/p/pqv/pq/psn/prv/wdtn/psv/wdt): actor, musician, band or other performer associated with this role or musical work, contributor to the creative work or subject

[Assistant]
The property "performer" (wd:P175) is the most relevant, as it links a performer to a creative work such as an album.

Now, I need to determine how to identify "albums" in Wikidata. Typically, albums are instances of "album" or "music album". I will search for the entity "album" to confirm its QID.

[Tool]
Top 10 entity alternatives:
1. album, also known as full album, record album, music album, full-length album, audio album (wd:Q482994): grouping of album releases by an artist usually released at the ...racks but in different formats for consumption (digital, CD, LP)

10. Album (wd:Q4712765): 2002 Tamil film directed by Vasanthabalan

[Assistant]
The correct entity for a music album is wd:Q482994.

Now, to answer the question, I need to count how many albums (instances of wd:Q482994) have Mariah Carey (wd:Q41076) as a performer (wd:P175).

I will construct a SPARQL query that counts the number of such albums.

[Tool]
Got 1 row and 1 column:

[User]
Feedback (status=done):
The SPARQL query correctly counts the number of distinct albums (wd:Q482994) on which Mariah Carey (wd:Q41076) is listed as a performer (wdt:P175). The query returns the actual count as requested, and the answer is consistent with the question. No further refinement is necessary.

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.

Feedback (status=refine):
The SPARQL query correctly identifies which character died later by comparing their dates of death, which is a reasonable proxy for 'lived longer' in the context of fictional characters. However, the query only returns the character who died last, not both characters with their respective dates of death. For full transparency and to allow the user to see both dates, the query should return both characters and their dates of death, and then the answer can state who lived longer based on the data. This would make the answer more informative and robust.

[Assistant]
Thank you for the feedback. I understand that for full transparency, the SPARQL query should return both Sirius Black and Bellatrix Lestrange along with their respective dates of death, so the user can see the data directly. I will adjust the query accordingly.

Here’s my thought process:
- I will select both characters and their dates of death.
- I will also include their labels for clarity (optionally).
- The answer will state who lived longer, based on the returned dates.

Here is the improved SPARQL query and answer:

Feedback (status=done):
The answer is correct and complete. The SPARQL query retrieves the date of death for both Sirius Black and Bellatrix Lestrange, and the answer correctly compares the dates to determine who lived longer. The query returns the IRIs for both characters as required, and the use of optional labels is appropriate. No further refinement is needed.

[User] How many countries have never been members of the UN?

[Assistant]
Let's break down the question:

1. We need to find all countries (entities that are considered sovereign states).
2. We need to find which of these have never been members of the United Nations (UN).

Step 1: Identify the entity for "country" or "sovereign state" in Wikidata.
Step 2: Identify the property for "member of" or "membership" in Wikidata.
Step 3: Identify the entity for "United Nations" in Wikidata.
Step 4: Construct a query to find all countries that are not now and have never been members of the UN.

Let's start by searching for the entity "United Nations".

[Tool]
Top 10 entity alternatives:
1. United Nations, also known as the U.N., the UN, U.N., UN, United Nations Organization (wd:Q1065): global international and intergovernmental organization
2. United Nations (wd:Q7888317): American band
3. United Nations (wd:Q7888316): United Nations album
4. United Nations (wd:Q7888314): Rui En album
5. United Nations, also known as Canadian United, Canada United, Global United Nations Syndicate (wd:Q7888319): criminal gang who started in Vancouver, British Columbia
6. United Nations (wd:Q74063664): print in the National Gallery of Art (NGA 64023)
7. United Nations, also known as q Sm514 United Nations (wd:Q104713070): subject category of the 20th Century Press Archives
8. United Nations, also known as Star Trek UN, Star Trek United Nations, UN (wd:Q111240888): United Nations as depicted in the Star Trek multiverse
9. United Nations (wd:L620589-S1)
10. United Nations (wd:L618606-F1)

[Assistant]
The correct entity for the United Nations is wd:Q1065.

Next, let's identify the property for "member of" or "membership" in Wikidata, as we need to find which countries have been members of the UN.

[Tool]
Top 10 property alternatives:
1. member of political party, also known as political party member, political party, party membership, party, member of party (wd:P102 as pr/prn/ps/pqn/p/pqv/pq/psn/prv/wdtn/psv/wdt): the political party of which a person is or has been a member or otherwise affiliated, member of
2. member of, also known as band member of, membership, member of musical group, in musical group, be member of (wd:P463 as pr/prn/ps/pqn/p/pqv/pq/psn/prv/wdtn/psv/wdt): organization, club or musical group to which the subject belongs...ical position, such as a member of parliament (use P39 for that), part of
3. members have occupation, also known as profession of members, organization of, organization for, organisation of, organisation for (wd:P3989 as pr/prn/ps/pqn/p/pqv/pq/psn/prv/wdtn/psv/wdt): some or all members of this group share the occupation
4. member count, also known as total members, number of members, count of members, amount of members, membership (wd:P2124 as pr/prn/ps/pqn/p/pqv/pq/psn/prv/wdtn/psv/wdt): number of entities that are part of an organization at a particular time
5. contains the administrative territorial entity, also known as has shires, has rural cities, has regions, has municipalities, has members (wd:P150 as pr/prn/ps/pqn/p/pqv/pq/psn/prv/wdtn/psv/wdt): (list of) direct subdivisions of an administrative territorial entity, has part(s)
6. has part(s), also known as has component, incorporates, has ingredient, has ingredients, has member (wd:P527 as pr/prn/ps/pqn/p/pqv/pq/psn/prv/wdtn/psv/wdt): part of this subject; inverse property of "part of" (P361). See also "has parts of the class" (P2670).
7. affiliation, also known as association, sister society, affiliated with, affiliated to, associated with (wd:P1416 as pr/prn/ps/pqn/p/pqv/pq/psn/prv/wdtn/psv/wdt): organization that a person or organization is affiliated with (not necessarily member of or employed by)
8. member category, also known as category for members (wd:P6365 as pr/prn/ps/pqn/p/pqv/pq/psn/prv/wdtn/psv/wdt): category item for members of the organization
9. represented by, also known as agent, managed by, manager, managing agent, rep (wd:P1875 as pr/prn/ps/pqn/p/pqv/pq/psn/prv/wdtn/psv/wdt): person or agency that represents or manages the subject

[Assistant]
The property "member of" (wd:P463) is the most appropriate for indicating membership in an organization such as the United Nations.

Now, we need to identify the entity for "country" or "sovereign state" in Wikidata, so we can filter for all countries.

[Tool]
Top 10 entity alternatives:
1. sovereign state, also known as country, nation, sovereign country, sovereign nation, Westphalian state (wd:Q3624078): state that has the highest authority over a territory
2. country, also known as host country, state, sovereign state, land (wd:P17): sovereign state that this item is in (not to be used for human beings)
3. sovereign state (wd:L642577-S2)
4. Westphalian sovereignty, also known as state sovereignty, Westphalian system (wd:Q442402): concept of the sovereignty of nation-states in Europe
5. state sovereignty, also known as national sovereignty (wd:Q56350990)
6. The Sovereign State (wd:Q7765603): book by Anthony Sampson
7. China (sovereign state) (wd:L1012856-S1)
8. state (sovereign polity) (wd:L1216603-S1)
9. state (sovereign polity) (wd:L1220881-S1)
10. State Sovereignty Day (wd:Q130322685): Day commemorated in honor of the restoration of the sovereignty of the Republic of Azerbaijan following the Anti-Terror Operation

[Assistant]
The entity for "sovereign state" is wd:Q3624078, which is also referred to as "country" in Wikidata.

Now, to find all countries that have never been members of the United Nations, we need to:
- Select all entities that are instances of "sovereign state" (wd:Q3624078).
- Exclude those that have a "member of" (wd:P463) relationship with the United Nations (wd:Q1065).

Let's construct a SPARQL query that counts the number of such countries.

Got 1 row and 1 column:
| count       |

[User]
Feedback (status=refine):
The query is mostly correct: it counts the number of entities that are instances of 'sovereign state' (wd:Q3624078) and have never been members of the United Nations (wd:Q1065). However, there are a few points to consider for further refinement:

1. The definition of 'sovereign state' in Wikidata may include historical or unrecognized entities. It would be better to ensure that only currently existing countries are counted. This can be done by filtering out entities with an end date (P576) or those that are marked as 'no longer exists' (P31 wd:Q3024240 for 'former country').
2. Optionally, you could include labels for the countries in an OPTIONAL clause for transparency, though this is not required for a count.

Suggestion: Refine the query to only include currently existing sovereign states by excluding those with an end date or marked as former countries.

[Assistant]
Thank you for the feedback. To refine the query:

1. We need to exclude entities that are marked as "former country" (wd:Q3024240) via instance of (P31).
2. We should also exclude entities that have an end date (P576), as these are not currently existing.
3. We will keep the main logic: select all sovereign states (wd:Q3624078) that have never been members of the United Nations (wd:Q1065).

Let's construct the refined query:

- ?country wdt:P31 wd:Q3624078 (sovereign state)
- FILTER NOT EXISTS { ?country wdt:P463 wd:Q1065 } (never a UN member)
- FILTER NOT EXISTS { ?country wdt:P31 wd:Q3024240 } (not a former country)
- FILTER NOT EXISTS { ?country wdt:P576 ?end } (no end date)

I will now execute this refined query.

Feedback (status=done):
The SPARQL query correctly identifies currently existing sovereign states that have never been members of the United Nations by filtering for entities that are instances of 'sovereign state', excluding those that are members of the UN, excluding historical countries, and excluding dissolved entities. The answer and explanation are accurate and complete for the question asked.

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] Who wrote the Erlangen program?

[Assistant]
Let's break down the question:

[Assistant]
The most relevant entity is "Erlangen program" (wd:Q315296), which is a research program on the symmetries of geometry.

Next, I need to find the property that links a work to its author or writer. I will search for properties related to "author" or "writer".

[Tool]
Top 10 property alternatives:

[Assistant]
The most relevant property for the author of a written work is "author" (wd:P50).

Now, I will check if the "Erlangen program" (wd:Q315296) has an "author" (wdt:P50) property, and retrieve the value.

[Tool] Got no rows and 3 columns

[Assistant]
It appears that the "author" property (wdt:P50) is not set for the "Erlangen program" (wd:Q315296) in Wikidata.

However, sometimes other properties such as "theorized by" or "creator" might be used for mathematical or scientific works. I will check if "theorized by" (wd:P8403) or "creator" (wd:P170) is used for this entity.

First, I'll check "theorized by" (wd:P8403).

[Tool] Got no rows and 3 columns

[Assistant]
The "theorized by" property (wdt:P8403) is also not set for the "Erlangen program" (wd:Q315296).

Next, I will check the "creator" property (wdt:P170) for this entity.

[Tool] Got no rows and 3 columns

[Assistant]
None of the properties "author" (wdt:P50), "theorized by" (wdt:P8403), or "creator" (wdt:P170) are set for the "Erlangen program" (wd:Q315296) in Wikidata.

To be thorough, I will list all direct properties and values for "Erlangen program" to see if any other relevant property is used to indicate its author or originator.

[Assistant]
The direct properties for "Erlangen program" do not include any person or entity that could be interpreted as its author or originator. The properties are mostly identifiers and classification information.

Given that the author is not explicitly stated in Wikidata for this entity, I cannot provide a SPARQL query that returns the author directly from the data.

Would you like me to attempt to find related works or references that might mention the author, or would you prefer to stop here?

This refined query counts fictional female swordfighters in Wikidata, including all subclasses of 'female' and all subclasses of swordfighter, fencer, musketeer, and samurai, across the main occupation/role properties. This should be the most robust and comprehensive count possible with current Wikidata modeling.

"Occupation" (wd:P106) is the correct property to use for linking a character to "swordfighter".

Now, let's construct a SPARQL query to count the number of fictional female swordfighters:
- ?character wdt:P31 wd:Q95074 (instance of fictional character)
- ?character wdt:P21 wd:Q6581072 (gender female)
- ?character wdt:P106 wd:Q11397897 (occupation swordfighter)

We will use COUNT to get the number of such characters.

Feedback (status=refine):
The query is mostly correct but could be improved. The use of 'occupation: swordfighter' (wd:Q11397897) may not be widely populated for fictional characters, as many fictional swordfighters may not have this occupation explicitly set in Wikidata. Additionally, the query restricts to 'instance of: fictional character' (wd:Q95074), which is good, and 'sex or gender: female' (wd:Q6581072), which is also correct. However, to be more comprehensive, consider including subclasses of swordfighter (e.g., swordswoman, swordsman, etc.) and possibly checking for relevant properties like 'notable for' or 'has role' that might be used for fictional characters. Also, ensure that the occupation property is used for fictional characters in Wikidata, as sometimes roles are modeled differently. The answer is correct for the current query, but the query could be refined for broader coverage.

[Assistant]
Thank you for the feedback! Here’s how I’ll refine the approach:

**Thought Process:**
1. The occupation "swordfighter" (wd:Q11397897) may not be widely used for fictional characters. Some may use related occupations (e.g., swordsman, swordswoman, fencer) or roles (e.g., "has role", "notable for").
2. To be more comprehensive, I should:
   - Include subclasses of "swordfighter" (e.g., swordsman, swordswoman, fencer).
   - Consider alternative properties like "has role" (P2868) and "notable for" (P800).
3. I’ll first find subclasses of "swordfighter" and related occupations.
4. Then, I’ll check if "has role" or "notable for" are used with these entities.
5. Finally, I’ll build a query that covers all these cases.

Let’s start by finding subclasses of "swordfighter" (wd:Q11397897).

[Assistant]
I have now gathered a comprehensive set of relevant occupations and subclasses for swordfighters, including:
- swordfighter (wd:Q11397897) and its subclasses (Japanese swordmaster, wd:Q10899181; wd:Q11481823)
- fencer (wd:Q13381863) and its subclasses (sabre fencer, wheelchair fencer, fencing master, foil fencer, épée fencer)
- musketeer (wd:Q721960) and its subclass (Musketeers of the Guard, wd:Q1564383)
- samurai (wd:Q38142) and its many subclasses (ronin, jizamurai, etc.)

Additionally, I have identified alternative properties that might be used for fictional characters:
- occupation (P106)
- subject has role (P2868)
- notable role (P10606)

To maximize coverage, I will construct a query that:
- Selects fictional characters (wd:Q95074)
- With gender female (wd:Q6581072)
- Who have any of the relevant occupations or roles (using P106, P2868, or P10606)
- Where the value is any of the above swordfighter-related entities or their subclasses

Let me now build the refined SPARQL query.

[User]
Feedback (status=refine):
The query is comprehensive in its coverage of swordfighter-related occupations and roles, and it correctly restricts to fictional female characters. However, there are a few refinements that could improve accuracy and completeness:

1. The query currently only considers characters whose gender is explicitly set to 'female' (wd:Q6581072). Some fictional characters may have 'sex or gender' set to 'woman' (wd:Q467), which is a subclass of 'female', or other related values. Consider including subclasses of 'female' to be more inclusive.
2. The query does not account for possible missing or alternative occupation/role properties. While the main ones are covered, it's worth checking if there are other relevant properties (e.g., 'character role' P453) that could be included.
3. The list of swordfighter-related occupations is extensive, but it may still miss some relevant subclasses. Consider using a property path to include all subclasses of 'swordfighter' and related occupations.

Overall, the query is sensible and mostly correct, but a few refinements could make it more robust and comprehensive.

[Assistant]
Thank you for the detailed feedback! Here’s how I’ll refine the query further:

**Thought Process:**
1. For gender, I should include not only "female" (wd:Q6581072) but also all subclasses (e.g., "woman" wd:Q467). I can do this with a property path: ?character wdt:P21/wdt:P279* wd:Q6581072.
2. For swordfighter-related occupations/roles, instead of hardcoding all subclasses, I can use a property path: ?occupation wdt:P279* wd:Q11397897 (and similarly for fencer, musketeer, samurai, etc.).
3. For properties, in addition to occupation (P106), subject has role (P2868), and notable role (P10606), I should consider "character role" (P453) as well.
4. The query should select fictional characters (wd:Q95074) with any of these properties pointing to any subclass of swordfighter, fencer, musketeer, or samurai, and whose gender is any subclass of female.

Let’s build this robust query.
