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] Give me all Dutch parties.

[Assistant]
To answer this question, I need to identify entities that are political parties and are Dutch (from the Netherlands).

Step 1: Find the entity for the Netherlands.
Step 2: Find the property that links a party to a country (such as "country", "location", or "nationality").
Step 3: Find the class or type for political parties.
Step 4: Combine these to get all political parties associated with the Netherlands.

Let's start by searching for the entity "Netherlands".

[Tool]
Top 10 entity alternatives:
1. Netherlands (dbr:Netherlands): The Netherlands (Dutch: Nederland [ˈneːdərlɑnt] (listen)), also ...rs in the North Sea with those countries and the United Kingdom.
2. No. 320 (Netherlands) Squadron RAF, also known as Netherlands (<http://dbpedia.org/resource/No._320_(Netherlands)_Squadron_RAF>): No. 320 (Netherlands) Squadron RAF was a unit of the Royal Air F...d from the personnel of the Royal Netherlands Naval Air Service.
3. No. 321 (Dutch) Squadron RAF, also known as Netherlands (<http://dbpedia.org/resource/No._321_(Dutch)_Squadron_RAF>): No. 321 (Dutch) Squadron RAF was a unit of the Royal Air Force d...luchtvaartdienst (MLD), the Royal Netherlands Naval Air Service.
4. Netherlands (<http://dbpedia.org/resource/Category:Netherlands>)
5. NETHERLANDS (dbr:NETHERLANDS)
6. netherlands (dbp:netherlands)
7. Netherlands Antilles (dbr:Netherlands_Antilles): The Netherlands Antilles (Dutch: Nederlandse Antillen, pronounce...ch colony of Curaçao and Dependencies and was dissolved in 2010.
8. Ede, Netherlands (<http://dbpedia.org/resource/Ede,_Netherlands>)
9. Limburg (Netherlands) (<http://dbpedia.org/resource/Limburg_(Netherlands)>): Limburg (Dutch pronunciation: [ˈlɪmbʏrx] (listen)) is the southe...national border with the German state of North Rhine-Westphalia.
10. Grave, Netherlands (<http://dbpedia.org/resource/Grave,_Netherlands>): Grave (Dutch: [ˈɣraːvə] (listen), formerly De Graaf) is a munici...he following towns : Grave (capital), Velp, Escharen and Gassel.

[Assistant]
The main entity for the Netherlands is dbr:Netherlands.

Next, I need to find the class or type for "political party" and a property that links a party to a country (likely "country" or "location"). I'll start by searching for the class "political party".

[Tool]
Top 10 entity alternatives:
1. Political party (dbr:Political_party): A political party is an organization that coordinates candidates...veloped and spread around the world over the last few centuries.
2. political party (dbo:PoliticalParty): for example: Democratic_Party_(United_States)
3. Political Party (dbr:Political_Party)
4. Party Political (dbr:Party_Political)
5. Party political (dbr:Party_political)
6. political party (dbp:politicalParty)
7. political party. (dbp:politicalParty.)
8. Reformed Political Party (dbr:Reformed_Political_Party): The Reformed Political Party (Dutch: Staatkundig Gereformeerde P...has won between 1.6% and 2.5% of the votes in general elections.
9. Vox (political party) (<http://dbpedia.org/resource/Vox_(political_party)>): Vox (Latin for "voice", often stylized as VOX; Spanish pronunciation: [ˈboks]) is a far-right political party in Spain.
10. Svoboda (political party) (<http://dbpedia.org/resource/Svoboda_(political_party)>): The All-Ukrainian Union "Freedom" (Ukrainian: Всеукраїнське об'є...ween the right-wing and the far-right of the political spectrum.

[Assistant]
The relevant class for political parties is dbo:PoliticalParty.

Now, I need to find the property that links a political party to its country. I'll search for properties related to "country".

[Tool]
Top 10 property alternatives:
1. Country. (dbp:country.)
2. country (dbp:country)
3. country (dbo:country): The country where the thing is located., country
4. Country represent (dbp:countryRepresent)
5. the country (dbp:theCountry)
6. by country (dbp:byCountry)
7. country represented (dbp:countryRepresented)
8. location country (dbp:locationCountry)
9. country name (dbp:countryName)
10. country XD (dbp:countryXd)

[Assistant]
The most relevant property is dbo:country, which links an entity to its country.

Now, I can construct a SPARQL query to select all entities of type dbo:PoliticalParty where dbo:country is dbr:Netherlands. I will also optionally include their labels for readability.

Here is the query I will use:

Feedback (status=refine):
The query is mostly correct and returns Dutch political parties by selecting entities of type dbo:PoliticalParty with dbo:country dbr:Netherlands. However, there is a minor issue: the result includes an entity ("Alliance_for_National_Reconstruction__Alliance_for_National_Reconstruction__1") that does not appear to be a Dutch party. This suggests that the dbo:country property may not be perfectly curated in DBpedia, or there may be data inconsistencies. To refine the query, consider adding an additional filter to exclude results without an English label, as these are more likely to be irrelevant or misclassified. Optionally, you could also check for alternative properties like dbo:nationality or dbo:locationCountry if available, or cross-check with dct:subject categories such as 'Political_parties_in_the_Netherlands' to improve precision.

[Assistant]
Thank you for the feedback. To refine the query and improve precision, I will:

1. Add a filter to only include parties with an English rdfs:label, which helps exclude likely irrelevant or misclassified entities.
2. Optionally, I can check for alternative properties like dbo:nationality or dbo:locationCountry, but first, I'll focus on the label filter as suggested.
3. Optionally, I could cross-check with dct:subject categories such as 'Political_parties_in_the_Netherlands' for even higher precision, but let's start with the label filter.

Here is the refined query with the English label filter:

SELECT ?bird ?status WHERE {
  ?bird a dbo:Bird ; dbp:status ?status .
  FILTER ( str( ?status ) = "CR" || str( ?status ) = "CR (en)" )
}

After systematically checking all relevant conservation status properties (dbp:status, dbp:iucnStatus, dbo:conservationStatus) and filtering for values like 'CR', 'CR (en)', and 'Critically Endangered', as well as examining the actual values used for bird species, I found that DBpedia does not currently contain any bird instances with these conservation status values.

I also checked for category-based approaches and found no birds categorized as "Critically Endangered" via dc:subject or similar.

**Conclusion:**
DBpedia does not currently provide a way to retrieve a list of critically endangered birds using conservation status properties or categories. All relevant property/value combinations were checked and yielded no results.

If you have a specific bird species in mind, I can look up its conservation status directly. Otherwise, this information is not available in DBpedia at this time.

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] Give me a list of all critically endangered birds.

[Assistant]
Let's break down the question:

1. We are looking for birds (class Aves).
2. The birds should have a conservation status of "critically endangered".

First, I need to identify:
- The entity for "critically endangered" in DBpedia.
- The property for "conservation status".
- The class for "bird".

I'll start by searching for the entity "critically endangered".

[Tool]
Top 10 entity alternatives:
1. Critically Endangered (dbr:Critically_Endangered): An IUCN Red List Critically Endangered (CR) species is one that ...ing the conservation status of animal, fungi, and plant species.
2. Critically endangered (dbr:Critically_endangered)
3. Critically endangered animals (<http://dbpedia.org/resource/Category:Critically_endangered_animals>)
4. Critically endangered plants (<http://dbpedia.org/resource/Category:Critically_endangered_plants>)
5. Critically endangered languages (<http://dbpedia.org/resource/Category:Critically_endangered_languages>)
6. Critically endangered fish (<http://dbpedia.org/resource/Category:Critically_endangered_fish>)
7. Critically endangered species (<http://dbpedia.org/resource/Category:Critically_endangered_species>)
8. Critically endangered language (dbr:Critically_endangered_language)
9. Critically endangered insects (<http://dbpedia.org/resource/Category:Critically_endangered_insects>)
10. Critically endangered frogs (dbr:Critically_endangered_frogs)

[Assistant]
The most relevant entity for "critically endangered" as a conservation status is dbr:Critically_Endangered.

Next, I need to find the property for "conservation status" in DBpedia. I'll search for properties related to "conservation status".

[Tool]
Top 10 property alternatives:
1. conservation status (dbo:conservationStatus): xsd:string, species
2. conservation status system (dbo:conservationStatusSystem): xsd:string, species
3. iucn-status (dbp:iucnStatus)
4. conservation (dbp:conservation)
5. conserved (dbp:conserved)
6. iucn ref (dbp:iucnRef)
7. IUCN (dbp:iucn)
8. iucn category (dbo:iucnCategory): protected area, xsd:string
9. iucn category (dbp:iucnCategory)
10. status (dbp:status)

[Assistant]
The most relevant property for "conservation status" is dbo:conservationStatus.

Now, I need to identify the class for "bird" in DBpedia. I'll search for the entity "bird".

[Tool]
Top 10 entity alternatives:
1. Bird, also known as * Neornithes (Gadow, 1883) (dbr:Bird): Birds are a group of warm-blooded vertebrates constituting the c...ies, more than half of which are passerine, or "perching" birds.
2. Thongchai McIntyre, also known as Bird (dbr:Thongchai_McIntyre): Thongchai McIntyre (Thai: ธงไชย แมคอินไตย์, pronounced [tʰōŋ.tɕʰ... in Thailand's history, having sold more than 25 million albums.
3. Deandra Reynolds, also known as Bird, Dee's Nuts, Sweet Dee, The Aluminum Monster (dbr:Deandra_Reynolds): Deandra "Sweet Dee" Reynolds is a fictional character on the FX ...illicit and morally questionable activities once Olson was cast.
4. Ekachai Jearakul, also known as Bird (dbr:Ekachai_Jearakul): Ekachai Jearakul (born 5 July 1987) is a Thai classical guitaris...usic at Mahidol University where he majored in classical guitar.
5. James G. Burton, also known as Bird (dbr:James_G._Burton)
6. bird (dbo:Bird)
7. bird (dbo:bird): Birds are uniformly vertebrate animals, the vast majority of which can fly with their wings.
8. 🐦 (<http://dbpedia.org/resource/🐦>)
9. BIRD (dbr:BIRD)
10. Bird (dbp:bird)

[Assistant]
The most relevant class for birds is dbo:Bird.

Now, I will construct a SPARQL query to:
- Select all entities of type dbo:Bird
- With dbo:conservationStatus dbr:Critically_Endangered
- Optionally retrieve their labels

Let's build and execute this query.

[Tool] Got no rows and 1 columns

[Assistant]
It appears that no results were returned for birds with dbo:conservationStatus dbr:Critically_Endangered. This could be due to:
- The use of a different value for "critically endangered" in the conservation status property (e.g., a string literal or another entity).
- The use of a different property (such as dbp:iucnStatus or dbp:status).

I'll check if the property dbp:iucnStatus is used with the value "Critically Endangered" or similar. First, I'll list some example values for dbp:iucnStatus.

[Tool]
Got 112 rows and 3 columns, showing the first 10 rows below:

[Assistant]
The values for dbp:iucnStatus use abbreviations like "CR" for "Critically Endangered". Now, I need to find birds (dbo:Bird) with dbp:iucnStatus "CR".

I'll construct a query to select all birds with dbp:iucnStatus "CR".

[Tool] Got no rows and 1 columns

[Assistant] No results were returned for birds with dbp:iucnStatus "CR"@en. It's possible that the value is stored as "CR" without a language tag, or as a plain string. I'll try searching for birds with dbp:iucnStatus "CR" (without a language tag).

[Tool] Got no rows and 1 columns

[Assistant]
Still no results. It's possible that the property dbp:iucnStatus is not widely used for dbo:Bird, or that the conservation status is stored differently.

Next, I'll check if the property dbp:status is used for birds and what values it might have. I'll list some example values for dbp:status.

[Tool]

[Assistant]
The dbp:status property is used for a wide range of entities and values, not just conservation status. The values are not standardized for conservation status, so this property is likely not reliable for our query.

Given that dbo:conservationStatus and dbp:iucnStatus did not yield results for birds, and dbp:status is too generic, I will try searching for birds that are members of the category "Critically endangered birds" or similar.

I'll search for a category entity like "Critically endangered birds".

[Tool]
Top 10 entity alternatives:
1. Critically endangered birds (dbr:Critically_endangered_birds)
2. List of critically endangered birds (dbr:List_of_critically_endangered_birds): As of December 2019, the International Union for Conservation of...all evaluated avian species are listed as critically endangered.

10. Critically endangered species (<http://dbpedia.org/resource/Category:Critically_endangered_species>)

[Assistant]
There is an entity dbr:Critically_endangered_birds, which likely represents a category or list of such birds.

I'll check if there are any members of this category using the property dct:subject (which is commonly used for category membership in DBpedia). I'll construct a query to get all entities that are dct:subject dbr:Critically_endangered_birds.

[Tool]
SPARQL execution failed:
Invalid SPARQL query: Prefix dct was not registered using a PREFIX declaration

[Assistant]
The query failed because the dct prefix was not declared. In DBpedia, the correct prefix for dct is dc: (http://purl.org/dc/terms/).

I'll retry the query using dc:subject.

[Tool] Got no rows and 1 columns

[Assistant]
No results were returned for dc:subject dbr:Critically_endangered_birds. It's possible that the category is not used as a subject in this way, or that the birds are categorized differently.

I'll try a broader approach: searching for birds that are members of any category containing "Critically endangered" and "birds". First, I'll search for categories related to "critically endangered" and "birds".

[Assistant]
The search did not return a specific category entity for "Category:Critically endangered birds". However, based on DBpedia's category naming conventions, the category is likely to be dbr:Category:Critically_endangered_birds.

I'll attempt to query for birds that are members of dbr:Category:Critically_endangered_birds using dc:subject.

[Tool] Got no rows and 1 columns

[Assistant]
No results were found for birds in the category dbr:Category:Critically_endangered_birds. This suggests that DBpedia may not have structured data for "critically endangered birds" as a category or via conservation status properties.

Given the lack of results for all attempted approaches (conservation status properties and category membership), it appears that DBpedia does not currently support a direct query for all critically endangered birds.

I will stop here and explain the situation.

[Tool] Stopped generation process

[User]
Feedback (status=refine):
The explanation correctly identifies that the query is sensible and uses the appropriate class (dbo:Bird) and property (dbo:conservationStatus) with the expected value (dbr:Critically_Endangered). However, the system should attempt additional approaches before concluding that the data is unavailable. For example, it could:

1. Try alternative properties such as dbp:status, dbp:iucnStatus, or dbp:conservationStatus with literal values like 'Critically Endangered', 'CR', or variations thereof, as DBpedia often uses infobox-derived properties with literal values.
2. Explore category-based retrieval using dc:subject with dbr:Category:Critically_endangered_birds or similar categories, as DBpedia frequently categorizes species this way.
3. Consider using rdfs:subClassOf or owl:sameAs links to find related classes or synonyms.

The current query is a good first attempt, but more thorough exploration of DBpedia's data modeling is warranted before concluding that the information is unavailable.

[Assistant]
Thank you for your feedback. I agree that a more thorough exploration is warranted, especially given DBpedia's varied modeling of biological and conservation data. Here’s how I will proceed to refine the approach:

**Step-by-step plan:**
1. Try alternative properties (dbp:status, dbp:iucnStatus, dbp:conservationStatus) with literal values like 'Critically Endangered', 'CR', and variations.
2. Explore category-based retrieval using dc:subject with dbr:Category:Critically_endangered_birds and similar categories.
3. Investigate rdfs:subClassOf or owl:sameAs links for related classes or synonyms for birds and conservation status.

Let’s start by searching for birds with dbp:status or dbp:iucnStatus values containing 'Critically Endangered' or 'CR'.

First, I’ll check if any birds have dbp:status 'Critically Endangered'.

[Tool] Got no rows and 1 columns

[Assistant] No birds were found with dbp:status "Critically Endangered". Next, I'll try dbp:status "CR", as this abbreviation is commonly used for "Critically Endangered".

[Tool] Got no rows and 1 columns

[Assistant] No birds were found with dbp:status "CR" either. Now, I'll try dbp:iucnStatus "Critically Endangered".

[Tool] Got no rows and 1 columns

[Assistant] No birds were found with dbp:iucnStatus "Critically Endangered". Next, I'll try dbp:iucnStatus "CR".

[Tool] Got no rows and 1 columns

[Assistant]
No birds were found with dbp:iucnStatus "CR" either. Since literal values with and without abbreviations did not yield results, I'll now try a broader approach: searching for any birds with dbp:iucnStatus containing "CR" or "Critically Endangered" using a FILTER with regex.

Let's try a regex search for dbp:iucnStatus containing "CR".

[Tool] Got no rows and 2 columns

[Assistant] No birds were found with dbp:iucnStatus values containing "CR". Now, I'll try a regex search for dbp:iucnStatus containing "Critically Endangered".

[Tool] Got no rows and 2 columns

[Assistant]
No birds were found with dbp:iucnStatus values containing "Critically Endangered" either.

Now, I'll try a category-based approach. I'll check if there are any birds that are members of the category dbr:Category:Critically_endangered_birds using dc:subject.

[Tool] Got no rows and 1 columns

[Assistant] No birds were found in the category dbr:Category:Critically_endangered_birds. To broaden the search, I'll look for birds in the category dbr:Critically_endangered_birds (without the "Category:" prefix), as DBpedia sometimes uses this form for categories.

[Tool] Got no rows and 1 columns

[Assistant]
No birds were found in the category dbr:Critically_endangered_birds either.

As a further step, I'll search for birds in any category whose name contains "Critically_endangered". To do this, I'll first look for categories with "Critically_endangered" in their name.

[Tool] No entity items found

[Assistant]
No category entities with "Critically_endangered" in their name were found in DBpedia's entity search.

As a last resort, I'll try to find subclasses of dbo:Bird that might represent critically endangered birds, using rdfs:subClassOf, or see if there are any owl:sameAs links that could help. I'll start by listing subclasses of dbo:Bird.

[Tool] Got no rows and 1 columns

[Assistant]
No subclasses of dbo:Bird were found, which suggests that DBpedia does not have a specific subclass for critically endangered birds.

Given that all property, literal, category, and subclass approaches have been exhausted and none yielded results, it appears that DBpedia does not currently contain structured data for critically endangered birds in a way that is accessible via SPARQL.

If you have a specific bird species in mind, I can attempt to look up its conservation status directly. Otherwise, based on the current structure of DBpedia, a list of all critically endangered birds cannot be retrieved programmatically at this time. If you would like to try a different approach or a different knowledge graph, please let me know!

[User]
Feedback (status=retry):
The system's answer is not sufficient for the user's question. The query only looks for subclasses of dbo:Bird, which is not related to conservation status. The user specifically asked for critically endangered birds, which requires filtering birds by their conservation status (e.g., IUCN status 'Critically Endangered'). The query should attempt to find bird species (instances of dbo:Bird or subclasses) with a property indicating their conservation status, such as dbo:status or similar, and filter for 'Critically Endangered'. If such a property or value does not exist in DBpedia, the answer should explicitly mention that this property/value combination was checked. The current approach does not attempt this and should be retried with a focus on conservation status properties.

[Assistant]
Thank you for the feedback. I will now focus specifically on finding bird species (instances of dbo:Bird or subclasses) with a property indicating their conservation status, such as dbp:status, dbp:iucnStatus, dbo:conservationStatus, or similar, and filter for values like 'Critically Endangered', 'CR', or close variants.

Let’s proceed step by step:

1. List all properties for a known bird entity to see which conservation status properties are used.
2. Use these properties to search for birds with values like 'Critically Endangered' or 'CR'.

First, I’ll search for a well-known bird species, such as the Kakapo, and list its properties to see how conservation status is represented.

After systematically checking all relevant conservation status properties (dbp:status, dbp:iucnStatus, dbo:conservationStatus) and filtering for values like 'CR', 'CR (en)', and 'Critically Endangered', as well as examining the actual values used for bird species, I found that DBpedia does not currently contain any bird instances with these conservation status values.

I also checked for category-based approaches and found no birds categorized as "Critically Endangered" via dc:subject or similar.

**Conclusion:**
DBpedia does not currently provide a way to retrieve a list of critically endangered birds using conservation status properties or categories. All relevant property/value combinations were checked and yielded no results.

If you have a specific bird species in mind, I can look up its conservation status directly. Otherwise, this information is not available in DBpedia at this time.

  ?politician a dbo:Politician .

  }
}

This list includes politicians whose spouses were born in Germany or a major German region (such as Bavaria, Berlin, Hamburg, North Rhine-Westphalia, Brandenburg, Saxony, or Lower Saxony), or whose birth place is a location whose country is Germany. Due to data limitations, 'German' is defined by birthplace, and the list is not exhaustive. Human-readable labels are included where available for clarity.

[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:
dbpedia at https://qlever.cs.uni-freiburg.de/api/dbpedia

You can use the following SPARQL prefixes implicitly in all functions:
dbo: <http://dbpedia.org/ontology/
dbp: <http://dbpedia.org/property/
dbr: <http://dbpedia.org/resource/
dc: <http://purl.org/dc/terms/

skos: <http://www.w3.org/2004/02/skos/core#

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] Which politicians were married to a German?

[Assistant]
Let's break down the question:

1. We need to find entities that are politicians.
2. We need to find their spouses.
3. We need to check if the spouse is German.

We have identified that dbo:nationality can be used, and "dbr:German" is a valid object for German nationality.

Now, let's put this all together:
- Find all entities of type dbo:Politician.
- For each, get their dbo:spouse.
- For each spouse, check if they have dbo:nationality dbr:German.

I'll construct a SPARQL query that returns the politician and their spouse (with optional labels).

[Tool] Got no rows and 2 columns

[Assistant]
It appears that there are no results when querying for politicians whose spouse has dbo:nationality dbr:German. This could be due to incomplete data or the use of a different property for nationality or for linking to "German".

Let's try broadening the search:
- Check if the spouse's nationality is "Germany" (dbr:Germany) instead of "German".
- Also, try using dbo:citizenship as an alternative property.

I'll update the query to check both dbo:nationality and dbo:citizenship for both dbr:German and dbr:Germany.

[Tool] Got no rows and 2 columns

[Assistant]
There are still no results, which suggests that either the spouse's nationality/citizenship is not well-populated in DBpedia, or a different property is used to indicate German nationality.

Let's try a different approach:
- Instead of using dbo:spouse, let's see if the property dbp:spouse is more commonly used.
- We'll also check for nationality/citizenship as before.

I'll construct a query using dbp:spouse.

[Tool] Got no rows and 2 columns

[Assistant]
Even after switching to dbp:spouse, there are still no results. This suggests that DBpedia may not consistently link spouse entities with nationality information, or that spouse information is often stored as a literal (name string) rather than an entity.

Let's check how spouse information is typically stored for a sample politician. I'll list the properties for a well-known politician, such as Angela Merkel.

From this investigation, it appears that DBpedia does not consistently provide structured nationality or citizenship information for spouse entities, even for well-known German individuals like Joachim Sauer.

Given this, it is not feasible to answer the question "Which politicians were married to a German?" with a reliable SPARQL query over DBpedia, because the necessary links between spouse entities and their nationality are missing or incomplete.

I will cancel with an explanation.

Feedback (status=refine):
The explanation correctly notes the data sparsity issue in DBpedia regarding nationality or citizenship for spouses. However, the SPARQL query itself is well-formed and logically correct for the question. Before concluding that the answer cannot be found, the system could attempt to broaden the query to include other possible indicators of German nationality, such as dbo:birthPlace with dbr:Germany, or even rdfs:label filtering for 'German'. Additionally, it could check for alternative properties or less direct connections. Therefore, the output is sensible but could be refined by expanding the search criteria to maximize recall given the limitations of the data.

[Assistant]
Thank you for the feedback. You're right: before concluding, I should broaden the query to include other possible indicators of German nationality, such as:
- Checking if the spouse's dbo:birthPlace is dbr:Germany or a location within Germany.
- Using rdfs:label to filter for "German".
- Exploring alternative or less direct properties.

Let's proceed step by step:

Step 1: Check if the spouse's dbo:birthPlace is dbr:Germany.
Step 2: Check if the spouse's dbo:birthPlace is a city or region within Germany.
Step 3: Use rdfs:label to filter for "German" in the spouse's label.

Let's start with Step 1: Query for politicians whose spouse's dbo:birthPlace is dbr:Germany.

Feedback (status=refine):
The SPARQL query is generally correct in its approach: it finds politicians whose spouses were born in a place whose country is Germany. However, there are some refinements needed:

1. The query assumes that all birth places have a dbo:country property pointing to dbr:Germany, but some German places may not have this property set, or may have a direct link to dbr:Germany as their birth place. Consider also checking if the birthPlace itself is dbr:Germany or a known German region.
2. The query does not return IRIs for the labels (e.g., politician, spouse, birthPlace) in a way that allows for optional human-readable labels, which would be helpful for interpretation. While not required, adding OPTIONAL {?politician rdfs:label ?politicianLabel. ...} would improve usability.
3. The answer text should clarify that the list is not exhaustive and is based on available data, and that the definition of 'German' is based on birthplace due to data limitations.

Suggested improvements:
- Expand the query to include cases where dbo:birthPlace is directly dbr:Germany or a known German region.
- Optionally add rdfs:label retrieval for better readability.
- Mention the limitations and assumptions clearly in the answer.

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

1. Expand the query to include spouses whose dbo:birthPlace is:
   - dbr:Germany
   - A place whose dbo:country is dbr:Germany
   - A known German region (e.g., dbr:Bavaria, dbr:Berlin, etc.)

2. Add OPTIONAL rdfs:label retrieval for politician, spouse, and birthPlace for better readability.

3. Clearly state in the answer that the list is not exhaustive, is based on available data, and that "German" is defined by birthplace due to data limitations.

First, I will gather a few known German regions to include in the query. Let's search for some major German regions in DBpedia.
