Here's a rewritten version of the SPARQL query that is independent of Blazegraph and Wikidata-specific features:

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>

SELECT ?item ?itemLabel
WHERE {
  ?item rdf:type <http://example.org/ontology/Cat>.
  ?item rdfs:label ?itemLabel.
  
  # Language filter (optional, adjust as needed)
  FILTER(LANG(?itemLabel) = "" || LANG(?itemLabel) = "en")
}

This query has been modified to be more generic and work with standard SPARQL features. Here are the key changes:

Removed Wikidata-specific prefixes and replaced them with standard RDF and RDFS prefixes. Changed the property wdt:P31 (instance of) to a more generic rdf:type. Replaced the Wikidata item wd:Q146 (cat) with a hypothetical URI <http://example.org/ontology/Cat>. Removed the Wikidata-specific SERVICE wikibase:label and instead directly query for the label using rdfs:label. Added an optional FILTER to handle language selection, which you can adjust or remove based on your needs.

To use this query, you'll need to replace <http://example.org/ontology/Cat> with the appropriate URI for the "cat" concept in your ontology. Also, ensure that your data uses rdfs:label for labeling entities. If your ontology uses a different predicate for labels, you'll need to adjust the query accordingly. Would you like me to explain or break down this SPARQL query further?

Second attempt[edit]

I apologize for the confusion. You're right that the previous query wouldn't work on either the Wikidata Query Service or Qlever as is. Let's create a version that should work on both systems while still being as generic as possible. Here's a revised query:

PREFIX wd: <http://www.wikidata.org/entity/>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>

SELECT ?item ?itemLabel
WHERE {
  ?item wdt:P31 wd:Q146.  # Instance of cat
  
  OPTIONAL {
    ?item rdfs:label ?itemLabel.
    FILTER(LANG(?itemLabel) = "en")
  }
}

This query should work on both the Wikidata Query Service and Qlever. Here's what I've done:

Kept the Wikidata-specific prefixes, as both systems understand these. Used the Wikidata property wdt:P31 (instance of) and the Wikidata item wd:Q146 (cat) as in the original query. Made the label retrieval optional and used the standard rdfs:label property, which both systems support. Added a FILTER to select English labels, but made this part of the OPTIONAL block so items without English labels will still be returned.

This query maintains the core functionality of finding all items that are instances of cats, while being more compatible with different SPARQL endpoints that support Wikidata's structure. To make this query work on a completely generic SPARQL endpoint, you would need to:

Replace the Wikidata-specific URIs with those from your ontology. Ensure your data uses rdfs:label for labels, or replace it with the appropriate property for your dataset.

Would you like me to explain any part of this query in more detail?

Here's the rewritten SPARQL query to be Blazegraph independent:

SELECT ?item ?itemLabel
WHERE {
  ?item rdf:type wd:Q146 . # Must be a cat (rdf:type instead of wdt:P31)
  SERVICE wikibase:label { 
      bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". 
  }
}

Verwende den Code mit Vorsicht.

The changes made are:

   Replaced wdt:P31 with rdf:type: Blazegraph might not recognize wdt:P31 as the property for "instance of" while rdf:type is a more standard property.
   Removed bd:serviceParam: Blazegraph doesn't use bd:serviceParam.

Note: While this query should work in Blazegraph, it's important to consult Blazegraph's documentation for any specific service parameter requirements they might have.

second attempt[edit]

There are a couple of things to consider why the rewritten query might not be working on Wikidata Query Service or QLever:

   Missing SERVICE wikibase:label Support: While removing bd:serviceParam was necessary for Blazegraph, some SPARQL engines like QLever might not inherently support the wikibase:label service.  This service is specific to Wikidata's query functionality.

   Alternative for Retrieving Labels: Here's how to modify the query to retrieve labels without relying on the wikibase:label service:

SELECT ?item ?itemLabel
WHERE {
  ?item rdf:type wd:Q146 . # Must be a cat
  ?item rdfs:label ?itemLabel . 
  FILTER (LANG(?itemLabel) = "[AUTO_LANGUAGE]" || LANG(?itemLabel) = "en" )
}

Changes made:

   Replaced SERVICE wikibase:label: We directly query for labels using rdfs:label.
   Added Filter: We filter the results to only include labels in the user's preferred language ([AUTO_LANGUAGE]) or English (en).

Testing the Query:

You can try this modified query on both Wikidata Query Service (https://query.wikidata.org/) and QLever to see if it retrieves cat names.

Additional Tips:

   Check the documentation for both Wikidata Query Service and QLever for supported SPARQL features and service calls.
   If you encounter further issues, consider sharing the specific error messages you're receiving. This can help in diagnosing the problem more precisely.

Pi AI[edit]

To make the provided SPARQL query Blazegraph-independent, you can remove the Blazegraph-specific service parameter (bd:serviceParam) and use the more generic SERVICE wikibase:label block without specifying the service parameter. The modified query will still retrieve the labels in the user's language or fall back to English if the label is not available in the user's language. Here's the updated query:

# "Cats" example SPARQL query
# https://www.wikidata.org
# /wiki/Wikidata:SPARQL_query_service/queries/examples#Cats
SELECT ?item ?itemLabel
WHERE
{
  ?item wdt:P31 wd:Q146. # Must be a cat
  SERVICE wikibase:label {
      # Automatically selects the user's language or falls back to English
  }
}

This revised query should work with any SPARQL endpoint that supports the SERVICE wikibase:label block without relying on Blazegraph-specific features.

second attempt[edit]

Apologies for any confusion. The previous suggestion assumed that the endpoint used would implicitly support language settings. However, to ensure compatibility with both Wikidata Query Service and QLeVer, you should explicitly specify the language settings. Here's the revised query that should work on both platforms:

# "Cats" example SPARQL query
# https://www.wikidata.org
# /wiki/Wikidata:SPARQL_query_service/queries/examples#Cats
SELECT ?item ?itemLabel
WHERE
{
  ?item wdt:P31 wd:Q146. # Must be a cat
  SERVICE wikibase:label {
      # Specify language settings
      bd:serviceParam wikibase:language "en". 
  }
}

In this query, the bd:serviceParam wikibase:language "en" specifies English as the language for the labels. You can change "en" to any other language code if needed. Please note that QLeVer may require the PREFIX bd: <http://www.bigdata.com/rdf#> directive at the beginning of the query to recognize the bd:serviceParam property. If you're using QLeVer and encounter issues, please add this prefix directive to the query.
