Is it possible to search for properties?

[marcelomachado]

Let's say I would like to perform a lookup search to find the property areaTotal (https://dbpedia.org/ontology/areaTotal), is there any way to use this tool with this purpose?

[JJ-Author]

sure.
this is a very simple example config that indexes everything that has a German label from the dbpedia ontology.

but you can also build more advance keyword-based term searches with lookup
see a prototype here http://tools.dbpedia.org:8765/

but there is also a new project (still experimental) that uses a semantic search with vector embeddings
https://github.com/dbpedia/archivo-term-search-POTS independent of lookup instead using weaviate

the keyword prototype uses the following fields and that would allow e.g. to filter for Object or Datatypeproperties on the field type (not realized by the UI but would be possible with the lookup API)

     - fieldName: label
      resourceName: term
      query: >
        SELECT DISTINCT ?term ?label  WHERE {
          ?term <http://www.w3.org/2000/01/rdf-schema#label> | <http://www.w3.org/2004/02/skos/core#prefLabel> | <http://purl.org/dc/elements/1.1/title> | <http://purl.org/dc/terms/title> ?label .
          FILTER (lang(?label)="en" || lang(?label)="de" || lang(?label)="")
        }
    - fieldName: definition
      resourceName: term
      query: >
        SELECT DISTINCT ?term ?definition WHERE {
          ?term <http://purl.obolibrary.org/obo/IAO_0000115> ?definition .
        }
    - fieldName: type
      resourceName: term
      query: >
        SELECT DISTINCT ?term ?type WHERE {
          ?term <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> ?type .
        }
      fieldType: string
    - fieldName: comment
      resourceName: term
      query: >
        SELECT DISTINCT ?term ?comment WHERE {
          ?term <http://www.w3.org/2000/01/rdf-schema#comment> ?comment .
        }
    - fieldName: altLabel
      resourceName: term
      query: >
        SELECT DISTINCT ?term ?altLabel WHERE {
          ?term <http://www.w3.org/2004/02/skos/core#altLabel> | <http://purl.obolibrary.org/obo/IAO_0000118> ?altLabel .
        }
    - fieldName: description
      resourceName: term
      query: >
        SELECT DISTINCT ?term ?description
        WHERE {
          ?term <http://purl.org/dc/elements/1.1/description> | <http://purl.org/dc/terms/description> | <http://purl.org/dc/terms/abstract> ?description .
        }

and the following search

- fieldName: label
      weight: 8.0
      highlight: true
      queryByDefault: true
    - fieldName: altLabel
      weight: 6.0
      highlight: true
      queryByDefault: true
    - fieldName: definition
      weight: 1.0
      highlight: true
      queryByDefault: true
    - fieldName: description
      weight: 0.9
      highlight: true
      queryByDefault: true
    - fieldName: comment
      weight: 0.8
      highlight: true
      queryByDefault: true
    - fieldName: type
      weight: 20
      highlight: false
      queryByDefault: false
      exact: true
      tokenize: false

@marcelomachado did this help?

@JJ-Author Thank you for your answer!

I was actually thinking in using the open DBpedia Lookup API (https://lookup.dbpedia.org/). Therefore, my question was about the possibility of doing this kind of search using the API. I was wondering something like a uri parameter.
