How collect Wikidata's entities by a certain property?

8

Assuming you are familiar with SPARQL, Wikidata (not to be confused with DBpedia) has an official endpoint and a page with example queries. The following example lists all countries with the property sovereign state:

PREFIX wikibase: <http://wikiba.se/ontology#>
PREFIX wd: <http://www.wikidata.org/entity/>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>

SELECT ?cid ?country WHERE {
    ?cid wdt:P31 wd:Q3624078 .
    OPTIONAL {
        ?cid rdfs:label ?country filter (lang(?country) = "en") .
    }
}

For more information, please visit official reference for data access.

While not the most script-friendly, here is the easiest/fastest way to get what you want without any third-party:

1) Go to the Wikidata page of the property

2) Click What links here in the left panel's Tools section:

Wikidata property: What links here

3) Enjoy the paged list:

Wikidata list

You can do it by using MediaWiki API for Wikidata with backlinks query

https://www.wikidata.org/w/api.php?action=query&list=backlinks&blnamespace=0&bllimit=500&&bltitle=Property:P1086

In above example blnamespace=0 means the result list to include only items (without user pages, talk pages, templates, etc.). The example is for atomic number (P1086) property.

Depending on what property you are looking for (the question isn't that clear) you could use DBpedia and SPARQL any entities that have a connection with a certain link/property.
