Wikidata: A Free Collaborative Knowledge Base by Denny Vrandečić and Markus Krötzsch.
Abstract:
Unnoticed by most of its readers, Wikipedia is currently undergoing dramatic changes, as its sister project Wikidata introduces a new multilingual ‘Wikipedia for data’ to manage the factual information of the popular online encyclopedia. With Wikipedia’s data becoming cleaned and integrated in a single location, opportunities arise for many new applications.
In this article, we provide an extended overview of Wikidata, including its essential design choices and data model. Based on up-to-date statistics, we discuss the project’s development so far and outline interesting application areas for this new resource.
