We argue for the need for the community to address the issue of “dark entities”, those domain entities for which a knowledge base has no information in the context of the entity linking task for building Event-Centric Knowledge Graphs. Through an analysis of a large (1,2 million article) automotive newswire corpus against DBpedia, we identify six classes of errors that lead to dark entities. Finally, we outline further steps that can be taken for tackling this issue.

Abstract
We argue for the need for the community to address the issue of “dark entities”, those domain entities for which a knowledge base has no information in the context of the entity linking task for building Event-Centric Knowledge Graphs. Through an analysis of a large (1,2 million article) automotive newswire corpus against DBpedia, we identify six classes of errors that lead to dark entities. Finally, we outline further steps that can be taken for tackling this issue.File in questo prodotto:
