Code Book for the Annotation of Diverse Cross-Document Coreference of
  Entities in News Articles
Jakob Vogel
This paper presents a scheme for annotating coreference across news articles,
extending beyond traditional identity relations by also considering
near-identity and bridging relations. It includes a precise description of how
to set up Inception, a respective annotation tool, how to annotate entities in
news articles, connect them with diverse coreferential relations, and link them
across documents to Wikidata's global knowledge graph. This multi-layered
annotation approach is discussed in the context of the problem of media bias.
Our main contribution lies in providing a methodology for creating a diverse
cross-document coreference corpus which can be applied to the analysis of media
bias by word-choice and labelling.
