Event Linking: Grounding Event Reference in a News Archive.

Interpreting news requires identifying its constituent events. Events are complex linguistically and ontologically, so disambiguating their reference is challenging. We introduce event linking , which canonically labels an event reference with the article where it was first reported. This implicitly relaxes coreference to co-reporting , and will practically enable augmenting news archives with semantic hyperlinks. We annotate and analyse a corpus of 150 documents, extracting 501 links to a news archive with reasonable inter-annotator agreement.
