Identity and Granularity of Events in Text
This work addresses event coreference in text for natural language processing applications, representing an incremental improvement with a focus on semantic modeling.
The paper tackles the problem of detecting and modeling event descriptions in news articles to solve cross-document event coreference, achieving performance close to state-of-the-art methods and outperforming others under similar event detection quality.
In this paper we describe a method to detect event descrip- tions in different news articles and to model the semantics of events and their components using RDF representations. We compare these descriptions to solve a cross-document event coreference task. Our com- ponent approach to event semantics defines identity and granularity of events at different levels. It performs close to state-of-the-art approaches on the cross-document event coreference task, while outperforming other works when assuming similar quality of event detection. We demonstrate how granularity and identity are interconnected and we discuss how se- mantic anomaly could be used to define differences between coreference, subevent and topical relations.
