Two Layers of Annotation for Representing Event Mentions in News Stories

In this paper, we describe our preliminary study of methods for annotating event mentions as part of our research on highprecision models for event extraction from news. We propose a two-layer annotation scheme, designed to capture the functional and the conceptual aspects of event mentions separately. We hypothesize that the precision can be improved by modeling and extracting the different aspects of news events separately, and then combining the extracted information by leveraging the complementarities of the models. We carry out a preliminary annotation using the proposed scheme and analyze the annotation quality in terms of inter- annotator agreement.
