Towards a complete event type taxonomy

We present initial results of our effort to build an extensive and complete taxonomy of events described in news articles. By crawling Wikipedia's current events portal we identified nine top-level event types. Using articles referenced by the portal we built a event type classification model for news articles using lexical and semantic features and present a small-scale manual evaluation of its results. Results show that our model can accurately distinguish between event types but its coverage could still be significantly improved.
