Multilingual Annotation of a Shallow Ontology of Entities, Events, and Relations

This paper describes an effort to annotate entities, events, and relations in multilingual news stories. We iteratively refined a flat and shallow ontology to achieve fast and consistent annotations that capture more of the essence of news stories than previous work. Initial results obtained by training automatic extractors with the annotated data are promising. We present these results and discuss the challenges we faced.
