This paper presents the Event and Implied Situation Ontology (ESO), a manually constructed resource which formalizes the pre and post
situations of events and the roles of the entities affected by an event. The ontology is built on top of existing resources such as WordNet,
SUMO and FrameNet. The ontology is injected to the Predicate Matrix, a resource that integrates predicate and role information from
amongst others FrameNet, VerbNet, PropBank, NomBank and WordNet. We illustrate how these resources are used on large document
collections to detect information that otherwise would have remained implicit. The ontology is evaluated on two aspects: recall and
precision based on a manually annotated corpus and secondly, on the quality of the knowledge inferred by the situation assertions in
the ontology. Evaluation results on the quality of the system show that 50% of the events typed and enriched with ESO assertions are
correct. |
