Exploiting role-identifying nouns and expressions for information extraction. Phillips, W. & Riloff, E. In Proceedings of International Conference on Recent Advances in Natural Language Processing, pages 165–172, 2007. Citeseer.
Website abstract bibtex We present a new approach for extraction pat- tern learning that exploits role-identifying nouns, which are nouns whose semantics reveal the role that they play in an event (e.g., an “assassin” is a perpetrator). Given a few seed nouns, a boot- strapping algorithm automatically learns role- identifying nouns, which are then used to learn extraction patterns. We also introduce a method to learn role-identifying expressions, which con- sist of a role-identifying verb linked to an event (e.g., “ participated in the murder”). We present experimental results on the MUC-4 terrorism corpus and a disease outbreaks corpus.
