Information Extraction Patterns

We present a coreference resolver called BABAR that uses contextual role knowledge to evaluate possible antecedents for an anaphor. BABAR uses information extraction patterns to identify contextual roles and creates …...

This paper presents a method of automat- ically constructing information extraction patterns on predicate-argument structures (PASs) obtained by full parsing from a smaller training corpus. Because PASs represent generalized structures …...

This paper presents a novel approach to the semi-supervised learning of Informa- tion Extraction patterns. The method makes use of more complex patterns than previous approaches and determines their similarity …...
