Phrase parsing with rule sequence processors: an application to the shared CoNLL task

For several years, chunking has been an integral part of MITRE's approach to information extraction. Our work exploits chunking in two principal ways. First, as part of our extraction system (Alembic) (Aberdeen et al., 1995), the chunker delineates descriptor phrases for entity extraction. Second, as part of our ongoing research in parsing, chunks provide the first level of a stratified approach to syntax - the second level is defined by grammatical relations, much as in the SPARKLE effort (Carroll et al., 1997).
