Dynamic Bayesian networks (DBNs) offer an elegant way to integrate various
aspects of language in one model. Many existing algorithms developed for
learning and inference in DBNs are applicable to probabilistic language
modeling. To demonstrate the potential of DBNs for natural language processing,
we employ a DBN in an information extraction task. We show how to assemble
wealth of emerging linguistic instruments for shallow parsing, syntactic and
semantic tagging, morphological decomposition, named entity recognition etc. in
order to incrementally build a robust information extraction system. Our method
outperforms previously published results on an established benchmark domain.Comment: 6 page
