We describe the use of energy function op- timisation in very shallow syntactic pars- ing. The approach can use linguistic rules and corpus-based statistics, so the strengths of both linguistic and statisti- cal approaches to NLP can be combined in a single framework. The rules are con- textual constraints for resolving syntactic ambiguities expressed as alternative tags, and the statistical language model consists of corpus-based n-grams of syntactic tags. The success of the hybrid syntactic dis- ambiguator is evaluated against a held-out benchmark corpus. Also the contributions of the linguistic and statistical language models to the hybrid model are estimated.
