PoS Disambiguation and Partial Parsing Bidirectional Interaction

Abstract

This paper presents Latch; a system for PoS disambiguation and partial parsing that has been developed for Spanish. In this system, chunks can be recognized and can be referred to like ordinary words in the disambiguation process. This way, sentences are simplified so that the disambiguator can operate interpreting a chunk as a word and chunk head information as a word analysis. This interaction of PoS disambiguation and partial parsing reduces the effort needed for writing rules considerably. Furthermore, the methodology we propose improves both efficiency and results.
