Abstract: Lexicon is an important resource in natural language processing (NLP), as it provides NLP systems with lexical information at different levels, from morphology to semantics. For Vietnamese, lexical resources are available for several basic tools such as word segmentation, part-of-speech tagging and syntactic parsing. In this paper, we discuss the construction of a lexicon enriched with syntactic and semantic information, based on an existing computational lexicon for Vietnamese. This lexicon is designed to serve for a syntactic and semantic parser using the tree adjoining grammar (TAG) formalism.
