In this research, we would like to build an initial model for semantic parsing of simple Vietnamese sentences. With a semantic parsing model like that, we can analyse simple Vietnamese sentences to determine their semantic structures that are represented in a form that was defined by our point of view. So, we try to solve two tasks: first, building an our taxonomy of Vietnamese nouns, then we use it to define the feature structures of nouns and verbs; second, to build a Unification-Based Vietnamese Grammar we
define the syntactic and semantic unification rules for the Vietnamese phrases, clauses and sentences based on the Unification-Based Grammar. This Vietnamese grammar has been used to build a semantic parser for single Vietnamese sentences. This semantic parser has been experienced and the experiment results get precision and recall all over 84%.

As an extension of decades of syntactic theorizing, treebanks have inherited a small set of phrasal categories, which abstract over the environments that the categories can occur in. Extending ideas from Johnson (1998), we explore encoding information from the local tree context in each category. We then discuss two clustering techniques which preserve the distributionally relevant category distinction, forming linguistically relevant generalizations and improving PCFG parsing performance.
