Semantic Parsing of Simple Sentences in Unification-Based Vietnamese Grammar
Dang Tuan Nguyen, Khoa Dang Nguyen, Ha Thanh Le · International Journal on Natural Language Computing · 2013
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%.
