Automatic translation for Vietnamese based on UNL language

In the field of Natural Language Processing, Universal Networking Language (UNL) has been used by various researchers as an interlingual approach for automated machine translation. The UNL system consists of two main components, namely, EnConverter used for converting the text from a source language to UNL and DeConverter used for converting from UNL to a target language. Currently, many projects are researching to apply UNL in different languages except Vietnamese. In this paper, we introduce the tools that are UNL's applications and how to reuse it's for the process of encoding a Vietnamese sentence into UNL expression and decoding an UNL expression into Vietnamese. The testing tools, we is done with about 1,000 Vietnamese sentence (with the help of about 4573 dictionary entries and 3161 rules) to compare the proportion of sentences was changed between the direct method and translation through intermediate language UNL.
