Dictionaries for English-Vietnamese Machine Translation

摘要

Dictionary has an important role in Rule-Based Machine Translation. Many efforts have been concentrated on building machine-readable dictionaries. However, researchers have a long debate about structure and entry of these dictionaries. We develop a syntactic-semantic structure for English-Vietnamese dictionary as first measure to solve lexical gap problem, then use extend feature to improve Vietnamese dictionary to get grammatical target sentences. This work describes dictionaries used in English-Vietnamese Machine Translation (EVMT) at Ho Chi Minh City University of technology. There are three dictionaries: The English dictionary, the bilingual English-Vietnamese and the Vietnamese dictionary.
