Translation Selection by Combining Multiple Measures for Sense Disambiguation and Word Selection

2003 International Journal of Computer Processing Of Languages  
Based on the 'word-to-sense and sense-to-word' relationship between a source word and its translations, our method selects translation through two levels: sense disambiguation of a source word and selection  ...  The first one is based on knowledge from a bilingual dictionary, and the others are calculated using statistics from a target language corpus.  ...  Our method that combines sense disambiguation and word selection with multiple measures is open to import any method and any knowledge for sense disambiguation and word selection.  ...
