Drawing on a Chinese-English parallel corpus, the system performs word segmentation for Chinese input sentence and employs TF * IDf (term frequency * inverse document frequency) for calculating the weighting of each word. Using term weighting and a Chinese thesaurus for query expansion, the system is capable of retrieving and ranking synonymous or conceptually similar Chinese sentences along with their English translations. |
