To construct the bilingual parallel corpus,the alignment at sentence level is a basic task.Considering the specific characteristic of Tibetan language,this paper proposes a dictionary-based Chinese-Tibetan sentence automatic alignment method.It establishes a bilingual dictionary for alignment,and evaluates its word coverage.To address the issueof different granularity between Chinese word segmentation and Tibetan word segmentation,this paper chooseto further look up the remaining big Tibetan word in Tibetan-Chinese dictionary and then match it in the original Chinese sentence,which increases the precision.Experiments show an average precision of 81.11% for this approach.
