Abstract：This paper presents a Chinese-Tibetan base noun phrase alignment method. Its a two-phase procedureChinese base noun phrases identification and finding their Tibetan correspondences. We propose head-phrase extension based Tibetan base noun phrase identification method in accordance with the morphologic characteristics of Tibetan. In the first phase, we use sequence intersection operation to get Tibetan head-phrase. In the second phase, head-phrase extension confidence is defined and applied to determine the boundary of correspondence. Experimental result indicates that sequence intersection outperforms other methods in head-phrase extension. Chinese-Tibetan base noun phrase produced by our method is effective in reducing subsequent manual check, facilitating the construction of translation lexicon on phrase level.
