Abstract：Tibetan functional chunks describe a sentence skeleton, and they are the link between sentence structure and semantics. In this paper, we proposed primary functional chunks in Tibetan and a functional chunk tag system. Based on the theory, a functional chunk boundary detection algorithm was proposed. Experiments on a limited scale data suggest that the algorithm is capable of recognizing most boundaries and deserves to be studied deeply. Key wordsTibetan functional chunks; chunks boundary detection; CRFs
