Tibetan Text Dependency Syntactic Analysis Based on Discriminant
Haixing Zhao · Jisuanji gongcheng · 2013
(Abstract )The existing Tibetan syntax system is complex, which is not conducive to the application of Tibetan natural language processing. So this paper describes an approach based on discriminant for analysis of Tibetan text dependency structure, where perceptron training method is used to training parsing model. And it also proposes a maximum spanning tree with CYK from the bottomup algorithm for decoding. Experimental resu lts show that, the method obtains acceptable score of 81.2 % on manual test set. And it is applicable to Tibetan dependency library and other natural language processing.
