Abstract

Word segmentation is a basic work of natural language processing, which has a great influence on the subsequent work of it. The recognition of abbreviated case-auxiliary words is one of the most difficult and important technologies of Tibetan word segmentation. Through dissecting the existing recognition methods of abbreviated case-auxiliary words, this paper analyzed the characteristics of Tibetan words, pointedly proposed recognition algorithm of Tibetan abbreviated case-auxiliary words rules, add-restore algorithm and the maximum entropy models feature template, then the methods of recognizing abbreviated case-auxiliary words based on the rules, it obtained add-restore methods and the maximum entropy model. The experimental data shows that the accuracy, recall rate and F1 value of the method is 99.26%, 96.47%, and 97.85% respectively, which shows an obvious progress than that of the existing methods.
