Tibetan Verb Recognition And Feature Analysis For Natural Language Processing

Natural language processing studies language problems of human-to-human communication and human-to-computer communication,including language represent ability,language application model,computational framework construction for building language models,designing and realize practical systems based on the language model and computational framework,discussing the practical systems evaluation technologies.Its main research interests include lexical analysis,syntactic analysis,semantic analysis and pragmatic analysis.Verbs play a vital role in language,and the research of it plays an extremely important role in the processing of language information.The recognition and features analysis of Tibetan verbs is a basic work of Tibetan natural language processing.Based on the study of Chinese and English verbs,this paper analyzes and combines traditional Tibetan grammar to study Tibetan verbs' identification and characteristics oriented to natural language processing,the main work includes:1.Establishing Tibetan verb dictionaries setThe dictionaries set is a collection of word materials and plays an important role in natural language processing.Based on the characteristics of Tibetan and the analysis of existing Tibetan dictionary,this paper designs the structure of Tibetan dictionaries set,establishes a Tibetan verb dictionaries set for Tibetan verb recognition and feature analysis.2.Recognition of Tibetan verbsTibetan verb recognition is the basis for analyzing its characteristics,it is also one of the key techniques for Tibetan syntactic analysis and semantic analysis.Based on the established Tibetan verb dictionary,this paper combines dictionary matching and statistics to identify Tibetan verbs,and verifies the effectiveness of the method.3.Analysis of the characteristics of Tibetan verbsTibetan verbs are a very important word class,the features analysis of them plays an important role in syntactic analysis,semantic analysis and pragmatic analysis of Tibetan texts.This paper studies the characteristics of Tibetan verbs from four aspects:distribution characteristics,constitutive features,combination features and grammatical features,and obtains some valuable conclusions.
