| With the popularization of computer and the sharing of network resources,mankind has entered the information age.We use a computer as the most basic tool,no matter what type of data is being processed.Similarly,in the field of information processing,the Tibetan information processing also shifts from the original word processing to the natural language research and processing level.In this process,however,all information processing techniques are studied and processed at the wordbased level.The word is divided into a real term and a noun phrase.In which a noun phrase is attached to an actual word or sentence representing a grammatical meaning.They cannot be used alone as syntactic components and cannot play different roles in different contexts The character,and it’s ambiguous.Which greatly reduces the accuracy of the Tibetan automatic word segmentation in the field of the Tibetan information processing.In the face of the machine,the ambiguity of the noun phrases in the field of information processing has a great negative impact on the sentence generation,the sentence understanding and the semantic understanding.Therefore,it is one of the important contents to be solved in the information processing,and it is the most important part in the study of Tibetan grammar.On the basis of the traditional Tibetan grammar rules,dissertation designs a Tibetan tree segmentation algorithm and a Tibetan noun phrase automatic recognition algorithm which accord with the Tibetan characteristics.The definition and elimination of the ambiguity of the noun phrases in the Tibetan language in the sentence are identified and eliminated by the establishment of the Tibetan-language noun phrase disambiguation rule base.In that end,the automatic identification system of the term phrase of the Tibetan language is realize,so that the computer can eliminate the ambiguous noun phrase in the Tibetan language sentence,quickly identify the term of the Tibetan language,and improve the accuracy of the automatic word segmentation of the Tibetan language,thereby accurately generating the syntactic analysis sentence.It lays a foundation for the research of 8-frame recognition and machine translation. |
