Abstract

It is well-known that Chinese verbs can not be differentiated by their comformations resulted from different roles in a sentence because Chinese words//characters have fixed form and  can not be transformed. Any software system aimed at Natural Language Understanding (NLU) inputs a text string as source and outputs a special text string as object whose structure has been analyzed. The verb-driven model are usually adopted as linguistic pattern in  most NLU systems, therefore the distinguishing of the verbsí» roles   becomes the basic task that will affect the following process of NLU deeply, and the phenomenon of non-morphodifferentiation of Chinese verbs becomes a dilemma for NLU.

Under the guidance of the Hierarchical Networks of Concepts (HNC) theory founded by Prof. Zeng-yang HUANG, this dissertation conducts a survey of the status of verbsí» roles and puts forward serial rules for processing the phenomenon of non-morphodifferentiation of verbs. The processing tips are divided by three classes as following:

Ø        Intra-String (characterized by ending symbol as comma) processing;

Ø        Inter-String (characterized by ending symbol as full stop) processing;

Ø        Sentence-Group processing.

Besides, this dissertation sheds light on the nature of processing rules and sets up a model for dispatching relative rules to solve special problem.

As to methodology, this dissertation employs mainly induction and statistic method in the part of linguistic depicting, deduction and theoretical explanation in the part of processing rules, and philosophical expatiation and analysis in the last part.
