The Automatic Analysis of Chunk-Extension Sentences

The chunk-extension sentence is a kind of sentence, which is defined with specific conceptual knowledge in the theory of hierarchical network of concepts. This paper introduces some semantic categories of chunk-extension sentences and related typical verbs. By these typical verbs, the eigen semantic chunk and semantic category of a chunk-extension sentence can be activated. The semantic structure of a sentence can be revealed after testing with the transcendent conceptual knowledge of chunk-extension semantic categories. An experiment was done for automatically analyzing chunk-extension sentences based on a system of analyzing the semantic categories of sentences. The precision of the experiment is 71.29%. The errors are mainly caused when recognizing the head verb and selecting the right semantic category from the multi-semantic-category of a verb. The well analyzing result of chunk-extension sentences will be helpful to tackle the multi-verb puzzle in processing Chinese sentences.
