The Method of Extracting Domain and Situation in Chinese Sentence Groups

Sentence group is mapped into contextual element, one of the four layers of linguistic conceptual space in the theory of hierarchical network of concepts (HNC). The contextual element is composed of three parts: domain, situation and background. The domain is extracted by merging sentences with the same or similar domain conceptual symbol, which comes from the symbols of conceptual primitives, the conceptual symbols of words, and the semantic chunks in a sentence. The conceptual framework of situation is filled with the right words or phrases, according to the knowledge of domain sentence categories, the sentence categories and semantic chunks. The experiments show that there are still many aspects to be improved, including the knowledge base, analyzing the semantic structures of sentences, and matching the conceptual symbols in different types.
