Research On Knowledge Base Construction Of Chinese Temporal Characteristic Words Based On Ontology

The research in the field of the Chinese understanding has developed more than30years. Although some achievement of the grammatical analysis and the Chinesecharacter input, etc. have been made, it had no result for the syntax analysis, which isthe core of natural language processing (NLP). Many aspects of the Chineseinformation processing are always more complex and difficult than the wordprocessing, one of the difficulties is the direction of tense in Chinese.Today, it mainly including kinds of corpus of noun, dictionary, dictionary ofsyntax and semantic, and some ontological knowledge base of function words,adverbs and emotional words in the field of knowledge base of the Chinese. Therestill isn’t a ontological knowledge base of information in Chinese time vocabulary.We choose the vocabulary Containing Chinese temporal information as theinstance, use the ontological theory and methods, represent and organize the Chinesetime information words. In this paper, the main work and the key technology is asfollows: First of all, we preprocess the information processing through the technologyof word segmentation technology of natural language processing, extract theAuxiliary word, adverbs, nouns and etc. in the sentence to complete the datastandardization. Next, according to difference of characteristics and semantics of thetemporal information words, extract the interpretable characteristics, describe theseword usage rules using OWL, provide formal basis for the description of the concept.Again, establish the Chinese ontology base and storage using the protégé, useRacerPro for Logic testing and simply inference，interpret the ontology using Jena,and complete to perfect the process of ontology through the Jena technology inontology learning phase. Finally, design and implement a semantic retrieval system,to verify the logical completeness and maturity of the Ontology base.Compared with previous research, we have carried on the new building ofChinese temporal words corpus on this article. Structured process the Chinesetemporal characteristics for polysemy, ambiguity, diversity, and make the tensejudgment more accurate.
