Abstract


\Body can be recognized types of knowledge into specifications , in the form of a computer can understand . However, there are really put into use ontology and related scientific research is also very small , mainly due to existing ontology -based artificial period involving a number of experts to assist experts in the field , also called concepts and relations related fields with a clear and comprehensive understanding of the investment in resources , long construction period, not guarantee the quality and other problems have seriously restricted the application of the body . The ability to quickly and easily get the concept and knowledge of a particular field , and automatically converted to domain ontology , to some extent, determines the speed of the main body of the application and promotion of . The body automatically build the technology is research around this problem . Body theory , comparative analysis of the text preprocessing , feature extraction, knowledge pattern extraction and knowledge - mode evaluation of text mining algorithm, combined with the body automatically build the guiding ideology of multiple stages in the process , detailing its build tools and construction methods . On the basis of theoretical research , the development of text mining analysis tools and body build tools automatically build a prototyping system automatically based on the body of the text mining . On the basis of the work to collect the relevant information in the field of teaching , and the standardization of finishing , so the need for text mining and ontology , the ontology automatically build automated build system successfully teaching domain ontology . The practical application of teaching that through text mining - based ontology automatically build technology research, development analysis build tool , can greatly shorten the ontology construction project cycle to reduce the input of experts in the field of ontology construction process , saving a lot of costs, while managing to avoid artificial constructs body , due to the impact of knowledge, professional , understanding between experts in the field is not uniform within the body caused by inconsistencies and errors caused by people who do not carefully , thus improving the quality of the build body , body provides a good technical support .
