Obtain the expert knowledge from the internet for product innovation design

For the better acquiring knowledge needed by expert from cyberspace in Internet and stimulating inspiration for creation, a method of obtaining group knowledge of generalized expert for product innovation design is proposed in this paper. First, analysis of knowledge sample provided by universal expert is performed, and sample feature is extracted. Then, in response to the features of product innovation design, filed ontology with emotional semantic words is constructed. Based on filed ontology, the vocabulary of sample feature of expert knowledge is extended. On this condition, through searching and filtering, knowledge text of special expert from Internet is obtained. Using extraction technique of knowledge element, knowledge base of generalized expert group is constructed. Finally, an example is given to illustrate the effect of search and filtration of special expert knowledge and the building form and results of knowledge base of generalized expert group.
