A method for fusing incomplete demand information based on information similarity

摘要

Due to customer's different knowledge background and interests, the demand information is different on presentation and content. A unified information model is built up to standardize information, which includes the demand framework, the effective demand item and the basic desirous function. Based on the information similarity, a fusion method is given to synthesize incomplete information. The steps of the method are relating information, computing relevancy with the incidence matrix and getting weights of customers, etc. Finally, an application in the customer information system is given to verify the feasibility and effectiveness of the model.
