Constructing User Characteristics Model in Sharing System of Pollution-free Agricultural Products Certification Resources |
| |
| Abstract: | In order to improve the level of personalized and intelligentialize of sharing system of pollution-free agricultural products certification resources and promote pollution-free agricultural products saled by brands,a user modeling method based on domain ontology is proposed.Through the establishment of pollution-free agricultural products certification resource ontology,a user characteristics model composed of concepts and instances is constructed and it has more semantic information.Moreover,a user characteristics model updating algorithm is provided.Experiments show that this method can improve the accuracy of user characteristics model. |
