摘　　要：为实现无公害农产品认证资源共享的个性化和智能化,促进无公害农产品品牌化销售,提出了一种基于领域本体的用户建模方法.通过无公害农产品认证资源本体的构建实现以领域本体中的概念和实例表示的用户特征模型,增加用户模型语义信息,并提供了模型的更新算法.结果表明,该方法能够提高用户特征模型表达的准确度.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 usermodeling 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 const- ructed 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.
