虚拟医疗社区中用户相似度计算方法

Computing Algorithm of User Similarity in Virtual Medical Communities

用户相似度计算在协同过滤系统、用户推荐系统以及社交网络中有着非常重要的作用。在对虚拟医疗社区用户关系进行分析的基础上,提出一种基于医学主题词表的用户相似度计算方法。在虚拟医疗社区的平台上用户可以进行信息咨询以及相互交流,从而有效分配医疗资源。

User similarity computing plays a very important role in collaborative filtering systems,user recommendation systems as well as social network services.Based on the analysis of user relationships in the virtual medical communities,the paper proposes a user similarity computing algorithm based on Medical Subject Headings（MeSH）.On the virtual medical communities＇platform,users can get information consult and mutual communication,so as to effectively allocate medical care resources.
