社会媒体是一种新型的用户交流平台,其中包含丰富的用户生成资源以及通过对资源的操作而形成的用户社群.社会媒体搜索是关于这些用户、资源及其关系的搜索,构建社会媒体用户和资源关系模型是支持社会媒体搜索的一种有效途径.目前社会媒体搜索的研究已取得了大量的成果,文中基于这些研究成果,给出一个社会媒体搜索系统框架,阐述资源与用户关系建模在其中的作用,将用户和资源均视为"实体",将用户与用户、用户与资源及资源与资源间的关系均视为实体间"关系",将社会媒体搜索归类为"实体搜索"及"关系搜索".基于实体关系模型结构及实体关系的计算方法,分类综述了"实体搜索"及"关系搜索"中的实体关系建模工作的研究现状,分析了社会媒体实体关系建模技术面临的问题和挑战,并展望了未来的研究趋势.
Social media is a kind of new platform for user communication.It contains rich user generated resources and user communities formed by operating the resources.Searching the users,resources,and their relations is the major goal of social media search,which can be realized by modeling the relations among users and resources in social media.There have been a lot of research results achieved on the field of current social media search.This paper gives a social media search system framework based on these results,and describes the effect of modeling users,resources,and their relations in the framework.Moreover,both users and resources are regarded as entities in this paper,the relations among users,among resources,and between users and resources are all regarded as relations among entities,and social media search studies are categorized into entity search and relation search.For the two kinds of search,based on the structure of entity relation model and the relation measure among entities,a comprehensive survey of the relative work in this research domain is given respectively.The paper also analyzes the problems and challenges on the modeling techniques and finally proposes further research directions.
