摘要
作为通用的知识结构化表示形式,知识图谱被成功应用于医疗、金融、安全等领域.社交知识图谱是一种以人为中心的知识图谱,其融合了动态演化的社交知识.作为知识图谱概念的延伸,社交知识图谱涵盖人、物、事、地等异质信息及其复杂关联;由于其融入了来自社交网络的强时效性知识,能够准确地描述人员的即时状态及其演化趋势,被广泛应用于推荐系统、社交分析等以人为中心的应用中.当前,社交知识图谱的相关工作不断涌现,但缺乏统一的形式化定义以及系统性的分析.基于此,本文首先梳理了社交知识图谱的相关概念,并给出了社交知识图谱的形式化定义.然后从社交知识图谱的定义出发,对其动态性、异质性、情感性、互演化性等性质进行分析.接下来围绕社交知识图谱的生命周期,梳理了社交知识图谱的构建、融合、表示和推理的相关代表性工作.最后介绍了社交知识图谱的相关应用,并展望了社交知识图谱的未来发展蓝图.
Knowledge Graph(KG)has received great attention and has been widely explored since its inception.Recently,there is a trend to introduce social information from Social Network(SN)into KG called Social Knowledge Graph(SKG).SKG is a kind of Knowledge Graph,which is human-centered and dynamic.It contains rich background information from KG and dynamic interaction information about people from SN.Considering that the information complementation of SN and KG can benefit human-oriented applications such as recommendation systems and social analysis.It is essential to propose a unified framework for the integration of SN and KG.However,there is currently no survey focusing on this research trend.In this paper,we introduce the SKG and give a systematic analysis of it.Specifically,we first introduce relevant concepts about SKG,and propose a formal definition of it.Next,we analyze the characteristics of SKG from four perspectives including heterogeneous,dynamic,emotional and coevolutionary.Then,around the life cycle of the SKG,we introduce the relevant representative studies of the SKG construction,representation,integration and reasoning.Finally,we introduce the related applications of SKG,and discuss its valuable future direction.
