摘　　要：[目的/意义]聚焦社会化问答平台,探索多视角数据驱动的用户画像构建框架和方法,旨在更全面、准确地理解用户,进而为用户提供更优质、精准的信息服务。[研究设计/方法]根据社会化问答平台用户数据的特点,从数据挖掘和本体论的视角厘清用户数据与用户之间的对应关系,在此基础上提出多视角数据驱动的社会化问答平台用户画像构建模型。[结论/发现]该模型包括了用户数据获取、属性沙盒搭建、用户画像实现和用户画像应用等环节,在用户画像实现过程中主要涉及用户画像生成与用户画像更新两个关键环节。[创新/价值]建立了多视角用户数据与用户之间的对应关系,阐述了社会化问答平台用户画像的构建框架与方法。[Purpose/Significance]This study aims to explore the framework and methods of multi-view-data-driven user profile construction for social Q&A platform.It intends to provide a more comprehensive and more accurate understanding of users for service providers,which will help them improve the quality and accuracy of their services.[Design/Methodology]According to the characteristics of user data from social Q&A platform,the corresponding relationship between user data composition and user attribute extraction has been clarified from the perspectives of data mining and ontology.Then a multi-view-data-driven model of user profile construction for social Q&A platform has been proposed.[Findings/Conclusion]The model consists of four parts,which are user data acquisition,attribute sandbox construction,user profile implementation and user profile application.And the part of user profile implementation mainly involves two key steps,user profile generation and user profile update.[Originality/Value]The correspondence between multi-view user data and users has been established,and the framework and methods of user profile construction for social Q&A platform have been expounded.
