基于社会网络分析的社会化问答平台用户画像研究

Research on User Profile of Social Q&A Platform Participants Based on Social Network Analysis

本研究基于社会网络分析方法构建社会化问答平台用户画像,揭示用户社交行为特征,为用户分类管理和个性化服务提供决策依据。本研究利用网络爬虫技术获取Quora中高血压主题下的用户社交行为数据,构建不同类型用户社交网络,分析用户社交网络结构和用户社交类型的特征,进而生成面向高血压主题的用户画像。研究结果表明,将社会网络分析方法运用到用户画像研究中,能够有效地挖掘、组织和表示用户社交行为特征;基于节点特征值分布的用户分类方法可以实现用户细分;用户画像有助于平台管理人员对用户社交和分类管理形成更深层次的认知。本文为社会化问答平台用户画像实现提供了借鉴和参考,也为社会化问答平台用户画像的应用奠定了基础。

Based on social network analysis,this study aims to construct a profile of user participants on social Q&A platforms,revealing users'social behavior toward a specific topic and providing advice for user classification and personalized service.This study uses the web crawler to obtain user social behavior data on the topic“Hypertension”on Quora and constructs users'different social networks.The characteristics are then revealed in terms of two aspects:user social network structure and user social type,from which the user profile is generated.The study shows that social network analysis can effectively mine,organize and represent the characteristics of users'social behavior.The user classification method based on the value distribution of node feature can realize users'segmentation.Moreover,the user profile can also help the platform managers to form a deeper understanding of the user social interaction and classification management.This research would become a reference for user profile generation of social Q&A platforms and provide a basis for applying user profiles of social Q&A platforms.
