基于公开数据的特殊人群在线活动特征挖掘

摘要/Abstract

摘要：

通过采集百度贴吧中的相关数据，从时间、文本、网络3个维度分析不同人群的在线活动特征，探索社会特殊人群的活动规律和心理状态。研究发现，艾滋病人群在线活动更规律，在线活动的主要目的是了解病情知识、记录日记，对本类型贴吧的关注很集中；男同性恋人群活跃时间晚，大多是为了娱乐交友，对本类型贴吧的关注具有很强的偏好性。总体上，艾滋病人群对自身病情十分关心，但男同性恋人群的艾滋病防护意识还不强。

Abstract:

Data from 36 Baidu Tieba was collected.The sub-groups of users from three dimensions of time (temporal),content (text) and interaction (network) were analyzed,and patterns of their online activity were tried to extract and characteristics of different populations was inferred.The result indicates that the temporal pattern of posting behavior is more regular for HIV-related users.Communities followed by these users are also HIV-related,revealing a significant clustering pattern.On the other hand,MSM groups are more active during midnight,and their motivation of online activities in the community is for entertainment and for meeting partners.There is also a strong preference of following the same type of Tiebas for MSM groups.In general,HIV-related users are very concerned about their health status.On the contrary,MSM-related users are lack of awareness for protection and prevention of AIDS.

Key words: hidden population, AIDS, MSM, online features, complex network
