中文摘要: 近年来随着参与人数迅猛增长,在线社会网络已经成为信息发布共享,工作求职,产品推荐等活动的重要网络平台。由于参与者之间的信任影响着服务和产品的选择,信息的传播等。因此信任成为了支持人们网络社交的重要参考指标,具有重要的研究价值。已有在线社会网络信任评估方法存在许多缺陷,包括没有考虑复杂社会信息对信任评估的影响,没有分析复杂社会行为,没有考虑不同行为模式对信任推理的影响等。根据社会科学相关理论,这些因素对信任评估具有重要影响。因此已有方法不能合理准确的评估参与者之间的信任。本课题针对目前研究方法存在的缺陷主要研究:(1)根据复杂社会行为研究大规模在线社会网络中复杂社会信息挖掘方法;(2)根据复杂社会行为与社会信息,研究建立社会层次模型;(3)在此基础上挖掘具有社会联系的参与者之间的直接信任关系;(4)推理参与者之间的间接信任关系,并研究高效查询算法查询网络中高可信(或非可信)的参与者。

英文摘要: With the increasement of participants in Online Social Networks (OSNs), OSNs have become one of the most important platforms for information publishing and sharing, employment and product recommendations. As the trust between participants have significant influence on service and produce selections and information dissemination, etc. Therefore, trust has become one of the most important indications for patcipants decesion-making for social activities in OSNs, and thus trust becomes a significant research topic in OSNs. The existing trust evaluation mechinisms have some drawbacks. I.E.,they do not consider the complex social information in trust evaluation, and they do not analyze the complex social behaviors and consider the influence of different behavior patterns on trust inference. Based on the theories in Social Science, the above aspects have significant influence on trust evaluation. Therefore, the existing methods cannot deliver reasonable and accurate trust values between participants. To address the above drawbacks, the studies of this project will mainly focus on: (1) Based on the complex social behaviors in large-scale OSNs, developing data mining methods to mine complex social information. (2) Based on the complex social behaviors and social information, constructing social hierarchy for participants
