基于合作贡献的移动社会网络自私路由协议

移动社会网络的路由工作中存在一个不合理的假设,即所有节点是无私合作的,愿意为其他节点转发数据.然而,MSN网络节点通常表现出自私性,因为在现实世界中,节点通常被人们所支配,而社会中的人们可能由于节点资源的匮乏不愿意节点参与转发.这种节点的自私行为无疑极大地降低了网络的性能.为了解决移动社会网络的自私路由问题,提出了一种...     

Competition and Information Deception in Online Social Networks

This study empirically examines the role of competition in determining intentions toward personal information deception (PID) among users of online social network (OSN) sites. PID refers to OSN users intentionally misrepresenting or refusing to disclose online personal information. The research proposes that consumers’ intentions toward PID depend on their desire for online competition with other OSN users, which in turn depends on user appraisals of available status and hedonic benefits, as well as established social norms around competition. An analysis of data gathered from 499 OSN participants (students enrolled at a state university in the southeastern United States) shows that competitive desires represent an important antecedent of PID behavior in OSN contexts. Theoretical and practical implications of the research are also discussed.     

基于位置的社会化网络推荐系统

近年来,基于位置的社会化网络推荐系统逐渐成为位置服务和社会网络分析的活跃课题之一.挖掘用户签到位置轨迹和社交活动数据,提取用户社会活动的地理空间特征模型及其与社会关系的关联性,设计合理的推荐算法,成为当前基于位置的社会化网络推荐系统的主要任务.该文从分析基于位置的社会化网络的结构特征人手,对基于位置的社会化网络推荐系统的基本框架、基于不同网络层次数据挖掘的推荐方法及应用类型等进行前沿概况、比较和分析.最后对有待深入研究的难点和热点进行分析和展望.     

SMEs and Mass Collaborative Knowledge Management: Toward Understanding the Role of Social Media Networks

ABSTRACT

This article proposes that mass collaborative knowledge management (MCKM) and social media networks (SMNs) tend to enhance productivity in small- and medium-sized enterprises (SMEs). A case study methodology was employed to highlight the complementary advantages of MCKM related to the use of SMNs in a small business operating in southern Italy. The research aims to contribute to the ongoing discussion on MCKM. This article offers a fresh perspective by discussing the relevance of this construct for SMEs.     

基于Web2.0社会性软件的个人学习环境的探究

Web2.0这一互联网新一代模式以其个性化、共享性、开放性等特点为传统网络信息管理提供了一种全新的解决方法。而个人学习环境是自由的、分布的、以网络为基础的工具的集合,以blog为聚焦点,通过RSS订阅器整合内容形成的一个环境,更多的是关于社会性软件的应用。通过网络以及web2.0社会性软件构建一个较全面的个人学习环境,使学习者以个人主导者的身份来管理自己的学习,对学习的管理从教育机构转移到学习者自身,不仅实现内容和知识的简单转移,更演化到了内容和知识的创造与产出。
