在线信誉系统中的信任模型有效性分析 总被引:1,自引:1,他引:0
从理论上证明,由于信任模型存在忽视评分用户信任度的缺陷,现有在线信誉系统难以激励卖者从事持续的诚实交易。针对此问题,构建了基于评分可信度的信任模型。理论分析表明,该模型可有效弥补现有信任模型的不足。 相似文献

小时候看电影是一件很正式的事情。记忆里那个时候的电影院充满着腐朽的气息。昏暗,破旧。售票窗口永远缺一块玻璃,冬天的时候就用报纸糊上。检票员和售票员永远嗑瓜子织毛衣。电影也不新,往往是公映了半年之后,才轮到本地的电影院。因为当年每部电影的拷贝很少,每个拷贝都会被放过上万次,所以很多人记忆中的老电影颜色都会发黄,影像不稳,有很多的划痕和噪点,还有放映机转动的沙沙声,和身后墙上那股打到银幕上的光里的上亿个灰尘粒。 相似文献

Understanding Web 2.0 总被引:2,自引:0,他引:2
《IT Professional》2007,9(4):34-41
Web 2.0, the second phase in the Web's evolution, is attracting the attention of IT professionals, businesses, and Web users. Web 2.0 is also called the wisdom Web, people-centric Web, participative Web, and read/write Web. Web 2.0 harnesses the Web in a more interactive and collaborative manner, emphasizing peers' social interaction and collective intelligence, and presents new opportunities for leveraging the Web and engaging its users more effectively. Within the last two to three years, Web 2.0, ignited by successful Web 2.0 based social applications such as MySpace, Flickr, and YouTube, has been forging new applications that were previously unimaginable. 相似文献

Online 3D Shared Spaces (3DSSs) can be regarded as a frontier of the Web 2.0, where users as participants contribute to create a meaningful, engaging experience. Like other complex web applications, the development and evolution
of high-quality 3DSS applications requires methodological support—through models, methods, and principles. Yet, the application
of structured, engineered approaches to this domain is largely unexplored. The purpose of this paper is to contribute to bridging
Web Engineering to the 3DSS world by means of design patterns. We present five patterns that focus on two factors deemed necessary for effective experiences in a 3DSS: Presence (i.e. the feeling of “being there”, typical of “virtual worlds”) and Long-Term Engagement (typical of successful Web 2.0 communities). The patterns presented in the paper distil our large-scale experiences with
3DSSs (that have involved so far over 9,000 youngsters from 3 continents) and are discussed in the light of existing literature. 相似文献
