TVGuide2.0: applying the Web2.0 fundamentals to IDTV

In this paper we introduce our experiences in applying the Web 2.0 philosophy to build a TV guide system for Interactive Digital TV (IDTV) platforms. Subscribers give their opinion about TV content and, informally, a folksonomy is progressively built. Based on this shared knowledge, the TV guide obtains personal recommendations and allows users to browse among the multimedia content. Additionally, and over this collaborative layer, a more formal vision enables applying semantic reasoning to supplement the knowledge informally inferred.

Aware Community Portals: Shared Information Appliances for Transitional Spaces

People wish to maintain a level of awareness of timely information, including presence of others in the workplace and other social settings. We believe this provides better exchange, coordination and contact within a community, especially as people work in asynchronous times and distributed locations. The challenge is to develop lightweight techniques for awareness, interaction and communication using shared information appliances. In this paper, we describe the design of an exploratory responsive display projected within a shared workspace at the MIT Media Lab. The system uses visual sensing to provide relevant information and constructs traces of people’s activity over time. Such aware portals may be deployed in casual workplace domains, distributed workgroups, and everyday public spaces.     

Mean-Extended Gini Portfolios: A 3D Efficient Frontier

Using a numerical optimization technique we construct the mean-extended Gini (MEG) efficient frontier as a workable alternative to the mean-variance efficient frontier. MEG enables the introduction of specific risk aversion into portfolio selection. The resulting portfolios are stochastically dominant for all risk-averse investors. Solving for MEG portfolios allows investors to tailor portfolios for specific risk aversion. The extended Gini is calculated by the covariance of asset returns with a weighing function of the cumulative distribution function (CDF) of these returns. In a sample of asset returns, the CDF is estimated by ranking returns. In this case, analytical optimization techniques using continuous gradient approaches are unavailable, thus the need to develop numerical optimization techniques. In this paper we develop a numerical optimization algorithm that finds the portfolio optimal frontier for arbitrarily large sets of shares. The result is a 3-dimension MEG efficient frontier in the space formed by mean, the extended Gini, and the risk aversion coefficient.     

Browsing the 3D Web

Ajax技术在Web2.0网站设计中的应用研究

Ajax是Web领域的前沿技术,这种技术提供了新的互联网交互模型,并扩展了Web应用的能力。文中在介绍Ajax技术的工作原理、分析比较Ajax工作模式与传统Web工作模式区别的基础上,运用Ajax技术实现了网页的动态加载,用户的请求能更为迅捷地得到Web应用程序的回应。这样就避免了在网络上频繁地重复发送那些没有更新过的信息。相对于传统的Web应用,Ajax技术在丰富客户端的表现能力、改善用户体验中,表现了强大的交互性能。其原因在于Ajax技术实现了客户端与服务器间的数据通信,并提供了两者间异步通信的能力,因而降低了网络传输的数据量,均衡客户端与服务器间的负载。从而体现了Ajax技术提高系统效率与优化用户界面的优良性能。
