互联网已经从一个小型网络转变为一个规模巨大的巨大基础设施。Web上的公共可访问数据量(托管在全球数百万台服务器和数十亿个Web页面上)正在接近Exabyte极限。考虑到这些数据的巨大规模,并继续快速增长,该项目询问是否有可能镜像内容,即,将其表示为已经在线可用的大量数据的函数。因此,一个相关的问题是,整个互联网是否可以被视为一个单一的内容分发网络。也就是说,通过从公开可用的Web服务下载镜像内容片段,是否可以收获可能不存在于因特网上任何一个特定位置的所需内容?PI建议将mashup内容收获作为一种旨在实现上述目标的综合方法。在这种方法中,用户有能力和手段,其中PI将开发,创建或复制内容表示它在大量的数据公开在网上。通过使用户能够有效地将新数据镜像为现有数据的函数,实现大规模内容分发变得可行,而无需托管任何新的服务器或对等基础设施。相反,隐写术的方法,明确地嵌入信息写入载体medium,prosed系统有效地反映到现有的公开可用的内容,没有任何明确的writing.Intellectual优点:拟议的研究将解决基本问题,是关键的开发和部署mashup内容收获。主要的挑战是(i)如何通过公共访问站点上的信息嵌入数据和跳跃信息,(ii)如何选择一组核心数据段以最大限度地提高镜像效率,(iii)如何设计和部署方法,以可扩展和准确地表征mashup内容收获数据载体,(iv)哪些基本的Web载体属性可以实现有效的mashup内容镜像和收获,(v)影响系统性能的Web页面多样性和连接性的下限是什么,(vi)mashup内容采集在封闭的国家级Web环境中的表现如何,以及(vii)当内容载体仅限于与特定世界语言相关联的Web页面时,mashup内容采集的表现如何。该项目有能力通过促进自由和开放的互联网的发展而产生重大影响。其实,自由,非商业性的Web服务为互联网上的众多个人和组织创造了巨大的价值。这些服务的共同点是利用世界各地个人的社区贡献。不幸的是,尽管有热情的合作贡献,现有的免费Web服务并不是真正免费的。例如,维基百科必须筹集大量资金来支持其托管成本。Mashup内容收集为在线社区提供了一种可行的方法,无论它们有多小。这既不可能通过威胁或与商业主流Web服务竞争来实现,也不可能影响它们的性能。PI计划将mashup内容收集设计和传播为易于使用的浏览器插件。
英文摘要
The Internet has transformed from a small network into a gigantic infrastructure of enormous scale. The amount of publicly-accessible data on the Web, hosted at millions of servers and billions of Web pages around the world, is approaching the Exabyte limit. Given the enormous size of this data, which continues to grow at a rapid pace, this project asks if it is possible to mirror content, i.e., represent it as a function of the massive data already available online. Consequently, a related question is if the entire Internet can be treated as a single Content Distribution Network. That is, can one harvest the desired content, which may not exist at any one particular location on the Internet, by downloading pieces of mirrored content from the publicly available Web services?The PI proposes mashup content harvesting as a comprehensive approach that aims to accomplish the above goals. In this approach, users have the ability and means, which the PI will develop, to create or replicate content by representing it in terms of the significant amount of data publicly available on the Web. By enabling users to effectively mirror new data as a function of existing data, it becomes feasible to achieve mass-scale content distribution, yet without hosting any new server- or peer-to-peer infrastructure. Contrary to steganography methods, which explicitly embed information by writing it to a carrier medium, the prosed system effectively mirrors data onto existing publicly-available content without any explicit writing.Intellectual Merit: The proposed research will address fundamental questions that are key to developing and deploying mashup content harvesting. The major challenges are (i) how to embed both data and hopping information via information available on publicly accessible sites, (ii) how to select a set of core data segments to maximize mirroring efficiency, (iii) how to devise and deploy methods for scalable and accurate characterization of mashup content harvesting data carriers, (iv) which fundamental Web carrier properties enable effective mashup content mirroring and harvesting, (v) what are the lower-bounds in terms of the Web page diversity and connectivity that affect system performance, (vi) how mashup content harvesting performs in closed national-level Web environments, and (vii) how mashup content harvesting performs when content carriers are limited to Web pages associated with specific world languages.Broader Impact: This project has the capacity to make a significant impact by facilitating the development of a free and open Internet. Indeed, free, i.e., non-commercial, Web services have created enormous value to numerous individuals and organizations on the Internet. Common for such services is to leverage community contributions from individuals around the world. Unfortunately, despite enthusiastic collaborative contributions, existing free Web services aren't really free. For example, Wikipedia must raise large amounts of money to support its hosting costs. Mashup content harvesting provides a feasible approach for online communities to sustain, no matter how small they may be. This is possible to achieve neither by threatening nor competing with commercial mainstream Web services, nor affecting their performance. The PI plans to design and disseminate mashup content harvesting as easy-to-use browser plug-ins.
