As one illustration of semantic web technology in action, we present SEMPL, a semantic web portal for the Large Scale Distributed Information Systems lab (LSDIS) at the University of Georgia. SEMPL, which is powered by a state of the art commercial system, Semagix Freedom [7], uses an ontology-driven approach to provide semantic browsing, linking, and contextual querying of content within the portal. By using the ontology based information integration technique, SEMPL can specify the context of a particular piece of research information, annotate web pages, and provide links to semantically related areas enabling a rich contextual retrieval of information.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

But they are designed for sharing and searching the contents in personal computers instead of websites. In this work, we propose a novel web information retrieval method called Site-To-Site (S2S) searching, which uses the P2P framework with CGI as protocol. It helps the site owners to turn their websites into autonomous search engines without extra hardware and software costs. In this paper, we introduce S2S searching with some related work. We also describe the system architecture and communication protocol. Finally, we summarize the experimental results, and show that S2S searching works well in one thousand sites.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

The most famous search techniques are perhaps the PageRank and HITS algorithms. These algorithms are motivated by the observation that a hyperlink from a page to another is an implicit conveyance of authority to the target page. They exploit this social phenomenon to identify quality pages, e.g., \"authority\" pages and \"hub\" pages. In this paper we argue that these algorithms miss an important dimension of the Web, the temporal dimension. The Web is not a static environment. It changes constantly. Quality pages in the past may not be quality pages now or in the future. These techniques favor older pages because these pages have many in-links accumulated over time. New pages, which may be of high quality, have few or no in-links and are left behind. Bringing new and quality pages to users is important because most users want the latest information. Research publication search has exactly the same problem. This paper studies the temporal dimension of search in the context of research publication search. We propose a number of methods deal with the problem. Our experimental results show that these methods are highly effective.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

For a user who wants to examine a number of alternative retrievals, this form of interaction is inconvenient and frustrating. It can be hard work to keep finding and adjusting the parameter specification widgets buried in a Web page, and to remember or record each result set. Moreover, when using diverse Web applicationsin combination - transferring result data from one into the parameters for another - the lack of an easy way to automate that transfer merely increases the frustration. Our solution is to integrate techniques for each of three key activities: clipping elements from Web pages to wrap an application; connecting wrapped applications using spreadsheet-like formulas; and cloning the interfaceelements so that several sets of parameters and results may behandled in parallel. We describe a prototype that implements this solution, showing how it enables rapid and flexible exploration ofthe resources accessible through user-chosen combinations of Web applications. Our aim in this work is to contribute to research on making optimal use of the wealth of information on the Web, by providing interaction techniques that address very practical needs.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

With services such as Akamai's EdgeComputing it is now possible to deploy and run enterprise business Web applications on a globally distributed computing platform, to provide subsecond response time to end users anywhere in the world. Additionally, this distributed application platform provides high levels of fault-tolerance and scalability on-demand to meet virtually any need. Application resources can be provisioned dynamically in seconds to respond automatically to changes in load on a given application.In some cases, an application can be deployed completely on the global platform without any central enterprise infrastructure. Other applications can require centralizing core business logic and transactional databases at the enterprise data center while the presentation layer and some business logic and database functionality move onto the edge platform.Implementing a distributed application service on the Internet's edge requires overcoming numerous challenges, including sandboxing for security, distributed load-balancing and resource management, accounting and billing, deployment, testing, debugging, and monitoring. Our current implementation of Akamai EdgeComputing supports application programming platforms such as Java 2 Enterprise Edition (J2EE) and Microsoft's .NET Framework, in large part because they make it easier to address some of these challenges. In the near future we will also support environments for other application languages such as C, PHP, and Perl.","PeriodicalId":409891,"journal":{"name":"WWW Alt.
