The benefits of integrating and collaborating with supply chain partners have been well identified in many industries. In the construction industry, however, supply chain integration and collaboration is challenging due to the high fragmentation and the temporary project-based nature of the industry. Leveraging web service and web portal technologies, we have developed a prototype web service s...

International open government initiatives are releasing an increasing volume of raw government datasets directly to citizens via the Web. The transparency resulting from these releases creates new application opportunities but also imposes new burdens inherent to large-scale distributed data integration, collaborative data manipulation and transparent data consumption. The Tetherless World Cons...

A wind tunnel simulation requires high-performance computing power like supercomputers and deep knowledge of this subject. Those requirements make win tunnel simulation difficult. Grid technology will make these difficulties simpler by providing easy to use grid web portal. By using grid web portal, scientist can execute simulation and access to highperformance computing power without any serio...

F are investing millions to deploy Web-based self-services at their call centers. The rationale for such investment is that the firm’s cost of interacting with its customers through the Web-based channel is an order of magnitude cheaper than the assisted channels such as telephony. We conduct a field study at the call center of a prominent U.S. health insurance firm to examine this cost-saving ...

We present Beem — BEnchmarks for Explicit Model checkers. This benchmark set includes more than 50 parametrized models (300 concrete instances) together with their correctness properties (both safety and liveness). The benchmark set is accompanied by an comprehensive web portal, which provides detailed information about all models. The web portal also includes information about state spaces and...

One of the main shortcomings of Semantic Web technologies is that there are few user-friendly ways for displaying, browsing and querying semantic data. In fact, the lack of effective interfaces for end users significantly hinders further adoption of the Semantic Web. In this paper, we propose the Semantic Web Portal (SWP) as a light-weight platform that unifies off-theshelf Semantic Web tools h...

Web 2.0 technologies such as wikis, podcasts/vodcasting, blogs and semantic portals could be quite effective tools in e-learning for health professionals. If effectively deployed, such tools can offer a way to enhance students', clinicians' and patients' learning experiences, and deepens levels of learners' engagement and collaboration within medical learning environments. However, Web 2.0 requ...

Building data-intensive Web sites and especially Web portals is a costly task, which requires considerable effort for data integration and maintenance and usually does not result in many reusable components. This is mainly because most of the design is hard-coded in static or dynamic Web pages. In this paper we integrate three different approaches to create a comprehensive solution to Web site ...

Portlets-based software development is gaining recognition as a key technology for the construction of robust and evolvable Web applications. Emerging portlet standards like JSR-168 or WSRP—along with commercial development tools and portal servers—enable designers to quickly develop, integrate and run “composite” Web portals, which integrate specific platforms and partners. Despite this signif...

1. Introduction Web-based Course Management Software (CMS) provides a single portal for students and teaching staff to collaborate in an elaborate interactive environment. This portal provides tools for online submissions, examinations, student performance monitoring, discussion threads, real-time chat, and electronic mail. In higher education, these facilities are becoming more common for deli...
