With the rapid developments and extensive applications of internet, a large number of duplicated entities on the Web, especially on the Deep Web, require to be eliminated and integrated effectively. So identifying the corresponding entities on the Deep Web is critical. Due to the query interface on the HTML page represents the schema of the Web database, we firstly try to obtain the schema of the...
In order to bear reliable end-to-end services transmission in insecure IP network, SCTP as the transport protocol of the next-generation Internet was proposed. The performance of SCTP has been improved in related literature; however, they optimized it based on a single or a few parameters, which is lack of a comprehensive consideration in correlation parameters. In consideration of real-time and the...
On the coming of the informational age and globalization, SMEs(Small and Medium Enterprises) must adopt electronic commerce to rebuild the traditional operational process of them to face the drastic market competition. With a view to SMEs, the necessity and probability of the E-commerce use in SMEs in details is presented in this paper. The importance of E-commerce for SME's E-commerce is analyzed...
One of the main challenges of using mobile devices as a learning platform is the impermanent network environment due to the wireless coverage or wireless link fail. On the other hand, GPRS or 3G telecommunication protocol offer the persistent connectedness of learning, but comparative weak computing power and very limited network bandwidth cause the learning as time-consuming process. Besides, the...
The Deep Web, a complex entity that contains information from a variety of source types, has gotten a lot of press in recent years. In order to unlock the vast Deep Web content, effective approaches to extract, index and search the query interfaces from dynamic Web pages should be studied carefully. Based on our previously proposed grouping patterns and pre-clustering algorithm, this paper presents...
Web-based risk avoidance group decision support system (RAGDSS) provides a platform for expert group to make risk decisions for software project bidding. In this paper, we study the principle, process, framework and functions of RAGDSS. Finally, we introduce a prototype of RAGDSS based on variable precision rough set (VPRS) model
With the advent of next generation communication infrastructure where Internet and telecommunication network could work together to provide converged services like (messaging, presence and call control), location-based services requires not only flexible and scalable middleware that supports three LBS service models: pull, poll and push, but also advanced converged service platform that supports LBS...
As an advanced technology representing " the third Internet revolution", Grid brings about a lot of innovative ideas and technologies for the development of Decision Support Systems (DSS). As an application of Grid in the field of DSS, this paper puts forward an improved model of DSS based on Agent Grid. A set of design methods of the system is discussed. With the National Economic Mobilization...
