Today’s digital libraries are extreme complex information systems, which run on the Internet [1]. The facilities of digital libraries are increasing daily as the technology advances with a motive to provide the appropriate information to its users. The very purpose of the digital libraries is to provide the required information to its users in a convenient and fashioned manner. Since the digital libraries are running on the Internet and the users are from different psychological, educational and social backgrounds, the usage of digital libraries is varying from user to user which entail the need of best user interface. Hence, this paper proposes some design principles for user interfaces for digital libraries for its effective implementation. Read More Read Less

Web service invocation occurs over the Internet, which is a public network. This increases concern of the requester for adequate security of his private data. While using the web services, the security requirements of the user usually pertain to confi dentiality, integrity, authentication and non-repudiation for the input information that the user provides and the information received as output from different services. For message level security, specifi cations such as WS-Security are available that use existing algorithms. Different service providers may use different algorithms for security; however, there is presently no mechanism available to the user to discover the service providers supporting the algorithms of their choice. In this paper this important issue has been addressed and an approach to enable a service provider to publish the information related to the security support offered by it has been presented. The presented approach facilitates the service requester to discover the providers as per his security related needs. The presented method is general and easy to use as existing Application Programming Interfaces (APIs) for publishing and discovery of services in the registry are used. Read More Read Less

Abstract Knowledge service has not been a strange information technology since web users can actively query and serve useful knowledge. In this paper, we present SeWeb, which is an effective and effi cient knowledge recommending system using classical P2P technology based on super nodes.

Knowledge service has not been a strange information technology since web users can actively query and serve useful knowledge. In this paper, we present SeWeb, which is an effective and effi cient knowledge recommending system using classical P2P technology based on super nodes. Super nodes are users with fast, mobile connections. This paper has solved two problems: (1) how to construct knowledge services model pointing to Web application; (2) how to eliminate misunderstanding applied knowledge services on Web Platforms. SeWeb Platforms make sure of effi cient information communication because of HTTP protocol. SeWeb can construct wider P2P networks (VPNs) whose goal is to serve knowledge of various kinds. Besides, we show one application interface: SeCollege, which is a sort of real time document resources provider. SeCollege users can upload or download needed documents wherever physical location is. From evaluation results, the emergency of Server Platform has brought vast, great convenience to users. Read More Read Less

It aims at fi ghting for the effective and effi cient Expert-diagnosis process when various symptoms are to be distributed by the root knowledge mainbody in health care knowledge fl ow. The IREX-1 method can eliminate decision tree, creatively abstract knowledge entropy so as to improve the speed and accuracy of diagnosis- decision results. On this purpose, the authors use digestive diseases diagnosis prototype to justify the validity of this method, and do the comparison with renowned ID3,C4.5, ILA, ILA, 2 and original REX-1 algorithms when used in medical health care expert-diagnosis situation.

This article aims at proposing a new version of the Web, called The Web 2.2. This version tries to resolve the problem of the actual Web, such as the non-participation of the internet users on the production of the on line content, the huge mass of information, the poor quality of information, the non-respect of the copyrights and the commercial goal of the Web 2.0. Its objective is to add concepts related to the management of users by introducing a validation board and the management of information by offering 5 levels of quality of information. It focuses on the validation of information produced or proposed by users, and a control board of the diffusion of the content, in charge of the diffusion of the information, from its conception to its elimination or archiving. It encourages the users to participate actively in the production of the content of high quality and adds also the notion of the Web dollars, a virtual currency, which will allow users to take benefi t from payable services available on this version of the Web.
