The original idea of the World Wide Web was to create a universe of network-accessible information. Since its inception, the World Wide Web has evolved from a means to help people access and use information into an interactive medium. This has caused a dramatic increase in the development effort for interactive services, which now have to support multiple clients with widely varying computing and user interface capabilities. Personalization features tend to render this task even more complex. The paper presents the MUSA (Multiple User Interfaces, Single Application) system, which addresses both issues with the introduction of an event graph that abstracts user interface and personalization issues from the implementation of the service on different client-devices.  相似文献

Decision making is one of the most important activities for human beings. Complex decision making problems are full of uncertainty and ambiguities. A large amount of data is needed and several strategies must be applied at the same time in order to get a good decision. Research about decision support systems has been proposed to help people effectively solve these kinds of problems. Recently, World Wide Web applications have grown very rapidly and have made a significant impact on computer systems. In this paper, we propose a framework for Internet computing on decision support systems by modifying traditional decision support systems on the World Wide Web. Modules of the proposed framework were also designed to meet the requirements of both decision support and Internet computing. An actual implementation of a travelling schedule domain was conducted to show the feasibility of the proposed framework. The proposed framework provides a feasible solution to building World Wide Web decision support systems in real applications.  相似文献

Interactive voice browsers offer an alternative paradigm that enables both sighted and visually impaired users to access the World Wide Web. In addition to the desktop PC, voice browsers afford ubiquitous mobile access to the World Wide Web using a wide range of consumer devices. This technology can facilitate a safe, ‘hands-free' browsing environment which is of importance both to car drivers and various mobile and technical professionals. By providing voice-mediated access, information providers can reach a wider audience and leverage existing investment in their World Wide Web content. In this paper we describe the Vox Portal, a scaleable VoxML client, and a World Wide Web Server-hosted dynamic HTMLVoxML converter.  相似文献

Despite the prominence of the World Wide Web in people’s everyday lives, most Web presences in private sector organizations still fail to comply with contemporary accessibility standards. As a consequence, a large group of users—i.e., people with impairments—are excluded from accessing these Web presences. In order to explain the managerial rationale, an exploratory case study was conducted in three industry sectors. The results of the analysis shed light on organizations’ motivations to implement or reject Web accessibility standards, reveal positive and negative consequences of implementation, and provide in-depth insights into the determinants for successful and unsuccessful Web accessibility implementation. This study supports organizations in making better decisions on the implementation of Web accessibility.  相似文献

The World Wide Web (Web) allows people at remotely located sites to communicate and share their ideas using a common communication protocol. A common use of the Web system is running a client application, using a browsing tool, by pointing to a local or proxy server to browse data written in the hypertext format that contains anchors that address other URLs. In this paper a new application of the Web system for sharing knowledge-based systems and groupware development activities is introduced. An architecture for a Web-based Distributed Expert System (Ex-W-Pert System) is proposed and an implementation of the proposed architecture in groupware design is demonstrated. The resources and knowledge bases are distributed and can be accessed through the internet.  相似文献

The Web offers a single user interface to data sharing across heterogeneous and autonomous databases, but it was not designed to handle the rigid DBMS protocols and data formats used by relational and object-oriented databases. WebFindIt is an ongoing project to develop the database equivalent of the World Wide Web-namely, a World Wide Database-through a middleware infrastructure for describing, locating, and accessing data from any kind of Web-accessible database. A special-purpose language, Web-Tassili, supports the definition and manipulation of middleware constructs for organizing the information space. An implementation of WebFindIt combines Java, CORBA and database technologies  相似文献

This paper describes a metadata based indexing system with a built-in expert system for cataloging and searching digital libraries on the World Wide Web. The specific features of this system are the following: An expert system with a knowledge base and a subject thesaurus, a model of a reference librarian's behavior for cataloging and searching, and an intelligent user interface to provide context sensitive help to the user. At present our expert system is limited to the subjects of Computer Science and Electrical Engineering. The design issues and the implementation details of the expert system to mimic a librarian's behavior for automated document searching and cataloging are discussed in detail.  相似文献

The World Wide Web consortium is a group of about 370 international companies working together to develop recommendations, or Web standards, for the World Wide Web. W3G announced final approval of two key semantic Web technologies: the revised RDF and OWL. RDF and OWL are semantic Web standards. These standard formats for data sharing span application, enterprise, and community boundaries share the same information, even if they don't share the same software.  相似文献
