A large number of Web services are already available on the Web, and the type and number of Web services are growing on a daily basis. As the Web service paradigm becomes popular and more and more applications are developed or deployed as Web services, the need for defining different matches of Web services becomes manifest. This has raised an interesting research point for defining Web service matches. We concentrate on the vital part of Web service matching - capability matching - and formally analyse and define exact match and plug-in match of Web service capabilities using abstract finite-state machine approaches. Based on the above work, we propose a new lightweight capability description language of Web services (SCDL) and explore the major stages of service capability matching. We then focus on plug-in match and formally define it using formal logic methods. Moreover, we provide feasible approaches and solutions for comparing two service capabilities. The work presented in this paper lays down a solid foundation for tackling the challenges of Web service discovery and composition.

In several hypermedia applications it is usual to face certain user impatience with long waiting times for presenting a media content. In other circumstances, even a short delay may impair the user interactivity or the synchronization among media objects, decreasing the presentation quality or generating an unintelligible presentation. In order to lessen these problems, the use of prefetching techniques is being taken into account in multimedia/hypermedia document presentation systems'. This paper investigates the requirements for designing and implementing prefetching techniques in hypermedia formatters. Based on these requirements, the paper proposes a generic architecture to be adapted and reused in specific formatter developments. Besides the proposed architecture, we specify interfaces in order to make easier the integration of the prefetching mechanism with other hypermedia presentation system components, allowing the incorporation of prefetching strategies in formatter implementations currently in use.

Digital watermarking is an enabling technology to prove ownership on copyrighted material, detect originators of illegally made copies, monitor the usage of copyrighted multimedia data, and analyze the spread spectrum of data over networks and servers. Most watermarking methods for images and video can be viewed as a communications problem in which the watermark must be transmitted and received through a watermark channel. This channel includes distortions resulting from attacks and interference from the original digital data. It is well accepted that an effective watermarking scheme may be described as the secure, imperceptible, robust communication of information by direct embedding in, and retrieval from, digital data. For verifying the security and robustness of watermarking algorithms, specific attacks have to be applied to test them. By using a theoretical approach based on random processes, signal processes, and communication theory, we propose a stochastic formulation of a new watermarking attack using a blind source separation-based concept. The proposed attack considers the watermarking channel as a "black-box". A host image was passed through the "black-box", which includes the watermarking embedding process, and then the watermarked image was produced The watermarked image is viewed as linear mixtures of unknown source signals, and we attempt to recover sources from their linear mixtures without resorting to any prior knowledge by using blind source separation theory.

Although many search engines provide relevantly good search results to the user, they do not consider personal, domain-specific preferences in their searching or ranking algorithms. In an intranet environment we could collect background information about users such as their expertise. If we can accumulate, categorize and personalize Web usage information, it can be used to help the user search Web pages efficiently and effectively. Data analysis and mining can further facilitate Web searching in an intelligent way. This paper describes Internet Search Advisor (ISA), a personalized, knowledge-driven search system that helps the user find informative Web sites. The ISA supports multi-dimensional data analysis and data mining based on association rules and sequential patterns.

This paper describes a framework for providing multimedia, multimodal, distributed services using the session initiation protocol (SIP) and Web services technologies. Within the framework, there is a service platform consisting of the SIP application server, which is used to build call routing/telephony and IMPP (instant message and presence) services using SIP servlets, and a Web application server. There are also distributed service building blocks providing basic building blocks such as an IVR system, media server, TTS server and conference server. All these building blocks from different vendors can be registered in the UDDI registry for dynamic binding at run time. SOAP is used to transfer control information among different components. Meanwhile, the building blocks can be packaged as deployable units with an SIP interface for establishing IMPP and media sessions and with a SOAP interface for providing dynamic control information. The proposed framework will be beneficial to service developers so that they can use familiar Web development tools instead of proprietary APIs to develop new media applications. It will be also useful for service providers or integrators to easily and quickly deploy new services, which are allowed to be distributed remotely and configured using standard protocols. In addition, the proposed framework will be helpful for end users to access innovative multimedia services, which offer interactions with different features at relatively low cost. It is shown that a number of innovative services could be built using this framework.

This paper examines the impact of different physical modes on network QoS parameters such as throughput, bit error rate, and retransmission delays. An efficient technique for the transmission of MPEG-2 bit stream over HIPERLAN/2 networks is presented that exploits the hierarchical structure of the MPEG-2 bit stream. We show that for a given video bit stream use of multiple modulation schemes chosen based on the characteristics of underlying video data yields superior throughput and better picture quality in terms of PSNR.

The acceptance of a standard VoiceXML format has facilitated the development of voice applications, and we anticipate a similar facilitation of pen application development upon the acceptance of a standard InkXML format. In this paper we present a multimodal interface architecture that combines standardized voice and ink formats to facilitate the creation of robust and efficient multimodal systems, particularly for noisy mobile environments. The platform provides a Web interactive system for generic multimodal application development. By providing mutual disambiguation of input signals and superior error handling this architecture should broaden the spectrum of users to the general population, including permanently and temporarily disabled users. Integration of VoiceXML and InkXML provides a standard data format to facilitate Web based development and content delivery. Diverse applications ranging from complex data entry and text editing applications to Web transactions can be implemented on this system, and we present a prototype platform and sample dialogues.

In this paper we describe an authoring environment which allows the author to set up and test a complex multimedia presentation by defining the synchronization relationships among media. The main component of the authoring environment is a visual editor based on a graph notation, in which the nodes are media objects involved in a multimedia presentation, and the edges are the synchronization relations between them. Several external representations can be generated: a timeline-based representation highlighting media sequencing, and an XML-based description suitable for further processing. An execution simulator helps the author to check the presentation behavior before delivery.
