    The purpose of semantic Web services discovery is to use semantic knowledge to find services that can be composed to form an admissible answer to a query. In this paper we consider the advantage of adopting a knowledge-based approach to Web services discovery. Services are described by means of terminological axioms and constrained clauses. We apply a specific resolution and a constraint propagati... View full abstract»

    Web services enhance current Web functionality by altering its nature from document to service-oriented. As the number of Web services increases, it becomes increasingly important to provide a scalable infrastructure of registries that allows both developers and end-users to perform discovery of semantic Web enabled services. The discovery of services needs to be based on QoS characteristics in or... View full abstract»

    Web services represent an attractive technology for e-government applications, since they can be used to disseminate documents such as tax return forms, budget reports, regulatory laws, etc. In this paper, we consider the problem of serving such documents through Web services, with the goal of completing the user's request in minimum time (turnaround time). We propose a distributed peer-to-peer mi... View full abstract»

    Nowadays, many Web sites employ dynamic Web pages by accessing a back-end database and formatting the results into HTML pages. Performance is one of the issues that today's Web-enabled applications should deal with. Throughput, network bandwidth usage and user-perceived delay are some of the performance measures. Abandonment of Web sites increases if they fail in meeting performance requirements. ... View full abstract»

  • Enriching ebXML registries with OWL ontologies for efficient service discovery

    Web services, like their real life counterparts have several properties and thus truly useful semantic information can only be defined through standard ontology languages. Semantic Web is an important initiative in this respect. However, although service registries are the major mechanisms to discover services, the semantic support provided by service registries is completely detached from the sem... View full abstract»

  • THROWS: an architecture for highly available distributed execution of Web services compositions

    Web services emergence has triggered extensive research efforts. Currently, there is a trend towards deploying business processes as an orchestration of Web services compositions. Given that Web services are inherently loosely-coupled and are primarily built independently, they are most likely to have characteristics (e.g., transaction support, failure recovery, access policies) that might not be ...

  • An access control system for a Web map management service

    In this paper, we present an access control model for spatial data on Web. Such a model is based on the following assumptions: first, spatial data consist of objects with sharp boundaries located in a geographical space; second, data are manipulated through the operations provided by a Web map management service. The goal of the system is to control the way data are accessed by users having differ... View full abstract»

  • A constraint language approach to matchmaking

    The need to discover and select entities that match specified requirements arises in many contexts in distributed systems. Meeting this need is complicated by the fact that not only may the potential consumer specify constraints on resources, but the owner of the entity in question may specify constraints on the consumer. This observation has motivated Raman et al. to propose that discovery and se... View full abstract»

  • An MPEG-4 XMT scene structure algorithm for authentication and copyright protection

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (255 KB) | HTML iconHTML

    With the emerging technology of the MPEG-4 XMT standard, highly and efficiently compressed MPEG-4 scenes, which can include images, video, audio, and 3D objects, can be easily built using the text-based XMT format. XMT allows content authors to exchange their content with other authors, tools, or service providers and facilitates interoperability with MPEG-4, X3D and SMIL. In order for authors and...

    Many e-commerce and e-government applications are collaborative in nature (e.g. negotiation and e-catalog management). In collaborative environments, users typically define new document versions from any past version, which creates the need for supporting multiversion XML documents, particularly branched versioning. In this paper, we address the problem of evaluating path expression queries over X... View full abstract»

    Web services (WSs) correspond to conceptual entities with well defined interfaces published by different organizations. For example, with businesses, a WS might correspond to a business process to be invoked by other WSs and Internet applications. To increase availability of a WS, an organization might replicate it across different nodes. This study focuses on data intensive applications that: (a)... View full abstract»

  • A security-enhanced one-time payment scheme for credit card

    Traditional credit card payment is not secure as semi-secret credit card numbers are repetitively used. One-time transaction numbers have been recently proposed to enhance the security in credit card payment. Following this idea, we use a hash function in generation of one-time credit card numbers: the next one-time number is computed by hashing the current one-time number with a secret that is kn...

    Service oriented computing (SOC) demands an infrastructure that seamlessly integrates all connection points between business processes, services and associated support resources. Parts of the infrastructure may be supported by existing standards such as XACML and BPEL. However, an integral and sound framework that takes into account all these issues and serves as the formal underpinning of this in... View full abstract»

    BPEL4WS is a process modeling language for composing Web services. On the other hand, DAML-S is an ontology for defining semantic Web services that includes a process model. We present a one-way mapping from the DAML-S process model to BPEL4WS, focusing on their common aspect: providing a specification of a service's interaction protocol. The mapping clarifies their relation to each other, and ena... View full abstract»

    With the proliferation of Web technologies, the need to deliver services via the Web has increased tremendously. More and more, customers now demand one-stop service that calls for multiple services crossing organizational boundaries, which are required to be carefully and dynamically composed in a customized manner. Such a composition should not only select the most appropriate available service,... View full abstract»
