Despite the evident benefits of semantic Web services, their widespread adoption by the industry is hindered by practicality issues. We see great promise in using proven Web 2.0 techniques to enable semantic Web services technologies to rise to their potential. We propose the social service network (SSN) - a framework integrating Web 2.0 social aspects to automatically enrich Web services with semantic...
This paper describes essential service and ontology design considerations for a multi-agent system. We will establish a context of basic information sharing and discovery for a combat search and rescue vignette. FIPA protocols and the OWL-S Task Model will be presented along with the associated work flow processes for our range of service options. A Protege-based ontology will convey our semantic...
It is accepted that domain based development is playing an important role on IT projects today. Following such idea, this paper presents preliminary study results of a prototype architecture created with the purpose of using a domain-driven approach to shorten the development of software projects. Our discussion presents a way of sharing business domain models, developed in different project sites,...
Some of the characteristics that make service-oriented architectures appealing for enterprise applications also make them vulnerable to security breaches. The vulnerabilities are primarily due to the openness of the service-execution environment, to the dynamic run-time selection and composition of services, and to the autonomy of the individual services. In this paper, we describe these vulnerabilities...
Creating a service-oriented architecture requires the identification of services to be composed together in order to solve a given need. Currently, software engineers perform this design task by hand by identifying services and how to compose them. In this paper, we propose RuGCo a system to automatically compose Web services coming from a static large repository, according to a domain ontology expressed...
In this paper, we recognize the shortcomings of the current search engines that do not index and search the deep Web. We present requirements of a deep Web service search engine, that will lead to the query objects in the deep data sources. In order to realize the DWS search engine, we propose semantic metadata and annotation of deep Web services (DWS), a reasoning component to assess the relevance...
One of the challenges in SOA is to provide an efficient and effective way to select compatible Web service(s) and compose them into a functional service process that satisfies a user's needs. Moreover, the Web services(s) selected may be integrated with structures such as branches and merges to fulfill a task. This paper describes our system architecture and strategies on Web services composition...
The distribution of services spanning across organizational boundaries raises problems related to intellectual value that are less explored in current service oriented research. Being a way to manage the intellectual rights between service consumers and service providers, licenses are critical to be considered in services. A service license describes the terms and conditions for the use and access...
Web service is essential in achieving dynamic business process. With the dramatically increased number of Web services advertised in UDDI, Web Portal or Internet, how to locate the best Web service according to a user's requirement is becoming more and more important, which calls for efficient and effective Web service discovery mechanism. Considerable efforts have been attained in solving this problem...
Semantic Web service composition is about finding services from a repository that are able to accomplish a specified task. The task is defined in a form of a composition request which contains a set of available input parameters and a set of wanted output parameters. Instead of the parameter values, concepts from an ontology describing their semantics are passed to the composition engine. The composer...
The goal of the Web Service Composition (WSC) problem is to find an optimal "composition" of web services to satisfy a given request using their syntactic and/or semantic features, when no single service satisfies it. In this paper, in particular, we study the WSC problem from semantic aspects, exploiting the supertype-subtype relationship among parameters, and propose a novel solutionbased...
As SOC and Web service technology become more widely used, large amounts of services need to be efficiently and effectively composed to meet complex businesses. In this paper, we proposed an approach to resolve the composition problem over large-scale services. We used an inverted table as index for a quick service discovery, and applied a service dependency graph (SDG) and an AND/OR graph as the...
Approaches to Web service composition are dependent upon some form of repository to hold service descriptions. Most service composition software relies upon highly-optimized and proprietary formats for representing service descriptions and storing them into a repository. Unlike these approaches, this paper reports on the development and evolution of a standards-based service description repository...
In this paper, we propose a Web service composition framework that uses Integer Linear Programming with non-functional objectives and constraints, in addition to the syntactic matching of Web services features. We envision that when Web services are fully deployed and commercialized in the near future, the criteria of Web service composition to achieve objectives will vary depending on users' needs...
Many automatic Web service composition algorithms based on AI planning techniques have been proposed. In this paper, we model the semantic Web service composition problem using a kind of simplified planning graph. It provides a unique search space, and can find a solution in polynomial time, but with possible redundant Web services.
The capabilities of organizations can be openly exposed, easily searched and discovered, and made readily-accessible to humans and particularly to machines, using service-oriented computing approaches. Artificial intelligence and software engineering researchers alike are tantalized by the promise of ubiquitously discovering and incorporating services into their own business processes (i.e. composition...
The following topics are dealt with: enterprise computing; e-commerce privacy and security; e-service; resource management; media management; business collaboration and semantic Web service composition.
Today, most approaches for inter-organizational business processes start bottom-up from the interfaces and the workflows of each partner described on the IT layer. Alternatively, one may start from the commitments and agreements between business partners to reach their complementary business goals. The latter approach is target of the UN/CEFACT Modeling Methodology (UMM), which models a global choreography...
The collaboration landscape evolves rapidly by allowing people to participate in ad-hoc and process-centric collaborations. Thus, it is important to support humans in managing highly dynamic and complex interactions. The problem currently with managing interactions is that humans are unable to specify different interaction interfaces for various collaborations, nor able to indicate their availability...
WSDL Web services are built around the request-reply framework, requiring service invocation to be bundled together with all relevant data in a single message. Inefficiency becomes evident as Web service providers begin to offer more robust services that require massive datasets (e.g., multimedia and scientific data). Under the WSDL standards, these hefty datasets must be ported to an appropriate...
