Web services, each of which consists of a set of functions to do certain activities, would allow organizations to do their businesses easier by concentrating on the business logic and reusing existing web services. In order to realize that vision, we need a language to specify, compose and implement web services in such a way that they can be shared and reused by different users on the Internet...

In response to the International Journal of Health Policy and Management (IJHPM)editorial, this commentary adds to the debate about ethical dimensions of compassionate care in UK service provision. It acknowledges the importance of the original paper, and attempts to explore some of the issues that are raised in the context of nursing practice, research and education. It is argued that each of ...

In Internet telephony, end systems can take a much larger role in providing services than in traditional telephony systems. We analyze the importance of end system services and describe the services and the Service Logic Execution Environment (SLEE) implemented in our SIP user agent, SIPC. Since we believe that end system services differ in their requirements from network services, we define a ...

The generalization of Internet continues to grow unabated, especially with the rapid adoption of the mobile and fixed wireless connecting a myriad of devices at homes and businesses. It allows us to have more and more services at low costs. In the future, anyone with any kind of devices at any times will have options to access any service from anywhere. In fulfilling this requirement, more rapi...

The Service oriented architecture Modeling Language (SoaML) is a new specification from the Object Management Group (OMG) that provides support for modelling services. The SoaML specification defines three different approaches to specifying services; simple interfaces, service interfaces and service contracts. In this paper we provide an overview of the SoaML language constructs and discuss the...

The plethora of web services available on the World Wide Web presents a great opportunity to users. It also gives rises to a great challenge: to enable discovery, reuse and interoperation of web services and software components on the web. To support programmatic service discovery, we have developed a suite of methods that utilize both the semantics of natural language descriptions and identifi...

We present a web service for natural language parsing, prediction, generation, and translation using grammars in Portable Grammar Format (PGF), the target format of the Grammatical Framework (GF) grammar compiler. The web service implementation is open source, works with any PGF grammar, and with any web server that supports FastCGI. The service exposes a simple interface which makes it possibl...

One of the most serious challenges that web-service enabled e-marketplaces face is the lack of formal support for expressing service requests against UDDI-resident web-services in order to solve a complex business problem. In this paper we present a web-service request language (XSRL) developed on the basis of AI planning and the XML database query language XQuery. This framework is designed to...

This paper introduces a programming language for serviceoriented agents. Jadl++ combines the ease of use of scripting-languages with a state-of-the-art service oriented approach which allows the seamless integration of web-services. Furthermore, the language includes OWLbased ontologies for semantic descriptions of data and services, thus allowing agents to make intelligent decisions about serv...
