The widespread of Web services in the ubiquitous computing era and the impossibility to predict a priori all possible user needs generates the necessity for on-demand service composition. Natural language is one of the the easiest ways for a user to express what he expects regarding a service. Two main problems need to be solved in order to create a composite service to satisfy the user: a)retr...

In the last years, multimedia applications have been evolving and taking an important role in the multi-domain information exchange on the Internet. Although the QoS parameters required by the multimedia applications are well known and some form of guaranteed QoS is available at transport and network layers, there is no standard QoS specification enabling to deploy the underlying mechanisms in ...

There is a recent interest in integrating the serviceand aspect-oriented software development paradigms. However, most of the approaches proposed thus far rely on a non-service based aspect model that severely restricts the language choices either for implementing the service-oriented applications, the aspects, or both. This paper presents a unified development model for serviceand aspect-orien...

With the advent of web services standards and a service-oriented Grid architecture, it is foreseeable that competing as well as complimenting computational services will proliferate. Current efforts in standardising service interface focuses on how one can execute these services in terms of their syntactic descriptions. Their capabilities and relations with other service types are only articula...

patient satisfaction is one of the sensitive indicators in determining the effectiveness of service rendered in hospitals. the study focus on comparing the health care services of  two cardiology based corporate hospitals in hyderabad, andhra pradesh, india. the data for the study was collected through a questionnaire consisting of two sections. an attempt has been made to elicit the informatio...

The service-based computing paradigm is rapidly gaining ground as a viable choice for the design of modern software applications. In this paper, we review the basic operation of software components and the necessary infrastructure in the service-based paradigm, and identify the core set of requirements that those components and infrastructure have to satisfy. We argue that these requirements ne...

Complexity issues and the requirements on semantic web application in the Life Science domains recently motivated a few works on stateless service description languages [1, 5]. With stateless services, it is possible to reason about the semantic relationships between inputs and outputs, while keeping matchmaking and composition decidable. In this paper we extend the languages introduced in [1] ...

In the Language Grid, automatically composing Web services is a crucial task. This task involves vertical and horizontal composition. Vertical composition consists of defining an appropriate combination of simple processes to perform a composition task. Horizontal composition consists of determining the most appropriate Web service from among a set of functionally equivalent ones for each compo...

Open distributed systems are computing systems that can be characterized by a heterogeneity of involved machine-and network architectures as well as of the data processed. They have to be able to integrate existing applications, to cope with the use of multiple programming-languages, and potentially high dynamics by joining and leaving components. The coordination language Laura is designed to ...

Return on Investment (ROI) analysis plays a primary role in business strategic planning; however it is not such a straightforward process in itself. From the perspective of a Language Service Provider’s (LSP) case study, an economic impact analysis of machine translation (MT) technology usage is required. Potential initial development and customization costs are investigated, as well as estimat...
