There is now widespread acceptance of Web services and service-oriented architectures. But despite the agreement on key Web services standards there remain many challenges. Programming environments based on WSDL support go some way to facilitating Web service development. However Web services fundamentally rely on XML and Schema, not on contemporary programming language type systems such as tho...

At present, there is a dichotomy of approaches to supporting web service implementation: extending mainstream programming languages with libraries and metadata notations vs. designing new languages. While the former approach has proven suitable for interconnecting services on a simple point-to-point fashion, it turns to be unsuitable for coding concurrent, multi-party, and interrelated interact...

Language offers human beings the ability to exchange information. Whether the information is understood or not depends on the structure, complexity and knowledge of the language. Language is designed for a certain context. In this paper, the context is Service Oriented Architectures. We present a query language for retrieving information about the resource consumption of services. The language ...

In this paper, the authors demonstrate that language diversity imposes a significant barrier in message communication like Short Messaging Service (SMS). SMS and other messaging services, including Multimedia Messaging Service (MMS) and e-mail, are widely used for person-to-person and Businessto-Consumer (B2C) communications due to their reach, simplicity and reliability of delivery. Reach and ...

The increasingly competitive environment pressures telecommunications service providers to reduce their concept-tomarket time. This time is influenced by a multitude of factors. For the benefit of telecom service designers, this paper focuses on increasing the degree of automation, offering team collaboration capabilities and bridging heterogeneous technologies. To address these factors, we pro...

Despite being trained in pre-service teacher education programs, most EFL teachers are underprepared when faced with language assessment-related activities. Part of the problem emanates from the fact that Language Assessment Literacy (LAL) as a construct has not been well defined by experts. The purpose of this study was to pinpoint the components of LAL in the Iranian EFL context using an adap...

Currently, Service-Oriented Architecture (SOA) is becoming the most popular software architecture of contemporary enterprise applications, and one crucial technique of its implementation is web services. Individual service offered by some service providers may symbolize limited business functionality; however, by composing individual services from different service providers, a composite servic...

We have built a database-driven e-service management system prototype called EsMS. The key idea is separating the management of e-service data from their visual representation. EsMS provides a template language EsHTML for specifying a web page’s representation. This language also serves as the language to compose and incorporate e-services from existing e-services, which might be provided by ot...

Models are central tools for modern scientists and decision makers, and there are many existing frameworks to support their creation, execution and composition. Many frameworks are based on proprietary interfaces, and do not lend themselves to the integration of models from diverse disciplines. Web based systems, or systems based on web services, such as Taverna and Kepler, allow composition of...
