Web service composition enables the provision/reusing of existing services in different business processes to satisfy different business requirements without investing in new infrastructure. QoS-aware web service composition seeks to help users find the optimal solution with maximization of users' satisfaction. A number of approaches based on Communicating Sequential Processes (CSP) have been proposed to model and verify properties of web service composition. However, little work has been done in verifying inputs, outputs and QoS criteria of web service composition. In this paper, we present a framework to model and verify QoS-aware web service composition by Timed CSP. It helps verify whether the service composition can accept inputs, generate outputs, and meet QoS requirements as specified. To do the verification, transformation rules that map QoS-aware web service composition to Timed CSP are defined. In order to explain the framework and transformation rules, we design a case study, where the model of QoSaware web service composition is transformed to the model of process composition in Timed CSP and the program in machine-readable CSP (CSPM). Furthermore, experiments are performed by using the Failure Divergence Refinement (FDR) tool to verify inputs, outputs, and QoS of the service composition.

“…The mapping of choreography languages onto formal techniques is often less complete than in the case of orchestration. Similarly to WS-BPEL, it is also possible to identify many approaches that use WS-CDL as source language and map it onto CSP [21], Prioritized Time Petri Net [22], Timed Automata [23] [24] and Spatial-Temporal Logic [25]. These approaches differ in terms of the WS-CDL constructs subset that is actually considered in the mapping.…”

“…Most of these approaches formalize only the WS-CDL basic elements (i.e., basic and control flow activities, and work units). For example, the mapping of work unit, parallel, assigning, choice and sequence is considered in [21]. Some approaches support more complete formalization (i.e., including exception and compensation handling mechanism) in a mapping to CSP [26].…”

Service-Oriented Computing (SOC) was introduced some years ago as a paradigm that allows companies to expose their core competencies as services. Yet, we can only benefit from the full potential of SOC if we explore the possibility of composing services. In practice, service composition enables the development of complex systems by combining existing services, which makes it possible to integrate business processes across different companies. Several languages have been defined to specify service compositions, such as WS-BPEL and WS-CDL. However, these languages lack formal semantics, so that they do not allow the verification of the service composition behavior by means of properties such as the absence of deadlocks and livelocks. In this paper, we present a structured survey on initiatives in which formal description techniques were applied to specify and possibly verify service compositions. As a result of this study, we identified some open challenges and some topics for future work.

“…The word processing techniques learners of CAT technology in translation class must acquire mainly include advanced searching & replacing, automatic generation of catalog & index, cross reference, macro, revision of marked documents, automatic sequence and so on. [13] Digital text accessing skills: Using CAT system requires having the electronic document in the source language before the process of translation. However, a great number of documents to be translated are presented in hard copy to translators in reality.…”

Abstract-this paper aims to advocate the application of CAT technology in the traditional translation teaching class in universities. Based on the introduction of the development of CAT technology and its wide application in modern translation industry, the necessity of applying CAT technology in translation teaching is convincingly proven, which is followed by an elaboration on the design of CAT teaching modules and the construction of CAT teaching system. At the end of this paper, the practice of enhancing the traditional translation curriculum with reference to application of CAT technology is clearly demonstrated so as to set an empirical example to those colleges and universities who'd like to follow suits.
