Towards Semi-automated Workflow-Based Aggregation of Web Services

چکیده
Abstract. Service aggregation is one of the main issues in the emerging area of service-oriented computing. The aim of this paper is to contribute to the long-term objective of lifting service aggregation from manual hand-crafting to a semi-automated engineered process. We present a methodology which, given a set of service contracts, tries to construct an aggregation of such services. Service contracts include a description of the service behaviour (expressed by a YAWL workflow), as well as an (ontology-annotated) signature. The core aggregation process basically performs a control-flow and an (ontology-aware) data-flow analysis of a set of YAWL workflows to build the contract of an aggregated service.

Architectural Plan for Constructing Fault Tolerable Workflow Engines Based on Grid Service
In this paper the design and implementation of fault tolerable architecture for scientific workflow engines is presented. The engines are assumed to be implemented as composite web services. Current architectures for workflow engines do not make any considerations for substituting faulty web services with correct ones at run time. The difficulty is to rollback the execution state of the workflo...

متن کاملTowards Ontology-based QoS Aggregation for Composite Web Services
Determining the QoS (quality of service) of composite Web services is of crucial importance for both service providers and consumers. However, service descriptions of constituent services are often heterogeneous which makes the aggregation of multiple single-service QoS difficult. In this paper, we address the heterogeneity problem from the perspective of knowledge engineering. We propose a QoS...
متن کاملImage flip CAPTCHA
The massive and automated access to Web resources through robots has made it essential for Web service providers to make some conclusion about whether the "user" is a human or a robot. A Human Interaction Proof (HIP) like Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) offers a way to make such a distinction. CAPTCHA is a reverse Turing test used by Web serv...
متن کاملTowards Automated Verification of Web Services
This paper proposes the use of model-checking software technology for the verification of workflows and business processes behaviour based on web services, namely the use of the SPIN model checker. Since the specification of a business process behaviour based on web services can be decomposed into patterns, it is proposed a translation of a well known collection of workflow patterns into PROMEL...
