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...

Web services have been developed and deployed for GIS applications. Client-server interaction in such applications is limited by the service provider, such as ArcWeb Service. This paper will discuss the needs from service requester which lead to the exploration on the design and manipulation of Web Service interface. It is likely that GIS Web Service promotes the separation of spatial feature a...

Web service, as an emerging technology, is being more and more widely adopted on the Internet for electronic business. The emergence of web service greatly facilitates business process management and reengineering. This paper develops a conceptual architecture for workflow management system based on web service infrastructure. The proposed architecture fully explores the benefits offered by web...

web hosting service, web server cluster, load balancing, scalability, super linear speedup, performance analysis FLEX is a new cost effective, "locality aware" load balancing solution for a shared web hosting service implemented on a cluster of machines [C99]. FLEX allocates hosted web sites to different machines in the cluster based on the sites' processing and memory requirements which are es...

The paper mentioned using SOA framework and the technology of Web Service, aiming at the problem of "Information Isolated Island", specifically for rural information resources, an agricultural information service platform is constructed based on SOA and Web Service. This platform integrates distributed systems and service platforms and it deals with agricultural information by cooperative proce...

The boom of Service oriented architecture is on substantial rise. SOA developers orchestrate individual SOA objects into web services. It has been a dream of software engineers to promote and innovate the concept of software reusability. Providing and using services dynamically over web is increasingly becoming times demand towards promoting software reuse in real sense. Probably the most impor...

By definition, web-services composition works on developing merely optimum coordination among a number of available web-services to provide a new composed web-service intended to satisfy some users requirements for which a single web service is not (good) enough. In this article, the formulation of the automatic web-services composition is proposed as several set-cover problems and an approxima...

This paper introduces and evaluates a novel Web service interface annotation and matching scheme designed for processing large sets of Web service interface descriptions. The matching scheme relies on a set of rules, which exploit the structural relationships encoded in an automatically learned ontology to discover matching interface elements. The proposed scheme is evaluated on a Web services ...

In recent years, with the rapid development of satellite remote sensing technology, the obtainable remote sensing data has been increasing at striking rate. However, because of heterogeneous storage, resources of different stations and domains can’t be operated mutually and shared. Integration of semantic WEB service and remote sensing information processing can help to solve these problems. On...
