With the exploding of Internet information, semantic technologies are proposed to help people find what they want. Semantic search requires domain-oriented ontology and user-defined workflow to process online data. Mostly, semantic search are focus on user query optimization. The semantic of online data is usually considered less than the domain ontology to processing query, and the search targets...
Due to some reasons, quite a lot of Web services are running inside private networks behind network address translators (NATs), which makes it difficult for consumers to directly access the services. In this article we propose an indirect method for accessing Web services behind NATs.
With loosely coupled Web services, service-oriented applications and processes could be composite and dynamic and change service providers based on the criteria such as price, reliability, security, credit, or the elements' weighted utilities. A precise service search engine is critical for the loosely coupled applications to select emerging Web services regularly, automatically, across the Internet...
Summary form only given. Service-oriented computing (SOC) is considered as a new computing paradigm after the object-oriented computing paradigm. It utilizes services as fundamental elements for applications/solutions. Services are autonomous platform-independent computational elements that can be described, published, discovered, orchestrated and programmed using XML for the purpose of developing...
Transaction commit protocols have widely been used to ensure the correctness and reliability of distributed applications. This paper investigates into the performance of such protocols within the context of composite Web services. It presents a new commit protocol which aims to improve the performance of composite Web services transactions. The proposed protocol is tested through various analytical...

With the advent of service-oriented architecture (SOA), these enterprises are exploring the development of business integration solutions based on SOA. A service is defined as a particular business or IT function that is accessible by independent...
