The Universal Description, Discovery and Integration (UDDI) registry is widely used for organizing Web services in the Internet, but it cannot meet the requirement of organizing massive Web services in the cloud computing environment. In this paper, a Web service registration cloud based on structured P2P and semantics (PSSRC) is presented. On the one hand, PSSRC works on a structured P2P overlay which is organized by using Pastry in multiple registration nodes, where each registration node is composed of seven modules namely system configuration, schedule and distribution, P2P communication, access and control, UDDI, resources monitoring, and semantic process. On the other hand, a semantic ontology database named WordNet is used to process semantic queries in PSSRC. PSSRC inherits the advantage of UDDI in that the registration and discovery of Web services are transparent to Web services providers. Furthermore, it is shown by experiment that the capacity of PSSRC can be extended dynamically, and both semantic queries and large scalable accesses are well supported.

Service Reuse

Web services retrieval is a critical step for reusing existing services in the SOA paradigm. In the UDDI registry, traditional category-based approaches have been used to locate candidate services. However, these approaches usually achieve relatively low precision because some candidate Web Services in the result set cannot provide actually suitable operations for users. In this article, we present a new approach to improve this kind of category-based Web Services retrieval process that can refine the coarse matching results step by step. The refinement is based on the idea that operation specification is very important to service reuse. Therefore, a Web Service is investigated via multiple instances view in our approach, which indicates that a service is labeled as positive if and only if at least one operation provided by this service is usable to the user. Otherwise, it is labeled as negative. Experimental results demonstrate that our approach can increase the retrieval precision to a certain extent after one or two rounds of refinement.

Uddi Registry

Software is gradually becoming more built by composing web services to support enterprise applications integration; thus, making the process of composing web services a significant topic. The Quality of Service (QoS) in web service composition plays a crucial role. As such, it is important to guarantee, monitor, and enforce QoS and ability to handle failures during execution. Therefore, an urgent need exists for a dynamic Web Service Composition and Execution (WSCE) framework based on QoS constraints. A WSCE broker is designed to maintain the following function: intelligent web service selection decisions based on local QoS for individual web service or global QoS based selection for composed web services, execution tracking, and adaptation. A QoS certifier controlled by the UDDI registry is proposed to verify the claimed QoS attributes. The authors evaluate the composition plan along with performance time analysis.

Definition Of

Portals went through the following different life cycle stages: desktop organization and personalization; single intranet-based portals such as human resource and Internet product-based or industry-based portals; functional-based portals such as knowledge management and business intelligence; and integrated intranet-based enterprise portal (EP) covering some or all functions of the enterprise (see for example http://www.ebizq.net/topics/eai/features/1650. html on how integrating portals and business process management (BPM) enabled the presentation of an integrated view of diverse back-end databases). Current research and practice efforts are directed toward making portals an open system supporting different platforms and allowing its integration into emerging technologies such as Web services (WS). A WS, on the other hand, is defined as an integrating loosely coupled application that uses three major standards: WSDL (definition of WS), UDDI (registry and discovery of WS), and SOAP (access of a WS). However, strongly coupled applications may also benefit from WS technologies to componentized diverse application platforms (i.e., databases, file-based legacy systems) using WS technologies. The article emphasizes cross-organization integration of business function and processes, rather than simply accessing general purpose WS such as weather forecasts and currency conversion.

Discovery And Integration

This paper presents a research initiative, which aims at developing replication mechanisms for the dynamic management of the content of several Universal Description, Discovery, and Integration (UDDI) registries (Curbera et al., 2003). These replication mechanisms are intended to be deployed in an environment of Web services (Papazoglou & Georgakopoulos, 2003). By content of an UDDI registry, we mean the announcements of Web services that providers post on the UDDI registry.
