Software solutions to automate the procurement of web services are gaining importance when technology evolves, the number of providers increases and the needs of the clients become more complex. There are several proposals in this field, but they all have important drawbacks, namely: many of them are not able to check offers and demands for internal consistency; selecting the best offer usually relies on evaluating linear objective functions, which is quite a naive solution; the language to express offers is usually less expressive than the language to express demands; and, last but not least, providers cannot impose constraints on their clients. In this article, we present a solution to overcome these problems that relies on constraint programming; furthermore, we present a run-time framework, some experimental results, and a comparison with other proposals.

Web service is becoming an important area of business processing and research for enterprise systems. Various Web service providers currently offer diverse computing services ranging from entertainment, finance, and health care to real-time application. With the widespread proliferation of Web Services, not only delivering secure services has become a critical challenge for the service providers, but users face constant challenges in selecting the appropriate Web services for their enterprise application systems. Security has become an important issue for information systems (IS) managers for a secure integration of Web services with their enterprise systems. Security is one of the determining factors in selecting appropriate Web services. The need for run-time composition of enterprise systems with third-party Web services requires a careful selection process of Web services with security assurances consistent with the enterprise business goal. Selection of appropriate Web services with required security assurances is essentially a problem of choice among several alternative services available in the market. The IS managers have little control of the actual security behavior of the third-party Web services, however, they can control the selection of right services which could likely comply their security requirements. Selecting third-party Web services arbitrarily over the Internet is critical as well as risky.

Offering public access to efficient transactional stock market functionalities is of interest to all banks and bank users. Traditional service oriented architecture (SOA) technology succeeds at providing reasonable, good Web-based brokerage solutions, but may lack extensibility possibilities. By introducing Semantic Web Services (SWS) as a way to integrate third party services from distributed service providers, we propose in this chapter an innovative way to offer online real-time solutions that are easy-to-use for customers. The combined use of ontologies and SWS allows different users to define their own portfolio management strategies regardless of the information provider. In deed the semantic layer is a powerful way to integrate the information of many providers in an easy way. With due regard for more development of security technological issues, research on SWS has shown that the deployment of the technology in commercial solutions is within sight.

Purpose Semantic categorization of Web services comprises a fundamental requirement for enabling more efficient and accurate search and discovery of services in the semantic Web era. However, to efficiently deal with the growing presence of Web services, more automated mechanisms are required. This paper aims to introduce an automatic Web service categorization mechanism, by exploiting various techniques that aim to increase the overall prediction accuracy. Design/methodology/approach The paper proposes the use of Error Correcting Output Codes on top of a Logistic Model Trees-based classifier, in conjunction with a data pre-processing technique that reduces the original feature-space dimension without affecting data integrity. The proposed technique is generalized so as to adhere to all Web services with a description file. A semantic matchmaking scheme is also proposed for enabling the semantic annotation of the input and output parameters of each operation. Findings The proposed Web service categorization framework was tested with the OWLS-TC v4.0, as well as a synthetic data set with a systematic evaluation procedure that enables comparison with well-known approaches. After conducting exhaustive evaluation experiments, categorization efficiency in terms of accuracy, precision, recall and F-measure was measured. The presented Web service categorization framework outperformed the other benchmark techniques, which comprise different variations of it and also third-party implementations. Originality/value The proposed three-level categorization approach is a significant contribution to the Web service community, as it allows the automatic semantic categorization of all functional elements of Web services that are equipped with a service description file.

The Internet and emerging technologies are facilitating the creation of new marketplaces designed to address a diverse range of business and societal needs. As companies are utilizing technology to manage their business processes, such a marketplace has emerged that is designed to provide third-party availability of business services delivered via Web services technology, particularly in the context of Cloud Computing. The Web Services Marketplace creates a common trading ground wherein buyers and sellers of business services can come together within a centralized marketplace. However, sellers of business services must provide a mechanism by which knowledge and awareness of the service is created for the buyer and a means by which sellers can effectively compete in the marketplace. The most widely accepted method for accomplishing these tasks is advertising. This study investigates the nascent phenomenon of the advertising of business services within the Web services marketplace, develops a theoretically grounded definition and characteristics of business services offered in the Web Services Marketplace, and develops a model for the effective advertisement of business services offered in the Web Services Marketplace.

The Way

This article presents an alternate approach to effectively address the way privacy agreements are initiated through web services. In this new framework, the consumer and the service provider can mutually negotiate on the privacy terms. It contains a privacy model in which the transaction takes place after a negotiation between the service provider and the web user is completed. In addition, this framework would support various negotiation levels of the agreement lifecycle which is an important aspect of the dynamic environment of a B2C e-commerce scenario. A third party trusted agency and a privacy filter are included to handle privacy information of the web user. The author seeks to raise awareness of the issues surrounding privacy transactions and the potential ongoing impact to both service providers and clients as the use of web services accelerates.
