Non-functional parameters and automatic generation and publishing for Web service description improvement

Abstract

The concept of intention is usually addressed only from a service user side. Moreover, the concepts of context and Quality of Service (QoS) are not attributed great importance in the various stages of a Web service life cycle. Consequently, this lack of information in service descriptions leads to a significant semantic loss, which negatively affects the accuracy of their discovery. In order to overcome these problems, we proposed to integrate these nonfunctional properties (context, QoS and intention) within the Web Service descriptions. To automatically generate and publish these descriptions, we propose in this paper a framework called Adaptable Intentional Web Service-Publishing Framework. This framework semantically annotates the OWL-S description by nonfunctional properties. Moreover, we ensure the semantic annotation through an automatic detection method of service intention developed using Natural Language Processing techniques. As for the publication task, we extended the UDDI register so that it encompasses intentional, contextual and QoS information.
