Description
Summary:In a Web services (WS) composition process, identifying the relevant sequence of services that meets the end user requirements remains an important issue. WS semantic enrichment process helps in solving this issue to cope with data heterogeneity, and facilitate their discovery and integration. This process should support personalization that takes into account user context. Currently, this personalization is not sufficient. In fact, it needs to be extended until the realization step. Besides, it requires many human interventions. The main characteristics of services based architecture, which are deployment and distribution, may open important security flaws. Personalization should then include protection against threats that could be encountered. WS composition must be made in a careful way, and security integration is neccesary.Starting from the beginning of runtime phase of a composition process, this paper suggests an on-the-fly approach which aims to: 1) Personalize the scheduling of all linked semantic Web services (SWS) according to their relevance degree based on user context ontology. 2) Try to improve the security level of each SWS and their composition according to usage and based on a security ontology and security patterns.
