Towards Dynamic Web Service Generation on Demand

The web services technology enables communication, distributed computation and interoperability in heterogeneous environments. Although the technology is well specified and supported by the programming tools, it is still not widely used. Some of the main reasons are the difficulties which the end users have in searching an adequate web service to get the required data. Even if found, the web service rarely fit the exact needs. This paper presents a new framework for dynamical generation of the web services from the heterogeneous data sources on user's demand. The aim of the framework is to generate web services that are customized to the particular requirements. Apart from specifying the requirements in WSDL, the framework proposes the ontology for describing the available data.
