Wrapping Legacy Code for a Service Oriented Knowledge Discovery Support System

A Knowledge Discovery Support System (KDSS) is a complete, integrated environment providing a number of facilities to effectively design a process of Knowledge Discovery in Databases (KDD). The recent shift towards network organizations, and the dynamism of the KDD field, where new algorithms and techniques are developed continuously, lead to the design of open, modular and flexible service oriented KDSS. In this paper, we briefly present the architecture of the Service Oriented KDSS under development at the Università Politecnica delle Marche, and we introduce a wrapping service which is devoted to the automatic creation of specific wrappers encapsulating KDD tools, so that they can be viewed and exploited as services. In this way, new KDD tools, developed by third party and available on the Web, can be easily added to the KDSS, making it a truly open and extensible environment.
