The development of Knowledge Discovery in Databases (KDD) projects in collaborative and distributed environments requires facilities to search for, choose, set-up, compose and execute suitable data manipulation tools. This implies the necessity to explicitly represent and annotate different kinds of information about tools, data and their characteristics. In this framework, we are developing a serviceoriented support platform called Knowledge Discovery in Databases Virtual Mart. In this paper we discuss the design and implementation of the UDDI service broker, a core element of the platform. We analyze the information needed to describe a tool in our platform, showing limitations of the present UDDI standard. Then, we present our solution to overcome such limitations and to extend UDDI broker capabilities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
