Abstract

Web services enable the user to integrate and manipulate data from distributed data sources without worrying about the underlying syntactical details. We describe extensions to the view integration approach to support dynamic integration of data from web services and support dynamic composition of web services from existing web services. In particular, we describe techniques to extend the “inverse rules” query reformulation algorithm to generate a universal integration plan to answer user queries. To demonstrate the effectiveness of these techniques we describe a mediator-based system that dynamically integrates various web services in response to a user query and provides a integrated web service that can handle a range of user queries.
