Abstract

The amount of structured information published on the World Wide Web is huge and steadily increases. The demand for uniform management of these heterogeneous and autonomous sources is also increasing. In this paper we present a method which is capable of virtually integrating data sources with logical rules into a catalogue and more importantly, discovering similar entities across the information sources. We prove that the technique is algorithmically decidable. The resulting system is primarily suitable for applications which require an integrated view of all the distributed database components for querying only, such as web shops.
