Classical methods for representing and reasoning with knowledge rely on the assumption that the available information is complete, certain and consistent. In real-world problems this is usually not the case, and Al has long dealt with the issue of finding…

This study investigates an approach of knowledge discovery and data mining in insufficient databases. An application of Computational Taxonomy analysis demonstrates that the approach is effective in such a data mining process. The approach is characterized by the use of…

We examine a knowledge representation architecture to support context interchange
mediation. For autonomous receivers and sources sharing a common subject domain,
the mediator's reasoning engine can devise query plans integrating multiple sources and
resolving semantic heterogeneity. Receiver…

Innovation implies managing knowledge in a creative way in order to respond to the requests coming from the market and to other social needs. Communication and human interaction contribute a lot in this direction. Innovation provides a great challenge for…

Abstract:
The increased volume and complexity of information available via the Internet and other networked information and communications systems (ICTs) have heightened the need for more efficient and effective ways of searching on-line resources. Technologies involving automated and human-operated software…

Array processing techniques such as beamforming or matched field processing require accurate knowledge of the location of individual elements in the array. For horizontal arrays laid on the ocean floor, relative arrival times measured across the array from nearby implosive…
