The papers in this volume are extended versions of
presentations at the fourth International Conference on
Information Processing and Management of Uncertainty in
Knowledge-based Systems (IPMU), held in Palma de Mallorca,
July 6-10, 1992.
The conference focused on issues related to the acquisition,
representation, management, and transmission of information
in knowledge-based and decision-making systems. The book is
focused on methodologies related to artificial intelligence,
including both theoretical and applied papers.
The first section of the book is devoted to non-monotonic
reasoning and the managementof default knowledge. The
second section deals with methods using non-classical logics
to deal with imperfect knowledge and to represent its
spatial and temporal components. The third section presents
various methods for the acquisition of uncertain and
imprecise knowledge. The fourthsection is concerned with
the use of qualitative, uncertain, temporal, and ambiguous
pieces of information in knowledge-based systems, expert
systems, and process controllers. The last section contains
papers using artificial neural network methodologies.
