Nonmonotonic reasoning is context-dependent [1]. For instance, Reiterstyle defaults capture patterns of inference of the form “in the absence of information to the contrary conclude” [2]. Thus, conclusions are tentative, and they may become retracted in view of further information (or changing contexts). In other words, conclusions are context-dependent and contexts change over time. Unlike thi...

An enquiry into the role of ontologies and analogous thinking in the design support

In this paper we extend the concept of exception spaces as defined by Cost and Salzberg (Cost and Salzberg, 1993), in the context of exemplar-based reasoning. Cost et al. defined exception spaces based on the goodness, in terms of performance, of an exemplar. While this is straightforward when using exemplars for classification problems, such a definition does not exist for regression problems....

Innovative query interfaces to knowledge and database systems must go beyond simply returning the requested information. They must be capable of producing intentional answers when a description improves the understanding of an answer [Mot94], producing conditional answers when no one answer matches the conditions of a query, and using ontological information in processing a query. They should b...
