Conceptualising a domain has long been recognised as a prerequisite for understanding that domain and processing information about it. Ontologies are explicit specifications of conceptualisations which are now recognised as important components of information systems and information processing. In this paper, we describe a project in which ontologies are(More)
Combinatorial worlds can be used to give an account of necessity and possibility. Both accessibility and similarity between worlds can be deened. In this paper, we claim that combinatorial worlds can form a knowledge representation framework, and provide an interesting approach to nonmonotonic reasoning and belief revision. We investigate such aspects of(More)
This paper suggests that agents should be seen as processes (occurrents) rather than objects (continuants), and attempts to analyse the consequences of this view. Aspects of process ontology are presented and claims are made that process ontology facilitates understanding agents. The focus is on communication rather than contents (ontologies), but the(More)
In this paper we extend the framework of combinatorial and conceptual worlds to allow arbitrary relations. Conceptual worlds of properties provide a framework for knowledge representation, reasoning, and in particular for conceptual belief revision. However, it is desirable to consider such worlds where relations are not restricted to properties. Firstly,(More)
