Traditionally, qualitative simulation uses a global, state-based representation to describe the behavior of the modeled system. For larger, more complex systems this representatio...
Existing approaches to knowledge representation and reasoning in the context of open systems either deal with "objective" knowledge or with beliefs. In contrast, there ha...
Answering queries posed over knowledge bases is a central problem in knowledge representation and database theory. In databases, query containment is one of the important query op...
This paper describes a computational model of similarity developed to support analogical software reuse. Similarity is computed from conceptual descriptions of software artifacts o...
Many of the difficulties users experience when working with interactive systems arise from misfits between the user's conceptualisation of the domain and device with which the...
