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 ot…

The design of intelligent agents is greatly influenced by the many different models that exist to represent knowledge. It is essential that such agents have computationally adequate mechanisms to manage its knowledge, which more often than not is incomplete and/or…

Focusing on the Ontology Change problem, we consider an environment where Description Logics (DLs) are the logical formalization to express knowledge bases, and the integration of distributed ontologies is developed under new extensions and modifications of the Belief Revision theories…

The reform of Spanish University System occurs for allow that the universities to board the needs derived from the new kinds of knowledge generation and transmission. The university’s objective is the formation of professionals capable of taking, analysing and elaborating…

In this paper, we build on previous work on Belief Revision operators based on the use of logic programming with Answer Set semantics as a representation language. We present a set of postulates for Answer Set Revision with respect to…

The use of clocks for timekeeping seems to be a straightforward and almost intuitive routine. Glancing at mechanical clocks designed in Edo period Japan, however, we witness how modern-day intuitions betray our attempts to understand devices created in a culture…

This project investigates how doctoral students make
‘learning leaps’ to recognise and cross conceptual
and skills thresholds in their research and ways in
which they can be best supported to do so. It
responds to current national and international
concerns…

The goal of this work involves the developing of an argumentation-based formalism that an agent could use for constructing plans. In this formalism, agents will have certain knowledge about the world, and a set of actions that they will be…

The supervision of postgraduate Master's Degree dissertations has attracted little attention in the
academic literature and is an under researched area of supervisory activity. This research was a
response to generate new knowledge concerning the praxis of supervisors who supervise…
