Pruning Ontologies in the Development of Conceptual Schemas of Information Systemstexts. Our method is general and it can be adapted to most conceptual modeling languages. We give the complete details of its adaptation to the UML. On the other hand, the method is fully automatic. The method has been implemented. We illustrate the method by means of its application to a case study that refines the Cyc ontology.

Alexander Schmitt,Wolfgang Minkerught that support reasoning on sets of constraints. We propose novel approaches for presentation of sets of functional dependencies based on specific graphs. These approaches may be used for the elicitation of the full knowledge on validity of functional dependencies in relational schemata.

A Reference Methodology for Conducting Ontological Analyses a procedural model for the ontological analysis based on the use of meta models, the involvement of more than one coder and metrics. This model is explained with examples from various ontological analyses.
