Ontologies as used in conceptual modelling and the semantic web are designed based on different, sometimes mutually incompatible, practices: as top-down theories, as emerging from linguistic evidence, as motivated by a set of tasks, as a result of an evolutionary social process, etc.
I will make an assessment of the dimensions that can be used to analyze/evaluate an ontology, and will present a set of pattern-based methods for ontology design, a typology of patterns, some examples, and a summary (time-permitting) of the eXtreme Design approach.
A separate hands-on session using eXtreme Design with the NeOn Toolkit will be held on a next date.
