ABSTRACT:

The aim of our work is the definition of a knowledge engineering process, which supports an eLearning scenario in medical education. A significant benefit of eLearning is the possibility of an easier way to search and navigate learning objects. If a learner wants to learn something from an unknown knowledge domain, s/he needs special search facilities. For example the keywords from this knowledge domain can be organised in a transparent way: for instance, the typical causes of diseases or the typical effects of medications can be captured in a very systematic way as a conceptualisation of a knowledge domain, which is interconnected by semantic relations.

Well-defined types of such conceptualisations are ontologies. Such an exemplary conceptualisation was created during the k-med project. Typically the creation of such an ontology is an expensive task. That’s why we defined an algorithmic approach to extend such ontologies step by step. The approach is called ontology enrichment and focuses on the retrieval of new concepts for a given ontology. The basis for proposing new concepts to existing ones is always an examination of the natural language regularities in a domain specific text corpus. Our aim is to define an integration of standard multimedia courses and the ontology enrichment process.

BENEFIT TO PARTICIPANTS ATTENDING SESSION:

We present a systematic approach to cope with the expensive task of creating a knowledge representation for a specific medical domain. The demonstration shows benefits of knowledge enhanced multimedia medical education. Special graphic elements clarify the medical knowledge representation for non-experts.
