You see things,
and you say, "Why?"
I dream things that never were,
and I say, "Why not?"

Accurately locating concepts in ontologies has become an critical task today. Not only the Semantic Web, but also older classification systems, e.g. in the medical domain, rely on correctly chosen concepts for document retrieval as well as for statistical or billing purposes. At the Information Management Institute of the University of Neuchâtel I'm working with three methods through which concept retrieval from an medical ontology can be improved:
Based on the ICD10 I implemented a concept retrieval system to compare the performance of different combinations of these techniques. Within this context I conceptualised and implemented different techniques of stemming and word decomposition for the French medical language. The system found a wide and enthusiastic user base, so that the final evaluation can be carried out with over one million individual query processes from real users of the system.
Two prototype systems are currently available:
