Zusammenfassung
MEDICO aims to develop an intelligent, robust, and scalable
semantic search engine for medical images. The search engine of the
MEDICO demonstrator RadSem is based on formal ontologies and designated
for different kinds of users such as medical doctors or patients.
An explanation facility integrated into RadSem justifies search results
by showing a connection between query and result. The constructed explanations
are depicted as semantic networks containing various medical
concepts and labels. This paper addresses the tailoring of justifications
to different kinds of users regarding such quality aspects as understandability
or amount of information. A user experiment shows that under
certain conditions the quality of justifications can be pre-estimated by
considering the usage frequency of medical terms in natural language.
