Abstract:

In this paper, we describe case-based techniques in a medical application. We developed a prototype of an antibiotics therapy adviser within the ICONS project between 1993 and 1995. Now we are going to improve and extend this prototype, which we have already presented at the CBR workshop within XPS-95. At that time we focused mainly on the application. Here we stress on the case-based techniques. Some adaptations do not really belong to the Case-Based Reasoning paradigm though information from former cases is considered. We attempted to solve the problem of the continuously increasing number of stored cases in this incrementally working system by generalising from specific cases to prototypes. Here we present results of threshold settings for our prototype design. They show that the chosen design, which was based on experiences with diagnostic tasks, is not only advantageous for this therapeutic application, but that it contains a slight drawback as well. 1.
