Remedying the Reusability { Usability Tradeoo for Problem-solving Methods

We expect reuse of parts of knowledge-based systems to become more and more important in the near future, as opposed to building systems from scratch every time. It is, however, well known that there exists a tradeoo between usability and reusability: the more components become reusable, the less usable they become. This is due to the fact that, in order to have a working system, a gap has to be bridged between the general reusable part and the speciic application, and the higher the reusability, the larger this gap. In this paper, we enhance the reusability of problem-solving methods by describing them in a task-neutral way. We ll the resulting gap by semi-automatically mapping the task-neutral method to a particular domain.
