Configuration Using PLAKON - An Applications Perspective
PLAKON is a tool for building Planning and Configuration Expert Systems in technical domains. It is currently being developed and tested within the joint BMFT-project TEX-K. In this paper, an overview of the PLAKON software components is given. The basic mechanisms are explained and exemplified by a typical configuration application, the configuration of Automatic X-ray Inspection Systems. Emphasis is laid on the definition of a taxonomically- and compositionally-structured conceptual hierarchy with formulation of constraints and control knowledge.
To assist Java programming educations, we have developed a Web-based Java Programming Learning Assistant System (JPLAS). JPLAS provides fill-in-blank problems to study the Java grammar by filling blank elements in a high-quality code that are composed of reserved words, identifiers, and control symbols. A graph-based blank element selection algorithm has been proposed to automatically select as many blanks as possible that have grammatically correct unique answers. In this paper, we show and discuss their application results to a Java programming course in our department.
