Improving implementation of graphical user interfaces for object-oriented knowledge-bases
Olof C Johansson · 1991
Second generation knowledge-based systems have raised the focus of research from rulebased to model-based systems. Model-based systems allow knowledge to be separated into target domain model knowledge and problem solving knowledge. This work supports and builds on the hypothesis that fully object-oriented knowledge-bases provide the best properties for managing large amounts of target domain model knowledge. The ease by which object-oriented representations can be mapped to efficient graphical user interfaces is also beneficial for building interactive graphical knowledge acquisition and maintenance tools. These allow experts to incrementally enter and maintain larger quantities of knowledge in knowledge-bases without support from a knowledge engineer. The thesis points to recent advances in the conception of knowledge-based systems. It shows the need for efficient user interfaces for management of large amounts of heterogeneous knowledge components. It describes a user interface soft...
