A Representation Scheme Using Both Frames and Rules

CENTAUR was designed in response to problems that occurred while using a purely rule-based system. The CENTAUR system offers an appropriate environment in which to experiment with knowledge representation issues such as determining what knowledge is most easily represented in rules and what is most easily represented in frames. In summary, much research remains to be done on this and associated knowledge representation issues. This present research is one attempt to make explicit the art of choosing the knowledge representation in AI by drawing comparisons between various approaches and by identifying the reasons for selecting one fundamental approach over another.
