Knowledge Engineering Environment. Frame-based expert system.
Supports dynamic inheritance, {multiple inheritance},
polymorphism. Classes, meta-classes and objects are all
treated alike. A class is an instance of a meta-class. Can
control rules for merging of each field when multiple
inheritance takes place. Methods are written in LISP.
Actions may be triggered when fields are accessed or modified.
Extensive GUI integrates with objects. Can easily make object
updates to be reflected on display or display selections to
update fields. This can in turn trigger other methods or
inference rules which may then update other parts of the
display. Intellicorp, for TI Explorer. "The Role of
