    Constructive induction is the creation of new terms for describing and learning concepts more effectively. An approach to the problem that uses inductive test incorporation, for fast and effective assessment of terms, is presented. The authors investigate specific effects of system components using two domains: a well-known medical problem, and the relatively unsolved problem of protein folding. T... View full abstract»

    Reasoning from previous experience, or case-based reasoning, has been used in numerous domains. The basic metaphor for case-based reasoning is one of analogical reasoning. The author presents a semantic representation structure based on NIKL to capture the analogic reasoning metaphor behind case-based reasoning. This provides numerous benefits, including conceptual organization and explanation sup... View full abstract»
