Paper Abstract

This paper presents a conceptual model of object-based knowledge representation for the inspection and evaluation of structural integrity. Use of the model is illustrated with a practical knowledge-based system(KBS) developed in the domain of bridge fatigue evaluation. An overview of the open-system architecture of the model is first introduced, followed by discussion of the object abstraction in the domain knowledge. Three major kinds of entities represented by objects are categorized in the model. They are : the physical objects for structural topology/interconnectivity as well as individual physical components, the equation objects for quantitative analysis, and abstract objects for qualitative assessment and reasoning. The knowledge representation scheme adapted by this KBS renders the notions of self-inferencing and self-indexing of knowledge in objects. Basic inferencing mechanisms of this model are also described in the paper. Finally, a critique of the hybrid representation is presented along with suggestions for its enhancement.
