A new approach to knowledge acquisition by repertory grids

Personal construct theory is one of the important tools for knowledge acquisition. It provides an expert’s opinion of the relationship between objects and their properties in the form of a repertory grid. The current techniques provide the repertory grid in the form of a matrix of integers. This paper describes the preliminary attempts for elicitation and analysis of repertory grid using a range of integers for each relationship. Such an elicitation leads to a more natural description of the expert’s knowledge in addition to a better user interface.
