Abstract: The present invention provides a system and method for building and analyzing a quantitative model from qualitative tacit knowledge. In one aspect of the present invention, there is provided a system for creating and analyzing a model of a user's semantic knowledge. The semantic knowledge model is based on cause and effect relationships as defined by the user. In another aspect of the present invention, there is provided a system for creating and analyzing a model of a user's episodic knowledge. The episodic knowledge model is based on the user's past experiences, including recalled stimuli and responses. The semantic and episodic models are used to describe the users internal mental model.
