Abstract
We propose a method to maintain personal preference information for each concept and instance. We express such concepts and instances by XML format. The concepts are classified into three types; object concept, attribute concept, and action concept. The concept data manage the relationship with the other concepts and the aroused emotions from the events which imply the target concept. Then, favorite value (FV) of the concept is calculated from the relating concepts and the reminded emotions. Our method is applied into a fairy tale "little red cap" and calculate the FVs of the concepts and instances based on 48 concept/attribute data.
