Abstract :
In this paper, we introduce the concept of “value” to the abduction procedure. In fact, “values” are dealt with outside of the abduction procedure. For usual abduction, we always consider values included in the knowledge (hard coded). However, for a certain procedure, such values are unnecessary and sometimes harmful. Outside of the main abduction procedure, the inference system can flexibly deal with “values” to generate hypotheses considering the user´s preference, situation, and the current trends, etc. In addition, we introduce the concept of the expiration of the hypothesis in the hypothesis generation. Recently generated hypotheses are not generated during such abduction procedure, in addition. Accordingly, the system can generate rather novel hypotheses to enjoy potential chances. This type of inference can be applied to daily life situations. Of course, according to application such as recommendation strategies in shops. the opposite strategy can be conducted.
