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 will not be generated during such an abduction
procedure.
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 the application such as recommendation strategies
in shops, the different strategy can be conducted. That is,
items that users usually buy can be recommended. These strategies can be
selected according to the user's sitution.
Finally, I briefly illustrate the process of IMDJ strategy (proposal production)
by the extended abduction. In IMDJ, proposal production procedure can
be regarded as an abduction.
