1. An information-processing apparatus for constructing an information analysis processing configuration to foe applied to information analysis processing in an observation domain including an uncertainty, said information-processing apparatus comprising a data processing unit for; taking a Partially Observable Markov Decision Process as a basic configuration; taking each of elements included in every information space defined in said Partially Observable Markov Decision Process as a unit; analyzing relations between said elements; and constructing an Factored Partially Observable Markov Decision Process, which is a Partially Observable Markov Decision Process including said relations between said elements, on the basis of results of said analysis.
