Abstract:
1. An information processing apparatus implemented by a central processor (CPU) that constructs an information analysis processing configuration to be applied to information analysis processing in a target area including uncertainty, the apparatus comprising: a data processing section that performs processing of automatically creating a Partially Observable Markov Decision Process (POMDP) model from the input of attribute data including attribute information and an attribute value; and a rule storage section storing a rule to be applied to processing of creating a Partially Observable Markov Decision Process (POMDP) in the data processing section, the rule storage section storing at least one rule of rules defined in a Partially Observable Markov Decision Process (POMDP) including: (1) a rule relating to a state transition function; (2) a rule relating to an observation function; and (3) a rule relating to a reward function; and wherein the data processing section is configured to apply at least one of the rules relating to a state transition function, an observation function and a reward function; wherein the rule relating to an observation function is a rule defining a probability value to be given to each objection based on observation information obtained as an answer corresponding to the question, that is, a rule defining each of: a right answer observation probability value {OFr %}; a wrong answer observation probability value {OFw %}; and an irrelevant answer observation probability value {OFir %}; wherein the data processing section is configured to create a Partially Observable Markov Decision Process (POMDP) model by: performing, as an action, processing of creating and outputting a question based on the attribute data; obtaining the answer to the question as observation information; and performing processing of creating probability distribution information corresponding to an object based on the obtained observation information.
