ABSTRACT:
The present invention provides an information processing apparatus to administer a set of evaluation units for providing evaluation including classification, providing comments and so on to information based on the history of evaluation in the past. A data object or information specifying the data object is stored as an information unit in an information unit administering element to be administered, and a set of evaluation units (item such as classification, providing comments and so on) is stored in an evaluation unit set administering element and administered. Every time evaluation is provided to the information unit, information about the relation of association among the information unit, evaluation unit and the set of evaluation units is stored in an evaluation history administering element as a result of evaluation to be administered. Accordingly, a user is able to know by which set of evaluation units the evaluation is provided to a certain piece of information in detail by referring to the result of evaluation administered in the evaluation history administering element.
