摘要： In a rule generation apparatus, a rule generation unit generates a rule group for dividing a training example into a plurality of clusters related to target values using a rule base model so that a “first constraint” is satisfied. The training example includes at least one real example and at least one synthetic example. Each of the real and the synthetic examples includes a feature value vector of which vector elements are one or a plurality of feature values corresponding to feature parameters different from each other, and a target value. The feature value and the target value included in each of the real examples are measured values, while each of the synthetic examples is an example formed based on the real example. The “first constraint” includes a constraint that each of the clusters includes at least N (N is a natural number) real example.

摘要： The present invention does not simply extract all situations likely to become problems without any criteria; from among situations mentioned within text, the invention detects situations that a writer particularly considers to be a problem. From text for which detection is to be performed, descriptions representing events mentioned in the text are extracted in units of situations for each of the events. From among the extracted situations, a situation that the writer who has described the situation assumes to be a situation that actually occurs, and/or a situation that is not an ancillary explanatory description, is sorted out as a situation in which the writer has interest. From among the sorted out situations, a situation that includes at least one expression that may become a problem is output as a problem situation.

摘要： A policy creation apparatus capable of creating policies with high quality and high visibility is provided. A rule creation unit (302) creates a plurality of rule sets including a plurality of rules that are a combination of a condition for determining a necessity of an action to be taken regarding an object and the action to be performed when the condition holds. An order determination unit (304) determines an order of the rules in each of the plurality of rule sets. An action determination unit (306) determines whether or not the condition holds in accordance with the determined order, and determines the action when the condition holds.

摘要： An information processing apparatus 10 includes an acceptance unit 12, a formal language generation unit 14, an inference unit 16, and an update unit 18. The formal language generation unit 14 generates training expressions in a formal language based on parameters prepared in advance and pieces of text accepted by the acceptance unit 12. The inference unit 16 executes at least one inference out of deductive inference and abduction on the above training expressions using a knowledge base prepared in advance. The update unit 18 compares an inference result of the inference unit 16 with a model answer input in advance, and updates parameters such that an inference result that matches the model answer is likely to be obtained through inference performed by the inference unit 16.
