SOLUTION DATA EDIT PROCESSING APPARATUS AND METHOD, AND AUTOMATIC SUMMARIZATION PROCESSING APPARATUS AND METHOD

The present invention achieves edit processing which enables a user to freely edit solution data that becomes supervised data when processing automatic summarization using machine learning, and achieves summarization processing specialized for the user using the solution data. A user's evaluation of the summary produced by automatic processing of a text is created, and case data using the text and the summary as a problem and the input evaluation as a solution is stored. A solution and feature-set pair is extracted from the stored cases, and learning result of what solution is apt to be produced at what feature is stored. Thereafter a summary-candidate is generated from the processing target text, a feature-set is extracted from the text and summary-candidate, a summary-candidate and estimated-solution pair is generated by estimating a feature-set referring to the stored learning result, and the summary-candidate pair is used as a summary.
