Abstract
A learning system includes: an acquisition unit that obtains document data; a generation unit that generates a key phrase from the document data; a restoration unit that restores the document data from the generated key phrase; and a learning unit that learns parameters of the generation unit on the basis of the document data and the restored document data. According to such a learning system, high-precision learning can be performed even when there is no key phrase as a correct answer.
