INFORMATION PROCESSING APPARATUS, AND DATA MANAGEMENT METHOD

摘要

An information processing apparatus (100): encodes text data by using a word dictionary assigning each of a plurality of words in a word group to a corresponding code; and generates a coefficient map (132) displaying an appearance frequency that the plurality of words in the word group appear in the text data. The information processing apparatus (100) correlates the coefficient map with the encoded text data and stores the same in a storage unit (130).
