INFORMATION PROCESSING APPARATUS, AND DATA MANAGEMENT METHOD

摘要

An information processing apparatus (100) encodes text data by using a word dictionary (131) that allocates each of a plurality of words in a word group to a corresponding code and generates a count map (132) indicating an appearance frequency of the plurality of words in the word group in the text data. The information processing apparatus (100) associates the count map with encoded text data and stores it to a storage unit (130).
