Four phases including (A) tabulation from the object file group (F), (B) sorting in descending order of appearance frequency, (C) extraction up to the rank of a target appearance rate, and (D) map generation are executed. (A1) An information generating apparatus reads the object file group (F) and counts the appearance frequencies of basic words. (B1) After tabulation of the basic words in the object file group (F), the information generating apparatus sorts a basic word appearance frequency table (101) in descending order of appearance frequency, whereby the table is sorted in order from the highest appearance frequency and basic words are ranked in order from the highest appearance frequency. (C1) The information generating apparatus refers to the basic word appearance frequency table (101) after the sorting at (B1) and extracts the basic words ranked within a target appearance rate Pw. (D1) The information generating apparatus generates a specific basic word appearance map (M1) for a specific basic word group. |
