PROBLEM TO BE SOLVED: To provide a method for dynamically creating a snippet depending on a given text.SOLUTION: In a snippet generation device 11, a query analysis section 14 executes a morpheme analysis on a given text to break down the text into morphemes, and converts a pattern considering word conjugation of each morpheme into a normal expression; a key text selection section 16 searches the pattern on the object text, measures the frequency of the normal expression used, calculates a score of texts constituting the document based on the frequency of the normal expression used in the document and the frequency of the document used, and selects upper n texts in order from the higher score; and a text compaction section 17 deletes an unnecessary portion from the n texts into specified number of characters to generate a snippet.
