SEARCH WORD SUGGESTION DEVICE, METHOD FOR GENERATING UNIQUE EXPRESSION INFORMATON, AND PROGRAM FOR GENERATING UNIQUE EXPRESSION INFORMATION

A search word suggester extracts the column on left-hand end of table data, extracts a word arranged uppermost from words in the extracted column as the abstract word, and extracts words below the uppermost word in the extracted column as named entities for the abstract word. Then, the search word suggester generates abstract-word/named-entity data in which the extracted abstract word and the named entities for the extracted abstract word are associated with each other. Then, when the abstract word is input as a search word, the search word suggester refers to this abstract-word/named-entity data, and suggests a word as a result of combining the input search word with the named entity as a candidate of the search word to be used.
