PROBLEM TO BE SOLVED: To obtain a text mining device and a method having such a general usability that can analyze even Web pages as analysis objects. SOLUTION: The text mining device is provided with a feature expression extraction rule storage part 1, a feature expression extraction part 2 for extracting a 1st description unit including intended extraction expression as a feature expression extraction result and outputting the extraction result together with the extraction intention, a related expression extraction rule storage part 3 for allowing a relation name of each 1st description unit to correspond to relation expression, and a related expression extraction part 4 for extracting a 2nd description unit from the feature expression extraction result as a related expression extraction result and outputting the extracted result together with the relation name. The device is provided also with a related expression integrated knowledge storage part 5 for integrating the feature expression and the related expression on the basis of relation of each 1st description unit, a related expression integration part 6 for outputting a related expression integration result and a classification part 7 for classifying the related expression integration result in accordance with the contents of the extraction intention.
