Abstract: Disclosed is an information providing system comprising a receiving unit that receives an information request from a requester, a data storage unit that stores data, a detection processing unit that analyzes the content of the information request and extracts provision candidate data corresponding to the information request from the data storage unit, a responder output device to which the content of the information request and the provision candidate data are output, a responder input device that receives instruction information on whether or not the provision candidate data is to be provided, a response control unit that determines whether or not there is providable data based on the received instruction information and the provision candidate data, and an answer generating unit that generates answer data using the decision result by the response control unit.

Abstract: The need for a user to select by themselves a word or word string about which the user wants to obtain information from among words or word strings presented by a system can be eliminated. An information selecting system includes word string extracting unit for extracting words or word strings from input data, a statistical data obtaining unit for obtaining statistical data concerning the words or word strings extracted by the word string extracting unit from a group of electronic documents related to the user, and selecting unit for selecting a word or word string inferred to be less understood by the user on the basis of statistical data obtained by the statistical data obtaining unit.
