Provided are a related expression generation section that accepts an evaluation object expression, an linguistic expression to be evaluated, as input and generates a linguistic expression related to the evaluation object expression as a related expression; and a credibility calculation section that acquires the evaluation object expression and the related expression from a plurality of electronic documents along with time information and calculates credibility concerning the meaning of the evaluation object expression at a specific point in time by comparing the number of times that the acquired evaluation object expression appears and the number of times that the acquired related expression appears at the same time point.

Information analyzing device, information analyzing method, information analyzing program, and search system

A system includes a time-series data pattern checking means that receives time-series data from an input device and extracts a time-series pattern corresponding to the received time-series, and an effective period determination means that extracts an effective period corresponding to the time-series pattern from a time-series pattern/effective period correspondence table stored in a time-series pattern/effective period correspondence table storage means. The effective period determination means determines effective period time-series data which is a portion of the time-series data received from the input device in the effective period, according to the determined effective period and causes an output device to outputs the determined effective period and the determined effective period time-series data.
