Abstract
An information processing apparatus performs topic analysis on one or more collected documents to calculate a probability indicating the degree of fitness of each sentence constituting the collected document for each item of a local topic, performs linguistic analysis on the collected document to detect a unique expression pattern in each item of the local topic, sets topic usefulness for each sentence constituting the collected document on the basis of evaluation of the sentence by an evaluator, sets a total evaluation value with respect to each item of the local topic on the basis of the topic analysis result and the topic usefulness, selects an item of the local topic on the basis of the total evaluation values, and extracts an appropriate sentence for a unique expression pattern in the selected item of the local topic from the collected document as a profound text candidate.
