Disclosed herein is a display control processing apparatus including: display control means configured to display pieces of metadata for a predetermined group of music each serving as a favorite with a user on a metadata display portion for displaying the pieces of metadata in a format allowing the user to specify a desired piece of the metadata; specification means configured to specify a piece of the metadata displayed on the metadata display portion by the display control means; determination means configured to select a music with its metadata corresponding to metadata specified by the specification means from the pieces of metadata displayed by the display control means on the metadata display portion as metadata for the predetermined group of music and to determine the selected music as music to be recommended to the user; and reproduction means configured to reproduce music determined by the determination means.
摘要:
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.
