Abstract: In an information processing apparatus, an extracting unit extracts a feature quantity from a subject content. A detecting unit detects from the second content a similar portion where a degree of coincidence between each feature quantity extracted from the second content and the feature quantity included in the key information is higher than a first threshold value, and outputs range information specifying a range of the similar portion. A correspondence generating unit retrieves the similar portion included in the range indicated by the detected range information, and generates correspondence information associating the retrieved similar portion with the key information. A presenting unit presents the key information selectably based on the correspondence information.

Abstract: An acquiring unit acquires a first search criterion from outside. A first searching unit extracts a first search result that satisfies the first search criterion from a storing unit that stores information to be searched. A first output unit outputs the first search result to a first output device. A changing unit changes the first search criterion to a second search criterion based on a predetermined condition. A second searching unit extracts a second search result that satisfies the second search criterion from the storing unit. A second output unit outputs the second search result to a second output device that is different from the first output device.
