Abstract

An information processing apparatus includes a content reproduction unit, a content part specification unit, a clustering unit, a class detection unit, a common class extraction unit, and a content retrieval unit. The content reproduction unit is configured to reproduce a reproduction content. The content part specification unit is configured to specify a plurality of content parts included in the reproduction content. The clustering unit is configured to classify the plurality of content parts into a plurality of clusters. The class detection unit is configured to detect a class from the plurality of content parts included in each of the plurality of clusters. The common class extraction unit is configured to extract a common class common to the plurality of clusters from the classes detected by the class detection unit. The content retrieval unit is configured to retrieve a content corresponding to the common class.

Claims

1. An information processing apparatus, comprising:

a content reproduction unit configured to reproduce a reproduction content;

a content part specification unit configured to specify a plurality of content parts included in the reproduction content;

a clustering unit configured to classify the plurality of content parts into a plurality of clusters;

a class detection unit configured to detect a class from the plurality of content parts included in each of the plurality of clusters;

a common class extraction unit configured to extract a common class common to the plurality of clusters from the classes detected by the class detection unit; and

a content retrieval unit configured to retrieve a content corresponding to the common class.

2. The information processing apparatus according to claim 1, wherein

the content part specification unit specifies the plurality of content parts in response to specification by a user.

3. The information processing apparatus according to claim 1, wherein

the content part specification unit specifies the plurality of content parts on the basis of a feature amount extracted from the reproduction content.

4. The information processing apparatus according to claim 1, wherein

the class detection unit performs an ontology process for the plurality of content parts included in each of the plurality of clusters to detect the class from the plurality of content parts.

5. The information processing apparatus according to claim 1, wherein

the clustering unit classifies the plurality of content parts into the plurality of clusters on the basis of feature amounts detected from the plurality of content parts.
