Information processing apparatus, program, and information processing method

A non-transitory computer-readable storage medium having stored thereon, a set of instructions that, when executed by a computer, causes the computer to perform the steps comprising:

• reproducing a reproduction content;
• specifying a plurality of content parts included in the reproduction content;
• classifying the plurality of content parts into a plurality of clusters based on at least one object recognized in each of the plurality of content parts;
• detecting a plurality of classes, for each of the plurality of clusters, by performing an ontology process for the at least one object recognized in each of the plurality of content parts included in each of the plurality of clusters;
• extracting a plurality of common classes, common to the plurality of clusters, from the detected plurality of classes;
• retrieving the plurality of common classes as a plurality of retrieval keywords;
• retrieving a plurality of content corresponding to the plurality of common classes by searching using the plurality of common classes as retrieval keywords;
• and
• displaying the retrieved plurality of content and the extracted plurality of common classes as the plurality of retrieval keywords, wherein
• the at least one object recognized in each of the plurality of content parts that is used to classify the plurality of content parts into the clusters is a common subject found in each of the content parts, and
• the common subject used to classify the plurality of content parts into each cluster is used to detect the plurality of the classes for the respective cluster.

An information processing method, comprising:

• in an information processing apparatus:
• reproducing a reproduction content;
• specifying a plurality of content parts included in the reproduction content;
• classifying the plurality of content parts into a plurality of clusters based on at least one object recognized in each of the plurality of content parts;
• detecting a plurality of classes, for each of the plurality of clusters, by performing an ontology process for the at least one object recognized in each of the plurality of content parts included in each of the plurality of clusters;
• extracting a plurality of common classes, common to the plurality of clusters, from the detected plurality of classes;
• retrieving the plurality of common classes as a plurality of retrieval keywords;
• retrieving a plurality of content corresponding to the plurality of common classes by searching using the plurality of common classes as retrieval keywords;
• and
• displaying the retrieved plurality of content and the extracted plurality of common classes as the plurality of retrieval keywords, wherein
• the at least one object recognized in each of the plurality of content parts that is used to classify the plurality of content parts into the clusters is a common subject found in each of the content parts, and
• the common subject used to classify the plurality of content parts into each cluster is used to detect the plurality of the classes for the respective cluster.
