Abstract
A system for determining content topicality comprises a feature value extracting means which extracts feature values of a plurality of contents from the contents; a content grouping means which compares the feature values of the plurality of contents extracted by the feature value extracting means, obtains identical contents and derived contents created using the contents, both of which are included in the plurality of contents, and groups the identical/derived contents, thereby computing identical/derived content grouping information; and a topicality determining means which totals viewing frequencies of the contents determined to be the identical/derived contents from viewing history information and the identical/derived content grouping information relating to the plurality of contents, computes total viewing frequencies of each of the identical/derived contents, and determines the topicality of the identical/derived contents according to the total viewing frequency.
