Patent ID: 7778988

Claim:
An information processing device comprising: generating means for generating, by a processor and on a basis of a plurality of contents, extracted information extracted from content information of said plurality of contents, and values indicated by said extracted information for each of said contents, a numerical model of said contents and a numerical model of said extracted information in a same space of two dimensions or more; calculating means for calculating, by the processor, degrees of association of sets of link destination candidate contents other than a predetermined link source content among said plurality of contents and said extracted information with said link source content, using the numerical model of said contents and the numerical model of said extracted information in said same space, the degrees of association indicating degrees to which the predetermined link source content and the extracted information are associated with each other as viewed from the link destination candidate contents; link detecting means for detecting, by the processor, a link destination content associated with said link source content and relativity information indicating relativity between said link destination content and said link source content on a basis of said degrees of association calculated by said calculating means; cluster generating means for generating clusters of said extracted information by grouping said extracted information, wherein: said calculating means converts the calculated degrees of association of the sets of said link destination candidate contents and said extracted information with said link source content into degrees of association corresponding to the clusters of said extracted information, and said link detecting means sets said link destination candidate content of said set having the degree of association higher than a threshold value, the degree of association corresponding to a cluster of said extracted information, as said link destination content, and sets representative extracted information representative of the cluster of said extracted information of said set as said relativity information; and presenting means for presenting said link destination content and said relativity information detected by said link detecting means.
