Abstract

The present invention provides an information processing device including a generating section, a calculating section, a link detecting section, and a presenting section.

Claims

1. An information processing device comprising:

generating means for generating, 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 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;

link detecting means for detecting 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; and

presenting means for presenting said link destination content and said relativity information detected by said link detecting means.

2. The information processing device as claimed in claim 1,

wherein said link detecting means sets said link destination candidate content of said set having said degree of association higher than a threshold value as said link destination content, and sets the extracted information of said set as said relativity information.

3. The information processing device as claimed in claim 1,

wherein said presenting means displays said link destination content and said relativity information detected by said link detecting means.

4. The information processing device as claimed in claim 3,

wherein said presenting means displays all or a part of content information of said link destination content in correspondence with display of said link destination content.

5. The information processing device as claimed in claim 4,

wherein said presenting means highlights a part corresponding to said relativity information in said content information displayed in correspondence with the display of said link destination content.

6. The information processing device as claimed in claim 3,

wherein said presenting means determines a form of display of one of the link destination content and the relativity information on the basis of said degrees of association.

7. The information processing device as claimed in claim 1, further comprising 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.

8. The information processing device as claimed in claim 1, further comprising cluster generating means for generating link destination candidate clusters of said link destination candidate contents by grouping said link destination candidate contents,

wherein said calculating means calculates degrees of association of sets of said link destination candidate clusters and said extracted information with said link source content, and

said link detecting means sets a link destination candidate content belonging to said link destination candidate cluster of said set having said degree of association higher than a threshold value as said link destination content, and sets said extracted information of said set as said relativity information.

9. The information processing device as claimed in claim 1, further comprising inputting means for inputting content information,

wherein said generating means reconstructs the model of said contents by generating a vector corresponding to said extracted information of said content information input by said inputting means and adding the vector to the already generated numerical model of said contents.

10. An information processing method comprising the steps of:

generating, 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 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;

detecting 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 in a process of said calculating step; and

presenting said link destination content and said relativity information detected in a process of said link detecting step.

11. A program for making a computer perform a presenting process for presenting information indicating a content associated with a particular content, said presenting process comprising the steps of:

generating, 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 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;

detecting 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 in a process of said calculating step; and

presenting said link destination content and said relativity information detected in a process of said link detecting step.

12. An information processing device comprising:

a generating section for generating, 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;

a calculating section for calculating 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;

a link detecting section for detecting 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 section; and

a presenting section for presenting said link destination content and said relativity information detected by said link detecting section.
