Abstract

An electronic apparatus includes a storage section, a first generation section, a second generation section, an update section, and an output section. The storage section stores contents, titles thereof, and viewing history information on viewing histories of the contents by a user. The first generation section generates, based on the stored viewing history information, recommendation display information containing as a recommended-content list a list of titles of contents that the user has not viewed among the stored contents. The second generation section generates dependence information on first and second contents among the stored contents by analyzing text information on a network, the second content being created dependently on the first content. The update section updates, based on the dependence information, the recommendation display information so that the user is prevented from viewing the second content before the first content. The output section outputs the updated recommendation display information.

Claims

1. An electronic apparatus, comprising:

a storage means for storing a plurality of contents, titles of the plurality of contents, and viewing history information on viewing histories of the plurality of contents by a user;

a first generation means for generating, based on the stored viewing history information, recommendation display information that contains as a recommended-content list a list of titles of contents that the user has not viewed out of the plurality of stored contents;

a second generation means for generating dependence information on a first content and a second content out of the plurality of stored contents by analyzing text information on a network, the second content being created by being dependent on the first content;

an update means for updating, based on the dependence information, the recommendation display information so that the user is prevented from viewing the second content before the first content; and

an output means for outputting the updated recommendation display information.

2. The electronic apparatus according to claim 1,

wherein the update means adds a title of the first content to the recommended-content list when the second content is contained in the recommended-content list but the first content is excluded therein.

3. The electronic apparatus according to claim 2,

wherein the update means updates the recommendation display information so that a title of the second content is displayed in subordination to the title of the first content.

4. The electronic apparatus according to claim 2,

wherein the update means updates the recommendation display information so that information notifying that, before the second content, the first content is to be viewed is output, when a title of the second content displayed on the recommended-content list is selected based on the recommendation display information by an operation of the user.

5. The electronic apparatus according to claim 1,

wherein the update means deletes a title of the second content from the recommended-content list when the title of the second content is contained in the recommended-content list but a title of the first content is excluded therein.

6. The electronic apparatus according to claim 1,

wherein the storage means stores creation year information indicating creation years of the plurality of contents and a predetermined keyword indicating dependence, and

wherein the second generation means includes

an extraction means for extracting a first title out of the plurality of titles from the text information,

a retrieval means for retrieving a second title different from the first title and the predetermined keyword from a predetermined range of a text in the text information, the predetermined range including the extracted first title, and

a judgment means for judging, when a predetermined number or more of the second titles are retrieved and the predetermined keyword is retrieved, that a content having an earlier creation year of the creation years is the first content and a content having later creation years of the creation years is the second content out of the two contents corresponding to the first title and the second title, based on the stored creation year information.

7. The electronic apparatus according to claim 1,

wherein the storage means stores creation year information indicating creation years of the plurality of contents, and

wherein the second generation means includes

a retrieval means for retrieving character names in the plurality of contents from the text information, and

a judgment means for judging, when the retrieved character names are common to two contents out of the plurality of contents, that a content having an earlier creation year of the creation years is the first content and a content having a later creation year of the creation years is the second content out of the two contents, based on the stored creation year information.

8. The electronic apparatus according to claim 7,

wherein the retrieval means further retrieves main character names in the plurality of contents, and

wherein the judgment means judges, when the retrieved character names are common to two contents out of the plurality of contents and the main character names in the two contents are different from each other, that a content having an earlier creation year of the creation years is the first content and a content having a later creation year of the creation years is the second content.

9. The electronic apparatus according to claim 1,

wherein the second generation means includes

a retrieval means for retrieving main character names in the plurality of contents from the text information, and

a judgment means for judging, when at least two of the main character names are retrieved from one content out of the plurality of contents and the at least two of the main character names are individually retrieved as main character names of other contents out of the plurality of contents, that the other contents are the first contents and the one content is the second content.

10. A content recommendation method, comprising:

storing a plurality of contents, titles of the plurality of contents, and viewing history information on viewing histories of the plurality of contents by a user;

generating, based on the stored viewing history information, recommendation display information that contains as a recommended-content list a list of titles of contents that the user has not viewed out of the plurality of stored contents;

generating dependence information on a first content and a second content out of the plurality of stored contents by analyzing text information on a network, the second content being created by being dependent on the first content;

updating, based on the dependence information, the recommendation display information so that the user is prevented from viewing the second content before the first content; and

outputting the updated recommendation display information.

11. A program causing an electronic apparatus to execute the steps of:

storing a plurality of contents, titles of the plurality of contents, and viewing history information on viewing histories of the plurality of contents by a user;

generating, based on the stored viewing history information, recommendation display information that contains as a recommended-content list a list of titles of contents that the user has not viewed out of the plurality of stored contents;

generating dependence information on a first content and a second content out of the plurality of stored contents by analyzing text information on a network, the second content being created by being dependent on the first content;

updating, based on the dependence information, the recommendation display information so that the user is prevented from viewing the second content before the first content; and

outputting the updated recommendation display information.

12. An electronic apparatus, comprising:

a storage section to store a plurality of contents, titles of the plurality of contents, and viewing history information on viewing histories of the plurality of contents by a user;

a first generation section to generate, based on the stored viewing history information, recommendation display information that contains as a recommended-content list a list of titles of contents that the user has not viewed out of the plurality of stored contents;

a second generation section to generate dependence information on a first content and a second content out of the plurality of stored contents by analyzing text information on a network, the second content being created by being dependent on the first content;

an update section to update, based on the dependence information, the recommendation display information so that the user is prevented from viewing the second content before the first content; and

an output section to output the updated recommendation display information.
