Abstract

An information processor is disclosed. The processor includes: a keyword extraction portion for extracting keywords from a text created by a user; a keyword information acquisition portion for acquiring given keyword information about the keywords extracted by the keyword extraction portion; an interest degree calculation portion for finding information about degrees of interest indicating user'"'"'s degrees of interest in the keywords, based on the keyword information; a keyword selection portion for selecting given keywords from the keywords extracted by the keyword extraction portion, based on the information about the degrees of interest; and a content decision portion for determining a content recommended to the user, based on the keywords selected by the keyword selection portion.

Claims

1. An information processor comprising:

a keyword extraction portion for extracting keywords from a text created by a user;

a keyword information acquisition portion for acquiring given keyword information about the keywords extracted by the keyword extraction portion;

an interest degree calculation portion for finding information about degrees of interest indicating user'"'"'s degrees of interest in the keywords, based on the keyword information;

a keyword selection portion for selecting given keywords from the keywords extracted by the keyword extraction portion, based on the information about the degrees of interest; and

a content decision portion for determining a content recommended to the user, based on the keywords selected by the keyword selection portion.

2. An information processor as set forth in claim 1, wherein the keyword information includes

information indicating an instant of time corresponding to an instant of time at which the text from which the keywords are extracted was created,

information indicating positions of the keywords in the text, and

information indicating the number of appearances of the keywords in the text.

3. An information processor as set forth in claim 1, wherein the text is associated with a recommended content, and wherein the keyword information is information indicating the kind of the content to which the text is related.

4. An information processor as set forth in claim 3, wherein the recommended content is a broadcast content, a network content, or a personal content.

5. An information processor as set forth in claim 1,

wherein the text is made up of plural items,

wherein there is further provided a text acquisition portion for acquiring a text of given items of the items constituting the text,

wherein the keyword extraction portion extracts keywords from the text of the items acquired by the text acquisition portion, and

wherein the keyword information acquisition portion acquires information indicating the kind of the items having the keywords extracted by the keyword extraction portion as the keyword information.

6. A method of information processing, comprising the steps of:

extracting keywords from a text created by a user;

acquiring given keyword information about the keywords extracted by processing of the extracting step;

finding interest degree information indicating degrees of interest of the user in the keywords, based on the keyword information;

selecting given keywords from the keywords extracted by processing of the extracting step, based on the interest degree information; and

determining a content recommended to the user, based on the keywords selected by processing of the selecting step.

7. A program for causing a computer to perform information processing including the steps of:

extracting keywords from a text created by a user;

acquiring given keyword information about the keywords extracted by processing of the extracting step;

finding interest degree information indicating degrees of interest of the user in the keywords, based on the keyword information;

selecting given keywords from the keywords extracted by processing of the extracting step, based on the interest degree information; and

determining a content recommended to the user, based on the keywords selected by processing of the selecting step.
