Method and system for providing access to information of potential interest to a user
First Claim
1. A method of providing access to information of potential interest to a user of an electronic device, comprising the steps of:
- while content is being displayed on the device, periodically updating a first word buffer with words extracted from closed captioning information corresponding to the content since a beginning of a program or story, and periodically updating a second word buffer with words extracted from closed captioning information corresponding to the content based on a most recent n seconds, wherein n is a preset value, such that the second word buffer maintains keywords only present in the closed captioning information during the last n seconds of time;
monitoring the user interaction with the device to identify when the user provides user input indicating an interest in learning more information about content currently being displayed on the electronic device;
wherein said device comprises a TV;
wherein said monitoring further includes monitoring user interaction with the TV;
extracting keywords from the second word buffer based on frequency of appearances of words in the first word buffer by analyzing the closed-caption information provided to the user via the TV currently stored in the first and the second word buffers;
converting the extracted keywords into a foreign language;
determining key information, includes supplementing the extracted keywords with keywords related to contextual information about the content of a channel being watched, based on the extracted keywords when the user input indicating the interest is identified; and
searching available sources for information of potential interest to the user based on said key information.

Abstract
The present invention provides a method and system for providing access to information of potential interest to a user. Closed-caption information is analyzed to find related information on the Internet. User interactions with a TV which receives programming including closed-caption information are monitored to determine user interests. The related closed-caption information is analyzed to determine key information therein. The key information is used for searching for information in available resources such as the Internet, and the search results are used to make recommendations to the user about information of potential interest to the user.

13. A system for providing access to information of potential interest to a user of a device, comprising:
-
a processor; a memory; an indexer that is configured to while content is being displayed on the device, periodically update a first word buffer in the memory with words extracted from closed captioning information corresponding to the content since a beginning of a program or story and periodically updating a second word buffer in the memory with words extracted from closed captioning information corresponding to the content based on a most recent n seconds, wherein n is a preset value such that the second word buffer maintains keywords only present in the closed captioning information during the last n seconds of time; a monitor that is configured to monitor user interaction with the device; wherein said device comprises a TV; wherein said monitor further configured to monitor user interaction with the TV; an analyzer that is configured to extract keywords from the second word buffer based on frequency of appearances of words in the first word buffer by analyzing the closed-caption information provided to the user via the TV currently stored in the first and the second word buffers and to determine key information, includes supplementing the extracted keywords with keywords related to contextual information about the content of a channel being watched, based on the extracted keywords when the user input indicating the interest is identified; a converter configured to converting the extracted keywords into a foreign language; and a searcher configured to search for information of potential interest to the user based on said key information. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
