Abstract

Natural-language words are associated with content. The natural-language words are identified from, for example, metadata and/or the actual content itself. Each word identified for the content is associated with the identified genre of the content (from, for example, its tagged metadata). A database is then maintained having a number of occurrences of each word from the multiple content items for each genre. Once the word/genre database is created, subgenres for a particular program/content can be created by once again using statistics from the words identified for that program to rank the most appropriate genres for the words and produce sets of the highest ranked genres.

Claims

1. A method for classifying content, the method comprising the steps of:

identifying a particular program in order to determine a genre or category for the program;

creating a list of words associated with the program;

accessing a database comprising stored words and their associated genres or categories for each word; and

determining the genre or category for the program based on a comparison of the list of words with the stored words and their associated genres or categories.

2. The method of claim 1 wherein the database comprises stored words from multiple programs and their associated genres.

3. The method of claim 1 wherein the step of creating the list of words associated with the program comprises the step of identifying the words from metadata associated with the program.

4. The method of claim 1 wherein the step of creating the list of words associated with the program comprises the step of identifying the words directly from the content of the program.

5. The method of claim 1 further comprising the steps of:

determining a gross genre of the program from metadata; and

appending the list of words associated with the program and the gross genre to the database.

6. The method of claim 1 wherein the particular program comprises a television show, a video, internet content, an electronic document, or any content for which there exists metadata or a natural language representation of the content.

7. The method of claim 1 wherein the step of determining the genre or category for the program comprises the steps of:

determining words from the list of words that are most representative of the program;

determining the genre from the words that are most representative of the program.

8. The method of claim 1 wherein the step of determining the genre comprises the step of combining genre names together to form a single genre.

9. The method of claim 1 wherein the step of determining the genre or category for the program is additionally based on data obtained from a source outside the database.

10. A method for classifying content, the method comprising the steps of:

creating a database by;

creating a list of words associated with a first program;

determining a genre of the first program;

appending the list of words and their genre to a database;

determining a genre or category for a second program by;

identifying the second program in order to determine a genre or category for the program;

creating a second list of words associated with the second program

determining the genre of the second program by accessing the database and determining genres associated with words from the second list of words.

11. The method of claim 10 wherein the database comprises stored words from multiple programs and their associated genres.

12. The method of claim 10 wherein the step of creating the list of words associated with the programs comprises the step of identifying the words from metadata associated with the programs.

13. The method of claim 10 wherein the step of creating the list of words associated with the programs comprises the step of identifying the words directly from the content of the programs.

14. The method of claim 10 wherein the programs comprise a television show, a video, internet content, an electronic document, or any content for which there exists metadata or a natural language representation of the content.

15. The method of claim 10 wherein the step of determining the genre comprises the steps of:

determining words from the second list of words that are most representative of the program;

determining the genre from the words that are most representative of the program.

16. The method of claim 15 wherein the step of determining the genre comprises the step of combining genre names together to form a single genre.

17. The method of claim 10 further comprising the step of:

outputting the genre of the second program.

18. An apparatus comprising:

a database comprising stored words and their associated genres or categories for each word;

logic circuitry identifying a particular program in order to determine a genre or category for the program, creating a list of words associated with the program, accessing the database, and determining the genre or category for the program based on a comparison of the list of words with the stored words and their associated genres or categories.

19. The apparatus of claim 18 wherein the database comprises stored words from multiple programs and their associated genres.

20. The apparatus of claim 18 wherein the list of words associated with the program is created by identifying the words from metadata associated with the program.
