Abstract

A method for finding similar search terms (word matching) is provided. The method receives a query of at least a first word and automatically applies the first word to a vocabulary amplifier. The vocabulary amplifier retrieves an associated word for the first word and accesses one or more database sources to retrieve an associated word. Each associated word is presented to an output interface. The amplifier then receives information from an input interface for the associated word and classifies the associated word based upon the received characterizing information.

Claims

1. A method for providing query expansion, comprising:

receiving a query comprising at least a first word;

automatically applying said first word to a vocabulary amplifier;

operating said vocabulary amplifier to execute the following steps;

automatically accessing one or more database sources to retrieve an associated word;

automatically presenting each said associated word to an output interface;

receiving characterizing information from an input interface for said associated word; and

automatically classifying said associated word based upon said received characterizing information.

2. The method in accordance with claim 1, comprising:

repeating the operation of said vocabulary amplifier with said first word for retrieving additional associated words.

3. The method in accordance with claim 2, comprising:

providing said vocabulary amplifier with an algorithm to determine when to terminate retrieving any further additional associated words.

4. The method in accordance with claim 3, comprising;

utilizing said algorthm to provide a dynamic stopping criteria for retrieving said additional associated words.

5. The method in accordance with claim 1, comprising:

providing a thesaruri as one of said database sources.

6. The method in accordance with claim 2, comprising:

providing said vocabulary amplifier with a learning algorithm such that said vocabulary amplifier utilizes each said associated word to learn the intended meaning of said first word.

7. The method in accordance with claim 6, wherein:

utlizing each said intended meaning to retrieve associated words having increased semantic proximity to said first word.

8. A method for providing query expansion, comprising:

receiving a query comprising at least a first phrase;

automatically applying said first phrase to a vocabulary amplifier; and

operating said vocabulary amplifier to execute the following steps;

automatically accessing one or more database sources to retrieve an associated word or phrase;

automatically presenting each said associated word or phrase to an output interface;

receiving characterizing information from an input interface for said associated word or phrase; and

automatically classifying said associated word or phrase based upon said received characterizing information.

9. The method in accordance with claim 8, comprising:

providing said vocabulary amplifier with a learning algorithm such that said vocabulary amplifier utilizes each said associated word or phrase to learn the intended meaning of said first phrase.

10. The method in accordance with claim 9, wherein:

utlizing each said intended meaning to retrieve associated words or phrases having increased semantic proximity to said first word or phrase.

11. The method in accordance with claim 10, comprising:

providing said vocabulary amplifier with a second algorithm to determine when to terminate retrieving any further additional associated words or phrases.

12. The method in accordance with claim 11, comprising;

utilizing said second algorthm to provide a dynamic stopping criteria for retrieving said additional associated words.

13. A method for providing query expansion, comprising:

providing a processor coupled to input/output apparatus comprising an input interface and an output interface;

providing a memory coupled to said processor and containing a learning machine program, a trained classifier program, and a memory portion for storing ranked list candidates;

providing said processor with access to one or more database sources;

providing said processor with a query comprising at least a first phrase;

automatically operating said processor with said learning machine program and said trained classifier program to access said one or more database sources to retrieve an associated word or phrase;

automatically operating said processor to present each said associated word or phrase to said output interface;

receiving characterizing information from said input interface by said processor for said associated word or phrase; and

operating said processor automatically to classify said associated word or phrase based upon said received characterizing information.

14. The method in accordance with claim 13, comprising:

providing said learning machine program with a learning algorithm to utilize each said associated word or phrase and its characterizing information to learn the intended meaning of said first phrase.

15. The method in accordance with claim 14, wherein:

said processor utlizes each said intended meaning to retrieve from said one or more database sources associated words or phrases having increased semantic proximity to said first word phrase.

16. The method in accordance with claim 15, comprising:

operating said processor with a second algorithm to determine when to terminate retrieving any further additional associated words or phrases.

17. The method in accordance with claim 16, comprising:

said processor utilizing each said associated word or phrase having first characterizing information in conjunction with said second algorithm.

18. The method in accordance with claim 17, comprising:

utilizing each said word or phrase having said first characterizing information to generate one or more additional queries.

19. The method in accordance with claim 18, comprising:

utilizing said query and said one or more additional queries to identify documents for retrieval.
