Abstract

A method and system is provided that in a fully automated manner generates and stores records regarding online product offerings from a variety of merchants, obtains records relating to a product displayed on a merchant web page, then normalizes and compares the two records to determine whether or not the products they represent are a match. An exemplary method according to the invention is a method for comparing and validating product data. First records that describe a plurality of first products are generated and stored in a database system. Second records that describe a second product are obtained from a web site, and normalized into the same format as the first records. The second records are then compared to the first records to determine whether or not they relate to the same product.

Claims

1. A method for comparing and validating product data, the method comprising:

a. generating first records that describe a plurality of first products;

b. storing the first records in a database system;

c. obtaining from a web page second records that describe a second product;

d. normalizing the second records into the same format as the first records; and

e. comparing the second records to the first records to determine whether or not the second product matches one of the first products.

2. The method of claim 1, wherein the first records are derived from a plurality of product titles.

3. The method of claim 1, wherein the first records are stored as canonical titles.

4. The method of claim 1, wherein the first and second records each comprise a set of feature fields that reflect features of the first and second product titles respectively.

5. The method of claim 4, wherein one of the features is the name of the product.

6. The method of claim 4, wherein one of the features is the color of the product.

7. The method of claim 4, wherein one of the features is an identification number related to the product.

8. The method of claim 4, wherein the contents of the feature fields of the second records are compared to the contents of the feature fields of the first records to determine how many match.

9. The method of claim 8, wherein each feature field is assigned a weight that reflects the importance of that field.

10. The method of claim 9, wherein the weight assigned to each feature field varies by type of product.

11. The method of claim 9, wherein the weights are expressed as a number.

12. The method of claim 11, wherein a numerical score is generated for each comparison.

13. The method of claim 12, wherein the numerical score reflects how closely the second product matches a first product.

14. A system comprising:

a first computer having a first computer-readable medium containing a plurality of first records that describe a plurality of first products; and

a second computer coupled to the first computer having a second computer-readable medium containing one or more second records that describe a second product;

wherein the second records are normalized into the same format as the first records and compared to the first records to determine whether or not the second product matches one of the first products.

15. The system of claim 14, wherein the first records are derived from a plurality of product titles.

16. The system of claim 14, wherein the first records are stored in a database system as canonical titles.

17. The system of claim 14, wherein the first and second records each comprise a set of feature fields that reflect features of the first and second product titles respectively.

18. The system of claim 17, wherein one of the features is the name of the product.

19. The system of claim 17, wherein the contents of the feature fields of the second records are compared to the contents of the feature fields of the first records to determine how many match.

20. The system of claim 18, wherein each feature field is assigned a weight that reflects the importance of that field.

21. A method for updating product data, the method comprising:

a. generating first records that describe a plurality of first products;

b. storing the first records in a database system;

c. obtaining from a web page second records that describe a second product;

d. normalizing the second records into the same format as the first records;

e. comparing the second records to the first records to determine whether or not the second product matches one of the first products; and

f. if the second product matches one of the first products, updating the first records to reflect the information contained in the second records.
