Abstract

A method and system is provided that in a fully automated manner updates a database system containing product-related information in an automated comparative shopping system. An exemplary method according to the invention is a method that updates a database by extracting first product-related information about a product from a merchant web page, normalizing the first product-related information into first records, and storing the first records in a database system on a recording-medium on a server. Second product-related information about the product from the merchant web page is then extracted and transferred to the server. The second product-related information is normalized into second record. The second records are compared with the first records to determine which are most current, and the first records are updated to reflect the product-related information in the second records if the second records are more current than the first records.

Claims

1. A method for updating a database system containing product-related information in an automated comparative shopping system, the method comprising:

a. extracting first product-related information about a product from a merchant web page;

b. normalizing the first product-related information into first records;

c. storing the first records in a database system on a recording-medium on a server;

d. extracting second product-related information about the product from the merchant web page;

e. transferring the second product-related information to the server;

f. normalizing the second product-related information into second records;

g. comparing the second records with the first records to determine which are most current; and

h. updating the first records to reflect the product-related information in the second records if the second records are more current than the first records.

2. The method of claim 1, wherein the first product-related information is extracted by a web crawler stored on a recording-medium on a first computer.

3. The method of claim 1, wherein the second product-related information is extracted by a client application stored on a recording-medium on a second computer operated by a user of the comparative shopping system.

4. The method of claim 1, wherein the first and second product-related information includes the price of the product.

5. The method of claim 1, wherein the first and second product-related information includes available discounts on the product.

6. The method of claim 1, wherein the first and second product-related information includes the cost of shipping the product to a user of the comparative shopping system.

7. A system for updating a database system containing product-related information in an automated comparative shopping system comprising:

a first computer having a first computer-readable medium containing a database system, wherein the database system includes first records containing first product-related information about a product available for sale on a merchant web page and a first computer program configured to update the database system; and

a second computer coupled to the first computer having a second computer-readable medium containing a second computer program configured to identify and extract second product-related information about the product from the merchant web page and transfer second records containing the second product-related information to the first computer;

wherein the first computer program normalizes the second records into the same format as the first records, compares the first and second records to determine which are the most current, and updates the database system to reflect the most current product-related information.

8. The system of claim 7, wherein the first product-related information is extracted from the merchant web page by a web crawler stored on a recording-medium on a third computer.

9. The system of claim 7, wherein the second computer is a user computer operated by a user of the comparative shopping system.

10. The system of claim 7, wherein the first and second product-related data includes the price of the product.

11. The system of claim 7, wherein the first and second product-related information includes available discounts on the product.

12. The system of claim 7, wherein the first and second product-related information includes the cost of shipping the product to a user of the comparative shopping system.
