Abstract

A category recommendation method includes maintaining a category database including an internal identifier and an internal category to which the internal identifier belongs; externally receiving a foreign identifier and a foreign category where the foreign identifier belongs to from an outside; extracting a query associated with the foreign identifier; and recommending at least one of the internal categories stored in the category database by using the query as a category corresponding to the foreign identifier.

Claims

1. A method of updating a product database, comprising:

providing a database comprising a plurality of database entries, wherein each database entry comprises a classification field and a plurality of additional fields, wherein the classification field comprises a classification of an item of the database entry;

providing data associated with a product item for adding to the database as a new entry;

generating a query from the data associated with the product;

computing a correlation value of the query with information saved in at least one selected field of a database entry, wherein computing is repeated for at least part of the plurality of database entries;

identifying database entries including information in the at least one selected field, which has a correlation value greater than a predetermined value;

determining the most popular classification among classifications saved in the classification fields of the identified database entries; and

assigning the most popular classification to the classification field of the new entry.

2. The method of claim 1, wherein the data is retrieved from an on-line store for selling the product.

3. The method of claim 2, wherein the query comprises a word or phrase that the on-line store uses to identify, describe or classify the product.

4. The method of claim 2, wherein the plurality of fields further comprises a product source field, wherein the method further comprises adding to the product source field a name of the on-line store.

5. The method of claim 2, wherein the plurality of fields further comprises a price field, wherein the method further comprises adding to the price field a price of the product available at the on-line store.

6. The method of claim 5, further comprising filtering the price field of a group of database entries using a price range so as to select a smaller group of entries with a price falling in the price range.

7. The method of claim 1, providing data comprises receiving the data from an on-line store, wherein the data comprises at least one selected from the group consisting of a name of the product, a classification of the product, an identification code of the product, and a description of the product that are used in the on-line store.

8. The method of claim 7, wherein the query is created using terms in the name of the product, the classification of the product, the identification code of the product, and the description of the product.

9. The method of claim 7, wherein the plurality of fields comprise a product identification code field, wherein the method further comprises determining whether the database comprises a database entry having an internal identifier in the product identification code field that is identical to the identification code of the product that is used in the on-line store.

10. The method of claim 9, wherein generating, computing, identifying and determining are conducted only when it is determined that there is no database entry that includes the identical identification code in the product identification code field.

11. The method of claim 9, wherein the at least one selected field comprises the product identification code field.

12. The method of claim 9, wherein the at least one selected field comprises a field other than the product identification code field.

13. The method of claim 9, wherein the internal identifier is a model number of the product.

14. The method of claim 1, wherein the query comprises a string of plurality of words associated with the product.

15. The method of claim 1, wherein determining comprise:

identifying different classifications used in the identified database entries;

counting the number of database entries for each different classification; and

comparing the counted numbers to determine the most popular classification.

16. A method of running a price comparison engine, the method comprising:

maintaining a product database comprising the method of claim 1;

receiving, from a remote computer, a search request for a type of products;

conducting a search in the database using information included in the search request; and

sending a search result to the remote computer.

17. A method of a product database, comprising:

providing a product database comprising a plurality of fields for each database entry, the plurality of fields comprising a classification field;

providing data associated with a product for adding to the database as a new entry;

extracting at least one term from the data associated with the product;

conducting at least one search using the at least one term in the database so as to locate a plurality of entries including the at least one term in at least one field thereof; and

assigning, to the classification field of the new entry, information or a value that is the most popular in the classification fields of the plurality of entries located in the at least one search.

18. The method of claim 17, wherein the data is retrieved from an on-line store for selling the product.

19. The method of claim 18, wherein the data comprises at least one selected from the group consisting of a name of the product, a classification of the product, an identification code of the product, and a description of the product that are used in the on-line store.

20. The method of claim 19, wherein the query is created using terms in the name of the product, the classification of the product, the identification code of the product, and the description of the product.
