Abstract

A content provider system interacts with a network of web sites to provide behavior-based content to users. Operators of the web sites add widgets to selected web pages of their sites. The widgets, when executed on the computing devices of users who view the selected web pages, report user-generated events to the content provider system. The content provider system analyses the reported events to detect behavioral associations between particular web sites, web pages, products, and/or other types of items. The widgets may also retrieve and display behavior-based content that is based on these item-to-item behavioral associations. For example, when a user views a particular web page, a widget on that page may request and display descriptions of, and links to, other sites or pages that are (a) behaviorally related to the page being viewed or an item represented thereon, and/or (b) behaviorally related to the past browsing activities of the particular user.

Claims

1. A computer-implemented method, comprising:

generating a mapping of particular web sites to particular catalog items represented in an electronic catalog of items, said mapping generated, at least in part, by detecting co-occurrences of particular web sites and particular catalog items in event histories of users, said mapping represented in computer storage;

maintaining a record of a plurality of web sites accessed by a user computing device, said record maintained, at least in part, by recording web site access events reported by the user computing device via execution of widget code included in web pages of said plurality of web sites; and

when the user computing device requests a web page of a web site that hosts the electronic catalog of items, using at least the record of the plurality of web sites accessed by the user computing device, in combination with said mapping of particular web sites to particular catalog items, to select a personalized set of catalog items to present on said web page.

2. The method of claim 1, wherein generating the mapping comprises:

maintaining, for each of a plurality of users, an event history that identifies web sites accessed by the respective user and catalog items selected by the respective user; and

collectively analyzing the event histories to identify particular web sites that are associated with particular catalog items.

3. The method of claim 1, further comprising incorporating descriptions of the personalized set of catalog items into the web page, and transmitting the web page from a web server to the user computing device.

4. The method of claim 1, wherein the user computing device is a device that has not previously selected any items from the electronic catalog.

5. The method of claim 1, wherein the user computing device has previously selected one or more catalog items from said electronic catalog, and the method further comprises taking said one or more catalog items into consideration in selecting said personalized set of catalog items to present on said web page.

6. The method of claim 1, wherein the method further comprises using information regarding particular web pages accessed by the user computing device across said plurality of web sites, in combination with a mapping of page-to-product associations, to select said personalized set of catalog items to present.

7. The method of claim 1, wherein the method further comprises using information regarding particular catalog items selected via the user computing device across said plurality of web sites, in combination with data regarding cross-site behavioral associations between catalog items, to select said personalized set of catalog items to present.

8. The method of claim 1, wherein the method is performed by a content provider system that hosts the electronic catalog, said content provider system being separate from said plurality of web sites.

9. A content provider system configured and programmed to perform the method of claim 1.

10. A system, comprising:

an event recording system that maintains, for each of a plurality of users, at least (1) a record of catalog items selected by the respective users from an electronic catalog of a first web site, and (2) a record of other web sites accessed by the respective user;

an association mining system that analyzes the records of catalog item selections and web site accesses of users on an aggregated basis to detect behavioral associations between particular web sites and particular catalog items; and

a recommendation system configured to use the detected behavioral associations, in combination with a record of web sites accessed by a target user, to generate personalized catalog-item recommendations for the target user.

11. The system of claim 10, wherein the event recording system detects at least some of said web site accesses by interacting with widget code included in web pages of said other web sites.

12. The system of claim 10, wherein each of said other web sites includes at least one web page that includes widget code that, when executed on a user computing device, causes the user computing device to report a web site access event to the event recording system, and the event recording system uses the web site access events reported via said widget code to maintain the records of other web sites accessed.

13. The system of claim 10, wherein the recommendation system is part of a content provider system that hosts the first web site, said content provider system configured to incorporate personalized recommendations generated by said recommendation system into web pages of the first web site.

14. The system of claim 10, wherein the recommendation system is capable of generating said personalized catalog-item recommendations for a target user that has not previously selected any catalog items.

15. The system of claim 10, wherein the recommendation system is additionally configured to take into consideration one or more catalog items selected by the target user in generating the personalized catalog-item recommendations for the target user.

16. The system of claim 10, wherein the recommendation system is additionally configured to used the detected behavioral associations, in combination with a record of catalog items selected by the target user, to generate personalize web site recommendations for the target user.
