20090013053 | System and method for the dynamic generation of correlation scores between arbitrary objects - When an end user opens an e-mail the user's e-mail client requests the image content based on the image tag from a recommendation platform and sends an identification to the recommendation platform as part of the image URL. The user ID or seed item is looked up in the recommendation platform database and associated behavioral data and any applicable rules to generate content for the e-mail and the content is then displayed in the e-mail as an image. When the image is engaged, a request is sent to the recommendation platform that references the user or request identifier and a logical location in the image where the click occurred, the image location is looked up along with the user or request identifier to present the correct page or content for the user. | 01-08-2009 |
