Abstract: A computer system for generating a user data store and analyzing the user data store comprises a memory and a processing circuit. The memory is configured to store a user data store comprising a plurality of graphs, each graph having a user identity node. The processing circuit is configured to, for each of the plurality of graphs: receive asset data representing an asset that a user has interacted with on a website; generate a first node representing the asset data and a first link coupling the first node to the user identity node of the graph; store the first node and first link as part of the graph; receive usage data representing user interaction with a website; generate a second node representing the usage data and a second link coupling the second node to the user identity node of the graph, wherein at least one of the first node and second node further represents opinion data for a product or evaluation data for a product; and store the second node and second link as part of the graph.

Abstract: A computer system for targeting offers to users of a web site comprises a memory and a processing circuit. The memory is configured to store a plurality of user attributes for a user and a plurality of rules defining when an offer is to be presented to a user. The processing circuit is configured to transmit a web page to a client device, to receive user interaction data from the client device representing interaction with the web page, to update the user attributes stored in memory in response to the received user interaction data, to determine whether the updated user attributes satisfy a rule, and based on whether the updated user attributes meet the rule to transmit an offer to the client device for display on the web page or a next web page.
