Abstract: A methodology and automated system are provided whereby a merchant presents timely and relevant information to customers. The system includes a client-side local assistant system and a server-side component. The client-side local assistant system, which is download installed on a customer's computer, implements an automated client-side system that is fully data driven. The data is partly downloaded data, called rulesets, and partly data that is collected and stored locally, called interaction data. The client-side system includes functionality for specifying and interpreting rulesets for observing, analyzing and storing information about, and relating to, computer-mediated customer interactions, such as viewing web pages or playing music. The client-side system also includes functionality for defining periodic tasks, such as gathering, analyzing and displaying information on topics of interest, and for direct interaction between the client-side system and the customer.
