Abstract: A recommendation system includes a rule system for which defined recommendation system interfaces are available. The recommendation system interfaces are used in the action portion of predicate-action rules in the rule system to invoke non-rule-based systems. The non-rule-based systems provide recommendations to the rule system based on information passed to the non-rule-based systems on invocation and based on data made available to the non-rule-based systems. The rule system establishes a event-listener connection with the non-rule-based system to provide a data feed to the non-rule-based system.

Abstract: The invention relates to marketing page elements (MPEs) used to achieve separation between tasks relating to the design of a web page with marketing content and the design of a means for determining what marketing content should be presented to viewers of the web page. In the preferred embodiment of the invention, a marketing page element comprises multiple marketing page element items. Data items are stored in the marketing page element, and at least one data item is associated with a marketing page element item, the data items having been selected for presentation on the web page by a marketing content selection system in accordance with a marketing strategy. Web page elements, each being connected to a marketing page element item and capable of presenting an associated data item stored in the marketing page element, can be arranged on a web page during the web page's design, without regard for the manner in which data items are to be selected by the marketing content selection system.
