Abstract: Systems and methods of handling online communication and commerce via a publish/subscribe pattern are described. Publishers and subscribers can post event messages to broadcast or subscribe to subjects of interest. Each event message must contain four required dimensions, namely WHO, WHAT, WHEN and WHERE. The system will match publishers' and subscribers' events by evaluating all four dimensions for matching conditions. When there are matches, the system will notify users (publishers and/or subscribers). If users respond to events notification, then the system will handle communication and/or commercial transactions.
