We describe a multimodal analysis based automated triggering mechanism for automated filtering and reactivity based on the content of multiple multimedia channels over the World Wide Web. The trigger description language supports complex conditions connected through Boolean operators (logical OR, logical AND, and negation), temporal and frequency of occurrence constraints and actions. A trigger can be placed either at the client end or at the server end. We present a grammar for an XML based trigger description language, and it's corresponding implementation. Performance analysis has been presented.
