An animating system converts a text-based document into a sequence of animating pictures for helping a user to understand better and faster. First, the system provides interfaces for a user to build various object models, specify default rules for these object models, and construct the references for meanings and actions. Second, the system will analyze the document, extract desired information, identify various objects, and organize information. Then the system will create objects from corresponding object models and provide interfaces to modify default values and default rules and define specific values and specific rules. Further, the system will identify the meanings of words and phrases. Furthermore, the system will identify, interpolate, synchronize, and dispatch events. Finally, the system provides interface for the user to track events and particular objects.
