Abstract
Automated methods are provided for the editing and authoring of topic scripts for the dynamic operation of virtual robots. A virtual robot, or BOT, processes natural language input from a user to effect certain actions according to user input. Typically, BOTs are constructed using topic scripts. Topic scripts may comprise example statements that typify the topic in question and patterns that are matched against user input to determine if the topic is activated by the user input. The steps of one embodiment of the present invention comprise: for an example statement associated with a topic script; testing said example statement against patterns in the topic script to determine if said example statement activates said topic; then for a word in an example statement not activating said topic: identifying zero or more pattern lists matching said word; then choosing one action from among a group of actions comprising: keeping said word; and replacing said word with a pattern list; then adding zero or more revised patterns to said topic script.
