Abstract
Method and apparatus are disclosed for the development and implementation of virtual robot's (bot's) directed natural language interaction with computer users. Bots employing the present invention base natural language interaction on a predefined universe of discourse that is decomposed hierarchically into domains. A data structure provides a storage area for each domain. The data structure may reflect the hierarchical decomposition. Domain topics containing program code directing the bot's interaction are placed in domain storage areas. Pattern lists associate words expected to be “heard” by the bot with particular domain topics. Domain topics are provided, as appropriate, to direct a user's attention toward the instant domain's parent, siblings, or children, with lower topics in the hierarchy getting higher preference. Domain censoring and domain tiebreakers improve usability. Universes of discourse developed in accordance with the present invention may advantageously be stored on portable data storage media.
