Abstract
A system and methods for enforcing uniform branching of node-to-node inheritance links within semantic networks, to control data flows to and from such networks in conversational applications. Enforced uniform branching criteria converge the population of directly connected nodes of each node toward a small system-wide constant, and converge each sibling inheritance node to a similar level of abstractness, and are also used to select the best candidate tree from a set of competing representation trees within the semantic network. Uniform branching criteria are applied to competing trees for speech recognition, for object recognition in vision systems, for concept recognition in text scanning systems, and for algorithm definition. For speech recognition, phonemes are identified and matched to dictionary nodes in the semantic network. For visual object recognition, object features are identified and matched. For text scanning, words are identified and matched. For speech, visual and text the sets of competing representation trees are formed from alternative combinations of matched dictionary nodes.
