Abstract
A dictionary-based data compression technique wherein compression occurs at a variety of levels in response to word, phrase, super-phrase (sentence), and context-sensitive recognition. A separate dictionary is used at each compression level so that word compression occurs first, followed by phrase compression, followed by other compressions. Disclosed applications built upon the compression strategy include an idiomatic-language translator and a voice-recognition control system.
