Abstract There are disclosed methods and applications for determination of parts of speech (part-of-speech tagging) and noun phrase parsing for text or other non-verbal record of a communication. The part-of-speech tagging method optimizes the product of individual word lexical probabilities and normalized three-word contextual probabilities. Normalization involves dividing by contained two-word contextual probabilities. The method for noun phrase parsing involves optimizing the choices of, typically non-recursive, noun phrases by considering all possible beginnings and endings thereof, preferably based on the output of the part-of-speech tagging method. The disclosed applications include text-to-speechsynthesis and text searching and editing, among a broader range of possible applications.
