Abstract
An apparatus and method for the identification of noun phrases in a stream of natural language text receives an input stream of text, identifies tokens within the stream of text, and processes the tokens to identify noun phrases. The system processes the tokens by annotating the tokens with tags identifying characteristics of the tokens and by contextually analyzing each token and its associated characteristics. During processing, the system can also disambiguate individual token characteristics and identify agreement between tokens.
