PARSER FOR NATURAL LANGUAGE TEXT

An improved natural language text parser is disclosed which provides syntactic analysis of text using a fast and compact technique. Sequential steps of word isolation, morphological analysis and dictionary look-up combined with a complement grammar analysis, are applied to an input data stream of woods. Word expert rules, verb group analysis and clause analysis are then applied to provide an output data structure where the words in the input data stream are associated with appropriate phrase markings. The principle of operation of the parser is applicable to a variety of Indo-European languages and provides a faster and more compact technique for parsing in a data processor than has been available in the prior art.
