Abstract
In the method of extraction, the words of the text are encoded by comparing them with the contents of a lexicon of tool words (essentially articles, prepositions, conjunctions, and verbal auxiliaries), and nominal groups are then identified by searching subsets of the resulting succession of encoded words to look for groups of encoded words that comply with predefined syntactical rules.
