Abstract
A method for extracting open-issue data from a textual specification using a computer is disclosed. The method includes searching for predetermined trigger token morphemes in an enhanced text corpus based upon the textual specification and constituted of respective enhanced sentences so as to electronically mark respective ones of the enhanced sentences based upon the presence of predetermined trigger token morphemes. Linguistic analysis can then be executed upon each remaining unmarked sentences to detect an interrogatory construct in respective ones of the remaining sentences. Sentences marked based either upon the presence of the trigger token morpheme or upon the presence of the interrogatory construct constitute the open-issue data extracted from the textual specification undergoing analysis.
