A computer system is disclosed herein that surveys numerous legal documents which memorialize business or legal transactions and then determines common provisions in such documents. The forms of these “core provisions” are then stored in a knowledge base of the system. The system then allows attorney users to apply the system to analyze unsurveyed documents and use the knowledge base to recognize the core provisions that are most similar to the text of these unsurveyed documents. The user can then edit these unsurveyed documents in a rapid accurate fashion by automated means to revise text to match these core provisions. Document editing functionality is also present, along with means to use correlations to determine the likelihood of the presence/absence of specific provisions and the presence/absence of various particular documents in groups of documents used to memorialize certain types of transactions.
