SCIENTIFIC REPORT NO. 1 OF THIS PROJECT CONTAINS FOUR PARTS. THE FIRST, BY P. ROSENBAUM AND D. LOCHAK, PRESENTS AND EXPLAINS THE "IBM CORE GRAMMAR OF ENGLISH" AND GIVES A SET OF 66 DERIVATIONS CONSTRUCTED IN TERMS OF THE CORE GRAMMAR. PART II, "DESIGN OF A GRAMMAR TESTER" BY D. LIEBERMAN, SUMMARIZES THE DESIGN CONSIDERATIONS OF THE TESTER AND PRESENTS A SET OF TENTATIVE INPUT, OUTPUT, AND CONTROL FORMATS. "PROGRAMMING OF THE GRAMMAR TESTER" BY F. BLAIR, PART III, DESCRIBES THE IMPLEMENTATION OF A PROCESS FOR COMPILING AND UPDATING TRANSFORMATIONAL GRAMMARS AND A PROCESS FOR TESTING SUCH GRAMMARS. BOTH PROCESSES ARE WRITTEN IN LISP 1.5. PART IV BY D. LIEBERMAN AND D. LOCHAK IS ENTITLED "COMPUTER SUPPORT FOR LEXICON DEVELOPMENT AND USE." A PROGRAM PACKAGE (PROGRAMMED IN SNOBOL) IS DESCRIBED WHICH FACILITATES THE COMPILATION, MODIFICATION, SCANNING, AND OTHER CLERICAL PROCESSES NECESSARY FOR THE DEVELOPMENT OF A LEXICON TO BE USED IN A TRANSFORMATIONAL GRAMMAR. THE "FINAL REPORT" OF THIS RESEARCH PROJECT IS DESCRIBED IN ED 010 874.
