Lockheed Missiles and Space Co., Palo Alto, CA. Electronic Sciences Lab.
THE INVESTIGATION IS CONCERNED WITH THE DEVELOPMENT OF AUTOMATIC INDEXING, ABSTRACTING, AND EXTRACTING SYSTEMS. BASIC INVESTIGATIONS IN ENGLISH MORPHOLOGY, PHONETICS, AND SYNTAX ARE PURSUED AS NECESSARY MEANS TO THIS END. IN THE FIRST SECTION THE THEORY AND DESIGN OF THE "SENTENCE DICTIONARY" EXPERIMENT IN AUTOMATIC EXTRACTION IS OUTLINED. SOME OF THE COMPUTER PROGRAMS NEEDED FOR THIS EXPERIMENT HAVE BEEN COMPLETED--DOCUMENTATION FOR THESE PROGRAMS IS INCLUDED. THE SECOND SECTION IS A DISCUSSION OF AN UNCONVENTIONAL INFORMATION RETRIEVAL SYSTEM WHICH MAY BE USED TO RETRIEVE ENGLISH OR RUSSIAN TECHNICAL LITERATURE. SPECIFICALLY, THERE IS A DISCUSSION OF THE QUERY LANGUAGE AND OF THE DATA BASE STRUCTURE. THE DESIGN OF THIS SYSTEM IS COMPLETE AND PROGRAMMING HAS BEGUN. THE THIRD SECTION COMPRISES A FINAL REPORT IN AN EXHAUSTIVE STUDY OF THE RELATION BETWEEN THE ORTHOGRAPHIC AND PHONETIC FORMS OF ENGLISH MONOSYLLABLES. THE PAPER REPORTS ON THE METHODS AND ACCURACY OF THE ALGORITHM TO MAP THE ORTHOGRAPHIC FORMS OF ENGLISH INTO THE PHONETIC FORM GIVEN BY FIVE DIFFERENT PHONETIC AUTHORITIES, OR TO MAP THE PHONETIC FORM GIVEN BY ONE AUTHORITY INTO THAT FIVEN BY ANOTHER.
