Described and illustrated is the use of the computer program GRADER which returns a letter grade and rank for students. (MB)

An introduction into the foundations of constructing a marketing data base is presented for the systems and marketing executives who are familiar with basic computer technology methods. The techniques and concepts presented are now being implemented by major organizations in the development of Management Information Systems (MIS). A marketing data…

The broad objective of this investigation was to explore the potential and applicability of automatic methods for the indexing of drug-related information appearing in English natural language text and to find out what can be learned about automatic indexing in general from the experience. More specific objectives were the development,…

The construction cost estimate, often expressed as an absolute cost, leads to misunderstanding between client, designers, and builders. If estimates are to be used as adequate cost indicators, their probabilistic nature must be recognized and they must be expressed not as absolute numbers but in terms of a number with some indication of the…

A signature tree is a binary decision tree used to classify unknown patterns. An attempt was made to develop a computer program for manipulating signature trees as a general research tool for exploring machine learning and pattern recognition. The program was applied to the problem of speech recognition to test its effectiveness for a specific…

The need for traps, a program routine which checks the validity of the user's response to the computer's request for input, in Computer Assisted Learning Packages, is discussed. Several example traps are described. (MK)

In the last decade, a modeling technique has been developed to handle complex input/output analyses where outputs involve joint products and there are no known mathematical relationships linking the outputs or inputs. The technique uses the geometrical concept of a six-dimensional shape called a polytope to analyze the efficiency of each…

Describes computer program which converts text of user input and system responses from online search system into fixed format records describing interaction. Query language syntax, format of output record produced by parser, problems in constructing parser, its performance characteristics, and recommendations for improving process of logging…

Objectives of this project were to develop and test a method for automatically processing the text of abstracts for a document retrieval system. The test corpus consisted of 768 abstracts from the metallurgical section of Chemical Abstracts (CA). The system, based on a subject indexing rational, had two components: (1) a stored dictionary of words…

The report prepared for the Five Associated University Libraries (FAUL) by the Technical Information Dissemination Bureau (TIDB) at Suny-Buffalo is divided into nine sections: (1) a summary of procedures used to accomplish the specified MASFILE-II tasks; (2) a graphic comparison of the MARC-II and the MASFILE-II formats; (3) recommend…

The aim of the CYCLOPS Project research is the development of techniques for allowing computers to perform visual scene analysis, pre-processing of visual imagery, and perceptual learning. Work on scene analysis and learning has previously been described. The present report deals with research on pre-processing and with further work on scene…

ARIS is an artificial intelligence system which uses the English language to learn, understand, and communicate. The system attempts to simulate the psychoneurological processes which enable man to communicate verbally. It uses a modified stratificational grammar model and is being programed in PL/1 (a programing language) for an IBM 360/67…

Misunderstandings on the part of the researcher as to the computer's capability, coupled with the inability of the computer system to function efficiently, has often handicapped the research activities in computer assisted instruction (CAI). A new data system is being developed to resolve these problems. A Delete/Sort program has been designed to…

The logic of the system presented in this report is divided into six parts for computer processing and manipulation. They are: (1) processing of Library of Congress copy, (2) editing of input into standard format, (3) processing of information into and out from the authority files, (4) creation of the catalog records, (5) production of the…

A method was developed for doing a computer simulation of elementary school activities for different school organizations, with traditional and multiunit schools being observed for significant factors relating to the use of space. Analysis of the collected data showed that group size varied significantly as a function of school program and…
