The purpose of this project was to create a machine-readable format for genealogical data. The Library of Congress MARC (Machine Readable Cataloging) bibliographic system was used as the pattern in producing the format. Tags and codes were used to uniquely identify the components of the record for computer manipulation. The resultant structure,…

This research is designed to fulfill the need of scholars, teachers, and developers of teaching materials who are active in the study and compilation of Russian textbooks. Through computer processing, the idioms were classified on the basis of pertinent linguistic criteria, including phonological, morphological, and syntactic information. Included…

The computational model of question answering proposed by a computer program, QUALM, is a theory of conceptual information processing based on models of human memory organization. It has been developed from the perspective of natural language processing in conjunction with story understanding systems. The processes in QUALM are divided into four…

This is a progress report on a project attempting to design a system of compacting text for storage appropriate to disc oriented demand searching. After noting a number of previously designed methods of compression, it offers a tentative solution which couples a dictionary of most frequent character-strings with a set of variable-length codes. The…

A design for network control software for a computer network is described in which some nodes are linked by a communications satellite channel. It is assumed that the network has an ARPANET-like configuration; that is, that specialized processors at each node are responsible for message switching and network control. The purpose of the control…

The computer language FOL is intended to facilitate the implementation of file organizations for information storage and retrieval systems. In many information storage and retrieval applications the designer, initially, does not know how best to organize a data base for efficient retrieval and ease of updating and modifying. It is felt that FOL…

This report describes several of the design decisions underlying ACT, a production system model of human cognition. ACT can be considered a high level computer programming language as well as a theory of the cognitive mechanisms underlying human information processing. ACT design decisions were based on both psychological and artificial…

Divided into five major sections, this paper describes a new algorithm which has been implemented in an extended FORTRAN program which runs on a CDC 6500 computer. The first section of the paper briefly outlines the goals of network analysis and presents the context in which these goals must be met. Section 2 describes the algorithm and the…

This research is part of a series of studies, in which the long term objective is to use computer-assisted instruction (CAI) to teach students how to solve nonroutine problems, i.e., problems in which the problem solvers must generate their own strategies. The subjects were 93 first and third graders who tried to solve a novel reasoning problem on…

The aims of the first phase of the Statistics Indexing and Retrieval (STIR) Project have been: (1) to define the types and sources of statistics which should be within the scope of an operational indexing system for statistical sources; (2) to analyze the use made of statistical sources; and (3) to consider the intellectual, structural, and…

The problem of quality service assurance in a computer networking environment is addressed. In the absence of any direct, well-defined, quantitative measure of service quality and reliability, error collection and analysis is the only basis for service quality control. Therefore, mechanisms are described which facilitate reporting of operational…

The goal of the present project was to identify the types of knowledge necessary and useful for competent troubleshooting/debugging and to examine how new approaches to formal instruction might influence the attainment of competence by students. The research focused on the role of general strategies in troubleshooting/debugging, and how they might…

The purposes of this study were to determine the nature of human semantic memory and to obtain knowledge usable in the future development of computer systems that can converse with people. The work was based on a computer model which is designed to comprehend English text, relating the text to information stored in a semantic data base that is…

The computational complexity of a formal process for the construction of term classes for information retrieval is examined. While the process is proven to be difficult computationally, heuristic methods are applied. Experimental results are obtained to illustrate the maximum possible improvement in system performance of retrieval using the formal…

Language teaching requires textbook material that contains the most frequent concepts of a language. The computer brings its tremendous information processing ability to the task of establishing word frequency rankings, but the computer is limited to counting word-forms and not semantic concepts. The most recent word frequency dictionaries, in…
