This is the final scientific research report for the research in programing at Carnegie-Mellon University during 1968-1970. Three team programing efforts during the past two years have been the development of (1) BLISS--a system building language on the PDP-10 computer, (2) LC2--a conversational system on the IBM/360, and L*--a system building…

The major purpose of this study was to investigate expressive content language differences in preschool black children that might relate to Piaget's theory of egocentric speech. Correlating first order Harvard III Psycho-sociological Dictionary categories with Piaget's egocentric speech and the second order categories with socialized speech it was…

Provided in this report are substantive summaries of the papers presented and discussions held at the Spring 1973 conference convened by EDUCOM, the Interuniversity Communications Council. The general focus is upon issues and obstacles related to the development of national computer networks in higher education; these networks have become more and…

Although the indispensibility of access control mechanisms in data secure systems has been recognized, there is a need for more subtle protection and refined control mechanisms. This report describes context protection mechanisms which enable the same data unit to be protected differently in different contexts, the differences being determined by…

The results of various computerized coding techniques used to identify persons of Spanish derivation were compared to questionnaire responses in which people identified themselves as Spanish. The coding techniques classified names as Spanish and non-Spanish using the following: census surnames; Morton surnames; "Broad" Spanish surnames; "Narrow"…

This conference provided an opportunity for those interested in the delivery of computer services to universities to gain a better perspective of computer technology in education, in a context of financial crisis and structural change. The focus was upon five broad areas. The first of these dealt with the role of the computer in a changing…

Ways of making the natural language of unsophisticated computer users meaningful to the computer are discussed. The discussion is set within the context of the Rapidly Extensible Language (REL) System, a question answering system with underlying relational data bases. Major topics covered include individuals and predicates, the problem of verbs,…

The report presents a summary of science information research activities of the School of Information and Computer Science, Georgia Institute of Technology. Included are project reports on interrelated studies in science information, information processing and systems design, automata and systems theories, and semiotics and linguistics. Also…

Two papers are included in this report. "Control and Feedback in the Environment of a Computer Tutor" investigates some control and feedback properties of a tutorial environment comprised of a student, his computer tutor, and the designer of the computer tutor. Three classes of computer tutor are described: rigid, generative, and knowledgeable.…

This dissertation reports on general computer service characteristics for California public junior colleges; identifies aspects of organization and administration likely to affect computer service effectiveness; determines relationships between patterns of organization and administration, and the effectiveness of computer services; and proposes…

This study involved two phases: first when classification was based on the calibration sample, and second in a cross-validation setting. Computer-generated data were used. Results obtained from rules based on probabilities of group membership were compared for accuracy when classifying in the discriminant space and in the predictor variable…

The Fall, 1972 conference of EDUCOM focused on problems, potentials, and current activities related to the development of interinstitutional cooperation through computer networking. In these proceedings, a number of representative networking attempts were presented, discipline-oriented workshops discussed possibilities in a number of different…

This bibliography is the result of an intensive search through all available indexing and abstracting sources in the fields of library science, information science, documentation and computer science. The purpose is to support an investigation into the nature of an information worker and provisions for his education. The basis of selection was…

In an attempt to overcome the lack of natural means of communication between student and computer, this thesis addresses the problem of developing a system which can understand natural language within an educational problem-solving environment. The nature of the environment imposes efficiency, habitability, self-teachability, and awareness of…

An important development in the computerization of society is the development of the ability to communicate with a computer through human speech. Speech recognition machines with limited capabilities are available today. (BB)
