The objective of the current work program is to develop an on-line computer capability that would assist an information analyst in processing textual materials. The initial result of the work program is the design of a system for text processing and a computer implementation of a preliminary model of the system that strongly supports the validity…

In order to carry out its project for a mechanized documentation service based on a system of keyword coordination, European Atomic Energy Community's Centre for Information and Documentation was led to draw up an inventory of terminology in the nuclear field and maintain a tight control over it. A basic thesaurus of 1230 keywords was drawn up and…

Large-scale, on-line information storage and retrieval systems pose numerous problems above those encountered by smaller systems. A step toward the solution of these problems is presented along with several demonstrations of feasibility and advantages. The methodology on which this solution is based is that of a posteriori automatic classification…

The task of administrative decision makers at diverse and complex institutions has been made more difficult with student confrontations, and there is an expressed need for improved tools to assess student attitudes and characteristics. The Campus Environment Scale (CES), a data-gathering tool, contains 150 statements that deal comprehensively with…

This paper reports an experiment in on-line retrieval using man-machine dialogue on a remote console. Message editing procedures and the use of two command languages are described. The system employs a PDP-8 computer for generating, proofreading, and editing messages, and an IBM 7040 computer for information retrieval processing. The symbolic…

Three related activities are reported in this study. One is the development of two data banks designed to supply children with information about many aspects of life in world culture. The entire data bank system was piloted by second-grade, middle-class children with self-administering orientation units developed to introduce students to the data…

Three indexes to a collection of 3204 documents in the field of chemistry were test searched. The indexes are a keyword from title index without added keywords, a keyword from title index with added keywords, and a single access point per document alphabetic subject index. The three indexes were searched by 14 graduate chemistry students with 66…

Two essential components of the information-logic problem are: (1) choosing some known part of the total information block for parallel review of the entire block and (2) parallel logic processing of a sequence of codes. The described device fulfills these essential components thereby improving information processing and increasing the speed of…

Working toward the goal of an automatic indexing system which is truly competitive with human indexing in cost, time and comprehensiveness the Machine-Aided Indexing (MAI) process was developed at the Defense Documentation Center (DDC). This indexing process uses linguistic techniques but does not require complete syntactic analysis of sentences…

The volume of international marine sciences literature, estimated at 25,000 citations for 1968, is increasing at the rate of up to 20% per year. In view of the limited availability to users of the present and future backlog of information, there is an immediate need to systematically organize and process this material through sophisticated…

Researchers make little or no use of formal information systems. This is due, not so much to 'information apathy' on their part, as to faults inherent in information services as a whole. A formal information service may not come through at all. It is not capable of reaching behind a request to the real question that motivated it. By not being able…

A description is provided of a conceptual model for a data secure system. The discussion first offers a formal working vocabulary and next, using the intuitive idea of a dichotomy between permissible and impermissible accesses, formalizes the idea with an Extended Logical Data Base and with protection specifications and patterns. These…

As a recent curriculum innovation replacing Freshman English, the Freshman Investigative Seminar consists of 12 or 13 students meeting for one semester of five weekly class hours, directed by faculty from different disciplines. Its objectives are to lead the student to learn how to gather information from various sources, how to keep accurate…

Rooted binary trees with weighted nodes are structures encountered in many areas, such as coding theory, searching and sorting, information storage and retrieval. The path length is a meaningful quantity which gives indications about the expected time of a search or the length of a code, for example. In this paper, two sharp bounds for the total…

The publication of papers describing activity in computer-based storage and retrieval and geoscience information has continued at a vigorous pace since release of the last bibliography, which covered the period 1946-69 (ED 076 203). A total of 211 references are identified, nearly all of which were published during the three-year period 1970-72…
