Discusses the design and implementation of database management systems for low-organized and natural language text on small computers. Emphasis is on the efficient storage and access of primary (text) and secondary (dictionary) files. Possible expansions to the system to increase its use in linguistic research are considered. (six references)…

Introduces two distribution schemes that partition documents over multiple processors and the corresponding multiprocessor retrieval algorithms that match relevant documents to user queries. The suggested framework is based on a general purpose hypercube multicomputer architecture with a dedicated disk for each node. A timing analysis for the…

Compares two models used for text storage and retrieval systems, the text model and the relational model. Characteristics of documents and document collections are discussed, trends in document processing are described, and future directions of document management systems are suggested. (20 references) (LRW)

Discusses traditional information retrieval through indexing terms and describes a document storage and retrieval system based on structured information, where the SGML document is transformed into Grove (Graph Representation of Property Values) and stored at an element level by an object-oriented database management system. Also discusses query…

Distance education created new challenges regarding the delivery of large size isochronous continuous streaming media (SM) objects. In this paper, we consider the design of a framework for customized SM presentations, where each presentation consists of a number of SM objects that should be retrieved and displayed to the user in a coherent…

A tutorial introduction to data models in general is provided, with particular emphasis on the relational and network models defined by the two proposed ANSI (American National Standards Institute) database language standards. Examples based on the network and relational models include specific syntax and semantics, while examples from the other…

Gives an overview of MEDLARS II as an example of a major bibliographic processing system that supports on-line access to a number of very large files, has efficient throughput, and is operated on a single large-scale computer. (Author/PF)

THE CENTER WAS ESTABLISHED TO COLLECT, ABSTRACT, SYNTHESIZE, PRODUCE, STORE, AND DISSEMINATE CAREER INFORMATION TO HIGH SCHOOLS AND JUNIOR COLLEGES IN SAN DIEGO COUNTY, CALIFORNIA. A STUDY WAS MADE TO DETERMINE THE TYPE OF CAREER INFORMATION DESIRED BY STUDENTS AND COUNSELORS. THE INFORMATION WAS PUT ON MICROFILM APERTURE CARDS. EACH CARD CONTAINS…

GENERAL CONSIDERATIONS INVOLVED IN THE DESIGN OF FILE ORGANIZATIONS FOR INFORMATION RETRIEVAL SYSTEMS ARE DISCUSSED. THE QUESTION OF INVERTED FILE AND SERIAL FILE SEARCHING ON MAGNETIC TAPE IS REVIEWED. BASED ON FORMULAS CONCERNING INDEX TERM USAGE, IT IS SHOWN FOR A SPECIFIC COLLECTION THAT SEARCHING THE SERIAL FILE IS MORE EFFICIENT THAN…

THIS PROJECT SOUGHT TO DEVELOP AN OPERATIONAL "TOTAL" DATA SYSTEM FOR AN INSTITUTE OF HIGHER EDUCATION. THE REPORT SYNTHESIZES MANY PREVIOUS EXPERIENCES IN DATA PROCESSING, IN ORDER TO PRESCRIBE A MANAGEMENT INFORMATION SYSTEM SUITED TO COLLEGES AND UNIVERSITIES. IT WAS FELT THAT A BROAD BASE, GENERAL PURPOSE INFORMATION SYSTEM WOULD…

This manual presents detailed descriptions and examples of standards and techniques for formatting and documenting machine-readable data files. The descriptions of syntax and stylistic elements are independent of whether documentation is produced manually or as a machine-readable text file. The manual also discusses rules of good practice for…

The author proposes a system using the HUC to identify all information and knowledge which can be reduced to a written, pictorial, oral, or machine readable record. The code designations, which may consist of letters, numerals, and other symbols and which average 12 to 18 characters in length, provide information in 12 fields: type of material,…

System Development Corporation's (SDC) exploration of microform state-of-the-art and current research reveals developments which will be applicable to the requirements of many small Department of Defense (DoD) users and similar facilities in the next two to five years. The study's survey of the small user population reveals a variety of user…

IBM's Administrative Terminal System (ATS) is an effective data collection device, but its searching capabilities are severely limited. Searching an ATS document line-by-line is a time consuming process requiring slow printout speeds. A search can operate only upon 9,999 lines of text at any one time. Working storage limitations make it necessary…

Search theory, originally developed for antisubmarine search, is applied to the scanning of library shelves for books of interest, or of a computerized abstract catalog for items of immediate application. Procedures optimizing the information to be found are discussed, as well as methods whereby the operational parameters can be measured. The…
