With the rapid development of information technology, various online education platforms support the sharing of digital educational resources. Because digital educational resources are simple to duplicate and disseminate quickly, there exists copyright infringement, which threatens the interests of copyright owners. In addition, the existing…

Networks, such as social networks, are a universal solution for modeling complex problems in real time, especially in the Big Data community. While previous studies have attempted to enhance network processing algorithms, none have paved a path for the development of a persistent storage system. The proposed solution, GraphStore, provides an…

The Inverted File Information Retrieval System (INFIRS), is a document search system which offers a comprehensive range of search facilities. It has been developed at the United Kingdom Chemical Information Service (UKCIS) as a general purpose retrieval tool, suitable for handling a wide variety of data-bases (both free-text and controlled…

Introduces some algorithmic methods, for which no pre-editing is necessary, for automatically "lemmatising" raw text (changing raw text to an equivalent version in which all inflected words are artificially transformed to their dictionary look-up form). The results of a study of these methods, which used a German Text, are also given. (KM)

Educators are constantly looking for the magic bullet--that intervention which will miraculously result in higher achievement scores for students, as well as happier and more productive teachers. The pressure for improvement has caused education to become a "bandwagon" industry. Therefore, educational leaders adopt the latest fad in hopes that it…

The purpose of this article is to describe a system for protecting the anonymity of subjects in longitudinal research and for maintaining the security of data files. The basic system comes from the American Council on Education Cooperative Institutional Research Program. Data is collected from questionnaires, and converted to magnetic tape.…

A pressing and recurrent problem in developing curriculum material is the unnecessary duplication of work done by others; to avoid this, the nine-campus University of California has established a computer data base containing information on all courses and programs being currently offered by the school. (JD)

Response time in large, inverted file document retrieval systems is determined by time required to access files of document identifiers on disk and process a Boolean search request. A specialized computer system has been devised that can perform a complicated sample search involving 70 terms and over 60,000 document references 12 to 60 times…

A bulk data input processor which is available for the Rapidly Extensible Language (REL) English versions is described. In REL English versions, statements that declare names of data items and their interrelationships normally are lines from a terminal or cards in a batch input stream. These statements provide a convenient means of declaring some…

This report delineates the theory and terminology of data compression. It surveys four data compression methods--null suppression, pattern substitution, statistical encoding, and telemetry compression--and relates them to a standard statistical coding problem, i.e., the noiseless coding problem. The well defined solution to that problem can serve…

Analyzes structure of, and data in, the OCLC-MARC record in the form delivered via OCLC's Tape Subscription Service, and outlines important processing functions involved: "unreadable tapes," duplicate records and deduping, match processing, choice processing, locations processing, "automatic" and "input" stamps,…

The report describes an experimental study involving an on-line placement system in Boulder, Colorado which permitted applicants to request information from a terminal on any job stored in the computer. Data were collected on applicants referred by the Employment Service: whether or not hired, reason for not being hired if not hired, applicant…

A relational data system (RDS) is one that has the capability not only to retrieve specific facts but also the ability to deduce facts that are implicit rather than explicit in the data base. The study investigated the application of RDS technology to intelligence data processing. RDS technology and the nature of intelligence data processing are…

A syntax methodology provides a descriptive mechanism to enable machine readable storage and retrieval of numeric data contained in bibliographic documents. The body of this paper treats the nature of "the syntax,""the data element," and the language by which this syntax is expressed. A discussion of the methodology illustrates…

This manual is designed to provide an introduction and basic guide to the use of IBM's Advanced Text Management System (ATMS), the text processing system to be used for the creation of Australian data bases within AUSINET. Instructions are provided for using the system to enter, store, retrieve, and modify data, which may then be displayed at the…
