Recommender systems have been actively used in many areas like e-commerce, movie and video suggestions, and have proven to be highly useful for its users. But the use of recommender systems in online learning platforms is often underrated and less likely used. But many of the times it lacks personalisation especially in collaborative approach…

Purpose: The purpose of this paper is to develop a test for data centres, repositories and archives to determine OAIS functional model conformance. The test developed was carried out among the World Data Centre (WDC) member data centres. The method used to develop the OAIS functional model conformance test is discussed, along with the test…

This is one of the outcomes of the work of the Massachusetts Evaluation Service Center for Occupational Education (ESCOE). This publication is intended to serve primarily as a user's guide for facilitators and instructors associated with ESCOE who seek to use and implement the Synthesized Objective Package. Besides a short explanation of the…

Proposes a microprocessor-based architecture that makes large use of parallelism both in processing and in retrieval operations. The proposed system consists of three functional blocks: the query processor, simple query executers, and the answer composer. Twenty-one references are listed. (FM)

Several museum information processing systems are discussed in relation to their underlying assumptions regarding museum information and networking needs that have resulted in inadequate service to some kinds of museums, particularly historical museums. Rather than any of these systems, a modular approach is proposed that would allow each museum…

The NCHEMS Costing and Data Management System is designed to assist institutions in the implementation of cost studies. There are at least two kinds of cost studies: historical cost studies which display cost-related data that reflect actual events over a specific prior time period, and predictive cost studies which forecast costs that will be…

A study was made of the feasibility of establishing a computerized regional information system. Existing systems were reviewed, and the location of the system was discussed. The system's structure was described. A cost benefit analysis looked into capital costs and operating costs. A cooperative system was found to be feasible, based on…

This three-part article introduces a population dynamics model of an information processing system. The first part describes the general model and defines the terms used, the second describes the functional relationships between components, and the third explores the hypothesized emergence of increasingly complex, hierarchical information systems.…

A committee on rules fur cataloging machine readable data files (MRDF) recommends areas for revision of the Anglo American Cataloging Rules to integrate collections of MRDF into the mainstream of bibliographic control. The 12 working papers which support and detail these recommendations are appended to this report. They include rationales for…

Discusses the multilevel information system (MLIS), a retrieval system that integrates functions typical for database management systems and retrieval-oriented systems and provides several levels of data accessing, each developed for a different class of users. Twenty-two sources are cited. (FM)

Discusses the use of optical character recognition (OCR) for inputting documents in an information retrieval system and describes a study that used an OCR-generated database and its corresponding corrected version to examine query evaluation in the presence of noisy data. Scanning technology, recognition technology, and retrieval technology are…

A series of technical reports based on the Aloha System for educational computer programs provide a background on how various countries in the Pacific region developed computer capabilities and describe their current operations, as well as prospects for future expansion. Included are studies on the Japan-Hawaii TELEX and Satellite; computers at…

The reliability and maintainability (R&M) model described in this report represents an important portion of a larger effort called the Digital Avionics Information System (DAIS) Life Cycle Cost (LCC) Study. The R&M model is the first of three models that comprise a modeling system for use in LCC analysis of avionics systems. The total…

The Air Force Logistics Command (AFLC) is revising and enhancing its data-processing capabilities with the development of a large-scale, multi-site, on-line, integrated data base information system known as the Advanced Logistics System (ALS). A data integrity program is to be built around a Data Base Manager (DBM), an individual or a group of…

Suggests new method of external distribution called tree partitioning that involves use of binary tree to split incoming file into successively smaller partitions for internal sorting. Number of disc accesses during a tree-partitioning sort were calculated in simulation using files extracted from British National Bibliography catalog files. (19…
