This study investigated the longitudinal trends of e-learning research using text mining techniques. Six hundred and eighty-nine (689) refereed journal articles and proceedings were retrieved from the Science Citation Index/Social Science Citation Index database in the period from 2000 to 2008. All e-learning publications were grouped into two…

Enumerates principal management objectives of database management systems (data independence, quality, security, multiuser access, central control) and criteria for comparison (response time, size, flexibility, other features). Conventional database management systems, relational databases, and database machines used for backend processing are…

Reviews the state of research in text mining, focusing on newer developments. The intent is to describe the disparate investigations currently included under the term text mining and provide a cohesive structure for these efforts. A summary of research identifies key organizations responsible for pushing the development of text mining. A section…

Discusses database structure, concepts, and management systems in library settings and describes the Comprehensive Automated Learning Resource System (CALS). This system was developed by NILRC to meet the needs of libraries which incorporate print and audiovisual materials in their collections. (RAA)

This report describes approaches to database translation (i.e., transferring data and data definitions from a source, either a database management system (DBMS) or a batch file, to a target DBMS), and recommends a method for representing the data structures of newly-proposed network and relational data models in a form suitable for database…

The use of computers in retrieving bibliographic chemical information is traced through the SDI, batch, and online modes, and related changes are noted in such areas as data base availability, cost, software, and amount of user control. The impact of these changes on both the quality and quantity of chemical information use is discussed, as well…

Discusses databases and database management systems and explains how they can be used to organize and provide access to information. Highlights include relational models, database design considerations (particularly normalization), query languages used in programming, screen displays, data integrity and security, and effects of the organizational…

Review of office filing facility filing and retrieval mechanisms for unstructured and mixed media information focuses on free text methods. Also discussed are the state of the art in handling voice and image data, problems with searching text surrogates to implement free text content retrieval, and work of Project Minstrel. (Author/MBR)

Defining a numeric database as a computer-readable collection of data predominantly numeric in nature, this article reviews techniques and technologies having a positive influence on the growth of numeric databases, such as videotex, mini- and microcomputers, artificial intelligence, improved software, telecommunications, and office automation.…

Discusses the developments that have positively or adversely affected abstracting and indexing services over the past several decades, addressing such topics as the impact of computers and the migration from print-on-paper to online information provision. Forecasts for the near and long-term future are made and a reference list is included. (JL)

Surveys the field and literature of geographic information systems (GIS) and spatial data representation as it relates to GIS. Highlights include GIS terms, data types, and operations; vector representations and raster, or grid, representations; spatial indexing; elevation data representations; large spatial databases; and problem areas and future…

Discusses processes involved in development, operation, and utilization of bibliographic databases--design, data collection, processing, access, and use--and assesses their relevance to developing countries. Utilization of other countries' databases, use of services of organizatons in other countries, and participation in a cooperative system are…

This report is based on a questionnaire sent to 32 selected National Archives and on interviews with archivists from eight countries. Geared to the needs of developing countries, the report covers: (1) the impact of computerization on finding aids; (2) advantages and problems of computerization, including enhanced archival control, integration of…

Reviews definitions and the scope, history, technological capabilities, and other significant issues of electronic publishing. Advantages and disadvantages of electronic publishing are compared to those of traditional publishing, and possible future impacts of electronic publishing on books and libraries are considered.
