This project assesses the feasibility of creating a voluntary, nationwide data dictionary that can be used to standardize the reporting of postsecondary accountability reporting requirements for the Carl D. Perkins Career and Technical Education Act of 2006 (otherwise known as Perkins IV). Variables, field codes, and programming instructions,…

Identifies requirements for representing structural aspects of nonconventional information system applications and demonstrates how recursive data models support information systems better than record-based database modelling tools. Structural concepts for representing office data objects are discussed and applied to an office example. Language…

Briefly surveys the numerous applications of fuzzy set theory on data representation and information retrieval. The importance of fuzzy set theory with respect to information systems is illustrated with a bibliography of 86 papers that describe data systems that are somehow "fuzzy." (Author/EM)

The growth in computing power available to institutional researchers today is more than matched by the increase in the demand for information. A significant part of this demand involves minor variations of a few routine questions. Nearly all administrators from the vice president to the department chairman want information about "their"…

Arizona State University has created longitudinal student files capable of tracking each student's curricular and financial aid history from entry until graduation. The structure of the files, their creation and maintenance, and their evolution over the years are described. Uses of the files to conduct different kinds of studies to inform…

This manual on microcomputer-based database management programs provides a description of the key characteristics of database software as well as guidelines for designing a database, uses of database programs, and selecting the right software. Three sets of concepts related to database management are listed and explained: creating a database,…

This study examines the integration of heterogeneous bibliographic information resources from geographically distributed locations in an automated, unified, and controlled way using abstract data types called "classes" through the Message-Object Model defined in Smalltalk-80 software. The concept of achieving data consistency by…

This research project was motivated by results of earlier work (Katzer et al., 1982) on the overlap among document representations. In the earlier study, one representation used in the INSPEC database proved to perform unexpectedly well in comparison with other commonly used representations, such as controlled vocabulary or free-text terms from…

Information is provided on the data sources and tools used in-house at the National Center for Higher Education Management Systems (NCHEMS). The objective of the guide is to serve as a central resource for the various data management and analysis activities of NCHEMS. Summaries are provided of NCHEMS information and analytic resources including…

Discusses data model role in an office filing facility, office data model requirements, and various modelling paradigms for office data modelling. Data model application to a typical collection of office data is presented, filing and retrieval operations are illustrated, and proposed research into other office data modelling aspects is outlined.…

The Educational Research Forum on the CompuServe communication network consists of three parts. The online conferencing area enables users to communicate by typing messages. Communication may be private or stored in the electronic journal for other users to read. The bulletin board, or electronic mail, enables users to send or receive messages.…

Describes a prototype natural language text knowledge system (TKS) that was used to organize 50 pages of a handbook on artificial intelligence as an inferential knowledge base with natural language query and command capabilities. Representation of text, database navigation, query systems, discourse structuring, and future research needs are…

The objective of the unified database (UDB) program was to develop an automated information system that would be useful in the design, development, testing, and support of new Air Force aircraft weapon systems. Primary emphasis was on the development of: (1) a historical logistics data repository system to provide convenient and timely access to…

Presents data model based on text data model (TDM), universal relation model, and nonfirst normal form (NFNF) relations, and discusses applicability to text processing and document retrieval systems. Highlights include database technology applied to information retrieval, NFNF and universal relation, and TDM integration with NFNF universal…

The Hepatitis Knowledge Base (text of prototype information system) was used for modifying and testing "A Navigator of Natural Language Organized (Textual) Data" (ANNOD), a retrieval system which combines probabilistic, linguistic, and empirical means to rank individual paragraphs of full text for similarity to natural language queries…
