Graph neural networks (GNN) are vital for analyzing real-world problems (e.g., network analysis, drug interaction, electronic design automation, e-commerce) that use graph models. However, efficient GNN acceleration faces with multiple challenges related to high and variable sparsity of input feature vectors, power-law degree distribution in the…

Sharing user information between systems is an area of interest for every field involving personalization. Recommender Systems are more advanced in this aspect than Intelligent Tutoring Systems (ITSs) and Intelligent Learning Environments (ILEs). A reason for this is that the user models of Intelligent Tutoring Systems and Intelligent Learning…

Information systems are becoming more than computer systems, with new equipment and techniques combining with data processing to form a new field called information technology. The emerging discipline of systems engineering is discussed along with nine systems engineering techniques. An organization chart of an information services department is…

Articles in this issue of "Global Journal of Computer Science and Technology" include: (1) Input Data Processing Techniques in Intrusion Detection Systems--Short Review (Suhair H. Amer and John A. Hamilton, Jr.); (2) Semantic Annotation of Stock Photography for CBIR Using MPEG-7 standards (R. Balasubramani and V. Kannan); (3) An Experimental Study…

The revisions applied to the linear discriminant functions (LDF's) for computerized psychiatric diagnosis are discussed in terms of a comparison of the LDF model with decision tree models. It is concluded that each model has its own advantages and disadvantages. (Author/DEP)

Comprehensive Analytical Methods for Planning in University Systems (CAMPUS) and Computerized Analysis Adapting the Techniques of Simulation to Colleges of Applied Arts and Technology (CAATS)-2 are combined to represent a computer based information and planning system. This system is designed to help the community colleges of Ontario gain the…

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…

This brief text serves as an introduction to the vocabulary, concepts and application of data processing. It is intended to provide the professional educator with a working vocabulary in the areas of: (1) unit record data processing; (2) data processing systems; (3) computer-centered data processing; (4) programing; (5) approaches to data…

A project management system for organizing requests from multiple departments and controlling the workload of the development/maintenance computer staff is described. Practical solutions to deciding project priorities, determining time estimates, creating positive peer pressure among programing staff, and formalizing information requests are…

The purpose of this article is to set forth a conceptual framework to help educational administrators understand the applications and potential of data processing activities in their institutions. It is expected that such a framework will provide a basis for data processing decisions and direction for future data processing activities. The model…

The development and implementation of an institutional framework to guide the management and use of information technologies (computing, office automation, and telecommunications) at Mount Royal College in Calgary, Alberta, are described. (Author/MLW)

Beginning January 1, 1969, Systems Research Group (SRG) undertook a project to develop operational cost simulation models of three of the colleges of applied arts and technology in Ontario. These models, and the data needed to feed them, have been developed and are now operating. SRG describes their progress to date and identifies the remaining…

A computer-assisted financial aid system used at Eastern Connecticut State College is outlined as an example of how a data system can be utilized on a small campus. It can provide foolproof accountability, up-to-date information, efficient turn-around time, and overall improvement of program administration. (Author/LBH)

The decision support system (DSS) environment, the functional requirements of a DSS, and the architectural requirements of the computer systems and communications network necessary to support a DSS are discussed. Changes in the computing environment that are necessary to implement decision support systems are suggested. (Author/MLW)

A scheme which classifies the instructional applications of computers is designed to overcome the confusion created by the imprecision and equivocation associated with computer terminology. The classification is restricted to instructional applications, allows that some applications could apply to more than one category, and reflects a continuum…
