Web Intelligence is a direction for scientific research that explores practical applications of Artificial Intelligence to the next generation of Web-empowered systems. In this paper, we present a Web-based intelligent tutoring system for computer programming. The decision making process conducted in our intelligent system is guided by Bayesian networks, which are a formal framework for uncertainty management in Artificial Intelligence based on probability theory. Whereas many tutoring systems are static HTML Web pages of a class textbook or lecture notes, our intelligent system can help a student navigate through the online course materials, recommend learning goals, and generate appropriate reading sequences.

Based on the requirements arising from process-centered organizations and because of the lack of process modeling mechanisms in traditional software development methods, this paper presents a Business Process-centered Software Analysis method (BPSA), which supports the modeling of business process control logic. As a method, BPSA is composed of two main parts: a model and the steps of how to model the requirements using this model. The model includes the functional, informational and organizational aspects as well as the behavioral aspect that provides the mechanism for modeling the process control logic. The event mechanism is employed in this method as a main technique for modeling the control aspect of business processes. This method is based on technologies such as Structured Analysis, OOA & OOD, Workflow, XML, and has been used in the development of several medium and large information systems, proving to be both useful and effective.

This paper describes the effect that the introduction of computing laboratory facilities has had on the curriculum of an undergraduate Computer Science program. From its initial use by only one course, the laboratory has grown gradually both in terms of equipment and involvement with the Department's teaching program. Demands placed on the laboratory by various courses have influenced the acquisition of new equipment. Conversely, with the addition of new and varied equipment, it was possible to incorporate the laboratory into more courses. The Paper describes this interplay between the development of the laboratory and the growth of the Department. Problems such as maintenance and support staff for the laboratory are discussed whenever they have affected decisions on the use of the laboratory by a course or the selection of equipment.

The development of display procedures for drawing pictures of linear graphs is described. The facility to model relationships pictorially has led to the use of graph theoretic techniques in many different applications. While computers normally work with a numeric representation of a graph such as its incidence matrix, manual transformation of such representations into pictures is a tedious process. An interactive graphics system has been developed which, through a combination of heuristic techniques and semi-automatic procedures, creates visual representations of graphs with a minimum of user intervention. The resultant pictures display mirror-image and rotational symmetries that occur within the graph. This very general approach of displaying symmetry in graphs has proven useful in studies of several classes of graphs. However, the system is primarily a research tool designed for use by mathematicians and graph theorists. Difficulties entailed in adapting the display procedures to more specific application areas are discussed.
