Object-oriented frameworks can be complex. Often, considerable time is needed to understand the framework, including not only what the framework does, but also how to use it. Techniques for documenting the design of a framework already exist, but less work has been done on documenting how to use the framework. We have developed the notion of hooks as a means of representing knowledge about the ...

Education is rapidly evolving from an opportunity that was provided mainly for an elite to one that is available to a mass markets and as such is prone to the forces generated by this environment. Where, in the established pattern, commercial interest was limited mainly to the use of skills developed during the educational process, the future model of educational provision will involve extensiv...

This paper introduces definition and enactment models to characterize workflows. The proposed knowledge model provides concepts for modeling activities, data used by such activities, agents, and ordering operators and synchronization modes used for specifying activities dependencies. The behavior model provides dimensions that characterize workflow enactment. Both models are currently implement...

Scientific Workflow Systems have been developed as a means to enable scientists to carry out complex analysis operations on local and remote data sources in order to achieve their research goals. Systems typically provide a large number of components and facilities to enable such analysis to be performed and have matured to a point where they offer many complex capabilities. This complexity mak...

This paper presents the learner-controlled adaptive group formation technique offered by the web-based adaptive educational hypermedia system MATHEMA. More specifically, this paper describes why we take into consideration the group effectiveness, concerning the concrete-abstract dimension of learners’ learning style, in forming learner groups and how the adaptive group formation algorithm gener...

The detection and handling of data leakages is becoming a critical issue for organizations. To this end, data leakage solutions are usually employed by organizations to monitor network traffic and the use of portable storage devices. These solutions often produce a large number of alerts, whose analysis is timeconsuming and costly for organizations. To effectively handle leakage incidents, orga...

ActiveMath is a web-based intelligent tutoring system for mathematics. This article presents the technical and pedagogical goals of ActiveMath, its principles of design and architecture, its knowledge representation, and its adaptive behavior. In particular, we concentrate on those features that rely on AI-techniques.

Internet and expert systems have offered new ways of sharing and distributing knowledge, but there is a lack of researches in the area of web-based expert systems. This paper introduces a development of a web-based expert system for the regulations of civil service in the Kingdom of Saudi Arabia named as RCSES. It is the first time to develop such system (application of civil service regulation...

M-learning web based applications are a particular case of web applications designed to be operated from mobile devices. Also, their purpose is to implement learning aspects. Project management of such applications takes into account the identified peculiarities. M-learning web based application characteristics are identified. M-learning functionality covers the needs of an educational process....

Several approaches are proposed for retrieving images. Each of them describes image according to application domain requirements. No global approach exists to resolve retrieving image in complex domains (as medical one), in which content is multifaceted. A framework to retrieve medical images is presented. In this paper, we expose our three-dimensional approach applied to medical domain, and re...
