Using Eclipse in building model-driven e-Learning supports

چکیده
In this paper we discuss the role of modelling and of EMF (Eclipse Modeling Framework) and GMF (Eclipse Graphical Modeling Framework) in the design and development of supports for eLearning applications. A model driven approach to eLearning applications is presented, rooted on the explicit representation of the model of the didactic content, based on a metamodel language expressed in Ecore. Besides exploiting the integration of Java, XML and UML provided by EMF, we introduce a Prolog-based representation of models as a more convenient way to overcome the gap between the user level and the technology level and as a mean to reduce the cost of design and implementation of learning strategies. Working in a MDA perspective, the tool exploits GMF and Jet (Java Emitter Templates) to produce code for a knowledge based, SCORM® compliant Platform Specific Model. The content model provides the Platform Independent Model that allows to achieve the intended behavioural semantics.

Enhancing Learning from Imbalanced Classes via Data Preprocessing: A Data-Driven Application in Metabolomics Data Mining
This paper presents a data mining application in metabolomics. It aims at building an enhanced machine learning classifier that can be used for diagnosing cachexia syndrome and identifying its involved biomarkers. To achieve this goal, a data-driven analysis is carried out using a public dataset consisting of 1H-NMR metabolite profile. This dataset suffers from the problem of imbalanced classes...

Building a Bridge between Information Engineering and Model Driven Architecture
The Model Driven Architecture (MDA) approach of OMG aims to automatically derive software from models. Information Engineering (IE) is succeeding to do this with well established industry solutions for more then one decade. IE can be introduced into the MDA world using model transformation such that both of them can profit from each other in a cooperative way. keywords: MDA, MOF, UML, Informati...
