In addition to their ability to reach distant learners, interactive e-learning environments have the potential to make the teaching-learning process more effective. This paper highlights some of the e-learning implementation efforts at the Addis Ababa Institute of Technology (AAiT) in Ethiopia. This case study shows that limited resources do not deter a developing nation from exploiting the pow...

In this document, we describe a light-weighted ontology mediation method that allows users to send semantic queries to distant data repositories to browse for learning object metadata. In a collaborative E-learning community, member data repositories might use different ontologies to control a set of vocabularies describing topics in learning resources. This could hinder the search of learning ...

This paper outlines the development of a learning retrieval agent. Task of this agent is to extract knowledge of the Active Semantic Network in respect to user-requests. Based on a reinforcement learning approach, the agent learns to interpret the user’s intention. Especially, the learning algorithm focuses on the retrieval of complex long distant relations. Increasing its learnt knowledge with...

The model of normal students work placement has been a significant measure for the reform of teacher’s education and with the development of distant education theory; thus the education model of networked learning activities arouses major concern. On the basis of new horizons of learning support service in this paper, it will start from three aspects which are the model of learning support serv...

Niyogi’s book entitled ”The Informational Complexity of Learning” [6] addresses the problem of learning from examples. He considers two distant fields: artificial neural networks and natural language. In both areas he gives a theoretical analysis of informational complexity, i.e. the effects of the size of the leaning set and the number of model parameters on the accuracy of learning depending ...

E-learning enables learners to decide what to learn, when, how and how fast. In the blended e-learning paradigm, knowledge is delivered using a combination of online and traditional distant education practices. The purpose of this paper is to propose a set of criteria for the evaluation of the educational process in blended e-learning communities. The systematic surveying and evaluation of the ...

introduction: endometrial cancer is the most common pelvic malignancy in women. approximately 7,000 women die from this disease every year. although most patients can be treated with appropriate therapies, there is insufficient data regarding the choice of the best adjuvant therapy after a surgical procedure in advanced endometrial cancer cases. it seems that radiotherapy or chemotherapy alone ...
