This study investigates the learners’ attitudes towards using academic, collaborative and social interaction in e-learning portal environment. Academic interaction consists of interaction between learners and online learning resources such as online reading, online explanation, online examination and also online question answering. Collaborative interaction occurs when learners interact among t...

Recommendations in e–commerce collaborative filtering are based on predicting the preference of a user for a given item according to historical records of other user’s preferences. This entails that the interpretation of user ratings are embodied in the prediction of preferences, so that such interpretation should be carefully studied. In this paper, the use of bipolar scales and aggregation pr...

This paper proposes to improve the effectiveness of recommendation items list by taking into account familiarity among customers, in the E-commerce domain. Recently, many online shops are attracted to push type information provision that recommends their items to a customer. Collaborative filtering is one of the representative techniques for such purpose. However, it has mainly discussed recomm...

Information goods pricing is an essential and emerging topic in the era of information economy. Several researchers have devoted considerable attention to developing and testing methods of information goods pricing. Nevertheless, in addition, there are still certain shortcomings and challenges to be overcome. This study encompasses several unexplored concepts that have attracted research attent...

One of the most used approaches for providing recommendations in various online environments such as e-commerce is collaborative filtering. Although, this is a simple method for recommending items or services, accuracy and quality problems still exist. Thus, we propose a method that is based on positive and negative adjustments with its main purpose to improve the quality of the recommendations...

Our main motivation for identifying the metadata present in a collaborative editing service was to offer it through electronic commerce, as we have previously done some work in the definition of electronic commerce of services. In this work we focused in controlling complex services with the help of a workflow [1] for offering them through electronic commerce. We have also identified the metada...

In this paper, we introduce an e-collaborative learning circles methodology which utilizes the information and communication technologies (ICTs) in e-educational processes. In e-collaborative learning circles methodology, the teachers and students announce their research projects on various mailing lists and discussion boards using available ICTs. The teachers & moderators and students who are ...

This research concerns the representation issue in collaborative learning environments Our basic claim is that knowledge representation is not only fundamental to machine learning as shown by AI researchers but also essential to human learning in particular human metalearning few existing learning support systems however provide represen tations which are intended to help the learner make sense...

Despite their demonstrated potential through a range of early studies, on-line collaborative learning systems do not yet have the impact that many believe is possible. In particular, collaborative learning approaches cannot be readily applied to every e-learning experience, since they require a degree of presence and/or collaboration which may be difficult to achieve. In addition, collaborative...
