Recently educational system, many features control a student’s performance. Students should be well stimulated to study their education. Motivation leads to interest, interest leads to success in their lives. Appropriate assessment of abilities encourages the students to do better in their education. Data mining is to find out patterns by analyzing a large dataset and apply those patterns to predict the possibility of the future events. Data mining is a very critical field in educational area and it provides high potential for the schools and universities. In data mining, there are various classification techniques with various levels of accuracy. This paper focuses to make comparative evaluation of four classifiers such as J48, Naive Bayesian, Bayesian Network and Decision Stump by using WEKA tool. This study is to investigate and identify the best classification technique to analyze and predict the students’ performance of University of Jordan.

This article proposes a remote conversation support system for people with aphasia. The aim of our system is to improve the quality of lives (QoL) of people suffering cognitive disabilities. In this framework, a topic list is used as a conversation assistant in addition to the video phone. The important feature is sharing the focus of attention on the topic list between a patient and the communication partner over the network to facilitate distant communication. The results of two preliminary experiments indicate the potential of the system.

We propose a multi-agent based common framework for interoperability among CAs (Certificate Authorities) from multiple PKI (Public Key Infrastructure) domains to build trust and secure for electronic transactions. Most of the countries recognize PKI as a powerful technique for security services and implemented their own PKI for online user. Several trust models have been used in PKI, and achieving interoperability between them is a major issue which requires recognition of certificates from different domains in order to perform transactions confidently in a cross border application. In our system, User Agent, Trust Agent and Management Agent are created. These software agents co-operate each other for user authentication and authorization processes autonomously in multiple PKI domains within the ASEAN region to encourage the recognition of digital signature to enhance regional market. Our system intended to facilitate not only for matured e-commerce but also for individual start up entrepreneur for secure trading by taking into consideration of regional needs.
