Ambiguous Data

Despite significant progress in e-learning technology over previous years, in view of huge sizes of data and databases, efficient knowledge extraction techniques are still required to make e-learning effective tool for delivery of learning. Rough set theory approach provides an effective technique for extraction of knowledge out of massive data. In order to provide effective support to learners, it is essential to know individual style of learning for each learner. For determining learning style of each learner, one is required to extract essentials of style of learning from a large number of parameters including academic background, profession, time available etc. In such scenario, rough theory proves a useful tool. In this paper, a rough set theory approach is proposed for determining learning styles of learners efficiently, so that based on the style, a learner may be provided learning support on the basis of requirement of the learner. These is achieved by eliminating redundant and ambiguous data and by generating reduct set, core set and rules from the given data. The results of this study are validated through RSES software by using same rough set analysis.

Extracting knowledge through the machine learning techniques in general lacks in its predictions the level of perfection with minimal error or accuracy. Recently, researchers have been enjoying the fruits of Rough Set Theory (RST) to uncover the hidden patterns with its simplicity and expressive power. In RST mainly the issue of attribute reduction is tackled through the notion of ‘reducts’ using lower and upper approximations of rough sets based on a given information table with conditional and decision attributes. Hence, while researchers go for dimension reduction they propose many methods among which RST approach shown to be simple and efficient for text mining tasks. The area of text mining has focused on patterns based on text files or corpus, initially preprocessed to identify and remove irrelevant and replicated words without inducing any information loss for the classifying models later generated and tested. In this current work, this hypothesis are taken as core and tested on feedbacks for elearning courses using RST’s attribution reduction and generating distinct models of n-grams and finally the results are presented for selecting final efficient model

Recent research makes wide efforts on attribute selection methods for making effective data preprocessing. The field of attribute selection spreads out both vertical and horizontal, due to increasing demands for dimensionality reduction. The search space is reduced very much by pruning the insignificant attributes. The degree of satisfaction on the selected list of attributes will only be increased through verification of more than one formal channel. In this paper, we look for two completely independent areas like Rough Set theory and Data Mining/Machine Learning Concepts, since both of them have distinct ways of determining the selection of attributes. The primary objective of this work is not only to establish the differences of these two distinct approaches, but also to apply and appreciate the results in e-learning domain to study the student engagement through their activities and the success rate. Hence our framework is based students’ log file on the portal page for elearning courses and results are compared with two different tools WEKA and ROSE for the purpose of elimination of irrelevant attributes and tabulation of final accuracies.

One of the challenges in personalized e-learning research is how to find the unique learning strategies according to a learner’s personality characteristic. A learner’s personalitycharacteristic may have many attributes, and all of them may not have equal values. Correlation analysis, regression analysis, discriminator function, and educational psychology have been used to find solutions, but these methods have their shortcomings. This article proposes an improved approach based on rough set theory to find thekey personality attributes and evaluates the importance of these attributes. The approach has been successfully used in the actual e-learning environment for a major research university in China.
