چکیده

In this paper we are going to show how to discover interesting prediction rules in student usage information, and use them to improve adaptive web courses. We have used AHA! to make a course that adapts both the presentation and the navigation depending on the level of knowledge that each particular student has. We have made several changes in AHA! to improve its power in the educational area. We use the logging information from AHA! to discover relations in the usage data (reading times, difficulty levels and test results). The most interesting relations are shown to the teacher so that he can carry out the appropriated modifications in the course to improve it.

Rule mining with GBGP to improve web-based adaptive educational systems

In this chapter we describe how to discover interesting relationships from student’s usage information to improve adaptive web courses. We have used AHA! to make courses that adapt both the presentation and the navigation depending on the level of knowledge that each particular student has. We use data mining methods for providing feedback to courseware authors. The discovered information is pr...

A Genetic Algorithm For Discovering Interesting Fuzzy Prediction Rules: Applications To Science And Technology Data

Data mining consists of extracting knowledge from data. This paper addresses the discovery of knowledge in the form of prediction IF-THEN rules, which are a popular form of knowledge representation in data mining. In this context, we propose a new Genetic Algorithm (GA) designed specifically for discovering interesting fuzzy prediction rules. The GA searches for prediction rules that are intere...

A Distributed-Population Genetic Algorithm for Discovering Interesting Prediction Rules

In data mining the quality of prediction rules basically involves three criteria: accuracy, comprehensible and interestingness. The majority of the rule induction literature focuses on discovering accurate, comprehensible rules. In this paper we also take these two criteria into account, but we go beyond them in the sense that we aim at discovering rules that are interesting (surprising) for th...

Prediction Mining - An Approach to Mining Association Rules for Prediction

An interesting application of association mining in the context temporal databases is that of prediction. Prediction is to use the antecedent of a rule to predict the consequent of the rule. But not all of association rules may be suitable for prediction. In this paper, we investigate the properties of rules for prediction, and develop an approach called prediction mining — mining a set of asso...
