Abstract
This paper describes the use of data mining methods in an e-learning system for
providing feedback to courseware authors. The discovered information is
presented in the form of prediction rules since these are highly comprehensible
and they show important relationships among the presented data. The rules will
be used to improve courseware, particularly Adaptive Systems for Web-based
Education (ASWE). We propose to use evolutionary algorithms as the rule
discovery methods, concretely Grammar-Based Genetic Programming (GBGP)
with multi-objective optimization techniques. We have developed a specific tool
named EPRules (Education Prediction Rules) to facilitate and simplify the
knowledge discovery process for usage data in web-based education systems.
Keywords: web usage mining, rule discovery, web-based adaptive education,
evolutionary algorithms, grammar-based genetic programming.
1 Introduction
The application of knowledge discovery techniques and data mining in webbased
education systems is a very novel and promising research area [20]. The
same idea has been successfully used for a long time in e-commerce systems
[15]. But whereas the e-commerce objective is to guide clients in making
purchase decisions, the e-learning objective is to guide students in learning.
Currently there are a lot of tools, both commercial and freeware, to carry out data
mining tasks, and mainly rule discovery. Among all those, DBMiner [21] and
Weka [19] stand out because they are very popular public domain systems and
they have an integrated graphic environment that lets them carry out almost all
data mining tasks. The main inconvenience is that those tools are very difficult to
