摘要:Recent technological advances have led to tremendous capacities for collecting, storing and analyzing
data being created at an ever-increasing speed from diverse sources. Academic institutions which offer
open and distance learning programs, such as the Hellenic Open University, can benefit from big data
relating to its students’ information and communication systems and the use of modern techniques and
tools of big data analytics provided that the student’s right to privacy is not compromised. The balance
between data mining and maintaining privacy can be reached through anonymisation methods but on the
other hand this approach raises technical problems such as the loss of a certain amount of information
found in the original data. Considering the learning process as a framework of interacting roles and
factors, the discovery of patterns in that system can be really useful and beneficial firstly for the learners
and furthermore, the ability to publish and share these results would be very helpful for the whole
academic institution.
