摘要：Nowadays, the delivery of learning services is accomplished in a diversity of ways and subordinated to the rules of a competitive market, in the context of a globalization expansion. Moreover, the Internet, the websites and related technologies sustain this unprecedented diversity.

In other words, we illustrate user requirements through a method of analyzing educational portal usability for higher education in economics. Using data mining methods, we also built a profile for the students and grouped them in specific clusters based on their preference for e-Learning (instead of traditional methods) for their studies - a very motivating approach which could help both institution and students
