The effective use of CMS requires that instructors can be provided with appropriate means of diagnosing problems. The aim of this research is to support the comprehension of the semantics content evolution within eLearning environments through uncovering by means of visual representations. Therefore, we have carried out the meaning of an eLearning database and represented the more relevant results by depicting them using a visualization based on the tag cloud visual representation. Additionally, we have validated our proposal through a case study.
