摘要：In this paper some results are presented which permit the graphic representation of the similarities between subjects which appear on web pages found on the Internet. To this end, these similarities are quantified and graphically represented by means of an index between the different subjects, in accordance with an intuitive interpretation of similarity between sets. The use of a function based on Learning Theory, enable us to study the similarity or interrelation between different lines of investigations corresponding to information on web pages. The visual analysis of the aforementioned interrelations has been applied to the area of Learning research refering to the period May 2003-May 2004. Furthermore, various tables which clarify the potential of this similarity index are constructed.
