Abstract

In this paper, the notion of information, focusing on its representation was dealt with. A representation that takes into account of its specificities, especially the non-quantifiable ones like semantics was designed. It seems that the most suitable and abstract model that can encompass this approach is the concept of topology. The reason was explained and the fundamental links that rely on information and topology were provided. Through this representation, some fundamental operations that treat information and situate the Hausdorff property and its role in this context were discussed. Among these operations, for instance, were sortability and track-ability. Finally, a criterion for extractability of information through the compactness property of the associated topological space was given.

Key words: Information, semantics, qualitative aspects, topology, heuristics.
