Theresult of this process may be that documents not similarprior to the enhancement become similar (semanticallyon some abstraction level) after the enhancement.This is because the enhancement process may introducein the document footprint abstract concepts from theontology. Using the ontology we can enhance the foot-printsby adding concepts that are not present in theoriginal document.
