6. The method of claim 5 , wherein the sensitivity scores are computed based on: (i) the IDF score of the respective sensitive term in a corpus, wherein the sensitivity scores are increased upon determining the IDF score of the respective sensitive term exceeds the predefined frequency threshold, wherein the frequency threshold specifies a threshold number of occurrences of the respective sensitive term in the corpus, and (ii) whether the respective sensitive term is a low level node of the ontology.
