16. An apparatus for automatic provision of an overall semantic similarity score value among a plurality of named entities comprising: a first calculation device calculating, for each pair in at least a selection of pairs of the named entities, a pair semantic similarity score value according to a classifier using an electronic information source; a second calculation device calculating, for each of the pairs in the selection of pairs of the named entities, a further pair semantic similarity score value according to a further classifier using the electronic information source; and a third calculation device calculating, for each of the pairs in the selection of the named entities an overall semantic similarity score value as a first function of the pair semantic similarity score value and the further pair semantic similarity score value corresponding thereto.
22. The apparatus according to claim 16 , wherein said first calculation device calculates the pair semantic similarity score value for each pair of the named entities.
