This dataset represents the results of the experimentation of a method for evaluating semantic similarity between concepts in a taxonomy. The method is based on the information-theoretic approach and allows senses of concepts in a given context to be considered. Relevance of senses is calculated in terms of semantic relatedness with the compared concepts. In a previous work , the adopted semantic relatedness method was the one described in , while in this work we adopted the one described in . This results in an improvement of the method. The dataset is composed of two folders, which contain the results of the previous and the new experimentation, respectively. In particular, in each folder there is a set of files, each referring to one pair of the well-known Miller and Charles benchmark dataset  for assessing semantic similarity. For each pair of concepts, the same 28 pairs are all considered as possible different contexts. We applied our proposal by extending 7 methods for computing semantic similarity in a taxonomy, selected from the literature. The methods considered in the experiment are referred to as (R, W&P, L, J&C, P&S, A, A&M): REFERENCES  Miller G.A., Charles W.G. 1991. Contextual correlates of semantic similarity.
