Table 2 shows the INVR scores for our various techniques using the BNC with cut-offs of 5 and 100.
the angular similarity gives the cosine by the probability can be derived from the Hamming distance: By combining equations 5 and 6 we get the following approximation of the cosine distance: the cosine of two context vectors is approximated by the cosine of the Hamming distance between their two signatures normalised by the size of the signatures.
