cos_sim_calc
calculates the cosine measure of similarity between pairs of terms from a corpus.
cos_sim_calc(nummatrix)
nummatrix |
A numerical matrix for e.g. a Term Document matrix (output from tdm_for_lsa) |
The term document matrix is taken as input and cosine meausures of similarity between all pairs of terms are calculated.
A tab delimited text file containing the similarity values between all pairs of terms.
This file can be input to cytoscape directly.
