Every zip file contains two files: “lsaModel” and “voc”. Every line in the “voc” file is an individual word, while each line in the “lsaModel” file is a 300-dimensional vector in the latent space. There is a perfect correspondence between the lines of the two files and so, the vector on the i-th line in the “lsaModel” file is corresponding to the word on the i-th line in the “voc” file. The similarity between two words is usually computed as the cosine similarity between their corresponding vectors.
