Webbsimilarities = cosineSimilarity (bag,queries) returns similarities between the documents encoded by the bag-of-words or bag-of-n-grams model bag and queries using tf-idf matrices derived from the word counts in bag. The score in similarities (i,j) represents the similarity between the i th document encoded by bag and queries (j). WebbSimilarity matrices are symmetrical with typically ones along diagonal, Distance matrices are symmetrical with zeros along diagonal, and Directed graph matrices are not symmetrical. Symmetrical matrices only store the upper triangle. The Adjacency class can also accommodate labels, but does not require them. prowin chats
