WebWeighted cosine similarity measure: iteratively computes the cosine distance between two documents, but at each iteration the vocabulary is defined by n-grams of different lengths. The weighted similarity measure gives a single similarity score, but is built from the cosine similarity between two documents taken at several levels of coarseness. Cosine similarity is a metric used to determine how similar the documents are irrespective of their size.
