The Vector Space Model is a mathematical model used for representing text documents as vectors of terms. In this model, each document is represented as a vector in a multi-dimensional space, where each dimension corresponds to a unique word in the corpus. The value in each dimension represents the frequency (or weight) of that word in the document.
concordance(self, document)-> generates a term frequency dictionary (concordance) for a document. It return a dictionary where keys are words and values are their frequencies in the document.document="hello world hello"concordance=vector_compare.concordance(document) # Output: {'hello': 2, 'world': 1}
magnitude(self, concordance)-> calculates the magnitude of a document vector based on its concordance. It return a float value representing the magnitude.$$magnitude = \sqrt{\sum(count\ of\ words)^2}$$ concordance= {'hello': 2, 'world': 1} magnitude=vector_compare.magnitude(concordance) # Output: 2.236
relation(self, concordance1, concordance2)-> Computes the cosine similarity between two document vectors based on their concordances. It return a float value representing the cosine similarity between the two document vectors (ranging from 0 to 1).
