The basic idea, “Inverse Text Frequency” As an example, movie may occur often in case we talk about movie reviews (fun fact: we are about to analyze movie reviews) — however, the occurrence of ‘movie’ is not very likely to provide us with any solid information whether two text snippets may be similar. The NLTK library contains various utilities that allow you to effectively manipulate and analyze linguistic data. Let’s write a quick function to sort these extracted keyphrases and scores. Actually, No library is perfect. Just be sure to use the correct API . Mathematically, it measures the cosine of the angle between two vectors projected in a multi-dimensional space. Tokenization.
