BoW model for movie taglines
In this exercise, you have been provided with a corpus of more than 7000 movie tag lines. Your job is to generate the bag of words representation bow_matrix for these taglines. For this exercise, we will ignore the text preprocessing step and generate bow_matrix directly.
We will also investigate the shape of the resultant bow_matrix. The first five taglines in corpus have been printed to the console for you to examine.
