Expert answer:Use python to compute the term-frequency matrix fo

Uncategorized

Answer & Explanation:A term frequency matrix is a table, where rows represent documents and columns represent the terms/words. The value in cell (i,j) is the number of times that word j occurs in document i.To do this, your python program first needs to go through the files in the input folder, where each file is a separate document (thus, the number of documents in the number of files), and build a set of all unique terms across all the documents.Let’s call this list of terms T, which contains n terms.Then you’ll need to go through each file/document, and compute the number of times that each of the n words occurs in that document. Doing this, you will produce the term-document matrix.The program should save this matrix in a file, where each row of the matrix appears on a separate line, and all terms occurrence frequencies are separated by commas.The folder with the documents, representing movie reviews, is included in the assignment. This is NOT a group project. I will fail automatically any submission which looks like another’s.reviews.zip
