Tired of seeing this, you and a group of friends decide to create an extension for your favorite web browser that automatically hides negative comments when you visit Reddit. As a first step to tackle this NLP problem, one of your team members decides to build a machine learning model to classify comments. She implements a method called get_text_negative_proba that receives a string containing the comment to be analyzed and outputs a number between 0 and 1. The closer the number is to 1, the more likely it is to be a negative comment. She also implemented two other methods: get_text_neutral_proba and get_text_positive_proba that do the same thing as get_text_negative_proba, but for neutral and positive sentiments.
She also writes the code to communicate with Reddit programmatically using their API. She writes a method called get_submission_comments that receives the URL of a Reddit submission as input (check the source code to see an example) and returns all the submissions replies.
She asks you if you can implement the process_comments method she left blank. The purpose of this method is to traverse the replies tree of a given submission,and return three lists: negative_comments_list, neutral_comments_list and positive_comments_list . In other words, you need to traverse all of the replies in the submission, which are structured in a tree-like format.(Recursion)
When you call get_submission_comments, you get the submissions top replies (as a list). Each of these replies might have its own replies. To access a reply replies, you can type
This involves using Anaconda(Python 3.6), NLTK, and PRAW. Using Reddits API
