NLP: Twitter Sentiment Analysis
Create a pipeline to remove stop-words, punctuation, and perform tokenization
Understand the theory and intuition behind Naive Bayes classifiers
Train a Naive Bayes Classifier and assess its performance
In this hands-on project, we will train a Naive Bayes classifier to predict sentiment from thousands of Twitter tweets. This project could be practically used by any company with social media presence to automatically predict customer's sentiment (i.e.: whether their customers are happy or not). The process could be done automatically without having humans manually review thousands of tweets and customer reviews. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.

TOP REVIEWS FROM NLP: TWITTER SENTIMENT ANALYSIS
Overall nicely guided small project. The tutor explained it very well. Please make more such short courses. More concepts from Basic NLP can be covered.
Able to follow the lectures and learn about the basics of data processing for text mining. Expect more in-depth knowledge about sentiment analysis.
This guided project is a chance to learn a basic technical skill in data cleaning. I love the explanation for Naive Bayes algorithm.
