Machine learning and Lexicon based approach to Sentiment analysis using Twitter API


What you'll learn

How to create twitter developer account and connect to twitter API
Download Tweets, clean and store them in to Pandas DataFrame
Learn about Tokenization, Lemmatization, Stemming and much more
Perform Sentiment analysis with Vader and TextBlob lexicons
Learn about Machine learning approach to Sentiment Analysis
Build and test machine learning models

Requirements

Basic Python knowledge (I explain each step so you can understand what I am doing)

Description

Learn how to connect and download tweets through Twitter API. From there I will show you how to clean this data and prepare them for sentiment analysis. There are two most commonly used approaches to sentiment analysis so we will look at both of them. First one is Lexicon based approach where you can use prepared lexicons to analyse data and get sentiment of given text. Second one is Machine learning approach where we train our own model on labeled data and then we show it new data and hopefully our model will show us sentiment. At the end you will be able to build your own script to analyze sentiment of hundreds or even thousands of tweets about topic you choose.

Who this course is for:

Beginner Python developers curious about data science
Anyone who is interested in data analysis
People who wants to include sentiment analysis for their projects
