Youtube Comments Extraction and Sentiment Analysis Flask App – with source code – 2024

Hey guys in this blog we will implement Youtube Comments Extraction and Sentiment Analysis in Python using Flask. It is going to be a very interesting project. So without any further due, let’s do it…

YouTube is one of the most popular video-sharing platforms in the world, with over 2 billion monthly active users. As a result, it generates a massive amount of data in the form of comments, which can provide valuable insights into the user’s opinion about a particular video or topic. In this article, we will discuss a project on YouTube comments extraction and sentiment analysis using Python and Flask.

Technology Stack

  • Frontend – HTML and CSS
  • Backend – Flask(Python)

Working of our Youtube Comments Extraction and Sentiment Analysis App…

  • On the main page, we first enter/paste a youtube video url whose comments we need to analyze.
  • Then we click on the ‘Analyse Comments‘ button.
  • As soon as we hit the above button, our scrapper starts scraping comments from that video.
  • Now that we have a list of all the scraped comments, we will then clean these comments and run a sentiment analysis model on these cleaned comments.
  • A list of these cleaned comments along with their sentiment is sent on the results page.
  • All the POSITIVE sentiment comments have a green background, all NEGATIVE sentiment comments have a red background and all NEUTRAL comments have a gray background.
  • In the menu bar, we have a wordcloud option that will open up a wordcloud (as shown above) created accordingly from the scraped comments for a respective video.
