Recently we walked you through on how to train a sentiment analysis classifier for hotel reviews using Scrapy and MonkeyLearn. This tutorial is a perfect example on how we can combine web scraped data and machine learning for discovering valuable insights about a particular industry. With this model we were able to analyze millions of reviews and understand if guests love or hate different hotels. But besides understanding the sentiment of a review, wouldn't be interesting to understand what particular aspects do the guests love or hate about a particular hotel? This post will cover how you can create a machine learning classifier to understand the different aspects of hotel reviews.
