Look inside

In this liveProject, you’ll clean and analyze data scraped from Reddit to determine customer opinions of your products within a set time period. You’ll utilize common natural language processing techniques such as stemming, tokenization, and latent dirichlet allocation (LDA) to discover patterns in people’s opinions, and then visualize your results and summarize your findings.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

book resources

When you start your liveProject, you get full access to the following books for 90 days.

prerequisites

This liveProject is for confident Python programmers interested in taking their first steps into data analysis for marketing. To begin this liveProject you will need to be familiar with the following:


TOOLS
  • Basic pandas
  • Basic seaborn
TECHNIQUES
  • Intermediate exploratory data analysis

you will learn

In this liveProject, you’ll explore text preprocessing and NLP analysis techniques.


  • Checking for and cleaning up null and duplicate data
  • Drilling into selective threads/replies
  • Engineer new columns using pandas to obtain summary statistics about the replies and threads
  • NLP preprocessing techniques such as stemming, n-gram, and removal of stop words using NLTK
  • Visualize word cloud and top n-grams
  • Perform topic modeling using LDA and visualize the topics
  • Summarize findings and use graphs to support your points
