Yelp Review Rating / Sentiment Modeling

TF-IDF + logistic regression

What this proves

  • Problem: needed to turn large volumes of review text into structured signals for customer sentiment and service issues.
  • Method: applied text preprocessing, TF-IDF vectorization, VADER and FLAIR sentiment labeling, and logistic regression classification.
  • Outcome: created a usable sentiment workflow that turns review language into repeatable service-improvement signals.

Live proof surface

This project currently has a recorded walkthrough plus downloadable project materials. It is a strong NLP and classification proof surface, but the public story stays focused on business-readable output rather than overstated model hype.
