Automated Student Feedback Analysis System Using Machine Learning
Student feedback plays a very important role in improving the quality of education provided by educational institutions. Universities and colleges collect feedback from students to evaluate teaching methods, course structure, and overall academic performance. However, analysing large volumes of feedback manually is time-consuming and inefficient.
This project introduces an Automated Student Feedback Analysis System that processes student feedback data in CSV format and performs sentiment analysis using Natural Language Processing (NLP) techniques. The system uses NLTK and the Naive Bayes algorithm to classify student feedback into three categories: Positive, Neutral, and Negative.
Project Overview
The Automated Feedback Analysis System is designed to analyse student feedback collected through forms. The system allows the user to upload feedback data in CSV format, after which the system processes the data using NLTK and performs sentiment classification using the Naive Bayes Machine Learning algorithm.
The system evaluates each feedback comment and determines whether it expresses positive, neutral, or negative sentiment. This helps institutions identify areas where improvement is needed and understand students’ learning experiences more effectively.
Automating the feedback analysis process makes it easier for educational institutions to handle large datasets and extract meaningful insights from student opinions.
