Professional Capability Objective
This capstone helps aspiring NLP engineers, junior data scientists, and machine learning professionals develop practical skills in sentiment analysis and text classification. You will preprocess movie-review data, transform text into numerical features using Bag-of-Words or TF-IDF, train and tune a classification model, and evaluate its performance using standard metrics. By the end, you will have a portfolio-ready project demonstrating hands-on proficiency in Python, NLP libraries, scikit-learn, and end-to-end machine learning development.
Industry Challenge
Organizations increasingly rely on customer reviews to understand audience opinions and improve their products and services. However, manually analyzing large volumes of unstructured text is time-consuming, inconsistent, and difficult to scale. Sentiment analysis offers an efficient way to automatically classify movie reviews as positive or negative using natural language processing and machine learning.
How can you build an accurate sentiment-analysis model that automatically classifies movie reviews as positive or negative?
Your analysis must consider:
- ▶Movie Review Dataset Acquisition and Preparation
- ▶Text Preprocessing and Normalization
- ▶Text Vectorization Using Bag-of-Words or TF-IDF
- ▶Classification Model Selection and Training
- ▶Hyperparameter Tuning
- ▶Performance Evaluation and Model Generalization
Why Employers Value This
