Overview
Tokopedia Review Sentiment Analysis is a text analysis project focused on processing user reviews to identify positive, negative, or neutral sentiment toward a product. The project aims to help understand user perceptions in a more structured way through a Natural Language Processing and sentiment classification approach. By processing available review data, the system transforms textual opinions into information that is easier to analyze for product evaluation, market research, and decision-making purposes.
Problem Background
- User Reviews Are Difficult to Manage Manually: A large number of reviews makes it inefficient to read and understand user opinions manually.
- User Opinions Are Diverse and Unstructured: User reviews are written in different styles, making them difficult to analyze without an automated approach.
- Sentiment Information Is Not Immediately Actionable: Raw review data does not clearly help decision-makers unless it is transformed into structured sentiment information.
Solution Approach
- Automated Sentiment Analysis: Applies a classification model to identify user sentiment from review text automatically.
- Structured Text Processing: Performs text cleaning and preparation so reviews can be analyzed more accurately.
- Easier-to-Understand Information: Transforms user opinions into structured analytical results that are easier to use for product evaluation.
- Decision-Making Support: Provides sentiment analysis results that help interpret user responses toward products or services.
