# Sentiment Analysis - Indodax



**Author:** Alessandro Javva Ananda Satriyo



This project focuses on performing sentiment analysis on data related to Indodax, the largest cryptocurrency exchange in Indonesia. The primary goal is to classify sentiments (positive, neutral, negative) from user reviews of the Indodax app, using various machine learning techniques.



## Project Overview



The notebook (`sentiment-analysis.ipynb`) contains several key sections:



1. **Data Extraction**: Data is extracted using the `google-play-scraper` library, focusing on user reviews from the Google Play Store. This section handles gathering relevant data for sentiment analysis.

2. **Data Preprocessing**: Includes steps such as text cleaning, tokenization, and encoding of sentiment labels to prepare the raw data for analysis.

3. **Feature Extraction**:

   - **TF-IDF**: Converts text data into numerical features for machine learning models.

   - **Bag of Words (BoW)**: Another method used for converting text data into features, particularly combined with the Simple RNN model.

4. **Model Training and Evaluation**: Implements and evaluates several machine learning models:

   - **LSTM** and **MLP** models using TF-IDF.

   - **Simple RNN** model using Bag of Words for feature extraction.

5. **Inference and Output**: Performs inference on test data and produces categorical sentiment labels (e.g., positive, neutral, negative).



## Indodax Overview



Indodax is the largest cryptocurrency exchange in Indonesia. It allows users to trade various digital assets such as Bitcoin, Ethereum, and others. The platform is known for its secure trading environment and is widely used by crypto enthusiasts and investors in Indonesia.
