Sentiment Analysis Tool

Project Overview

Build a powerful sentiment analysis tool that leverages machine learning to analyze text sentiment. This project combines NLP techniques with modern web technologies to create a practical AI application.

User Stories

  1. As a data analyst, I want to:

    • Analyze text sentiment in real-time
    • Process large batches of text data
    • Export analysis results in various formats
    • Track sentiment trends over time
  2. As a developer, I want to:

    • Access sentiment analysis via API
    • Customize the model parameters
    • Monitor model performance metrics
    • Handle multiple languages efficiently
  3. As a business user, I want to:

    • Upload documents for sentiment analysis
    • Generate comprehensive reports
    • Visualize sentiment distributions
    • Share analysis results with team members

Example Code

from transformers import pipeline
from flask import Flask, request, jsonify

app = Flask(__name__)
sentiment_analyzer = pipeline("sentiment-analysis")

@app.route('/analyze', methods=['POST'])
def analyze_sentiment():
    text = request.json.get('text')
    result = sentiment_analyzer(text)[0]

    return jsonify({
        'text': text,
        'sentiment': result['label'],
        'confidence': result['score']
    })

Learning Outcomes
