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']
})
