Sentiment analysis is a process that helps businesses understand customer needs and attitudes, but it's challenging for developers to implement accurately with existing APIs. However, Symbl.ai's Sentiment API offers flexibility, extensibility, and user-friendliness, making it suitable for real-time sentiment analysis over WebSockets. The API applies aspect-based sentiment analysis, which categorizes data by topic and identifies the sentiment attributed to each one. It's non-assumptive, non-invasive, fully extensible, and user-friendly, allowing developers to create actionable analytics on a user-by-user or call-by-call basis. With Symbl.ai's APIs, developers can integrate real-time transcription and capture sentiments in conversations, providing valuable insights for businesses and applications.
