Sentiment Analysis API

TheySay’s real-time Sentiment Analysis API gives you access to a state-of-the-art sentiment analysis algorithm through a scalable and secure RESTful API service.

Our analysis is powered by a hybrid Natural Language Processing (NLP) engine that runs highly sophisticated linguistic algorithms and Machine Learning classifiers. The engine is wrapped in a platform-agnostic REST API service that enables your software applications, workflows, and services to receive rich TheySay JSON metadata with minimal integration work.

Our API service is called PreCeive and is available for a 30-day free trial.
