DatumBox provides a machine learning platform that specializes in natural language processing. The DatumBox API enables developers to integrate various DatumBox tools into third party applications, websites, or software. Through the API, developers can add any of the DatumBox features (e.g. text analysis, sentiment analysis, Twitter analysis, spam detection, and more).
