Pure Language Technology (NLG)
Delivering a significant, customized expertise past pre-scripted responses requires pure language era. This allows the chatbot to interrogate information repositories, together with built-in back-end techniques and third-party databases, and to make use of that data in making a response.
Conversational AI know-how takes NLP and NLU to the subsequent degree. It permits enterprises to create superior dialogue techniques that make the most of reminiscence, private preferences and contextual understanding to ship a practical and interesting pure language interface.
