Why NLP is a must for your chatbot

At its core, NLU is the capability of a machine to interpret, analyze, and understand human language in a manner that resembles human comprehension. Unlike traditional language processing, which deals with syntax and structure, NLU dives deeper, focusing on the semantics and intent behind the words and phrases. It probably requires much world knowledge – not only semantic and pragmatic knowledge, but also something like what the educational reformer E. We’ve seen that NLP primarily deals with analyzing the language’s structure and form, focusing on aspects like grammar, word formation, and punctuation.

With NLU, even the smallest language details humans understand can be applied to technology. Twilio Autopilot, the first fully programmable conversational application platform, includes a machine learning-powered NLU engine. It can be easily trained to understand the meaning of incoming communication in real-time and then trigger the appropriate actions or replies, connecting the dots between conversational input and specific tasks. Humans can communicate more effectively with systems that understand their language, and those machines can better respond to human needs. The most common example of natural language understanding is voice recognition technology. Voice recognition software can analyze spoken words and convert them into text or other data that the computer can process.

Unsupervised learning techniques such as clustering, dimensionality reduction, and anomaly detection are used to train NLU models. Ecommerce websites rely heavily on sentiment analysis of the reviews and feedback from the users—was a review positive, negative, or neutral? Here, they need to know what was said and they also need to understand what was meant. Going back to our weather enquiry example, it is NLU which enables the machine to understand that those three different questions have the same underlying weather forecast query. After all, different sentences can mean the same thing, and, vice versa, the same words can mean different things depending on how they are used.

The system is used for the follow-up of therapies in which data originate from various physicians and the patient itself. It allows one to answer (with possibility of undefined answers) to various questions about the the patient. In this system (like in many other) granularity usually means “converting units with alignment problems”. Meta-training supports a persona-independent framework for fast adaptation on minimal historical dialogues without persona descriptions. In addition, the meta-learner leverages knowledge from high-resource source domains then enables the adaptation of low-data target domains within a few steps of gradient updating.

NLU powered by neural networks helps determine the intent of an email by scanning language usage for topic and sentiment. Over the past year, 50 percent of major organizations have adopted artificial intelligence, according to a McKinsey survey. Beyond merely investing in AI and machine learning, leaders must know how to use these technologies to deliver value.
