NLP, NLU, and NLG: Whats The Difference? A Comprehensive Guide

From deciphering speech to reading text, our brains work tirelessly to understand and make sense of the world around us. However, our ability to process information is limited to what we already know. Similarly, machine learning involves interpreting information to create knowledge. Understanding NLP is the first step toward exploring the frontiers of language-based AI and ML.

Common tasks include parsing, speech recognition, part-of-speech tagging, and information extraction. The terms NLP, NLU, and NLG are commonly used in the field of artificial intelligence, particularly when referring to the interaction between machines and human languages. While they may sometimes be used difference between nlp and nlu interchangeably by those unfamiliar with the field, each term denotes a distinct aspect of language processing. Let’s delve into these concepts to understand their differences, applications, and real-world examples. Similarly, NLU is expected to benefit from advances in deep learning and neural networks.

Sometimes people know what they are looking for but do not know the exact name of the good. In such cases, salespeople in the physical stores used to solve our problem and recommended us a suitable product. In the age of conversational commerce, such a task is done by sales chatbots that understand user intent and help customers to discover a suitable product for them via natural language (see Figure 6). The fascinating world of human communication is built on the intricate relationship between syntax and semantics. While syntax focuses on the rules governing language structure, semantics delves into the meaning behind words and sentences.

If you give an idea to an NLG system, the system synthesizes and transforms that idea into a sentence. It uses a combinatorial process of analytic output and contextualized outputs to complete these tasks. NLU is the ability of a machine to understand and process the meaning of speech or text presented in a natural language, that is, the capability to make sense of natural language. To interpret a text and understand its meaning, NLU must first learn its context, semantics, sentiment, intent, and syntax. Semantics and syntax are of utmost significance in helping check the grammar and meaning of a text, respectively. Though NLU understands unstructured data, part of its core function is to convert text into a structured data set that a machine can more easily consume.
