What is Natural Language Understanding & How Does it Work?
What Is Natural Language Understanding NLU?
NLU, a subset of natural language processing (NLP) and conversational AI, helps conversational AI applications to determine the purpose of the user and direct them to the relevant solutions. While both understand human language, NLU communicates with untrained individuals to learn and understand their intent. In addition to understanding words and interpreting meaning, NLU is programmed to understand meaning, despite common human errors, such as mispronunciations or transposed letters and words.
In NLU systems, this output is often generated by computer-generated speech or chat interfaces, which mimic human language patterns and demonstrate the system’s ability to process natural language input. NLU also enables the development of conversational agents and virtual assistants, which rely on natural language input to carry out simple tasks, answer common questions, and provide assistance to customers. Another important application of NLU is in driving intelligent actions through understanding natural language. This involves interpreting customer intent and automating common tasks, such as directing customers to the correct departments. This not only saves time and effort but also improves the overall customer experience. One of the major applications of NLU in AI is in the analysis of unstructured text.

You’re also utilising the constantly evolving and improving models as those engineers learn from millions of customer interactions. Millions of people speaking to Alexa, Google Assistant and Lex/DialogFlow-powered chat and voicebots every day is all feeding into and improving the NLU’s ability to understand what people are saying. Once you have your intents, entities and sample utterances, you have what’s known as a language model.
Customer support agents can leverage NLU technology to gather information from customers while they’re on the phone without having to type out each question individually. Simply put, using previously gathered and analyzed information, computer programs are able to generate conclusions. For example, in medicine, machines can infer a diagnosis based on previous diagnoses using IF-THEN deduction rules.

The process of Natural Language Understanding (NLU) involves several stages, each of which is designed to dissect and interpret the complexities of human language. ATNs and their more general format called “generalized ATNs” continued to be used for a number of years. Generally, computer-generated content lacks the fluidity, emotion and personality that makes human-generated content interesting and engaging. However, NLG can be used with NLP to produce humanlike text in a way that emulates a human writer. This is done by identifying the main topic of a document and then using NLP to determine the most appropriate way to write the document in the user’s native language. In this case, the person’s objective is to purchase tickets, and the ferry is the most likely form of travel as the campground is on an island.
The “depth” is measured by the degree to which its understanding approximates that of a fluent native speaker. At the narrowest and shallowest, English-like command interpreters require minimal complexity, but have a small range of applications. Narrow but deep systems explore and model mechanisms of understanding,[25] but they still have limited application. Systems that are both very broad and very deep are beyond the current state of the art. NLG systems enable computers to automatically generate natural language text, mimicking the way humans naturally communicate — a departure from traditional computer-generated text. A naive NLU system takes a person’s speech or text as input, and tries to find the correct intent in its database.
NLU Techniques and Approaches
It also determines the relationship between different words, allowing it to understand the overall meaning of the sentence or text. When given a natural language input, NLU splits that input into individual words — called tokens — which include punctuation and other symbols. The tokens are run through a dictionary that can identify a word and its part of speech. The tokens are then analyzed for their grammatical structure, including the word’s role and different possible ambiguities in meaning. Knowing the rules and structure of the language, understanding the text without ambiguity are some of the challenges faced by NLU systems. NLG does exactly the opposite; given the data, it analyzes it and generates narratives in conversational language a human can understand.
While natural language understanding focuses on computer reading comprehension, natural language generation enables computers to write. NLG is the process of producing a human language text response based on some data input. This text can also be converted into a speech format through text-to-speech services. NLP refers to the broader field encompassing all aspects of language processing, including understanding and generation. NLP focuses on developing algorithms and techniques to enable computers to interact with and understand human language.
What are the steps in natural language understanding?
NLU enables these assistants to interpret natural language commands and respond with relevant information or actions. These NLU techniques and approaches have played a vital role in advancing the field and improving the accuracy and effectiveness of machine language understanding. Ongoing research and developments continue to push the boundaries of NLU, leading to more sophisticated and robust models for understanding and interpreting human language. The final stage is pragmatic analysis, which involves understanding the intention behind the language based on the context in which it’s used.
When you ask a digital assistant a question, NLU is used to help the machines understand the questions, selecting the most appropriate answers based on features like recognized entities and the context of previous statements. Whether you’re on your computer all day or visiting a company page seeking support via a chatbot, it’s likely you’ve interacted with a form of natural language understanding. When it comes to customer support, companies utilize NLU in artificially intelligent chatbots and assistants, so that they can triage customer tickets as well as understand customer feedback. Forethought’s own customer support AI uses NLU as part of its comprehension process before categorizing tickets, as well as suggesting answers to customer concerns.

Natural Language Understanding (NLU) is a field of computer science which analyzes what human language means, rather than simply what individual words say. Have you ever talked to a virtual assistant like Siri or Alexa and marveled at how they seem to understand what you’re saying? Or have you used a chatbot to book a flight or order food and been amazed at how the machine knows precisely what you want? These experiences rely on a technology called Natural Language Understanding, or NLU for short.
Natural Language Generation is the production of human language content through software. NLU works by processing large datasets of human language using Machine Learning (ML) models. These models are trained on relevant training data that help them learn to recognize patterns in human language. Voice assistants and virtual assistants have several common features, such as the ability to set reminders, play music, and provide news and weather updates.
Without NLU, Siri would match your words to pre-programmed responses and might give directions to a coffee shop that’s no longer in business. But with NLU, Siri can understand the intent behind your words and use that understanding to provide a relevant and accurate response. This article will delve deeper into how this technology works and explore some of its exciting possibilities.
Addressing lexical, syntax, and referential ambiguities, and understanding the unique features of different languages, are necessary for efficient NLU systems. Natural language processing is the process of turning human-readable text into computer-readable data. It’s used in everything from online search engines to chatbots that can understand our questions and give us answers based on what we’ve typed. For computers to get closer to having human-like intelligence and capabilities, they need to be able to understand the way we humans speak. Before a computer can process unstructured text into a machine-readable format, first machines need to understand the peculiarities of the human language.
This reduces the cost to serve with shorter calls, and improves customer feedback. With the rise of chatbots, virtual assistants, and voice assistants, the need for machines to understand natural language has become more crucial. In this article, we’ll delve deeper into what is natural language understanding and explore some of its exciting possibilities.
