What is Natural Language Understanding NLU?
AI technology has become fundamental in business, whether you realize it or not. Recommendations on Spotify or Netflix, auto-correct and auto-reply, virtual assistants, and automatic email categorization, to name just a few. 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.
- NLU-driven searches using tools such as Algolia Understand break down the important pieces of such requests to grasp exactly what the customer wants.
- Using a natural language understanding software will allow you to see patterns in your customer’s behavior and better decide what products to offer them in the future.
- With today’s mountains of unstructured data generated daily, it is essential to utilize NLU-enabled technology.
- Natural language understanding is critical because it allows machines to interact with humans in a way that feels natural.
- You can’t afford to force your customers to hop across dozens of agents before they finally reach the one that can answer their question.
It plays an important role in customer service and virtual assistants, allowing computers to understand text in the same way humans do. Similarly, NLU is expected to benefit from advances in deep learning and neural networks. We can expect to see virtual assistants and chatbots that can better understand natural language and provide more accurate and personalized responses.

As a result, customer service teams and marketing departments can be more strategic in addressing issues and executing campaigns. Natural language generation (NLG) is a process within natural language processing that deals with creating text from data. NLU plays a crucial role in dialogue management systems, where it understands and interprets user input, allowing the system to generate appropriate responses or take relevant actions. NLU goes beyond literal interpretation and involves understanding implicit information and drawing inferences.
questions to ask for relevant search results
If the latest “intent” is to add to the existing entities with updated information, DST also does that. From categorizing text, gathering news and archiving individual pieces of text to analyzing content, it’s all possible with NLU. While NLP and NLU are not interchangeable terms, they both work toward the end goal of understanding language.
By working together, NLP and NLU enhance each other’s capabilities, leading to more advanced and comprehensive language-based solutions. NLP models can determine text sentiment—positive, negative, or neutral—using several methods. This analysis helps analyze public opinion, client feedback, social media sentiments, and other textual communication. Understanding semantics requires context, inference, and word relationships. Complex languages with compound words or agglutinative structures benefit from tokenization. By splitting text into smaller parts, following processing steps can treat each token separately, collecting valuable information and patterns.
According to various industry estimates only about 20% of data collected is structured data. The remaining 80% is unstructured data—the majority of which is unstructured text data that’s unusable for traditional methods. Just think of all the online text you consume daily, social media, news, research, product websites, and more. Gone are the days when chatbots could only produce programmed and rule-based interactions with their users. Back then, the moment a user strayed from the set format, the chatbot either made the user start over or made the user wait while they find a human to take over the conversation.
NLU will play a key role in extracting business intelligence from raw data. In the future, communication technology will be largely shaped by NLU technologies; NLU will help many legacy companies shift from data-driven platforms to intelligence-driven entities. NLU provides support by understanding customer requests and quickly routing them to the appropriate team member. Because NLU grasps the interpretation and implications of various customer requests, it’s a precious tool for departments such as customer service or IT. It has the potential to not only shorten support cycles but make them more accurate by being able to recommend solutions or identify pressing priorities for department teams. If humans find it challenging to develop perfectly aligned interpretations of human language because of these congenital linguistic challenges, machines will similarly have trouble dealing with such unstructured data.
Natural language understanding (NLU) is a technical concept within the larger topic of natural language processing. NLU is the process responsible for translating natural, human words into a format that a computer can interpret. Essentially, before a computer can process language data, it must understand the data. Natural language processing is used when we want machines to interpret human language.
Let’s say, you’re an online retailer who has data on what your audience typically buys and when they buy. At times, NLU is used in conjunction with NLP, ML (machine learning) and NLG to produce some very powerful, customised solutions for businesses. It can be used to help customers better understand the products and services that they’re interested in, or it can be used to help businesses better understand their customers’ needs. Using a natural language understanding software will allow you to see patterns in your customer’s behavior and better decide what products to offer them in the future. NLP attempts to analyze and understand the text of a given document, and NLU makes it possible to carry out a dialogue with a computer using natural language.
Supervised models based on grammar rules are typically used to carry out NER tasks. In the early days of Artificial Intelligence (AI), researchers focused on creating machines that could perform specific tasks, such as playing chess or proving theorems. However, in recent years, there has been a shift to a “broad” focus, which is aimed at creating machines that can reason like humans. Chatbots are powered by NLU algorithms that understand the user’s intent and respond accordingly. Ecommerce websites rely heavily on sentiment analysis of the reviews and feedback from the users—was a review positive, negative, or neutral?
It involves tasks like entity recognition, intent recognition, and context management. ” the chatbot uses NLU to understand that the customer is asking about the business hours of the company and provide a relevant response. NLP involves the processing of large amounts of natural language data, including tasks like tokenization, part-of-speech tagging, and syntactic parsing.

NLU is branch of natural language processing (NLP), which helps computers understand and interpret human language by breaking down the elemental pieces of speech. While speech recognition captures spoken language in real-time, transcribes it, and returns text, NLU goes beyond recognition to determine a user’s intent. Speech recognition is powered by statistical machine learning methods which add numeric structure to large datasets.
It works by analyzing the meaning of a sentence, rather than simply its words, to determine how to respond. NLU starts by breaking down the sentence into components, such as the subject, verb, and object, and then uses NLP techniques to further analyze the words and determine the intent. The technology then uses this information to generate a response that is tailored to the user’s request.
Natural language understanding is a field that involves the application of artificial intelligence techniques to understand human languages. Natural language understanding aims to achieve human-like communication with computers by creating a digital system that can recognize and respond appropriately to human speech. Natural language understanding is taking a natural language input, like a sentence or paragraph, and processing it to produce an output. It’s often used in consumer-facing applications like web search engines and chatbots, where users interact with the application using plain language.
This meaning could be in the form of intent, named entities, or other aspects of human language. This includes understanding the meaning of words and sentences, as well as the intent behind them. These algorithms are backed by large libraries of information, which help them to more accurately understand human language. 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.
NLP enables computers and other software programs to interpret and understand human language to complete specific tasks. In order to respond appropriately to human language and commands, however, a computer must also use a form of data science known as natural language understanding. By looking at the ins and outs of natural language understanding (NLU), it’s possible to gain a clearer picture of the role it plays in natural language processing and artificial intelligence. On the other hand, NLU delves deeper into the semantic understanding and contextual interpretation of language.
Check out this guide to learn about the 3 key pillars you need to get started. One of the significant challenges that NLU systems face is lexical ambiguity. For instance, the word “bank” could mean a financial institution or the side of a river. If you’re starting from scratch, we recommend Spokestack’s NLU training data format.
