Natural Language Understanding NLU definition Conversational AI Dictionary
This process starts by identifying a document’s main topic and then leverages NLP to figure out how the document should be written in the user’s native language. By default, virtual assistants tell you the weather for your current location, unless you specify a particular city. The goal of question answering is to give the user response in their natural language, rather than a list of text answers. Text analysis solutions enable machines to automatically understand the content of customer support tickets and route them to the correct departments without employees having to open every single ticket. Not only does this save customer support teams hundreds of hours,it also helps them prioritize urgent tickets.
But, with NLU involved, it would understand that the sentence was a crude way of saying that James passed away. With Akkio’s intuitive interface and built-in training models, even beginners can create powerful AI solutions. Beyond NLU, Akkio is used for data science tasks like lead scoring, fraud detection, churn prediction, or even informing healthcare decisions. To demonstrate the power of Akkio’s easy AI platform, we’ll now provide a concrete example of how it can be used to build and deploy a natural language model.
Natural Language Understanding is also making things like Machine Translation possible. Machine Translation, also known as automated translation, is the process where a computer software performs language translation and translates text from one language to another without human involvement. Data capture is the process of extracting information from paper or electronic documents and converting it into data for key systems. Another challenge that NLU faces is syntax level ambiguity, where the meaning of a sentence could be dependent on the arrangement of words. In addition, referential ambiguity, which occurs when a word could refer to multiple entities, makes it difficult for NLU systems to understand the intended meaning of a sentence. Symbolic AI uses human-readable symbols that represent real-world entities or concepts.
A growing number of companies are finding that NLU solutions provide strong benefits for analyzing metadata such as customer feedback and product reviews. In such cases, NLU proves to be more effective and accurate than traditional methods, such as hand coding. NLU is a subset of a broader field called natural-language processing (NLP), which is already altering how we interact with technology. It can understand the context behind your users’ queries and empower your system to route them to the right agent the very first time. This kind of customer feedback can be extremely valuable to product teams, as it helps them to identify areas that need improvement and develop better products for their customers.
Sophisticated contract analysis software helps to provide insights which are extracted from contract data, so that the terms in all your contracts are more consistent. Natural language understanding (NLU) is already being used by thousands to millions of businesses as well as consumers. Experts predict that the NLP market will be worth more than $43b by 2025, which is a jump in 14 times its value from 2017.
Scope and context
Instead they are different parts of the same process of natural language elaboration. More precisely, it is a subset of the understanding and comprehension part of natural language processing. A Voice Assistant is an AI-infused software entity designed to interpret and respond to voice commands for users interact with through spoken language. A Large Language Model (LLM) is an advanced artificial intelligence system that processes and generates human language.
NLU systems are used on a daily basis for answering customer calls and routing them to the appropriate department. IVR systems allow you to handle customer queries and complaints on a 24/7 basis without having to hire extra staff or pay your current staff for any overtime hours. NLU is necessary in data capture since the data being captured needs to be processed and understood by an algorithm to produce the necessary results.
NLU examples and applications
NLU endeavors to fathom the nuances, the sentiments, the intents, and the many layers of meaning that our language holds. NLU-powered chatbots work in real time, answering queries immediately based on user intent and fundamental conversational elements. Techniques for NLU include the use of common syntax and grammatical rules to enable a computer to understand the meaning and context of natural human language.
Throughout the years various attempts at processing natural language or English-like sentences presented to computers have taken place at varying degrees of complexity. Some attempts have not resulted in systems with deep understanding, but have helped overall system usability. For example, Wayne Ratliff originally developed the Vulcan program with an English-like syntax to mimic the English speaking computer in Star Trek. There are 4.95 billion internet users globally, 4.62 billion social media users, and over two thirds of the world using mobile, and all of them will likely encounter and expect NLU-based responses. Consumers are accustomed to getting a sophisticated reply to their individual, unique input – 20% of Google searches are now done by voice, for example.
Data capture refers to the collection and recording data regarding a specific object, person, or event. If a company’s systems make use of natural language understanding, the system could understand a customers’ replies to questions and automatically enter the data. NLU goes beyond the sentence structure and aims to understand the intended meaning of language. While humans are able to effortlessly handle mispronunciations, swapped words, contractions, colloquialisms, and other quirks, machines are less adept at handling unpredictable inputs. Explore some of the latest NLP research at IBM or take a look at some of IBM’s product offerings, like Watson Natural Language Understanding.
So the system must first learn what it should say and then determine how it should say it. An NLU system can typically start with an arbitrary piece of text, but an NLG system begins with a well-controlled, detailed picture of the world. If you give an idea to an NLG system, the system synthesizes and transforms that idea into a sentence.
It involves the use of various techniques such as machine learning, deep learning, and statistical techniques to process written or spoken language. In this article, we will delve into the world of NLU, exploring its components, processes, and applications—as well as the benefits it offers for businesses and organizations. NLP is a field that deals with the interactions between computers and human languages.
Rather than using human resource to provide a tailored experience, NLU software can capture, process and react to the large quantities of unstructured data that customers provide at scale. 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. NLP is a broad field that encompasses a wide range of technologies and techniques, while NLU is a subset of NLP that focuses on a specific task. NLG, on the other hand, is a more specialized field that is focused on generating natural language output. Natural Language Understanding (NLU) can be considered the process of understanding and extracting meaning from human language.
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. 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.
- IVR makes a great impact on customer support teams that utilize phone systems as a channel since it can assist in mitigating support needs for agents.
- For example, if a customer says, “I want to order a pizza with extra cheese and pepperoni,” the AI chatbot uses NLP to understand that the customer wants to order a pizza and that the pizza should have extra cheese and pepperoni.
- These tickets can then be routed directly to the relevant agent and prioritized.
- Natural language generation is the process of turning computer-readable data into human-readable text.
- An NLU system can typically start with an arbitrary piece of text, but an NLG system begins with a well-controlled, detailed picture of the world.
In the realm of artificial intelligence, the ability for machines to grasp and generate human language is a domain rife with intrigue and challenges. To clarify, while ‘language processing’ might evoke images of text going through some form of computational mill, ‘understanding’ hints at a deeper level of comprehension. A subfield within artificial intelligence that concentrates on equipping machines with the capability to interpret, infer, and respond to human language inputs, often emphasizing semantics, context, and intent beyond mere syntax.
Biases in Language Models
NLP-enabled text mining has emerged as an effective and scalable solution for extracting biomedical entity relations from vast volumes of scientific literature. Tokenization is the process of breaking down a string of text into smaller units called tokens. For instance, a text document could be tokenized into sentences, phrases, words, subwords, and characters.
The terms Natural Language Processing (NLP), Natural Language Understanding (NLU), and Natural Language Generation (NLG) are often used interchangeably, but they have distinct differences. These three areas are related to language-based technologies, but they serve different purposes. In this blog post, we will explore the differences between NLP, NLU, and NLG, and how they are used in real-world applications.
NLU is a crucial part of ensuring these applications are accurate while extracting important business intelligence from customer interactions. In the near future, conversation intelligence powered by NLU will help shift the legacy contact centers to intelligence centers that deliver great customer experience. It’s likely that you already have enough data to train the algorithms
Google may be the most prolific producer of successful NLU applications. The reason why its search, machine translation and ad recommendation work so well is because Google has access to huge data sets. For the rest of us, current algorithms like word2vec require significantly less data to return useful results.

Understanding AI methodology is essential to ensuring excellent outcomes in any technology that works with human language. Hybrid natural language understanding platforms combine multiple approaches—machine learning, deep learning, LLMs and symbolic or knowledge-based AI. They improve the accuracy, scalability and performance of NLP, NLU and NLG technologies. Now that we understand the basics of NLP, NLU, and NLG, let’s take a closer look at the key components of each technology. These components are the building blocks that work together to enable chatbots to understand, interpret, and generate natural language data. By leveraging these technologies, chatbots can provide efficient and effective customer service and support, freeing up human agents to focus on more complex tasks.

For example, NLU can be used to create chatbots that can simulate human conversation. These chatbots can answer customer questions, provide customer support, or make recommendations. 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. With NLU, even the smallest language details humans understand can be applied to technology.
NLP, NLU, and NLG are all branches of AI that work together to enable computers to understand and interact with human language. They work together to create intelligent chatbots that can understand, interpret, and respond to natural language queries in a way that is both efficient and human-like. Over the past decade, how businesses sell or perform customer service has evolved dramatically due to changes in how customers interact with the business. This is forcing contact centers to explore new ways to use technology to ensure better customer experience, customer satisfaction, and retention. NLU allows computers to communicate with people in their own language, eliminating the need for a specialized computer language. It also helps in analyzing social media sentiment, enhancing customer service, and improving accessibility through voice-activated systems.
While NLP is concerned with the ability of computers to analyze, understand, and generate human language, NLU, on the other hand, is focused on the ability of computers to understand the meaning and context of human language. It’s easier to define such a branch of computer science as natural language understanding when opposing it to a better known-of and buzzwordy natural language processing. Both NLP and NLU are related but distinct fields within artificial intelligence that deal with the ability of computers to process and understand human language. The more the NLU system interacts with your customers, the more tailored its responses become, thus, offering a personalised and unique experience to each customer. However, true understanding of natural language is challenging due to the complexity and nuance of human communication.
Today, it is utilised in everything from chatbots to search engines, understanding user queries quickly and outputting answers based on the questions or queries those users type. The last place that may come to mind that utilizes NLU is in customer service AI assistants. Overall, incorporating NLU technology into customer experience management can greatly improve customer satisfaction, increase agent efficiency, and provide valuable insights for businesses to improve their products and services. Furthermore, different languages have different grammatical structures, which could also pose challenges for NLU systems to interpret the content of the sentence correctly. Other common features of human language like idioms, humor, sarcasm, and multiple meanings of words, all contribute to the difficulties faced by NLU systems. One of the major applications of NLU in AI is in the analysis of unstructured text.

For computers to get closer to having human-like intelligence and capabilities, they need to be able to understand the way we humans speak. Knowledge of that relationship and subsequent action helps to strengthen the model. Of course, Natural Language Understanding can only function well if the algorithms and machine learning that form its backbone have been adequately trained, with a significant database of information provided for it to refer to. Entity recognition identifies which distinct entities are present in the text or speech, helping the software to understand the key information. Named entities would be divided into categories, such as people’s names, business names and geographical locations.
This branch of AI lets analysts train computers to make sense of vast bodies of unstructured text by grouping them together instead of reading each one. That makes it possible to do things like content analysis, machine translation, topic modeling, and question answering on a scale that would be impossible for humans. The NLU field is dedicated to developing strategies and techniques for understanding context in individual records and at scale. NLU systems empower analysts to distill large volumes of unstructured text into coherent groups without reading them one by one.
- At the most sophisticated level, they should be able to hold a conversation about anything, which is true artificial intelligence.
- In general, when accuracy is important, stay away from cases that require deep analysis of varied language—this is an area still under development in the field of AI.
- LLM models can recognize, summarize, translate, predict and generate languages using very large text based dataset, with little or no training supervision.
Intent recognition involves identifying the purpose or goal behind an input language, such as the intention of a customer’s chat message. For instance, understanding whether a customer is looking for information, reporting an issue, or making a request. On the other hand, entity recognition involves identifying relevant pieces of information within a language, such as the names of people, organizations, locations, and numeric entities.
NLP, NLU, and NLG are different branches of AI, and they each have their own distinct functions. NLP involves processing large amounts of natural language data, while NLU is concerned with interpreting the meaning behind that data. NLG, on the other hand, involves using algorithms to generate human-like language in response to specific prompts.
These technologies work together to create intelligent chatbots that can handle various customer service tasks. As we see advancements in AI technology, we can expect chatbots to have more efficient and human-like interactions with customers. From the time we started, we have been using AI technologies like NLP, NLU & NLG to boost the contact center performance with live conversation intelligence. Our AI engine is able to uncover insights from 100% of customer interactions that maximizes frontline team performance through coaching and end-to-end workflow automation. With our AI technology, companies can act faster with real-time insights and guidance to improve performance, from more sales to higher retention. NLU or Natural Language Understanding is a subfield of Artificial Intelligence (AI) that focuses on the interaction between humans and computers using natural language.
Botpress can be used to build simple chatbots as well as complex conversational language understanding projects. The platform supports 12 languages natively, including English, French, Spanish, Japanese, and Arabic. Language capabilities can be enhanced with the FastText model, granting users access to 157 different languages. Natural language understanding software doesn’t just understand the meaning of the individual words within a sentence, it also understands what they mean when they are put together. You can foun additiona information about ai customer service and artificial intelligence and NLP. This means that NLU-powered conversational interfaces can grasp the meaning behind speech and determine the objectives of the words we use. You see, when you analyse data using NLU or natural language understanding software, you can find new, more practical, and more cost-effective ways to make business decisions – based on the data you just unlocked.
IVR, or Interactive Voice Response, is a technology that lets inbound callers use pre-recorded messaging and options as well as routing strategies to send calls to a live operator. Using symbolic AI, everything is visible, understandable what does nlu mean and explained within a transparent box that delivers complete insight into how the logic was derived. This transparency makes symbolic AI an appealing choice for those who want the flexibility to change the rules in their NLP model.
NLU is concerned with understanding the meaning and intent behind data, while NLG is focused on generating natural-sounding responses. 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.
NLU goes a step further by understanding the context and meaning behind the text data, allowing for more advanced applications such as chatbots or virtual assistants. For machines, human language, also referred to as natural language, is how humans communicate—most often in the form of text. It comprises the majority of enterprise data and includes everything from text contained in email, to PDFs and other document types, chatbot dialog, social media, etc. With the help of natural language understanding (NLU) and machine learning, computers can automatically analyze data in seconds, saving businesses countless hours and resources when analyzing troves of customer feedback. While NLU, NLP, and NLG are often used interchangeably, they are distinct technologies that serve different purposes in natural language communication.
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. Human language is typically difficult for computers to grasp, as it’s filled with complex, subtle and ever-changing meanings. Natural language understanding systems let organizations create products or tools that can both understand words and interpret their meaning.
