NLU vs NLP: Unlocking the Secrets of Language Processing in AI

What Is Natural Language Understanding NLU ?

nlu nlp

This data helps virtual assistants and other applications determine a user’s intent and route them to the right task. Hence the breadth and depth of “understanding” aimed at by a system determine both the complexity of the system (and the implied challenges) and the types of applications it can deal with. The “breadth” of a system is measured by the sizes of its vocabulary and grammar.

Distinguishing between NLP and NLU is essential for researchers and developers to create appropriate AI solutions for business automation tasks. Automate data capture to improve lead qualification, support escalations, and find new business opportunities. For example, ask customers questions and capture their answers using Access Service Requests (ASRs) to fill out forms and qualify leads. With the availability of APIs like Twilio Autopilot, NLU is becoming more widely used for customer communication. This gives customers the choice to use their natural language to navigate menus and collect information, which is faster, easier, and creates a better experience.

Using data modelling to learn what we really mean

We don’t really think much of it every time we speak but human language is fluid, seamless, complex and full of nuances. What’s interesting is that two people may read a passage and have completely different interpretations based on their own understanding, values, philosophies, mindset, etc. NLG is a process whereby computer-readable data is turned into human-readable data, so it’s the opposite of NLP, in a way. Natural Language Understanding and Natural Language Processes have one large difference.

While both these technologies are useful to developers, NLU is a subset of NLP. This means that while all natural language understanding systems use natural language processing techniques, not every natural language processing system can be considered a natural language understanding one. This is because most models developed aren’t meant to answer semantic questions but rather predict user intent or classify documents into various categories (such as spam). Natural Language Processing is the process of analysing and understanding the human language. It’s a subset of artificial intelligence and has many applications, such as speech recognition, translation and sentiment analysis. Conversational interfaces, also known as chatbots, sit on the front end of a website in order for customers to interact with a business.

Machine Learning

These tools and platforms, while just a snapshot of the vast landscape, exemplify the accessible and democratized nature of NLU technologies today. By lowering barriers to entry, they’ve played a pivotal role in the widespread adoption and innovation in the world of language understanding. In essence, NLU, once a distant dream of the AI community, now influences myriad aspects of our digital interactions. From the movies we watch to the customer support we receive — it’s an invisible hand, guiding and enhancing our experiences. Deep learning’s impact on NLU has been monumental, bringing about capabilities previously thought to be decades away. However, as with any technology, it’s accompanied by its set of challenges that the research community continues to address.

  • These tickets can then be routed directly to the relevant agent and prioritized.
  • At its most basic, sentiment analysis can identify the tone behind natural language inputs such as social media posts.
  • That leaves three-quarters of the conversation for research–which is often manual and tedious.
  • For example, for HR specialists seeking to hire Node.js developers, the tech can help optimize the search process to narrow down the choice to candidates with appropriate skills and programming language knowledge.

Let’s take an example of how you could lower call center costs and improve customer satisfaction using NLU-based technology. Intent recognition identifies what the person speaking or writing intends to do. Identifying their objective helps the software to understand what the goal of the interaction is. In this example, the NLU technology is able to surmise that the person wants to purchase tickets, and the most likely mode of travel is by airplane. The search engine, using Natural Language Understanding, would likely respond by showing search results that offer flight ticket purchases. The voice assistant uses the framework of Natural Language Processing to understand what is being said, and it uses Natural Language Generation to respond in a human-like manner.

NLU is nothing but an understanding of the text given and classifying it into proper intents. You can type text or upload whole documents and receive translations in dozens of languages using machine translation tools. Google Translate even includes optical character recognition (OCR) software, which allows machines to extract text from images, read and translate it.

When information goes into a typical NLP system, it goes through various phases, including lexical analysis, discourse integration, pragmatic analysis, parsing, and semantic analysis. It encompasses methods for extracting meaning from text, identifying entities in the text, and extracting information from its structure.NLP enables machines to understand text or speech and generate relevant answers. It is also applied in text classification, document matching, machine translation, named entity recognition, search autocorrect and autocomplete, etc. NLP uses computational linguistics, computational neuroscience, and deep learning technologies to perform these functions. NLU processes linguistic input from the user and interprets it into structured data that can be used by computer applications. ”, NLU is able to recognize that the user is asking for a particular type of information and can then provide an appropriate response.

NLU and NLG are the subsets of NLP engine

NLU makes it possible to carry out a dialogue with a computer using a human-based language. This is useful for consumer products or device features, such as voice assistants and speech to text. Most of the time financial consultants try to understand what customers were looking for since customers do not use the technical lingo of investment.

NLU also enables computers to communicate back to humans in their own languages. Sentiment analysis and intent identification are not necessary to improve user experience if people tend to use more conventional sentences or expose a structure, such as multiple choice questions. This is in contrast to NLU, which applies grammar rules (among other techniques) to “understand” the meaning conveyed in the text. This is done by breaking down the text into smaller units, such as sentences or phrases.

Another area of advancement in NLP, NLU, and NLG is integrating these technologies with other emerging technologies, such as augmented and virtual reality. As these technologies continue to develop, we can expect to see more immersive and interactive experiences that are powered by natural language processing, understanding, and generation. 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. The callbot powered by artificial intelligence has an advanced understanding of natural language because of NLU.

  • Overall, natural language understanding is a complex field that continues to evolve with the help of machine learning and deep learning technologies.
  • For example, a restaurant receives a lot of customer feedback on its social media pages and email, relating to things such as the cleanliness of the facilities, the food quality, or the convenience of booking a table online.
  • Once computers learn AI-based natural language understanding, they can serve a variety of purposes, such as voice assistants, chatbots, and automated translation, to name a few.
  • Real-time agent assist applications dramatically improve the agent’s performance by keeping them on script to deliver a consistent experience.
  • NLP is a broad field that encompasses a wide range of technologies and techniques.
  • Though looking very similar and seemingly performing the same function, NLP and NLU serve different purposes within the field of human language processing and understanding.

For example, an NLG system might be used to generate product descriptions for an e-commerce website or to create personalized email marketing campaigns. Natural Language Processing(NLP) is a subset of Artificial intelligence which involves communication between a human and a machine using a natural language than a coded or byte language. It provides the ability to give instructions to machines in a more easy and efficient manner.

Extractive summarization is the AI innovation powering Key Point Analysis used in That’s Debatable. In this context, another term which is often used as a synonym is Natural Language Understanding (NLU).

However, NLU lets computers understand “emotions” and “real meanings” of the sentences. For those interested, here is our benchmarking on the top sentiment analysis tools in the market. This book is for managers, programmers, directors – and anyone else who wants to learn machine learning. To pass the test, a human evaluator will interact with a machine and another human at the same time, each in a different room. If the evaluator is not able to reliably tell the difference between the response generated by the machine and the other human, then the machine passes the test and is considered to be exhibiting “intelligent” behavior. NLP can process text from grammar, structure, typo, and point of view—but it will be NLU that will help the machine infer the intent behind the language text.

This is just one example of how natural language processing can be used to improve your business and save you money. The NLP market is predicted reach more than $43 billion in 2025, nearly 14 times more than it was in 2017. Millions of businesses already use NLU-based technology to analyze human input and gather actionable insights. Natural Language Understanding deconstructs human speech using trained algorithms until it forms a structured ontology, or a set of concepts and categories that have established relationships with one another. This computational linguistics data model is then applied to text or speech as in the example above, first identifying key parts of the language.
