It can also provide actionable data insights that lead to informed decision-making. Techniques commonly used in NLU include deep learning and statistical machine translation, which allows for more accurate and real-time analysis of text data. Overall, NLU technology is set to revolutionize the way businesses handle text data and provide a more personalized and efficient customer experience. Natural Language Understanding (NLU) has become an essential part of many industries, including customer service, healthcare, finance, and retail.

  • 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.
  • Though different to an extent their correlation is what is driving the change in various modern day industries.
  • There are thousands of ways to request something in a human language that still defies conventional natural language processing.

  • These pipelines are central to chatbots and other conversational agents for understanding user queries and generating appropriate responses.

Since the 1950s, the computer and language have been working together from obtaining simple input to complex texts. It was Alan Turing who performed the Turing test to know if machines are intelligent enough or not. Technology continues to advance and contribute to various domains, enhancing human-computer interaction and enabling machines to comprehend and process language inputs more effectively. This book is for managers, programmers, directors – and anyone else who wants to learn machine learning. Conversely, NLU focuses on extracting the context and intent, or in other words, what was meant. 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.

NLU Overview

In practical applications such as customer support, recommendation systems, or retail technology services, it’s crucial to seamlessly integrate these technologies for more accurate and context-aware responses. NLP utilizes statistical models and rule-enabled systems to handle and juggle with language. It often relies on linguistic rules and patterns to analyze and generate text. Handcrafted rules are designed by experts and specify how certain language elements should be treated, such as grammar rules or syntactic structures. Statistical approaches are data-driven and can handle more complex patterns.

NLU is no more an inflated concept, it is the present day technology that can redefine the entire future. It can modify the work cases in multiple industries, it can perform many operations in the shortest possible time span. Let’s take a look at the companies that are exploring the advantages of Natural Language Understanding. By analyzing any given piece can depict the emotions of the speaker.

Natural Language Understanding (NLU Tutorial)- Applications & Steps

Before a computer can process unstructured text into a machine-readable format, first machines need to understand the peculiarities of the human language. When a customer service ticket is generated, chatbots and other machines can interpret the basic nature of the customer’s need and rout them to the correct department. Companies receive thousands of requests for support every day, so NLU algorithms are useful in prioritizing tickets and enabling support agents to handle them in more efficient ways. In AI, two main branches play a vital role in enabling machines to understand human languages and perform the necessary functions. Pursuing the goal to create a chatbot that can hold a conversation with humans, researchers are developing chatbots that will be able to process natural language.

These notions are connected and often used interchangeably, but they stand for different aspects of language processing and understanding. Distinguishing between NLP and NLU is essential for researchers and developers to create appropriate AI solutions for business automation tasks. Natural Language Understanding and Natural Language Processes have one large difference.

Since then, with the help of progress made in the field of AI and specifically in NLP and NLU, we have come very far in this quest. In the world of AI, for a machine to be considered intelligent, it must pass the Turing Test. A test developed by Alan Turing in the 1950s, which pits humans against the machine. Models in NLP are usually sequential models, they process the queries and can modify each other.

Another difference is that NLP breaks and processes language, while NLU provides language comprehension. The first successful attempt came out in 1966 in the form of the famous ELIZA program which was capable of carrying on a limited form of conversation with a user. All these sentences have the same underlying question, which is to enquire about today’s weather forecast. In this context, another term which is often used as a synonym is Natural Language Understanding (NLU). Below, you’ll find a comprehensive list of NLU models available on Smartly.AI, along with their features and current status.

Natural language processing works by taking unstructured data and converting it into a structured data format. For example, the suffix -ed on a word, like called, indicates past tense, but it has the same base infinitive (to call) as the present tense verb calling. NLU goes beyond the basic processing of language and is meant to comprehend and extract meaning from text or speech. As a result, NLU  deals with more advanced tasks like semantic analysis, coreference resolution, and intent recognition. In today’s age of digital communication, computers have become a vital component of our lives. As a result, understanding human language, or Natural Language Understanding (NLU), has gained immense importance.

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. So, even though there are many overlaps between NLP and NLU, this differentiation sets them distinctly apart. A task called word sense disambiguation, which sits under the NLU umbrella, makes sure that the machine is able to understand the two different senses that the word “bank” is used. Given the rapid advancements in NLU technologies, we frequently release updated and improved pipelines featuring different algorithms and methodologies.

Based on some data or query, an NLG system would fill in the blank, like a game of Mad Libs. But over time, natural language generation systems have evolved with the application of hidden Markov chains, recurrent neural networks, and transformers, enabling more dynamic text generation in real time. It’s often used in conversational interfaces, such as chatbots, virtual assistants, and customer service platforms.

NLU is the ability of computers to understand human language, making it possible for machines to interact with humans in a more natural and intuitive way. For businesses, it’s important to know the sentiment of their users and customers overall, and the sentiment attached to specific themes, such as areas of customer service or specific product features. Accurately translating text or speech from one language to another is one of the toughest challenges of natural language processing and natural language understanding. With text analysis solutions like MonkeyLearn, machines can 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, but it also helps them prioritize urgent tickets. 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.

When are machines intelligent?

If accuracy is less important, or if you have access to people who can help where necessary, deepening the analysis or a broader field may work. 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. 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. AI technology has become fundamental in business, whether you realize it or not.

NLU derives the “actual meaning” from a given query, it further helps computers to develop an understanding of the human language. Natural language processing and its subsets have numerous practical applications within today’s world, like healthcare diagnoses or online customer service. In recent years, with so many advancements in research and technology, companies and industries worldwide have opted for the support of Artificial Intelligence (AI) to speed up and grow their business. AI uses the intelligence and capabilities of humans in software and programming to boost efficiency and productivity in business. 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.

Many NLP tasks, such as part-of-speech or text categorization, do not always require actual understanding in order to perform accurately, but in some cases they might, which leads to confusion between these two terms. As a rule of thumb, an algorithm that builds a model that understands meaning falls under natural language understanding, not just natural language processing. In a nutshell, Natural Language Understanding “a branch of artificial intelligence”, a “subset of natural language processing”,  can be used for real understanding of human language.
