What is Natural Language Understanding NLU and how is it used in practice?

What is Natural Language Understanding NLU?

If you’ve ever wished that you could just talk to it and have it understand what you say, then you’re in luck. Thanks to natural language understanding, not only can computers understand the meaning of our words, but they can also use language to enhance our living and working conditions in new exciting ways. These are all good reasons for giving natural language understanding a go, but how do you know if the accuracy of an algorithm will be sufficient? Consider the type of analysis it will need to perform and the breadth of the field. Analysis ranges from shallow, such as word-based statistics that ignore word order, to deep, which implies the use of ontologies and parsing. Most other bots out there are nothing more than a natural language interface into an app that performs one specific task, such as shopping or meeting scheduling.

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. Check out this guide to learn about the 3 key pillars you need to get started. 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. Akkio offers a wide range of deployment options, including cloud and on-premise, allowing users to quickly deploy their model and start using it in their applications.

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. By combining linguistic rules, statistical models, and machine learning techniques, NLP enables machines to process, understand, and generate human language.

However, if a developer wants to build an intelligent contextual assistant capable of having sophisticated natural-sounding conversations with users, they would need NLU. NLU is the component that allows the contextual assistant to understand the intent of each utterance by a user. Without it, the assistant won’t be able to understand what a user means throughout a conversation.

The Transformative Power of Natural Language Processing (NLP)

Text analysis solutions enable machines to automatically understand 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. 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. 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.

This trove of information, often referred to as mobile traffic data, holds a wealth of insights about human behaviour within cities, offering a unique perspective on urban dynamics and patterns of movement. Imagine how much cost reduction can be had in the form of shorter calls and improved customer feedback as well as satisfaction levels. The goal of a chatbot is to minimize the amount of time people need to spend interacting with computers and maximize the amount of time they spend doing other things. Answering customer calls and directing them to the correct department or person is an everyday use case for NLUs. Implementing an IVR system allows businesses to handle customer queries 24/7 without hiring additional staff or paying for overtime hours. Ideally, your NLU solution should be able to create a highly developed interdependent network of data and responses, allowing insights to automatically trigger actions.

NLU is a form of data science that reads and analyzes the information gleaned from natural language processing. Additionally, it relies upon specific algorithms to help computers distinguish the intent of spoken or written language. NLU is also helps computers distinguish between and sort specific “entities,” which function somewhat like categories. NLU uses natural language processing (NLP) to analyze and interpret human language. NLP is a set of algorithms and techniques used to make sense of natural language.

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. If we were to explain it in layman’s terms or a rather basic way, NLU is where a natural language input is taken, such as a sentence or paragraph, and then processed to produce an intelligent output. NLU leverages machine learning algorithms to train models on labeled datasets.

Your software can take a statistical sample of recorded calls and perform speech recognition after transcribing the calls to text using machine translation. The NLU-based text analysis can link specific speech patterns to negative emotions and high effort levels. Using predictive modeling algorithms, you can identify these speech patterns automatically in forthcoming calls and recommend a response from your customer service representatives as they are on the call to the customer. This reduces the cost to serve with shorter calls, and improves customer feedback. NLU is widely used in virtual assistants, chatbots, and customer support systems.

• If you’re building a bank app, distinguishing between credit card and debit cards may be more important than types of pies.
• For example, entity analysis can identify specific entities mentioned by customers, such as product names or locations, to gain insights into what aspects of the company are most discussed.
• But when you use an integrated system that ‘listens,’ it can share what it learns automatically- making your job much easier.
• Suppose that a shopper queries “Show me classy black dresses for under $500.”  This query defines the product (dress), product type (black), price point (less than $500), and personal tastes and preferences (classy).

These typically require more setup and are typically undertaken by larger development or data science teams. For example, an NLU might be trained on billions of English phrases ranging from the weather to cooking recipes and everything in between. If you’re building a bank app, distinguishing between credit card and debit cards may be more important than types of pies.

Unlocking success: Key components of a winning customer experience strategy

So, if you’re Google, you’re using natural language processing to break down human language and better understand the true meaning behind a search query or sentence in an email. You’re also using it to analyze blog posts to match content to known search queries. The models examine context, previous messages, and user intent to provide logical, contextually relevant replies. It also facilitates sentiment analysis, which involves determining the sentiment or emotion expressed in a piece of text, and information retrieval, where machines retrieve relevant information based on user queries. NLP has the potential to revolutionize industries such as healthcare, customer service, information retrieval, and language education, among others.

A data capture application will enable users to enter information into fields on a web form using natural language pattern matching rather than typing out every area manually with their keyboard. It makes it much quicker for users since they don’t need to remember what each field means or how they should fill it out correctly with their keyboard (e.g., date format). Natural language understanding is the process of identifying the meaning of a text, and it’s becoming more and more critical in business. Natural language understanding software can help you gain a competitive advantage by providing insights into your data that you never had access to before.

Understanding cities through foot traffic data

Tokenization, part-of-speech tagging, syntactic parsing, machine translation, etc. Natural Language Processing (NLP) relies on semantic analysis to decipher text. To explore the exciting possibilities of AI and Machine Learning based on language, it’s important to grasp the basics of Natural Language Processing (NLP). It’s like taking the first step into a whole new world of language-based technology.

Common NLP tasks include tokenization, part-of-speech tagging, lemmatization, and stemming. NLG can be used to generate natural language summaries of data or to generate natural language instructions for a task such as how to set up a printer. The difference between natural language understanding and natural language generation is that the former deals with a computer’s ability to read comprehension, while the latter pertains to a machine’s writing capability.

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. Being able to rapidly process unstructured data gives you the ability to respond in an agile, customer-first way. Make sure your NLU solution is able to parse, process and develop insights at scale and at speed. A sophisticated NLU solution should be able to rely on a comprehensive bank of data and analysis to help it recognize entities and the relationships between them.
