NLU works by processing large datasets of human language using Machine Learning (ML) models. These models are trained on relevant training data that help them learn to recognize patterns in human language. There are various ways that people can express themselves, and sometimes this can vary from person to person.

For example for our check_order_status intent, it would be frustrating to input all the days of the year, so you just use a built in date entity type. 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.

Customer service and support

This technique is cheaper and faster to build, and is flexible enough to be customised, but requires a large amount of human effort to maintain. Intent classification is the process of classifying the customer’s intent by analysing the language they use. From categorizing text, gathering news and archiving individual pieces of text to analyzing content, it’s all possible with NLU. Real-world examples of NLU include small tasks like issuing short commands based on text comprehension to some small degree like redirecting an email to the right receiver based on basic syntax and decently sized lexicon. For example, using NLG, a computer can automatically generate a news article based on a set of data gathered about a specific event or produce a sales letter about a particular product based on a series of product attributes. Gathering diverse datasets covering various domains and use cases can be time-consuming and resource-intensive.

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. 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.

Customers all around the world want to engage with brands in a bi-directional communication where they not only receive information but can also convey their wishes and requirements.

Today’s Natural Language Understanding (NLG), Natural Language Processing (NLP), and Natural Language Generation (NLG) technologies are implementations of various machine learning algorithms, but that wasn’t always the case. Early attempts at natural language processing were largely rule-based and aimed at the task of translating between two languages. Some common applications of NLP include sentiment analysis, machine translation, speech recognition, chatbots, and text summarization. NLP is used in industries such as healthcare, finance, e-commerce, and social media, among others. For example, in healthcare, NLP is used to extract medical information from patient records and clinical notes to improve patient care and research. Natural Language Understanding (NLU) is a subfield of natural language processing (NLP) that deals with computer comprehension of human language.

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. Denys spends his days trying to understand how machine learning will impact our daily lives—whether it’s building new models or diving into the latest generative AI tech.

One popular approach is to utilize a supervised learning algorithm, like Support Vector Machines (SVM) or Naive Bayes, for intent classification. The first step in building an effective Chat PG NLU model is collecting and preprocessing the data. For example, an NLU-powered chatbot can extract information about products, services, or locations from unstructured text.

NLU, a subset of AI, is an umbrella term that covers NLP and natural language generation (NLG). But don’t confuse them yet, it is correct that all three of them deal with human language, but each one is involved at different points in the process and for different reasons. SHRDLU could understand simple English sentences in a restricted world of children’s blocks to direct a robotic arm to move items. ATNs and their more general format called «generalized ATNs» continued to be used for a number of years.

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. After preprocessing, NLU models use various ML techniques to extract meaning from the text. One common approach is using intent recognition, which involves identifying the purpose or goal behind a given text.

For over two decades CMSWire, produced by Simpler Media Group, has been the world’s leading community of customer experience professionals. Spotify’s “Discover Weekly” playlist further exemplifies the effective use of NLU and NLP in personalization.

The rise of chatbots can be attributed to advancements in AI, particularly in the fields of natural language processing (NLP), natural language understanding (NLU), and natural language generation (NLG). These technologies allow chatbots to understand and respond to human language in an accurate and natural way. NLU, a subset of NLP, delves deeper into the comprehension aspect, focusing specifically on the machine’s ability to understand the intent and meaning behind the text. While NLP breaks down the language into manageable pieces for analysis, NLU interprets the nuances, ambiguities, and contextual cues of the language to grasp the full meaning of the text. It’s the difference between recognizing the words in a sentence and understanding the sentence’s sentiment, purpose, or request.

NLU thereby allows computer software and applications to be more accurate and useful in responding to written and spoken commands. It’s important for developers to consider the difference between NLP and NLU when designing conversational search functionality because it impacts the quality of interpretation of what users say and mean. Essentially, NLP processes what was said or entered, while NLU endeavors to understand what was meant. The intent of what people write or say can be distorted through misspelling, fractured sentences, and mispronunciation. NLU pushes through such errors to determine the user’s intent, even if their written or spoken language is flawed.

While NLU, NLP, and NLG are often used interchangeably, they are distinct technologies that serve different purposes in natural language communication. NLU is concerned with understanding the meaning and intent behind data, while NLG is focused on generating natural-sounding responses. The sophistication of NLU and NLP technologies also allows chatbots and virtual assistants to personalize interactions based on previous interactions or customer data. This personalization can range from addressing customers by name to providing recommendations based on past purchases or browsing behavior.
