Natural language understanding (NLU) is a subfield of natural language processing (NLP), which involves transforming human language into a machine-readable format. 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. These approaches are also commonly used in data mining to understand consumer attitudes. In particular, sentiment analysis enables brands to monitor their customer feedback more closely, allowing them to cluster positive and negative social media comments and track net promoter scores. By reviewing comments with negative sentiment, companies are able to identify and address potential problem areas within their products or services more quickly.
Though natural language processing tasks are closely intertwined, they can be subdivided into categories for convenience. Neural machine translation, based on then-newly-invented sequence-to-sequence transformations, made obsolete the intermediate steps, such as word alignment, previously necessary for statistical machine translation. Natural Language Understanding is a vital part of the NLP process, which allows a conversational AI platform to extract intent from human input and formulate a response, whether from a scripted range or an AI-driven process. Using a set of linguistic guidelines coded into the platform that use human grammatical structures. However, this approach requires the formulation of rules by a skilled linguist and must be kept up-to-date as issues are uncovered.
NLU and NLG are the subsets of NLP engine
A basic form of NLU is called parsing, which takes written text and converts it into a structured format for computers to understand. Instead of relying on computer language syntax, NLU enables a computer to comprehend and respond to human-written text. Question answering is a subfield of NLP and speech recognition that uses NLU to help computers automatically understand natural language questions. 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.
NLU helps computers comprehend the meaning of words, phrases, and the context in which they are used. 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. Overall, natural language understanding is a complex field that continues to evolve with the help of machine learning and deep learning technologies.
NLU & The Future of Language
When he’s not leading courses on LLMs or expanding Voiceflow’s data science and ML capabilities, you can find him enjoying the outdoors on bike or on foot. 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. Its text analytics service offers insight into categories, concepts, entities, keywords, relationships, sentiment, and syntax from your textual data to help you respond to user needs quickly and efficiently. Help your business get on the right track to analyze and infuse your data at scale for AI. Natural language processing and its subsets have numerous practical applications within today’s world, like healthcare diagnoses or online customer service.
With natural language processing and machine learning working behind the scenes, all you need to focus on is using the tools and helping them to improve their natural language understanding. Text analysis is a critical component of natural language understanding (NLU). It involves techniques that nlu machine learning analyze and interpret text data using tools such as statistical models and natural language processing (NLP). Sentiment analysis is the process of determining the emotional tone or opinions expressed in a piece of text, which can be useful in understanding the context or intent behind the words.
Statistical NLP (1990s–2010s)
In this project-oriented course you will develop systems and algorithms for robust machine understanding of human language. The course draws on theoretical concepts from linguistics, natural language processing, and machine learning. Natural language generation is another subset of natural language processing. While natural language understanding focuses on computer reading comprehension, natural language generation enables computers to write.
- Generally, computer-generated content lacks the fluidity, emotion and personality that makes human-generated content interesting and engaging.
- While translations are still seldom perfect, they’re often accurate enough to convey complex meaning with reasonable accuracy.
- In the second half of the course, you will pursue an original project in natural language understanding with a focus on following best practices in the field.
- NLU is specifically scoped to understanding text by extracting meaning from it in a machine-readable way for future processing.
- Chess and language present more or less infinite possibilities, and neither have been “solved” for good.
- Get underneath your data using text analytics to extract categories, classification, entities, keywords, sentiment, emotion, relations and syntax.

Chatbot vs ChatGPT: Understanding the Differences & Features
NLG systems enable computers to automatically generate natural language text, mimicking the way humans naturally communicate — a departure from traditional computer-generated text. 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.
Common NLP tasks include tokenization, part-of-speech tagging, lemmatization, and stemming. A number of advanced NLU techniques use the structured information provided by NLP to understand a given user’s intent. While creating a chatbot like the example in Figure 1 might be a fun experiment, its inability to handle even minor typos or vocabulary choices is likely to frustrate users who urgently need access to Zoom.

With a greater level of intelligence, NLP helps computers pick apart individual components of language and use them as variables to extract only relevant features from user utterances. But while playing chess isn’t inherently easier than processing language, chess does have extremely well-defined rules. There are certain moves each piece can make and only a certain amount of space on the board for them to move. Computers thrive at finding patterns when provided with this kind of rigid structure. 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.
In NLU, they are used to identify words or phrases in a given text and assign meaning to them. NLP and NLU are similar but differ in the complexity of the tasks they can perform. NLP focuses on processing and analyzing text data, such as language translation or speech recognition. 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.
NLU can be used as a tool that will support the analysis of an unstructured text
But despite the many advances in NLU over the last decade, there’s still a ways to go before it’s reliably accurate. In addition to monitoring content that originates outside the walls of the enterprise, organizations are seeing value in understanding internal data as well, and here, more traditional NLP still has value. Organizations are using NLP technology to enhance the value from internal document and data sharing. The use of NLP technology gives individuals and departments the ability to have tailored text, generated by the system using NLG approaches.
