AIMultiple informs hundreds of thousands of businesses (as per similarWeb) including 60% of Fortune 500 every month. Throughout his career, Cem served as a tech consultant, tech buyer and tech entrepreneur.

Where is natural language understanding used?

If someone says they are going to the “bank,” they could be going to a financial institution or to the edge of a river. Without a strong relational model, the resulting response isn’t likely to be what the user intends to find. The key aim of any Natural Language Understanding-based tool is to respond appropriately to the input in a way that the user will understand. 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. There is Natural Language Understanding at work as well, helping the voice assistant to judge the intention of the question.

  • Common NLP tasks include tokenization, part-of-speech tagging, lemmatization, and stemming.
  • Voice-based intelligent personal assistants such as Siri, Cortana, and Alexa also benefit from advances in NLU that enable better understanding of user requests and provision of more-personalized responses.
  • Intent recognition identifies what the person speaking or writing intends to do.
  • This has opened up countless possibilities and applications for NLU, ranging from chatbots to virtual assistants, and even automated customer service.
  • In addition to processing natural language similarly to a human, NLG-trained machines are now able to generate new natural language text—as if written by another human.

Additionally, NLU establishes a data structure specifying relationships between phrases and words. While humans can do this naturally in conversation, machines need these analyses to understand what humans mean in different texts. While NLP analyzes and comprehends the text in a document, NLU makes it possible to communicate with a computer using natural language. Natural Language Understanding (NLU) connects with human communication’s deeper meanings and purposes, such as feelings, objectives, or motivation. It employs AI technology and algorithms, supported by massive data stores, to interpret human language. Without sophisticated software, understanding implicit factors is difficult.

NLU technology enables computers and other devices to understand and interpret human language by analyzing and processing the words and syntax used in communication. This has opened up countless possibilities and applications for NLU, ranging from chatbots to virtual assistants, and even automated customer service. In this article, we will explore the various applications and use cases of NLU technology and how it is transforming the way we communicate with machines.

NLU, a subset of natural language processing (NLP) and conversational AI, helps conversational AI applications to determine the purpose of the user and direct them to the relevant solutions. Build fully-integrated bots, trained within the context of your business, with the intelligence to understand human language and help customers without human oversight. For example, allow customers to dial into a knowledgebase and get the answers they need. NLG is the process of generating a human language text response from data input. Natural language processing (NLP), natural language understanding (NLU), and natural language generation (NLG) are all distinct topics. Developers with no machine learning experience can also build their models via this service.

Natural language understanding (NLU) is a branch of computer science that focuses on machine reading comprehension through grammar and context, allowing it to determine the intended meaning of a sentence. Syntax refers to a sentence’s grammatical structure, whereas semantics refers to its intended meaning. NLU also creates a relevant ontology, which is a data structure that defines the relationships between words and phrases. NLU (Natural Language Understanding) and NLP (Natural Language Processing) are crucial in understanding human language in this context. Because they both deal with Natural Language, these terms are sometimes used interchangeably.

Natural language understanding is how a computer program can intelligently understand, interpret, and respond to human speech. Natural language generation is the process by which a computer program creates content based on human speech input. There are several benefits of natural language understanding for both humans and machines. Humans can communicate more effectively with systems that understand their language, and those machines can better respond to human needs. Agents can also help customers with more complex issues by using NLU technology combined with natural language generation tools to create personalized responses based on specific information about each customer’s situation.

Translation means searching for the exact analog of a word in another language, but it fails when it comes to phrases and idioms. In such a case, it’s better to use transcreation, which conveys the sentence’s meaning in the targeted language without a word-by-word translation. Natural https://www.metadialog.com/ Language Understanding enables machines to understand a set of text by working to understand the language of the text. There are so many possible use-cases for NLU and NLP and as more advancements are made in this space, we will begin to see an increase of uses across all spaces.

Natural language understanding (NLU) is a subfield of natural language processing (NLP), which involves transforming human language into a machine-readable format. With the rise of chatbots, virtual assistants, and voice assistants, the need for machines to understand natural language has become more crucial. In this article, we’ll delve deeper into what is natural language understanding and explore some of its exciting possibilities. Word-Sense Disambiguation is the process of determining the meaning, or sense, of a word based on the context that the word appears in. Word sense disambiguation often makes use of part of speech taggers in order to contextualize the target word.

What are NLP, NLU, and NLG, and Why should you know about them and their differences?

From customer support to data capture and machine translation, NLU applications are transforming how we live and work. NLU helps computers to understand human language by understanding, analyzing and interpreting basic speech parts, separately. Natural language understanding (NLU) is a technical concept within the larger topic of natural language processing. NLU is the process responsible for translating natural, human words into a format that a computer can interpret. Essentially, before a computer can process language data, it must understand the data. The last place that may come to mind that utilizes NLU is in customer service AI assistants.


As technology advances, we can expect to see more sophisticated NLU applications that will continue to improve our daily lives. It is best to compare the performances of different solutions by using objective metrics. The greater the capability of NLU models, the better they are in predicting speech context. In fact, one of the factors driving the development of ai chip devices with larger model training sizes is the relationship between the NLU model’s increased computational capacity and effectiveness (e.g GPT-3). Check out this guide to learn about the 3 key pillars you need to get started. NLU is necessary in data capture since the data being captured needs to be processed and understood by an algorithm to produce the necessary results.
