What is Natural Language Understanding NLU?

Nlp Vs Nlu: Understand A Language From Scratch

nlu definition

Natural Language Generation is the production of human language content through software. It transforms data into a language translation that we can understand. It is often used in response to Natural Language Understanding processes. NLU is an AI-powered solution for recognizing patterns in a human language. It enables conversational AI solutions to accurately identify the intent of the user and respond to it.

Using complex algorithms that rely on linguistic rules and AI machine training, Google Translate, Microsoft Translator, and Facebook Translation have become leaders in the field of “generic” language translation. Both NLP and NLU aim to make sense of unstructured data, but there is a difference between the two. Natural language Understanding is mainly concerned with the meaning of language. NLU doesn’t focus on the word formation or punctuation in a sentence.

NLP undertakes various tasks such as parsing, speech recognition, part-of-speech tagging, and information extraction. It works by taking and identifying various entities together (named entity recognition) and identification of word patterns. The word patterns are identified using methods such as tokenization, stemming, and lemmatization.

Its prime objective is to bring out the actual intent of the speaker. 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. However, Computers use much more data than humans do to solve problems, so computers are not as easy for people to understand as humans are.

What is the future of natural language?

In 1971, Terry Winograd finished writing SHRDLU for his PhD thesis at MIT. SHRDLU could understand simple English sentences in a restricted world of children’s blocks to direct a robotic arm to move items. Both types of training are highly effective in helping individuals improve their communication skills, but there are some key differences between them. NLP offers more in-depth training than and it also focuses on teaching people how to use neuro-linguistic programming techniques in their everyday lives. This allowed it to provide relevant content for people who were interested in specific topics.

Natural Language Understanding seeks to intuit many of the connotations and implications that are innate in human communication such as the emotion, effort, intent, or goal behind a speaker’s statement. It uses algorithms and artificial intelligence, backed by large libraries of information, to understand our language. NLU, the technology behind intent recognition, enables companies to build efficient chatbots.

This allowed LinkedIn to improve its users’ experience and enable them to get more out of their platform. Both NLU and NLP use supervised learning, which means that they train their models using labelled data. NLP models are designed to describe the meaning of sentences whereas NLU models are designed to describe the meaning of the text in terms of concepts, relations and attributes. For example, it is the process of recognizing and understanding what people say in social media posts.

For example, programming languages including C, Java, Python, and many more were created for a specific reason. Turn nested phone trees into simple “what can I help you with” voice prompts. Ideally, your NLU solution should be able to create a highly developed interdependent network of data and responses, allowing insights to automatically trigger actions.

This article will answer the above questions and give you a comprehensive understanding of Natural Language Understanding (NLU). From the million records NLP can selectively choose the relevant one based on the individual’s query. Text extraction can be used for “extracting required information’ in the shortest timespan.


It works by building the algorithm and training the model on large amounts of data analyzed to understand what the user means when they say something. While both understand human language, NLU communicates with untrained individuals to learn and understand their intent. In addition to understanding words and interpreting meaning, NLU is programmed to understand meaning, despite common human errors, such as mispronunciations or transposed letters and words. 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.

In this context, another term which is often used as a synonym is Natural Language Understanding (NLU). 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.

If the evaluator is not able to reliably tell the difference between the response generated by the machine and the other human, then the machine passes the test and is considered to be exhibiting “intelligent” behavior. 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. All these sentences have the same underlying question, which is to enquire about today’s weather forecast. Natural languages are different from formal or constructed languages, which have a different origin and development path.

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 the help of NLU, and machine learning computers can analyze the data. While natural language processing (NLP), natural language understanding (NLU), and natural language generation (NLG) are all related topics, they are distinct ones. Given how they intersect, they are commonly confused within conversation, but in this post, we’ll define each term individually and summarize their differences to clarify any ambiguities. Also, NLP processes a large amount of human data and focus on use of machine learning and deep learning techniques. Knowledge of that relationship and subsequent action helps to strengthen the model.
