While natural language understanding focuses on computer reading comprehension, natural language generation enables computers to write. NLG is the process of producing a human language text response based on some data input. This text can also be converted into a speech format through text-to-speech services. Overall, natural language understanding is a complex field that continues to evolve with the help of machine learning and deep learning technologies. It plays an important role in customer service and virtual assistants, allowing computers to understand text in the same way humans do. NLU uses natural language processing (NLP) to analyze and interpret human language.

While there may be some general guidelines, it’s often best to loop through them to choose the right one. Another popular application of NLU is chat bots, also known as dialogue agents, who make our interaction with computers more human-like. At the most basic level, bots need to understand how to map our words into actions and use dialogue to clarify uncertainties. At the most sophisticated level, they should be able to hold a conversation about anything, which is true artificial intelligence.

It also means they can comprehend what the speaker or writer is trying to say and its intent. Businesses could use this for customer service applications such as chatbots and virtual assistants. On the other hand, natural language processing is an umbrella term to explain the whole process of turning unstructured data into structured data. NLP helps technology to engage in communication using natural human language. As a result, we now have the opportunity to establish a conversation with virtual technology in order to accomplish tasks and answer questions.

While NLP can be used for tasks like language translation, speech recognition, and text summarization, NLU is essential for applications like chatbots, virtual assistants, and sentiment analysis. NLP is a subfield of Artificial Intelligence that focuses on the interaction between computers and humans in natural language. It involves techniques for analyzing, understanding, and generating human language. NLP enables machines to read, understand, and respond to natural language input. In short, the potential benefits of using NLU in real-world applications are abundant. By leveraging NLU to understand natural language, businesses can gain valuable insights into customer sentiment, automate processes, and improve efficiency.


Cem’s work in Hypatos was covered by leading technology publications like TechCrunch and Business Insider. He graduated from Bogazici University as a computer engineer and holds an MBA from Columbia Business School. Therefore, their predicting abilities improve as they are exposed to more data. Akkio offers an intuitive interface that allows users to quickly select the data they need. Even your website’s search can be improved with NLU, as it can understand customer queries and provide more accurate search results.

NLU is an artificial intelligence method that interprets text and any type of unstructured language data. Natural Language Understanding, or NLU, is a field of Artificial Intelligence that allows conversational AI solutions to determine user intent. It is powered by AI, and allows for patterns in human language to be understood.

By making sense of more-complex and delineated search requests, NLU more quickly moves customers from browsing to buying. If you only have NLP, then you can’t interpret the meaning of a sentence or phrase. Without NLU, your system won’t be able to respond appropriately in natural language. The semantic analysis involves the process of assigning the correct meaning to each word in a sentence. NLU powered by neural networks helps determine the intent of an email by scanning language usage for topic and sentiment. Both the Natural Language Processing and Natural Language Understanding markets are growing rapidly, thanks to the increased adoption of voice assistants and artificial intelligence.

Keeping your team satisfied at work isn’t purely altruistic — happy people are 13% more productive than their dissatisfied colleagues. Unhappy support agents will struggle to give your customers the best experience. Plus, a higher employee retention rate will save your company money on recruitment and training. Once you’ve identified trends — across all of the different channels — you can use these insights to make informed decisions on how to improve customer satisfaction. NLU is a subdiscipline of NLP, and refers specifically to identifying the meaning of whatever speech or text is being processed.

It involves techniques that 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. Natural language generation is another subset of natural language processing.

There’s a growing need to be able to analyze huge quantities of text contextually

In NLU systems, this output is often generated by computer-generated speech or chat interfaces, which mimic human language patterns and demonstrate the system’s ability to process natural language input. One of the major applications of NLU in AI is in the analysis of unstructured text. But with natural language processing and machine learning, this is changing fast. Alexa is exactly that, allowing users to input commands through voice instead of typing them in. Throughout the years various attempts at processing natural language or English-like sentences presented to computers have taken place at varying degrees of complexity. Some attempts have not resulted in systems with deep understanding, but have helped overall system usability.

In short, NLU brings a lot of varied business value; however, it is important to remember that NLU is only a subset of NLP capabilities, which are required to provide “smart” answers to “smart” questions. NLU only tells half of the story, or rather, it only asks the question, a smart search engine delivers the answer. Chatbots, when equipped with Artificial Intelligence (AI) and Natural Language Understanding(NLU), can generate more human-like conversations with the users. Digital assistants equipped with the NLU abilities can deduce what the user ‘actually’ means, regardless of how it is expressed. Customer support agents can spend hours manually routing incoming support tickets to the right agent or team, and giving each ticket a topic tag.

In recent times, the popularity of artificial intelligence (AI) has led to the emergence of new concepts. Beside Lisp, a number of alternative functional programming languages have been developed. To continue, the word vector of w1 and the hidden state h1 are fed into RNN to predict the third word.

  • NLP enables machines to read, understand, and respond to natural language input.
  • These systems will assist with diagnosis, analysis, and decision-support tasks, revolutionizing these industries’ operations.
  • Depending on your business, you may need to process data in a number of languages.

The input and output are customized to respond in preferred international or regional languages to enhance user convenience. While natural language processing (or NLP) and natural language understanding are related, they’re not the same. NLP is an umbrella term that covers every aspect of communication between humans and an AI model — from detecting the language a person is speaking, to generating appropriate responses. For businesses, it’s important to know the sentiment of their users and customers overall, and the sentiment attached to specific themes, such as areas of customer service or specific product features. Early attempts at natural language processing were largely rule-based and aimed at the task of translating between two languages. IBM Watson NLP Library for Embed, powered by Intel processors and optimized with Intel software tools, uses deep learning techniques to extract meaning and meta data from unstructured data.

NLU is an efficient tool, since it peels away layers of noise in order to get to meaning. The efficiencies that NLU brings will get more and more valuable as the amount of data increases. NLU is an evolution and subset of another technology known as Natural Language Processing, or NLP. Dependency parsing is a fundamental technique in Natural Language Processing (NLP) that plays a pivotal role in understanding the… However, the rapid integration of NLU into our lives will raise ethical, legal, and privacy concerns. Regulations will need to adapt to ensure responsible NLU use, and the development of privacy-preserving NLU technologies will be pivotal in safeguarding user data.

NLU takes the communication from the user, interprets the meaning communicated, and classifies it into the appropriate intents. It uses multiple processes, including text categorization, content analysis, and sentiment analysis which allows it to handle and understand a variety of inputs. NLU has opened up new possibilities for businesses and individuals, enabling them to interact with machines more naturally. From customer support to data capture and machine translation, NLU applications are transforming how we live and work. After preprocessing, NLU models use various ML techniques to extract meaning from the text.

While current NLU models excel at surface-level comprehension, reaching the rank of cognitive reasoning and abstract thinking exhibited by humans is a formidable aspiration. Language is not static; it evolves, introducing new words, phrases, and slang. NLU systems must adapt to these linguistic changes to remain relevant and effective in understanding and processing contemporary language. As technology evolves, NLU systems are increasingly required to process and interpret multiple modalities, including text, speech, images, and videos.
