How Does Natural Language Understanding NLU Work in AI?

how does natural language understanding nlu work

In simpler terms; a deep learning model will be able to perceive and understand the nuances of human language. Natural Language Understanding (NLU) is the ability of a computer to understand human language. You can use it for many applications, such as chatbots, voice assistants, and automated translation services. Natural language processing (NLP) is an interdisciplinary domain which is concerned with understanding natural languages as well as using them to enable human–computer interaction.

Sentiment analysis can help determine the overall attitude of customers towards the company, while content analysis can reveal common themes and topics mentioned in customer feedback. Natural Language Understanding (NLU) refers to the process by which machines are able to analyze, interpret, and generate human language. Sophisticated contract analysis software helps to provide insights which are extracted from contract data, so that the terms in all your contracts are more consistent. The technology fuelling this is indeed NLU or natural language understanding. NLP is a process where human-readable text is converted into computer-readable data. Today, it is utilised in everything from chatbots to search engines, understanding user queries quickly and outputting answers based on the questions or queries those users type.

Accelerate your business growth as an Independent Software Vendor (ISV) by innovating with IBM. Partner with us to deliver enhanced commercial solutions embedded with AI to better address clients’ needs. The Lite plan is perpetual for 30,000 NLU items and one custom model per calendar month. Once you reach the 30,000 NLU items limit in a calendar month, your NLU instance will be suspended and reactivated on the first day of next calendar month. We recommend the Lite Plan for POC’s and the standard plan for higher usage production purposes. Quickly extract information from a document such as author, title, images, and publication dates.

Distinguishing between sarcastic remarks and genuine statements can be exceedingly tricky. As a result, NLU systems may occasionally misinterpret the intended meaning, leading to inaccurate analyses. As AI becomes more sophisticated, NLU will become more accurate and will be able to handle more complex tasks. NLU is already being used in various applications, and we can only expect that number to grow in the future. It can help with tasks such as automatically extracting information from patient records, understanding doctor’s notes, and helping patients with self-care. NLU is more powerful than NLP when understanding human communication as it considers the context of the conversation.

Five most commonly used NLU terms

According to various industry estimates only about 20% of data collected is structured data. The remaining 80% is unstructured data—the majority of which is unstructured text data that’s unusable for traditional methods. Just think of all the online text you consume daily, social media, news, research, product websites, and more. GLUE and its superior SuperGLUE are the most widely used benchmarks to evaluate the performance of a model on a collection of tasks, instead of a single task in order to maintain a general view on the NLU performance.

Natural languages complex and many NLP tasks are ill-posed for mathematically precise algorithmic solutions. A dialogue system is a machine-based system that aims to communicate with humans through conversation via text, speech, images, and other communication modes as input or output. Dialogues systems are broadly implemented in banking, client services, human resources management, education, governments, etc. Dialogue systems can be categorized into task-oriented approaches and nontask-oriented approaches (Chen, Liu, Yin, & Tang, 2018). Task-oriented approaches aim to complete specific tasks for end-users, such as booking hotels or recommending products (e.g., see Qin, Xu, Che, Zhang, & Liu, 2020; Xie et al., 2022). Nontask-oriented ones, such as a personal companion chatbot, usually concentrate on continuing a diverse, vivid, and relevant conversation with end-users on an open domain (e.g., Gritta, Lampouras, & Iacobacci, 2021).

The most common example of natural language understanding is voice recognition technology. Voice recognition software can analyze spoken words and convert them into text or other data that the computer can process. Natural language understanding (NLU) is a branch of artificial intelligence (AI) that uses computer software to understand input in the form of sentences using text or speech. NLU enables human-computer interaction by analyzing language versus just words. Natural language understanding works by deciphering the overall meaning (or intent) of a text.

We also examine several key use cases and provide recommendations on how to get started with your own natural language solutions. 6 min read – IBM Power is designed for AI and advanced workloads so that enterprises can inference and deploy AI algorithms on sensitive data on Power systems. By implementing NLU, chatbots that would otherwise only be able to supply barebone replies can use keyword recognition to amplify their conversational capabilities. NLU-powered chatbots can provide instant, 24/7 customer support at every stage of the customer journey. Overall, NLU technology is a powerful tool for making computers more human-like. By using NLP techniques to interpret and understand language, NLU technology can help computers better understand and respond to requests and commands, making them more capable and user-friendly.

It uses algorithms and artificial intelligence, backed by large libraries of information, to understand our language. The event calculus can be used to address the problem of story understanding, which consists of taking a story as input, understanding it, and then answering questions about it. Commonsense reasoning can be used to fill in details not explicitly stated in the input story. The Discrete Event Calculus Reasoner program can be used to build detailed models of a story, which represent the events that occur and the properties that are true or false at various times. Chatbots are now taking the internet by the storm and even though creating a powerful chatbot experience can be difficult, there are some clear winners in the industry that heavily utilizes natural language processing. The Facebook Messenger bot along with the Wit.AI acquisition are emerging as the leaders in the industry in engaging the B2C market, especially since the FB messenger interface is everywhere.

Machine learning is at the core of natural language understanding (NLU) systems. It allows computers to “learn” from large data sets and improve their performance over time. Machine learning algorithms use statistical methods to process data, recognize patterns, and make predictions.

Customers expect to be heard as individuals

Overall, when measuring NLU performance, accuracy, precision, recall, F1 score, and generalization should all be taken into account. These metrics can help developers identify areas of improvement, which can help improve the accuracy and performance of their NLU models. NLP can process text from grammar, structure, typo, and point of view—but it will be NLU that will help the machine infer the intent behind the language text. So, even though there are many overlaps between NLP and NLU, this differentiation sets them distinctly apart. Natural languages are different from formal or constructed languages, which have a different origin and development path. For example, programming languages including C, Java, Python, and many more were created for a specific reason.
