NICE CXone is the market leading call center software in use by thousands of customers of all sizes around the world to help them consistently deliver exceptional customer experiences. CXone is a cloud native, unified suite of applications designed to help a company holistically run its call center operations. The neural symbolic approach combines these two types of AI to create a system that can reason about human language. The neural part of the system is used to understand the meaning of words and phrases, while the symbolic part is used to reason about the relationships between them. Another challenge of NLU is that human language is constantly changing. This can make it difficult for NLU algorithms to keep up with the language changes.

It’s already being used by millions of businesses and consumers

However, when using machine translation, it will look up the words in context, which helps return a more accurate translation. Data capture refers to the collection and recording data regarding a specific object, person, or event. If a company’s systems make use of natural language understanding, the system could understand a customers’ replies to questions and automatically enter the data. NLU systems can be used to answer questions contextually, helping customers find the most relevant answers with minimum effort. It also helps voice bots figure out the intent behind the user’s speech and extract important entities from that.


Natural language understanding and generation are two computer programming methods that allow computers to understand human speech. Natural language generation is the process of turning computer-readable data into human-readable text. For example, if you wanted to build a bot that could talk back to you as though it were another person, you might use NLG software to make sure it sounded like someone else was typing for them . Natural language understanding focuses on machine reading comprehension through grammar and context, enabling it to determine the intended meaning of a sentence. With the availability of APIs like Twilio Autopilot, NLU is becoming more widely used for customer communication. This gives customers the choice to use their natural language to navigate menus and collect information, which is faster, easier, and creates a better experience.

Solutions for Human Resources

In the case of chatbots created to be virtual assistants to customers, the training data they receive will be relevant to their duties and they will fail to comprehend concepts related to other topics. Just like humans, if an AI hasn’t been taught the right concepts then it will not have the information to handle complex duties. The core capability of NLU technology is to understand language in the same way humans do instead of relying on keywords to grasp concepts. As language recognition software, NLU algorithms can enhance the interaction between humans and organizations while also improving data gathering and analysis. NLP combines linguistics, data science and artificial intelligence to allow computers to process large amounts of language data. NLP aims to allow computers to comprehend the data – not just read it – including the subtle nuances of language.

NLU is one of the most important areas of NLP as it makes it possible for machines to understand us. Natural language processing seeks to convert unstructured language data into a structured data format to enable machines to understand speech and text and formulate relevant, contextual responses. Its subtopics include natural language processing and natural language generation. Learn how to extract and classify text from unstructured data with MonkeyLearn’s no-code, low-code text analysis tools. 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. John Ball, cognitive scientist and inventor of Patom Theory, supports this assessment.

The what is nlu engine, using Natural Language Understanding, would likely respond by showing search results that offer flight ticket purchases. The management of context in natural-language understanding can present special challenges. A large variety of examples and counter examples have resulted in multiple approaches to the formal modeling of context, each with specific strengths and weaknesses. In 1970, William A. Woods introduced the augmented transition network to represent natural language input.

Answering questions and semantic parsing

Transform customer, employee, brand, and product experiences to help increase sales, renewals and grow market share. Request a demo and begin your natural language understanding journey in AI. Simply put, using previously gathered and analyzed information, computer programs are able to generate conclusions.

To pass the test, a human evaluator will interact with a machine and another human at the same time, each in a different room. 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. A task called word sense disambiguation, which sits under the NLU umbrella, makes sure that the machine is able to understand the two different senses that the word “bank” is used. All these sentences have the same underlying question, which is to enquire about today’s weather forecast. For instance, you are an online retailer with data about what your customers buy and when they buy them.

Instead of phrase structure rules ATNs used an equivalent set of finite state automata that were called recursively. ATNs and their more general format called „generalized ATNs“ continued to be used for a number of years. If not, the process is started over again with a different set of rules. This is repeated until a specific rule is found which describes the structure of the sentence. They consist of nine sentence- or sentence-pair language understanding tasks, similarity and paraphrase tasks, and inference tasks.

  • In such cases, salespeople in the physical stores used to solve our problem and recommended us a suitable product.

It involves numerous tasks that break down natural language into smaller elements in order to understand the relationships between those elements and how they work together. Common tasks include parsing, speech recognition, part-of-speech tagging, and information extraction. Conversational interfaces are powered primarily by natural language processing , and a key subset of NLP is natural language understanding . The terms NLP and NLU are often used interchangeably, but they have slightly different meanings.

What is an example of NLU?

A useful business example of NLU is customer service automation. With text analysis solutions like MonkeyLearn, machines can understand the content of customer support tickets and route them to the correct departments without employees having to open every single ticket.

Natural language includes slang and idioms, not in formal writing but common in everyday conversation. Natural language is the way we use words, phrases, and grammar to communicate with each other. Using a tokenizer to break up the input into individual words, or „tokens.“
