NLU is used to give the users of the device a response in their natural language, instead of providing them a list of possible answers. Whether you’re on your computer all day or visiting a company page seeking support via a chatbot, it’s likely you’ve interacted with a form of natural language understanding. When it comes to customer support, companies utilize NLU in artificially intelligent chatbots and assistants, so that they can triage customer tickets as well as understand customer feedback. Forethought’s own customer support AI uses NLU as part of its comprehension process before categorizing tickets, as well as suggesting answers to customer concerns. Natural language understanding (NLU) technology plays a crucial role in customer experience management. By allowing machines to comprehend human language, NLU enables chatbots and virtual assistants to interact with customers more naturally, providing a seamless and satisfying experience.

Additionally, statistical machine learning and deep learning techniques are typically used to improve accuracy and flexibility of the language processing models. Natural language understanding is a subset of natural language processing that determines the meaning of a sentence through syntactic and semantic analysis of text and speech. Automated reasoning is the process of using computers to reason about something. However, automated reasoning can help machines to understand human language. In the case of NLU, automated reasoning can be used to reason about the meaning of human language. The most common example of natural language understanding is voice recognition technology.

Machine language translation

Natural Language Generation is the production of human language content through software. 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. NLU enables computers https://www.metadialog.com/ to understand the sentiments expressed in a natural language used by humans, such as English, French or Mandarin, without the formalized syntax of computer languages. NLU also enables computers to communicate back to humans in their own languages. While natural language processing (NLP), natural language understanding (NLU), and natural language generation (NLG) are all related topics, they are distinct ones.

  • The goal of a chatbot is to minimize the amount of time people need to spend interacting with computers and maximize the amount of time they spend doing other things.
  • 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.
  • 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.
  • ” Customer service and support applications are ideal for having NLU provide accurate answers with minimal hands-on involvement from manufacturers and resellers.

It’s important for developers to consider the difference between NLP and NLU when designing conversational search functionality because it impacts the quality of interpretation of what users say and mean. In a world of artificial intelligence (AI), data serves as the foundation for machine learning (ML) models to identify trends … 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.


Although this field is far from perfect, the application of NLU has facilitated great strides in recent years. While translations are still seldom perfect, they’re often accurate enough to convey complex meaning with reasonable accuracy. Hence the breadth and depth of “understanding” aimed at by a system determine both the complexity of the system (and the implied challenges) and the types of applications it can deal with.

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. NLP is an umbrella term which encompasses any and everything related to what is nlu making machines able to process natural language—be it receiving the input, understanding the input, or generating a response. If you’re looking for ways to understand your customers better, NLU is a great place to start. You can learn about their needs, wants, and pain points by analyzing their language.

However, NLU systems face numerous challenges while processing natural language inputs. One of the major applications of NLU in AI is in the analysis of unstructured text. Another subset of natural language processing is natural language generation.
