how does natural language understanding nlu work

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. NLU is more powerful than NLP when understanding human communication as it considers the context of the conversation. If you’re starting from scratch, we recommend Spokestack’s NLU training data format. This will give you the maximum amount of flexibility, as our format supports several features you won’t find elsewhere, like implicit slots and generators.

Where is natural language understanding used?

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.

By the end, you’ll have the knowledge to understand which AI solutions can cater to your organization’s unique requirements. NLP gives computers the ability to understand spoken words and text the same as humans do. It divides the entire paragraph into different sentences for better understanding.


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. Natural language understanding and generation are two computer programming methods that allow computers to understand human speech. Simplilearn’s AI ML Certification is designed after our intensive Bootcamp learning model, so you’ll be ready to apply these skills as soon as you finish the course.

For a detailed discussion of design issues for speech interfaces (see Speech Interface Design). The primary challenge with Natural Language Understanding is the difficulty represented by natural languages themselves. A natural language consists not only of words but also rules about how those words work together to form a grammatical construct that is unique from any other natural language. In a paper he wrote called “Computing Machinery and Intelligence, Alan Turing proposed it. Together, NLU and natural language generation enable NLP to function effectively, providing a comprehensive language processing solution.

Why is Natural Language Understanding important?

By combining their strengths, businesses can create more human-like interactions and deliver personalized experiences that cater to their customers’ diverse needs. This integration of language technologies is driving innovation and improving user experiences across various industries. NLP and NLU have unique strengths and applications as mentioned above, but their true power lies in their combined use. Integrating both technologies allows AI systems to process and understand natural language more accurately. The fascinating world of human communication is built on the intricate relationship between syntax and semantics.

NLU is used in data mining and analysis to extract insights from large volumes of textual data. This can help businesses make data-driven decisions and improve their strategies. NLU can be used to create automated content generation systems, which can help businesses produce written content, such as product descriptions, news articles, and more.

What are the applications of NLU?

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. It should be able  to understand complex sentiment and pull out emotion, effort, intent, motive, intensity, and more easily, and make inferences and suggestions as a result. Entity recognition identifies which distinct entities are present in the text or speech, helping the software to understand the key information.

But NLU can convert that into a precise symbolic form that’s suitable for computation mixing the best of precise computer language and natural language. With AI-driven thematic analysis software, you can generate actionable insights effortlessly. In the healthcare industry, NLU can help providers analyze patient data and provide insights to improve patient care.

After all, different sentences can mean the same thing, and, vice versa, the same words can mean different things depending on how they are used. For example, in NLU, various ML algorithms are used to identify the sentiment, perform Name Entity Recognition (NER), process semantics, etc. NLU algorithms often operate on text that has already been standardized by text pre-processing steps. But before any of this natural language processing can happen, the text needs to be standardized.

It involves the processing of human language to extract relevant meaning from it. This meaning could be in the form of intent, named entities, or other aspects of human language. With the rise of chatbots, virtual assistants, and voice assistants, the need for machines to understand natural language has become more crucial. In this article, we’ll delve deeper into what is natural language understanding and explore some of its exciting possibilities.

In this context, another term which is often used as a synonym is Natural Language Understanding (NLU). How we use artificial intelligence (AI) in our day to day lives is increasing at pace. Multiple NLP development efforts, algorithms, and language resources are managed and coordinated centrally within the Saga framework. NLU capabilities are powered by both Patterns Matching (for precision and ease of editing) and Machine Learning (for broad coverage and automatic learning). Accuracy is the number of correct predictions a system makes divided by the total number of predictions it makes. Precision is how many of the predictions are correct, while recall is the number of correct predictions divided by the total number of items that should have been predicted.

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. Idiomatic expressions, such as “break a leg” or “raining cats and dogs,” can be particularly challenging for NLU systems, as their meanings cannot be derived from the individual words alone. The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. As we highlighted above, the purpose of NLU is to interpret human communication in context.

The Impact of NLU in Customer Experience

However, our ability to process information is limited to what we already know. Similarly, machine learning involves interpreting information to create knowledge. Understanding NLP is the first step toward exploring the frontiers of language-based AI and ML. NLP is a subset of AI that helps machines understand human intentions or human language. Pushing the boundaries of possibility, natural language understanding (NLU) is a revolutionary field of machine learning that is transforming the way we communicate and interact with computers. NLU applications include chatbots, sentiment analysis, language translation, voice assistants, and text summarization, among others.
