What is Natural Language Understanding & How Does it Work?

It can be used to translate text from one language to another and even generate automatic translations of documents. This allows users to read content in their native language without relying on human translators. When we hear or read  something our brain first processes that information and then we understand it. That is because we can’t process all information – we can only process information that is within our familiar realm. Natural Language Processing, or NLP, is made up of Natural Language Understanding and Natural Language Generation. NLU helps the machine understand the intent of the sentence or phrase using profanity filtering, sentiment detection, topic classification, entity detection, and more.

NLP converts unstructured data into a structured format to help computers clearly understand speech and written commands and produce relevant responses. NLP and NLU technologies are essential for natural language processing applications such as automatic speech recognition, machine translation, and chatbots. By working together, NLP and NLU technologies can interpret language and make sense of it for applications that need to understand and respond to human language.

While it can’t write entire blog posts for you, it can generate briefs that cover all the questions that should be answered, the keywords that should appear, and the internal and external links that should be included. Imagine you had a tool that could read and interpret content, find its strengths and its flaws, and then write blog posts that meet the needs of both search engines and your users. NLP and NLU will analyze content on the stock market and break it down, while NLG will take the applicable data and turn it into a templated story for your site.

To interpret a text and understand its meaning, NLU must first learn its context, semantics, sentiment, intent, and syntax. Semantics and syntax are of utmost significance in helping check the grammar and meaning of a text, respectively. Though NLU understands unstructured data, part of its core function is to convert text into a structured data set that a machine can more easily consume. 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. NLU technologies continue to evolve rapidly, driven by advances in deep learning, the availability of large-scale datasets, and ongoing research efforts.

In practical terms, NLP makes it possible to understand what a human being says, to process the data in the message, and to provide a natural language response. In both NLP and NLU, context plays an essential role in determining the meaning of words and phrases. NLP algorithms use context to understand the meaning of words and phrases, while NLU algorithms use context to understand the sentiment and intent behind a statement. Without context, both NLP and NLU would be unable to accurately interpret language.

NLU is more helpful in data mining to assess consumer behavior and attitude. With sentiment analysis, brands can tap the social media domain to monitor the customer’s feedback through negative and positive comments. By closely observing the negative comments, businesses successfully identify and address the pain points.

The NLU field is dedicated to developing strategies and techniques for understanding context in individual records and at scale. NLU systems empower analysts to distill large volumes of unstructured text into coherent groups without reading them one by one. This allows us to resolve tasks such as content analysis, topic modeling, machine translation, and question answering at volumes that would be impossible to achieve using human effort alone. NLP stands for Natural Language Processing and it is a branch of AI that uses computers to process and analyze large volumes of natural language data. Given the complexity and variation present in natural language, NLP is often split into smaller, frequently-used processes. Common tasks in NLP include part-of-speech tagging, speech recognition, and word embeddings.

In NLU, machine learning models improve over time as they learn to recognize syntax, context, language patterns, unique definitions, sentiment, and intent. NLU, on the other hand, is a subset of NLP that focuses on understanding the meaning behind human language. It involves teaching computers to analyze human language at a deeper level, beyond just the surface meaning of words and sentences. NLU is concerned with tasks such as entity recognition, semantic analysis, and intent detection. The ultimate goal of NLU is to create machines that can understand the meaning of human language and respond appropriately. NLP is a branch of AI that deals with the automatic processing and analysis of human language.

It involves techniques like sentiment analysis, named entity recognition, and coreference resolution. By understanding human language, NLU enables machines to provide personalized and context-aware responses in chatbots and virtual assistants. It plays a crucial role in information retrieval systems, allowing machines to accurately retrieve relevant information based on user queries. In this case, NLU can help the machine understand the contents of these posts, create customer service tickets, and route these tickets to the relevant departments. This intelligent robotic assistant can also learn from past customer conversations and use this information to improve future responses. NLU is the ability of a machine to understand and process the meaning of speech or text presented in a natural language, that is, the capability to make sense of natural language.

If a developer wants to build a simple chatbot that produces a series of programmed responses, they could use NLP along with a few machine learning techniques. However, if a developer wants to build an intelligent contextual assistant capable of having sophisticated natural-sounding conversations with users, they would need NLU. NLU is the component that allows the contextual assistant to understand the intent of each utterance by a user.

NLU allows computer applications to infer intent from language even when the written or spoken language is flawed. The future of NLU and NLP is promising, with advancements in AI and machine learning techniques enabling more accurate and sophisticated language understanding and processing. These innovations will continue to influence how humans interact with computers and machines. The power of collaboration between NLP and NLU lies in their complementary strengths. While NLP focuses on language structures and patterns, NLU dives into the semantic understanding of language.

  • For computers to get closer to having human-like intelligence and capabilities, they need to be able to understand the way we humans speak.
  • Conversational interfaces are powered primarily by natural language processing (NLP), and a key subset of NLP is natural language understanding (NLU).
  • Natural language processing is a field of computer science that works with human languages.
  • If you produce templated content regularly, say a story based on the Labor Department’s quarterly jobs report, you can use NLG to analyze the data and write a basic narrative based on the numbers.

For example, an NLG system might be used to generate product descriptions for an e-commerce website or to create personalized email marketing campaigns. With FAQ chatbots, businesses can reduce their customer care workload (see Figure 5). As a result, they do not require both excellent NLU skills and intent recognition.

Its main aim is to develop algorithms and techniques that empower machines to process and manipulate textual or spoken language in a useful way. As such, it deals with lower-level tasks such as tokenization and POS tagging. NLP and NLU have made these possible and continue shaping the virtual communication field.
