What’s the difference between NLU and NLP

nlu vs nlp

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. Answering customer calls and directing them to the correct department or person is an everyday use case for NLUs. Implementing an IVR system allows businesses to handle customer queries 24/7 without hiring additional staff or paying for overtime hours. For example, when a human reads a user’s question on Twitter and replies with an answer, or on a large scale, like when Google parses millions of documents to figure out what they’re about. The benefits of NLP in this area are also shown in quick data processing, which gives analysts an advantage in performing essential tasks. NLP’s main objective is to bridge the gap between natural language communication and computer comprehension (machine language).

  • This could include personalized recommendations, customized content, and personalized chatbot interactions.
  • Data scientists can examine notes from customer care teams to determine areas where customers wish the company to perform better or analyze social media comments to see how their brand is performing.
  • The remaining 80% is unstructured data—the majority of which is unstructured text data that’s unusable for traditional methods.
  • As AI and NLP become more ubiquitous, there will be a growing need to address ethical considerations around privacy, data security, and bias in AI systems.
  • This could result in more reliable language translation, accurate sentiment analysis, and faster speech recognition.
  • All this has sparked a lot of interest both from commercial adoption and academics, making NLP one of the most active research topics in AI today.

The question “what’s the weather like outside?” can be asked in hundreds of ways. With NLU, computer applications can recognize the many variations in which humans say the same things. NLU algorithms provide a number of benefits, such as improved accuracy, faster processing, and better understanding of natural language input. NLU algorithms are able to identify the intent of the user, extract entities from the input, and generate a response. NLU algorithms are also able to identify patterns in the input data and generate a response. NLU algorithms are able to process natural language input and extract meaningful information from it.

Data Capture

To put it simply, NLP deals with the surface level of language, while NLU deals with the deeper meaning and context behind it. While NLP can be used for tasks like language translation, speech recognition, and text summarization, NLU is essential for applications like chatbots, virtual assistants, and sentiment analysis. As a result, algorithms search for associations and correlations to infer what the sentence’s most likely meaning is rather than understanding the genuine meaning of human languages. Automated encounters are becoming an ever bigger part of the customer journey in industries such as retail and banking.

This can provide a better customer experience but is more complicated to implement. Companies can also use natural language understanding software in marketing campaigns by targeting specific groups of people with different messages based on what they’re already interested in. Natural language processing is the process of turning human-readable text into computer-readable data. It’s used in everything from online search engines to chatbots that can understand our questions and give us answers based on what we’ve typed. NLU is a subfield of NLP (Natural Language Processing), which deals with the processing of human language by computers. NLP involves a range of tasks, including text classification, language translation, text generation, and more.

Advanced Technology Development

Thus, NLP models can conclude that “Paris is the capital of France” sentence refers to Paris in France rather than Paris Hilton or Paris, Arkansas. In addition to processing natural language similarly to a human, NLG-trained machines are now able to generate new natural language text—as if written by another human. All this has sparked a lot of interest both from commercial adoption and academics, making NLP one of the most active research topics in AI today.

This information was unavailable for computer-assisted analysis and could not be evaluated in any organized manner before deep learning-based NLP models. NLP enables analysts to search enormous amounts of free text for pertinent information. On the other hand, natural language understanding is concerned with semantics – the study of meaning in language.

When are machines intelligent?

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. Without it, the assistant won’t be able to understand what a user means throughout a conversation. And if the assistant doesn’t understand what the user means, it won’t respond appropriately or at all in some cases. NLG, on the other hand, involves techniques to generate natural language using data in any form as input.

  • Many pre-trained models are accessible through the Hugging Face Python framework for various NLP tasks.
  • For example, NLU and NLP are being used to interpret clinical notes and extract information that can be used for medical records.
  • Natural language processing primarily focuses on syntax, which deals with the structure and organization of language.
  • NLU is also closely related to Natural Language Generation (NLG), which deals with the generation of human language by computers.
  • NLU is often used to create automated customer service agents, natural language search engines, and other applications that require a machine to understand human language.
  • Without context, both NLP and NLU would be unable to accurately interpret language.

As NLP algorithms and models improve, they can process and generate natural language content more accurately and efficiently. This could result in more reliable language translation, accurate sentiment analysis, and faster speech recognition. A computer program’s capacity to comprehend natural language, or human language as spoken and written, is known as natural language processing (NLP).

NLP can study language and speech to do many things, but it can’t always understand what someone intends to say. NLU enables computers to understand what someone meant, even if they didn’t say it perfectly. However, the full potential of NLP cannot be realized without the support of NLU. And so, understanding NLU is the second step toward enhancing the accuracy and efficiency of your speech recognition and language translation systems.

Words and phrases can have several meanings depending on context, and sentences can be arranged in a multitude of ways to express different meanings. To help machines analyze and interpret the intricacies of human languages, NLP algorithms employ a variety of approaches such as machine learning, deep learning and statistical modelling. These algorithms are trained on copious volumes of labeled data to identify and learn patterns and correlations between words and phrases. NLP is a field that deals with the interactions between computers and human languages. It’s aim is to make computers interpret natural human language in order to understand it and take appropriate actions based on what they have learned about it. Natural language processing is a category of machine learning that analyzes freeform text and turns it into structured data.

People start asking questions about the pool, dinner service, towels, and other things as a result. Such tasks can be automated by an NLP-driven hospitality chatbot (see Figure 7). 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. It’s important to not over-optimise the human traits of these bots, however, at the risk of alienating customers.

NLP gives computers the ability to understand spoken words and text the same as humans do. Improvements in computing and machine learning have increased the power and capabilities of NLU over the past decade. We can expect over the next few years for NLU to become even more powerful and more integrated into software. Natural language understanding is complicated, and seems metadialog.com like magic, because natural language is complicated. A clear example of this is the sentence “the trophy would not fit in the brown suitcase because it was too big.” You probably understood immediately what was too big, but this is really difficult for a computer. Voice recognition microphones can identify words but are not yet smart enough to understand voice tones.

NLU technologies use advanced algorithms to understand the context of language and interpret its meaning. This allows the computer to understand a user’s intent and respond appropriately. NLP utilizes a variety of techniques to make sense of language, such as tokenization, part-of-speech tagging, and named entity recognition. Tokenization is the process of breaking down text into individual words or phrases. Part-of-speech tagging assigns each word a tag to indicate its part of speech, such as noun, verb, adjective, etc. Named entity recognition identifies named entities in text, such as people, places, and organizations.


Due to the uncanny valley effect, interactions with machines can become very discomforting. Put simply, bots should be programmed to mirror human traits without making painstaking attempts to emulate them. After all, they’re taking care of routine queries, freeing up time for the agents so they can focus on tasks where their interpersonal skills and insights are truly needed. The most sophisticated NLG model, GPT-3, or Generative Pre-trained Transformer 3, can write poetry, prose and even computer coding that is hard to distinguish from that created by humans. It transforms data into understandable language, writing sentences, paragraphs and even complete articles that seem natural to human readers. One part of NLP is Natural Language Understanding (NLU), which uses deep learning to process and comprehend text and its meanings, emotions, syntax and relationships.


The algorithm can tell, for instance, how many of the mentions of brand A were favorable and how many were unfavorable when that brand is referenced in X texts. Intent detection, which predicts what the speaker or writer might do based on the text they are producing, can also be a helpful application of this technology. Before the development of NLP technology, people communicated with computers using computer languages, i.e., codes. NLP enabled computers to understand human language in written and spoken forms, facilitating interaction.
