NLU is the process of understanding a natural language and extracting meaning from it. NLU can be used to extract entities, relationships, and intent from a natural language input. Both should lead to the ordering of a new laptop from the company’s service catalog, but NLU is what allows AI to precisely define the intent of a given user no matter how they say it. As you can imagine, this requires a deep understanding of grammatical structures, language-specific semantics, dependency parsing, and other techniques.

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. In a previous post we talked about how organizations can benefit from machine learning (especially natural language processing) without making a big investment. Now we’ll delve deeper into natural language processing (NLP), explain the differences between NLP and natural language understanding (NLU), and offer some tips for choosing the best solution for your company. The Markov model is a mathematical method used in statistics and machine learning to model and analyze systems that are able to make random choices, such as language generation. Markov chains start with an initial state and then randomly generate subsequent states based on the prior one.

What do we mean when we Talk about NLG?

Natural language processing and its subsets have numerous practical applications within today’s world, like healthcare diagnoses or online customer service. Bharat Saxena has over 15 years of experience in software product development, and has worked in various stages, from coding to managing a product. With BMC, he supports the AMI Ops Monitoring for Db2 product development team. Bharat holds Masters in Data Science and Engineering from BITS, Pilani.

  • NLG also encompasses text summarization capabilities that generate summaries from in-put documents while maintaining the integrity of the information.
  • 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.
  • Automated reasoning is a subfield of cognitive science that is used to automatically prove mathematical theorems or make logical inferences about a medical diagnosis.
  • So, taking into account that the NLU approach generalizes better than a traditional NLP approach in some semantic tasks, why don’t we always use NLU for semantic tasks?.
  • 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.
  • More specifically, they use natural language understanding (NLU) to understand better exactly what it is you are asking.

The next step is to consider the importance of each and every word in a given sentence. In English, some words appear more frequently than others such as “is”, “a”, “the”, “and”. Lemmatization removes inflectional endings and returns the canonical form of a word or lemma. We will look at specific, real-world use cases of these tasks later. From a business perspective, harnessing the power of NLU has enormous potential.

Natural Language Generation Tools

NLU is a subset of artificial intelligence (AI), which seeks to create machines that can think and act in ways that are similar to humans. Now, businesses can easily integrate AI into their operations with Akkio’s no-code AI for NLU. With Akkio, you can effortlessly build models capable of understanding English and any other language, by learning the ontology of the language and its syntax.

How we use artificial intelligence (AI) in our day to day lives is increasing at pace. Lexical Ambiguity exists in the presence of two or more possible meanings of the sentence within a single word. It helps you to discover the intended effect by applying a set of rules that characterize cooperative dialogues.

The Key Difference Between NLP and NLU

Natural language generation (NLG) is the use of artificial intelligence (AI) programming to produce written or spoken narratives from a data set. NLG is related to human-to-machine and machine-to-human interaction, including computational linguistics, natural language processing (NLP) and natural language understanding (NLU). It is a technology that can lead to more efficient call qualification because software employing NLU can be trained to understand jargon from specific industries such as retail, banking, utilities, and more. For example, the meaning of a simple word like “premium” is context-specific depending on the nature of the business a customer is interacting with.

This includes basic tasks like identifying the parts of speech in a sentence, as well as more complex tasks like understanding the meaning of a sentence or the context of a conversation. 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. As we mentioned earlier, NLG is a subset of NLP and it tries to understand the meaning of a sentence using syntactic and semantic analysis. The syntactic analysis looks at the grammar and the structure of a sentence and semantics, on the other hand, infers the intended meaning.

As a result, insurers should take into account the emotional context of the claims processing. As a result, if insurance companies choose to automate claims processing with chatbots, they must be certain of the chatbot’s emotional and NLU skills. For instance, the address of the home a customer wants to cover has an impact on the underwriting process since it has a relationship with burglary risk. NLP-driven machines can automatically extract data from questionnaire forms, and risk can be calculated seamlessly.

Interestingly, this is already so technologically challenging that humans often hide behind the scenes. The further into the future we go, the more prevalent automated encounters will be in the customer journey. Customers expect quick answers to their questions, and 69% of people like the promptness with which chatbots serve them.

NLP or NLU: How to Choose the Best Option for Your Project

It is easy to confuse common terminology in the fast-moving world of machine learning. For example, the term NLU is often believed to be interchangeable with the term NLP.


CNNs can be used for different classification tasks in NLP. A convolution is a window that slides over a larger input data with an emphasis on a subset of the input matrix. Getting your data in the right dimensions is extremely important for any learning algorithm.

In the example mentioned before, the first approach(training with only the movie review corpus) will probably yield better results with a new review than the NLU approach. If we take an NLU approach, instead of training our model with only movie reviews, we use more data (such as a Wikipedia corpus). Then the model will probably be able to detect that the sentence doesn’t have any sentiment information and give the expected result. If accuracy is paramount, go only for specific tasks that need shallow analysis. If accuracy is less important, or if you have access to people who can help where necessary, deepening the analysis or a broader field may work.

Q3.If the Input given by the Customer is Speech, then what is used to analyse the data?

However, NLU lets computers understand “emotions” and “real meanings” of the sentences. Natural languages are different from formal or constructed languages, which have a different origin and development path. For example, programming languages including C, Java, Python, and many more were created for a specific reason.

  • NLG can be used to generate natural language summaries of data or to generate natural language instructions for a task such as how to set up a printer.
  • While there may be some general guidelines, it’s often best to loop through them to choose the right one.
  • Now you know that regular Tropicana is easily available, but 100% is hard to come by, so you call up a few stores beforehand to see where it’s available.
  • The main goal is to make meaning out of text in order to perform certain tasks automatically such as spell check, translation, for social media monitoring tools, and so on.
  • Illustrations for two articles about natural language processing (NLP) and understanding (NLU).
  • Natural Language Processing(NLP) is a subset of Artificial intelligence which involves communication between a human and a machine using a natural language than a coded or byte language.

That means, soon enough, the next time you have a conversation online, you might not even realize you’re talking with a machine. It was then that OpenAI, a non-profit AI research company, announced they built an AI model that essentially writes coherent paragraphs of text at scale. The model was called GPT-2 and it learned how to write this well by analyzing eight million web pages.

How Natural Language Understanding Works

Close to human narratives automatically explain insights that otherwise could be lost in tables, charts, and graphs via natural language and act as a companion throughout the data discovery process. Besides, NLG coupled with NLP are the core of chatbots and other automated chats and assistants that provide us with everyday support. NLP and NLU are fascinating fields that provide a lot of great opportunities for businesses to create innovative, competitive solutions. We hope this post has helped you understand the key differences between NLP and NLU and identify the important questions you’ll need to answer before you implement NLP or NLU in your product.

NLP can help insurance companies with data-driven decisions providing insights into customer preferences and usage patterns. Financial institutions use NLP to analyze market data, reduce risks, and make better decisions. NLP and other natural language solutions can also assist in financial crime detection. It just goes to show that low-hanging fruit may create value faster for your organization, while teaching you the basics of natural language generation.

  • These are the two hypotheses relating to the way humans store words of a language in their memory.
  • NLP is a branch of AI that deals with designing programs for machines that will allow them to process the language that humans use.
  • A vital element of this algorithm is that it assumes that all the feature values are independent.
  • In other words, it helps to predict the parts of speech for each token.
  • It enables computers to evaluate and organize unstructured text or speech input in a meaningful way that is equivalent to both spoken and written human language.
  • The noun it describes, version, denotes multiple iterations of a report, enabling us to determine that we are referring to the most up-to-date status of a file.

His current active areas of research are conversational AI and algorithmic bias in AI. Going back to our weather enquiry example, it is NLU which enables the machine to understand that those three different questions have the same underlying weather forecast query. 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.

Why is NLP better?

NLP is important because it helps resolve ambiguity in language and adds useful numeric structure to the data for many downstream applications, such as speech recognition or text analytics.

Language is how we all communicate and interact, but machines have long lacked the ability to understand human language. A lot of acronyms get tossed around when discussing artificial intelligence, and NLU is no exception. NLU, a subset of AI, is an umbrella term that covers NLP and natural language generation (NLG). In essence, NLP focuses on the words that were said, while NLU focuses on what those words actually signify. Some users may complain about symptoms, others may write short phrases, and still, others may use incorrect grammar.
