NLP vs NLU vs NLG: Understanding the Differences by Tathagata Medium

NLP vs NLU vs. NLG: Understanding Chatbot AI

Thanks to our unique retrieval-augmented multimodal approach, now we can overcome the limitations of LLMs such as hallucinations and limited knowledge. Knowledge-Enhanced biomedical language models have proven to be more effective at knowledge-intensive BioNLP tasks than generic LLMs. In 2020, researchers created the Biomedical Language Understanding and Reasoning Benchmark (BLURB), a comprehensive benchmark and leaderboard to accelerate the development of biomedical NLP. This book is for managers, programmers, directors – and anyone else who wants to learn machine learning. To pass the test, a human evaluator will interact with a machine and another human at the same time, each in a different room.

These technologies have continued to evolve and improve with the advancements in AI, and have become industries in and of themselves. Natural language understanding interprets the meaning that the user communicates and classifies it into proper intents. For example, it is relatively easy for humans who speak the same language to understand each other, although mispronunciations, choice of vocabulary or phrasings may complicate this. NLU is responsible for this task of distinguishing what is meant by applying a range of processes such as text categorization, content analysis and sentiment analysis, which enables the machine to handle different inputs. In addition to natural language understanding, natural language generation is another crucial part of NLP. While NLU is responsible for interpreting human language, NLG focuses on generating human-like language from structured and unstructured data.

Businesses use AI for everything from identifying fraudulent insurance claims to improving customer service to predicting the best schedule for preventive maintenance of factory machines. And if you use a Nest thermostat, unlock your phone with facial recognition, or have ever said, “Alexa, turn off the lights,” you’re using artificial intelligence in your everyday life. NLU is a crucial part of ensuring these applications are accurate while extracting important business intelligence from customer interactions. In the near future, conversation intelligence powered by NLU will help shift the legacy contact centers to intelligence centers that deliver great customer experience.

NLU and NLP technologies address these challenges by going beyond mere word-for-word translation. They analyze the context and cultural nuances of language to provide translations that are both linguistically accurate and culturally appropriate. By understanding the intent behind words and phrases, these technologies can adapt content to reflect local idioms, customs, and preferences, thus avoiding potential misunderstandings or cultural insensitivities. One of the key advantages of using NLU and NLP in virtual assistants is their ability to provide round-the-clock support across various channels, including websites, social media, and messaging apps. This ensures that customers can receive immediate assistance at any time, significantly enhancing customer satisfaction and loyalty.

Natural Language Understanding (NLU) is a field of NLP that allows computers to understand human language in more than just a grammatical sense. It also means they can comprehend what the speaker or writer is trying to say and its intent. Businesses could use this for customer service applications such as chatbots and virtual assistants. Natural language processing is generally more suitable for tasks involving data extraction, text summarization, and machine translation, among others. Meanwhile, NLU excels in areas like sentiment analysis, sarcasm detection, and intent classification, allowing for a deeper understanding of user input and emotions.

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. These are all good reasons for giving natural language understanding a go, but how do you know if the accuracy of an algorithm will be sufficient? Consider the type of analysis it will need to perform and the breadth of the field. Analysis ranges from shallow, such as word-based statistics that ignore word order, to deep, which implies the use of ontologies and parsing.

With text analysis solutions like MonkeyLearn, machines can understand the content of customer support tickets and route them to the correct departments without employees having to open every single ticket. Not only does this save customer support teams hundreds of hours, but it also helps them prioritize urgent tickets. Before a computer can process unstructured text into a machine-readable format, first machines need to understand the peculiarities of the human language.

Natural Language Understanding Examples

Such tailored interactions not only improve the customer experience but also help to build a deeper sense of connection and understanding between customers and brands. NLU is technically a sub-area of the broader area of natural language processing (NLP), which is a sub-area of artificial intelligence (AI). Many NLP tasks, such as part-of-speech or text categorization, do not always require actual understanding in order to perform accurately, but in some cases they might, which leads to confusion between these two terms. As a rule of thumb, an algorithm that builds a model that understands meaning falls under natural language understanding, not just natural language processing. On the other hand, natural language understanding is concerned with semantics – the study of meaning in language.

More importantly, the concept of attention allows them to model long-term dependencies even over long sequences. Transformer-based LLMs trained on huge volumes of data can autonomously predict the next contextually relevant token in a sentence with an exceptionally high degree of accuracy. Instead, machines must know the definitions of words and sentence structure, along with syntax, sentiment and intent. It’s a subset of NLP and It works within it to assign structure, rules and logic to language so machines can “understand” what is being conveyed in the words, phrases and sentences in text. On our quest to make more robust autonomous machines, it is imperative that we are able to not only process the input in the form of natural language, but also understand the meaning and context—that’s the value of NLU. This enables machines to produce more accurate and appropriate responses during interactions.

These examples are a small percentage of all the uses for natural language understanding. Anything you can think of where you could benefit from understanding what natural language is communicating is likely a domain for NLU. However, syntactic analysis is more related to the core of NLU examples, where the literal meaning behind a sentence is assessed by looking into its syntax and how words come together. Using tokenisation, NLP processes can replace sensitive information with other values to protect the end user. With lemmatisation, the algorithm dissects the input to understand the root meaning of each word and then sums up the purpose of the whole sentence.

But over time, natural language generation systems have evolved with the application of hidden Markov chains, recurrent neural networks, and transformers, enabling more dynamic text generation in real time. However, the grammatical correctness or incorrectness does not always correlate with the validity of a phrase. Think of the classical example of a meaningless yet grammatical sentence “colorless green ideas sleep furiously.” Even more, in real life, meaningful sentences often contain minor errors and can be classified as ungrammatical. Human interaction allows for errors in the produced text and speech compensating them through excellent pattern recognition and drawing additional information from the context.

Creating a perfect code frame is hard, but thematic analysis software makes the process much easier. Behind the scenes, sophisticated algorithms like hidden Markov chains, recurrent neural networks, n-grams, decision trees, naive bayes, etc. work in harmony to make it all possible. This machine doesn’t just focus on grammatical structure but highlights necessary information, actionable insights, and other essential details.

The first one is the rule-based modeling of human language, and the second includes machine learning (ML) and deep learning (DL). 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.

Syntactic analysis applies rules about sentence structure (syntax) to derive part of the meaning of what’s being said. The combination of these analysis techniques turns raw speech into logical meaning. NLU is a subcategory of NLP that enables machines to understand the incoming audio or text. Its counterpart is natural language generation (NLG), which allows the computer to “talk back.” When the two team up, conversations with humans are possible. Now that we have defined the scope of NLP and the diversity of problems that are included in it, we can define and explain the concept of natural language understanding (NLU). NLU is a subfield within NLP, and it includes all the algorithms that try to understand natural language.

Most other bots out there are nothing more than a natural language interface into an app that performs one specific task, such as shopping or meeting scheduling. Interestingly, this is already so technologically challenging that humans often hide behind the scenes. Google released the word2vec tool, and Facebook followed by publishing their speed optimized deep learning modules. nlp and nlu Since language is at the core of many businesses today, it’s important to understand what NLU is, and how you can use it to meet some of your business goals. In this article, you will learn three key tips on how to get into this fascinating and useful field. People can express the same idea in different ways, but sometimes they make mistakes when speaking or writing.

This tool is designed with the latest technologies to provide sentiment analysis. It helps you grow your business and make changes according to customer feedback. If you want to create robust autonomous machines, then it’s important that you cannot only process the input but also understand the meaning behind the words. That’s why simple tasks such as sentence structure, syntactic analysis, and order of words are easy. When a call does make its way to the agent, NLU can also assist them by suggesting next best actions while the call is still ongoing.

SHRDLU could understand simple English sentences in a restricted world of children’s blocks to direct a robotic arm to move items. 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. This sentence doesn’t have any sentiment in it, and it was probably never seen by the algorithm before (remember that we trained the algorithm with movies reviews).

The product they have in mind aims to be effortless, unsupervised, and able to interact directly with people in an appropriate and successful manner. Traditional interactive voice response (IVR) systems greet customers at the beginning of inbound calls, allow callers to interact with menus, and facilitate self-service. Most people know IVRs as the system that makes them “Press 1 for sales” and often makes it really hard to talk to an agent. This is a very important point that you’ll need to define before starting to implement anything.

Sometimes an NLU approach is impossible because you don’t have enough data to train your model. For example, if you want to deal with a language that is not widely spoken or you are working in a particular field (medicine, transport, etc) that uses very specific terminology, an NLU approach may not be able to process it. The idea is that when given a sentence, the algorithm returns Positive or Negative taking into account the sentiment of the sentence. Imagine that you want to apply that solution to a well-defined scope – for example, movie reviews. So, a possible solution could be to download a corpus of movie reviews and train a neural network to detect the sentiment of the sentence. Semantic problems are better suited to NLU because the concepts of “understanding” and “semantic” are similar.

This is forcing contact centers to explore new ways to use technology to ensure better customer experience, customer satisfaction, and retention. From this list, the first three tasks (NER, POS tagging and syntactic parsing) are syntactic processes, while the last four tasks are semantic.The complexity and mechanisms needed to resolve each one of those problems vary. The syntactic problems are easier to solve, and there are a lot of mechanisms and algorithms (some of them pretty old) to deal with them. Most of them are easy to define and you can implement an acceptable solution without applying machine learning.

NLG is used to generate a semantic understanding of the original document and create a summary through text abstraction or text extraction. In text extraction, pieces of text are extracted from the original document and put together into a shorter version while maintaining the same information content. Text abstraction, the original document is phrased in a linguistic way, text interpreted and described using new concepts, but the same information content is maintained. NLP is an interdisciplinary field that combines multiple techniques from linguistics, computer science, AI, and statistics to enable machines to understand, interpret, and generate human language. This is in contrast to NLU, which applies grammar rules (among other techniques) to “understand” the meaning conveyed in the text. In order for systems to transform data into knowledge and insight that businesses can use for decision-making, process efficiency and more, machines need a deep understanding of text, and therefore, of natural language.

Enhance contact center automation with NLU tools developed over 24+ years

NLP excels in tasks that are related to processing and generating human-like language. It dives much deeper insights and understands language’s meaning, context, and complexities. 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, also known as NLU, is a term that refers to how computers understand language spoken and written by people.

Systems that are both very broad and very deep are beyond the current state of the art. Natural language understanding is the first step in many processes, such as categorizing text, gathering news, archiving individual pieces of text, and, on a larger scale, analyzing content. Real-world examples of NLU range from small tasks like issuing short commands based on comprehending text to some small degree, like rerouting an email to the right person based on basic syntax and a decently-sized lexicon. Much more complex endeavors might be fully comprehending news articles or shades of meaning within poetry or novels. Artificial intelligence is transforming business models and the way many of us live our lives.

NLU enables human-computer interaction by comprehending commands in natural languages, such as English and Spanish. The most common way is to use a supervised learning algorithm, like linear regression or support vector machines. You can foun additiona information about ai customer service and artificial intelligence and NLP. These algorithms work by taking in examples of correct answers and using them to predict what’s accurate on new examples. The semantic analysis involves the process of assigning the correct meaning to each word in a sentence. The syntactic analysis involves the process of identifying the grammatical structure of a sentence. You can choose the smartest algorithm out there without having to pay for it. Most algorithms are publicly available as open source.

Because they can understand human speech and user intent, they’re capable of executing a much broader set of tasks, including facilitating complete, end-to-end self-service. And if self-service isn’t in the cards, these chatbots can gather information and pass it to an agent, which reduces handle times and labor costs. These techniques have been shown to greatly improve the accuracy of NLP tasks, such as sentiment analysis, machine translation, and speech recognition. As these techniques continue to develop, we can expect to see even more accurate and efficient NLP algorithms.

Still, NLU is based on sentiment analysis, as in its attempts to identify the real intent of human words, whichever language they are spoken in. This is quite challenging and makes NLU a relatively new phenomenon compared to traditional NLP. However, as discussed in this guide, NLU (Natural Language Understanding) is just as crucial in AI language models, even though it is a part of the broader definition of NLP.

Ultimately, we can say that natural language understanding works by employing algorithms and machine learning models to analyze, interpret, and understand human language through entity and intent recognition. This technology brings us closer to a future where machines can truly understand and interact with us on a deeper level. Natural language understanding is a subset of natural language processing that’s defined by what it extracts from unstructured text, which identifies nuance in language and derives hidden or abstract meanings from text or voice. 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. It extracts pertinent details, infers context, and draws meaningful conclusions from speech or text data.

These technologies enable companies to sift through vast volumes of data to extract actionable insights, a task that was once daunting and time-consuming. By applying NLU and NLP, businesses can automatically categorize sentiments, identify trending topics, and understand the underlying emotions and intentions in customer communications. This automated analysis provides a comprehensive view of public perception and customer satisfaction, revealing not just what customers are saying, but how they feel about products, services, brands, and their competitors. These technologies have transformed how humans interact with machines, making it possible to communicate in natural language and have machines interpret, understand, and respond in ways that are increasingly seamless and intuitive.

Natural languages arose as the perfect means of communication and mutual understanding. These are English, German, French, Italian, and the other 7,139 languages in the world. However, concerning technologies, we have artificially created languages that help us communicate with and become understandable by computers. These are Java, C, Python, JavaScript, etc., which are programming languages, technical, existing as code. Pursuing the goal to create a chatbot that would be able to interact with a human in a human-like manner — and finally, to pass the Turing test, businesses and academia are investing more in NLP and NLU techniques.

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. NLU focuses on understanding human language, while NLP covers the interaction between machines and natural language. Basically, with this technology, the aim is to enable machines to understand and interpret human language.

This has implications for various industries, including journalism, marketing, and e-commerce. Automated reasoning is a subfield of cognitive science that is used to automatically prove mathematical theorems or make logical inferences about a medical diagnosis.

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. To understand the specificity of NLP and NLU, let’s discuss each concept separately. A key difference is that NLU focuses on the meaning of the text and NLP focuses more on the structure of the text.

From the time we started, we have been using AI technologies like NLP, NLU & NLG to boost the contact center performance with live conversation intelligence. Our AI engine is able to uncover insights from 100% of customer interactions that maximizes frontline team performance through coaching and end-to-end workflow automation. With our AI technology, companies can act faster with real-time insights and guidance to improve performance, from more sales to higher retention. 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.

It involves numerous tasks that break down natural language into smaller elements in order to understand the relationships between those elements and how they work together. Common tasks include parsing, speech recognition, part-of-speech tagging, and information extraction. NLU leverages advanced machine learning and deep learning techniques, employing intricate algorithms and neural networks to enhance language comprehension. Integrating external knowledge sources such as ontologies and knowledge graphs is common in NLU to augment understanding. Semantic Role Labeling (SRL) is a pivotal tool for discerning relationships and functions of words or phrases concerning a specific predicate in a sentence.

Understanding the sentiment and urgency of customer communications allows businesses to prioritize issues, responding first to the most critical concerns. The history of NLU and NLP goes back to the mid-20th century, with significant milestones marking its evolution. In 1957, Noam Chomsky’s work on “Syntactic Structures” introduced the concept of universal grammar, laying a foundational framework for understanding the structure of language that would later influence NLP development.

NLP is an already well-established, decades-old field operating at the cross-section of computer science, artificial intelligence, and, increasingly, data mining. The ultimate of NLP is to read, decipher, understand, and make sense of the human languages by machines, taking certain tasks off the humans and allowing for a machine to handle them instead. Common real-world examples of such tasks are online chatbots, text summarizers, auto-generated keyword tabs, as well as tools analyzing the sentiment of a given text. Natural Language Processing (NLP) refers to the branch of artificial intelligence or AI concerned with giving computers the ability to understand text and spoken words in much the same way human beings can.

Accurately translating text or speech from one language to another is one of the toughest challenges of natural language processing and natural language understanding. NLP can be used to integrate chatbots into websites, allowing users to interact with the business directly through their website. This will help improve customer satisfaction and save company costs by reducing the need for human employees who would otherwise be required to provide these services. Across various industries and applications, NLP and NLU showcase their unique capabilities in transforming the way we interact with machines. By understanding their distinct strengths and limitations, businesses can leverage these technologies to streamline processes, enhance customer experiences, and unlock new opportunities for growth and innovation. Natural language processing primarily focuses on syntax, which deals with the structure and organization of language.
