With unstructured content only growing for most organizations, it’s important to have ways to continue to capture, analyze and make sense of this valuable data, and understanding the differences between NLP vs. NLU is a crucial first step. However, NLP, which has been in development for decades, is still limited in terms of what the computer can actually understand. Adding machine learning and other AI technologies to NLP leads to natural language understanding (NLU), which can enhance a machine’s ability to understand what humans say. As it stands, NLU is considered to be a subset of NLP, focusing primarily on getting machines to understand the meaning behind text information.
Natural Language Understanding(NLU) is an area of artificial intelligence to process input data provided by the user in natural language say text data or speech data. It is a way that enables interaction between a computer and a human in a way like humans do using natural languages like English, French, Hindi etc. NLP takes input text in the form of natural language, converts it into a computer language, processes it, and returns the information as a response in a natural language.

Keep reading to learn more about the ongoing struggles with ambiguity, data needs, and ensuring responsible AI. This evaluation helps identify any areas of improvement and guides further fine-tuning efforts.
When it comes to natural language, what was written or spoken may not be what was meant. In the most basic terms, NLP looks at what was said, and NLU looks at what was meant. People can say identical things in numerous ways, and they may make mistakes when writing or speaking. They may use the wrong words, write fragmented sentences, and misspell or mispronounce words. NLP can analyze text and speech, performing a wide range of tasks that focus primarily on language structure. However, it will not tell you what was meant or intended by specific language.
While NLU has challenges like sensitivity to context and ethical considerations, its real-world applications are far-reaching—from chatbots to customer support and social media monitoring. Symbolic AI uses human-readable symbols that represent real-world entities or concepts. Logic is applied in the form of an IF-THEN structure embedded into the system by humans, who create the rules.
In such cases, salespeople in the physical stores used to solve our problem and recommended us a suitable product. In the age of conversational commerce, such a task is done by sales chatbots that understand user intent and help customers to discover a suitable product for them via natural language (see Figure 6). Sentiment analysis and intent identification are not necessary to improve user experience if people tend to use more conventional sentences or expose a structure, such as multiple choice questions. Have you ever wondered how Alexa, ChatGPT, or a customer care chatbot can understand your spoken or written comment and respond appropriately? NLP and NLU, two subfields of artificial intelligence (AI), facilitate understanding and responding to human language. Follow this guide to gain practical insights into natural language understanding and how it transforms interactions between humans and machines.
Think of the classical example of a meaningless yet grammatical sentence “colorless green ideas sleep furiously”. Even more, in the 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 by excellent pattern recognition and drawing additional information from the context. This shows the lopsidedness of the syntax-focused analysis and the need for a closer focus on multilevel semantics. 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.

Furthermore, NLU enables computer programmes to deduce purpose from language, even if the written or spoken language is flawed. NLU, however, understands the idiom and interprets the user’s intent as being hungry and searching for a nearby restaurant. 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 hard coding of rules can be used to manipulate the understanding of symbols. 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. Additionally, these AI-driven tools can handle a vast number of queries simultaneously, reducing wait times and freeing up human agents to focus on more complex or sensitive issues.
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. NLP is an umbrella term which encompasses any and everything related to making machines able to process natural language—be it receiving the input, understanding the input, or generating a response. In 1970, William A. Woods introduced the augmented transition network (ATN) to represent natural language input.[13] Instead of phrase structure rules ATNs used an equivalent set of finite state automata that were called recursively. ATNs and their more general format called “generalized ATNs” continued to be used for a number of years.
This process allows the Model to adapt to your specific use case and enhances performance. Pre-trained NLU models can significantly speed up the development process and provide better performance. You’ll need a diverse dataset that includes examples of user queries or statements and their corresponding intents and entities.
A subfield of artificial intelligence and linguistics, NLP provides the advanced language analysis and processing that allows computers to make this unstructured human language data readable by machines. It can use many different methods to accomplish this, from tokenization, lemmatization, machine translation and natural language understanding. Ultimately, we can say that natural language understanding works by employing algorithms and machine learning models to analyze, Chat GPT 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. NLG is another subcategory of NLP that constructs sentences based on a given semantic. After NLU converts data into a structured set, natural language generation takes over to turn this structured data into a written narrative to make it universally understandable.
While computational linguistics has more of a focus on aspects of language, natural language processing emphasizes its use of machine learning and deep learning techniques to complete tasks, like language translation or question answering. Natural language processing works by taking unstructured data and converting it into a structured data format. It does this through the identification of named entities (a process called named entity recognition) and identification of word patterns, using methods like tokenization, stemming, and lemmatization, which examine the root forms of words.
Both NLP& NLU have evolved from various disciplines like artificial intelligence, linguistics, and data science for easy understanding of the text. NLP or natural language processing is evolved from computational linguistics, which aims to model natural human language data. For instance, a simple chatbot can be developed using NLP without the need for NLU. However, for a more intelligent and contextually-aware assistant capable of sophisticated, natural-sounding conversations, natural language understanding becomes essential. It enables the assistant to grasp the intent behind each user utterance, ensuring proper understanding and appropriate responses.
NLP and NLU are transforming marketing and customer experience by enabling levels of consumer insights and hyper-personalization that were previously unheard of. From decoding feedback and social media conversations to powering multilanguage engagement, these technologies are driving connections through cultural nuance and relevance. Where meaningful relationships were once constrained by human limitations, NLP and NLU liberate authentic interactions, heralding a new era for brands and consumers alike. The promise of NLU and NLP extends beyond mere automation; it opens the door to unprecedented levels of personalization and customer engagement. These technologies empower marketers to tailor content, offers, and experiences to individual preferences and behaviors, cutting through the typical noise of online marketing.
The tokens are then analyzed for their grammatical structure, including the word’s role and different possible ambiguities in meaning. Human language is typically difficult for computers to grasp, as it’s filled with complex, subtle and ever-changing meanings. Natural language understanding systems let organizations create products or tools that can both understand words and interpret their meaning.
We’ll also examine when prioritizing one capability over the other is more beneficial for businesses depending on specific use cases. By the end, you’ll have the knowledge to understand which AI solutions can cater to your organization’s unique requirements. Some are centered directly on the models and their outputs, others on second-order concerns, such as who has access to these systems, and how training them impacts the natural world. Since then, with the help of progress made in the field of AI and specifically in NLP and NLU, we have come very far in this quest.
For example, Wayne Ratliff originally developed the Vulcan program with an English-like syntax to mimic the English speaking computer in Star Trek. These approaches are also commonly used in data mining to understand consumer attitudes. In particular, sentiment analysis enables brands to monitor their customer feedback more closely, allowing them to cluster positive and negative social media comments and track net promoter scores.
NLP and NLU are significant terms for designing a machine that can easily understand human language, regardless of whether it contains some common flaws. Hence the breadth and depth of “understanding” aimed at by a system determine both the complexity of the system (and the implied challenges) and the types of applications it can deal with. The “breadth” of a system is measured by the sizes of its vocabulary and grammar. The “depth” is measured by the degree to which its understanding approximates that of a fluent native speaker. At the narrowest and shallowest, English-like command interpreters require minimal complexity, but have a small range of applications. Narrow but deep systems explore and model mechanisms of understanding,[25] but they still have limited application.
The rest 80% is unstructured data, which can’t be used to make predictions or develop algorithms. NLP has many subfields, including computational linguistics, syntax analysis, speech recognition, machine translation, and more. Also, NLP processes a large amount of human data and focus on use of machine learning and deep learning techniques. 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 a basic syntax and decently-sized lexicon. Much more complex endeavors might be fully comprehending news articles or shades of meaning within poetry or novels.
NLU converts input text or speech into structured data and helps extract facts from this input data. The integration of NLP algorithms into data science workflows has opened up new opportunities for data-driven decision making. Deep-learning models take as input a word embedding and, at each time state, return the probability distribution of the next word as the probability for every word in the dictionary. Pre-trained language models learn the structure of a particular language by processing a large corpus, such as Wikipedia.
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. nlu and nlp SHRDLU could understand simple English sentences in a restricted world of children’s blocks to direct a robotic arm to move items. Before booking a hotel, customers want to learn more about the potential accommodations.

NLG is a software process that turns structured data – converted by NLU and a (generally) non-linguistic representation of information – into a natural language output that humans can understand, usually in text format. NLU’s core functions are understanding unstructured data and converting text into a structured data set which a machine can more easily consume. Applications vary from relatively simple tasks like short commands for robots to MT, question-answering, news-gathering, and voice activation. For many organizations, the majority of their data is unstructured content, such as email, online reviews, videos and other content, that doesn’t fit neatly into databases and spreadsheets. Many firms estimate that at least 80% of their content is in unstructured forms, and some firms, especially social media and content-driven organizations, have over 90% of their total content in unstructured forms.
NLP-enabled systems are intended to understand what the human said, process the data, act if needed and respond back in language the human will understand. Recent years have brought a revolution in the ability of computers to understand human languages, programming languages, and even biological and chemical sequences, such as DNA and protein structures, that resemble language. The latest AI models are unlocking these areas to analyze the meanings of input text and generate meaningful, expressive output. NLU, a subset of NLP, delves deeper into the comprehension aspect, focusing specifically on the machine’s ability to understand the intent and meaning behind the text.
The sophistication of https://chat.openai.com/ technologies also allows chatbots and virtual assistants to personalize interactions based on previous interactions or customer data. This personalization can range from addressing customers by name to providing recommendations based on past purchases or browsing behavior. 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. In addition, NLU and NLP significantly enhance customer service by enabling more efficient and personalized responses. Automated systems can quickly classify inquiries, route them to the appropriate department, and even provide automated responses for common questions, reducing response times and improving customer satisfaction.
Generally, computer-generated content lacks the fluidity, emotion and personality that makes human-generated content interesting and engaging. However, NLG can be used with NLP to produce humanlike text in a way that emulates a human writer. This is done by identifying the main topic of a document and then using NLP to determine the most appropriate way to write the document in the user’s native language. 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.
A well-liked open-source natural language processing package, spaCy has solid entity recognition, tokenization, and part-of-speech tagging capabilities. The computational methods used in machine learning result in a lack of transparency into “what” and “how” the machines learn. This creates a black box where data goes in, decisions go out, and there is limited visibility into how one impacts the other. What’s more, a great deal of computational power is needed to process the data, while large volumes of data are required to both train and maintain a model. Grammar complexity and verb irregularity are just a few of the challenges that learners encounter. Now, consider that this task is even more difficult for machines, which cannot understand human language in its natural form.
NLP is used for a wide variety of language-related tasks, including answering questions, classifying text in a variety of ways, and conversing with users. For example, using NLG, a computer can automatically generate a news article based on a set of data gathered about a specific event or produce a sales letter about a particular product based on a series of product attributes. NLU makes it possible to carry out a dialogue with a computer using a human-based language. This is useful for consumer products or device features, such as voice assistants and speech to text. 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.
These technologies use machine learning to determine the meaning of the text, which can be used in many ways. Artificial intelligence is becoming an increasingly important part of our lives. However, when it comes to understanding human language, technology still isn’t at the point where it can give us all the answers. Pursuing the goal to create a chatbot that would be able to interact with human in a human-like manner — and finally to pass the Turing’s test, businesses and academia are investing more in NLP and NLU techniques. The product they have in mind aims to be effortless, unsupervised, and able to interact directly with people in an appropriate and successful manner. Semantic analysis, the core of NLU, involves applying computer algorithms to understand the meaning and interpretation of words and is not yet fully resolved.
You can foun additiona information about ai customer service and artificial intelligence and NLP. They consist of nine sentence- or sentence-pair language understanding tasks, similarity and paraphrase tasks, and inference tasks. NLU, the technology behind intent recognition, enables companies to build efficient chatbots. In order to help corporate executives raise the possibility that their chatbot investments will be successful, we address NLU-related questions in this article.
We’ve seen that NLP primarily deals with analyzing the language’s structure and form, focusing on aspects like grammar, word formation, and punctuation. On the other hand, NLU is concerned with comprehending the deeper meaning and intention behind the language. To have a clear understanding of these crucial language processing concepts, let’s explore the differences between NLU and NLP by examining their scope, purpose, applicability, and more.
This information can be used for brand monitoring, reputation management, and understanding customer satisfaction. Rasa NLU also provides tools for data labeling, training, and evaluation, making it a comprehensive solution for NLU development. Fine-tuning involves training the pre-trained Model on your dataset while keeping the initial knowledge intact. This way, you get the best of both worlds – the power of the pre-trained Model and the ability to handle your specific task. Entity extraction involves identifying and extracting specific entities mentioned in the text.
Real-world NLU applications such as chatbots, customer support automation, sentiment analysis, and social media monitoring were also explored. Natural language processing and natural language understanding language are not just about training a dataset. The computer uses NLP algorithms to detect patterns in a large amount of unstructured data. 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.
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 consists of natural language generation (NLG) concepts and natural language understanding (NLU) to achieve human-like language processing. Until recently, the idea of a computer that can understand ordinary languages and hold a conversation with a human had seemed like science fiction.
NLP uses computational linguistics, computational neuroscience, and deep learning technologies to perform these functions. NLP and NLU are closely related fields within AI that focus on the interaction between computers and human languages. It includes tasks such as speech recognition, language translation, and sentiment analysis. NLP serves as the foundation that enables machines to handle the intricacies of human language, converting text into structured data that can be analyzed and acted upon. 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.
By reviewing comments with negative sentiment, companies are able to identify and address potential problem areas within their products or services more quickly. 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. NLU can understand and process the meaning of speech or text of a natural language. To do so, NLU systems need a lexicon of the language, a software component called a parser for taking input data and building a data structure, grammar rules, and semantics theory.
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. NLP is one of the fast-growing research domains in AI, with applications that involve tasks including translation, summarization, text generation, and sentiment analysis. Businesses use NLP to power a growing number of applications, both internal — like detecting insurance fraud, determining customer sentiment, and optimizing aircraft maintenance — and customer-facing, like Google Translate. NLP attempts to analyze and understand the text of a given document, and NLU makes it possible to carry out a dialogue with a computer using natural language.
