NLU vs NLP in 2024: Main Differences & Use Cases Comparison

difference between nlp and nlu

People can express the same idea in different ways, but sometimes they make mistakes when speaking or writing. They could use the wrong words, write sentences that don’t make sense, or misspell or mispronounce words. NLP can study language and speech to do many things, but it can’t always understand what someone https://chat.openai.com/ intends to say. NLU enables computers to understand what someone meant, even if they didn’t say it perfectly. 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.

While natural language understanding focuses on computer reading comprehension, natural language generation enables computers to write. NLG is the process of producing a human language text response based on some data input. This text can also be converted into a speech format through text-to-speech services. 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.

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. NLU allows computer applications to infer intent from language even when the written or spoken language is flawed. Sometimes you may have too many lines of text data, and you have time scarcity to handle all that data.

This enables machines to produce more accurate and appropriate responses during interactions. As humans, we can identify such underlying similarities almost effortlessly and respond accordingly. But this is a problem for machines—any algorithm will need the input to be in a set format, and these three sentences vary in their structure and format.

Correlation Between NLP and NLU

This process enables the extraction of valuable information from the text and allows for a more in-depth analysis of linguistic patterns. For example, NLP can identify noun phrases, verb phrases, and other grammatical structures in sentences. Have you ever wondered how Alexa, ChatGPT, or a customer care chatbot can understand your spoken or written comment and respond appropriately?

It is also applied in text classification, document matching, machine translation, named entity recognition, search autocorrect and autocomplete, etc. NLP uses computational linguistics, computational neuroscience, and deep learning technologies to perform these functions. NLU goes beyond the basic processing of language and is meant to comprehend and extract meaning from text or speech. As a result, NLU  deals with more advanced tasks like semantic analysis, coreference resolution, and intent recognition. 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.

This algorithmic approach uses statistical analysis of ‘training’ documents to establish rules and build its knowledge base. However, because language and grammar rules can be complex and contradictory, this algorithmic approach can sometimes produce incorrect results without human oversight and correction. Natural Language Processing, or NLP, involves the processing of human language by a computer program to determine what its meaning is. As already seen in the above information, NLU is a part of NLP and thus offers similar benefits which solve several problems. In other words, NLU helps NLP to achieve more efficient results by giving a human-like experience through machines.

Help your business get on the right track to analyze and infuse your data at scale for AI. Natural language processing and its subsets have numerous practical applications within today’s world, like healthcare diagnoses or online customer service. Natural Language Processing allows an IVR solution to understand callers, detect emotion and identify keywords in order to fully capture their intent and respond accordingly. Ultimately, the goal is to allow the Interactive Voice Response system to handle more queries, and deal with them more effectively with the minimum of human interaction to reduce handling times. Together with NLG, they will be able to easily help in dealing and interacting with human customers and carry out various other natural language-related operations in companies and businesses.

One of the primary goals of NLU is to teach machines how to interpret and understand language inputted by humans. NLU leverages AI algorithms to recognize attributes of language such as sentiment, semantics, context, and intent. For example, the questions “what’s the Chat PG weather like outside?” and “how’s the weather?” are both asking the same thing. 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 techniques enable systems to grasp the nuances, references, and connections within the text or speech resolve ambiguities and incorporate external knowledge for a comprehensive understanding. NLP utilizes statistical models and rule-enabled systems to handle and juggle with language. Handcrafted rules are designed by experts and specify how certain language elements should be treated, such as grammar rules or syntactic structures. NLP and NLU are significant terms for designing a machine that can easily understand the human language, whether it contains some common flaws.

As a result, they do not require both excellent NLU skills and intent recognition. Thus, it helps businesses to understand customer needs and offer them personalized products. You can foun additiona information about ai customer service and artificial intelligence and NLP. Data pre-processing aims to divide the natural language content into smaller, simpler sections. ML algorithms can then examine these to discover relationships, connections, and context between these smaller sections.

It provides the ability to give instructions to machines in a more easy and efficient manner. Expert.ai Answers makes every step of the support process easier, faster and less expensive both for the customer and the support staff. DST is essential at this stage of the dialogue system and is responsible for multi-turn conversations. Then, a dialogue policy determines what next step the dialogue system makes based on the current state.

Use Cases for NLP, NLU, and NLG

Natural Language Understanding is a vital part of the NLP process, which allows a conversational AI platform to extract intent from human input and formulate a response, whether from a scripted range or an AI-driven process. However, when it comes to handling the requests of human customers, it becomes challenging. This is due to the fact that with so many customers from all over the world, there is also a diverse range of languages.

NLP and NLU, two subfields of artificial intelligence (AI), facilitate understanding and responding to human language. Though looking very similar and seemingly performing the same function, NLP and NLU serve different purposes within the field of human language processing and understanding. Natural Language Processing focuses on the interaction between computers and human language.

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. By reviewing comments with negative sentiment, companies are able to identify and address potential problem areas within their products or services more quickly. The fascinating world of human communication is built on the intricate relationship between syntax and semantics. While syntax focuses on the rules governing language structure, semantics delves into the meaning behind words and sentences. In the realm of artificial intelligence, NLU and NLP bring these concepts to life.

A test developed by Alan Turing in the 1950s, which pits humans against the machine. All these sentences have the same underlying question, which is to enquire about today’s weather forecast. Natural languages are different from formal or constructed languages, which have a different origin and development path.

As we continue to advance in the realms of artificial intelligence and machine learning, the importance of NLP and NLU will only grow. However, navigating the complexities of natural language processing and natural language understanding can be a challenging task. This is where Simform’s expertise in AI and machine learning development services can help you overcome those challenges and leverage cutting-edge language processing technologies. 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. In other words, NLU is Artificial Intelligence that uses computer software to interpret text and any type of unstructured data. NLU can digest a text, translate it into computer language and produce an output in a language that humans can understand.

And if the assistant doesn’t understand what the user means, it won’t respond appropriately or at all in some cases. 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 processes flow through a continuous feedback loop with machine learning to improve the computer’s artificial intelligence algorithms. Rather than relying on keyword-sensitive scripts, NLU creates unique responses based on previous interactions. It aims to highlight appropriate information, guess context, and take actionable insights from the given text or speech data.

This allows us to find the best way to engage with users on a case-by-case basis. However, these are products, not services, and are currently marketed, not to replace writers, but to assist, provide inspiration, and enable the creation of multilingual copy. Here are some of the best NLP papers from the Association for Computational Linguistics 2022 conference. Natural Language Processing (NLP), Natural Language Understanding (NLU), and Natural Language Generation (NLG) all fall under the umbrella of artificial intelligence (AI).

This response is converted into understandable human language using natural language generation. Natural Language Processing, a fascinating subfield of computer science and artificial intelligence, enables computers to understand and interpret human language as effortlessly as you decipher the words in this sentence. NLP considers how computers can process and analyze vast amounts of natural language data and can understand and communicate with humans. The latest boom has been the popularity of representation learning and deep neural network style machine learning methods since 2010. These methods have been shown to achieve state-of-the-art results for many natural language tasks.

Finding one right for you involves knowing a little about their work and what they can do. To help you on the way, here are seven chatbot use cases to improve customer experience. 86% of consumers say good customer service can take them from first-time buyers to brand advocates. While excellent customer service is an essential focus of any successful brand, forward-thinking companies are forming customer-focused multidisciplinary teams to help create exceptional customer experiences.

CEO of NeuralSpace, told SlatorPod of his hopes in coming years for voice-to-voice live translation, the ability to get high-performance NLP in tiny devices (e.g., car computers), and auto-NLP. Ecommerce websites rely heavily on sentiment analysis of the reviews and feedback from the users—was a review positive, negative, or neutral? Here, they need to know what was said and they also need to understand what was meant. Gone are the days when chatbots could only produce programmed and rule-based interactions with their users.

NLP links Paris to France, Arkansas, and Paris Hilton, as well as France to France and the French national football team. 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. NLU relies on NLP’s syntactic analysis to detect and extract the structure and context of the language, which is then used to derive meaning and understand intent. Processing techniques serve as the groundwork upon which understanding techniques are developed and applied.

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. NLU converts input text or speech into structured data and helps extract facts from this input data. Once a customer’s intent is understood, machine learning determines an appropriate response.

NLP and NLU have unique strengths and applications as mentioned above, but their true power lies in their combined use. Integrating both technologies allows AI systems to process and understand natural language more accurately. Before booking a hotel, customers want to learn more about the potential accommodations. 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 an eye on surface-level processing, NLP prioritizes tasks like sentence structure, word order, and basic syntactic analysis, but it does not delve into comprehension of deeper semantic layers of the text or speech. 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. 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.

This allows the system to provide a structured, relevant response based on the intents and entities provided in the query. That might involve sending the user directly to a product page or initiating a set of production option pages before sending a direct link to purchase the item. When it comes to relations between these techs, NLU is perceived as an extension of NLP that provides the foundational techniques and methodologies for language processing. NLU builds upon these foundations and performs deep analysis to understand the meaning and intent behind the language. NLP primarily works on the syntactic and structural aspects of language to understand the grammatical structure of sentences and texts. With the surface-level inspection in focus, these tasks enable the machine to discern the basic framework and elements of language for further processing and structural analysis.

It involves the development of algorithms and techniques to enable computers to comprehend, analyze, and generate textual or speech input in a meaningful and useful way. The tech aims at bridging the gap between human interaction and computer understanding. 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. NLG is another subcategory of NLP which builds sentences and creates text responses understood by humans. 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.

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. NLG also encompasses text summarization capabilities that generate summaries from in-put documents while maintaining the integrity of the information. Extractive summarization is the AI innovation powering Key Point Analysis used in That’s Debatable.

Just think of all the online text you consume daily, social media, news, research, product websites, and more. But before any of this natural language processing can happen, the text needs to be standardized. Explore some of the latest NLP research at IBM or take a look at some of IBM’s product offerings, like Watson Natural Language Understanding. Its text analytics service offers insight into categories, concepts, entities, keywords, relationships, sentiment, and syntax from your textual data to help you respond to user needs quickly and efficiently.

Each plays a unique role at various stages of a conversation between a human and a machine. Although chatbots and conversational AI are sometimes used interchangeably, they aren’t the same thing. Today we’ll review the difference between chatbots and conversational AI and which option is better for your business.

As we summarize everything written under this NLU vs. NLP article, it can be concluded that both terms, NLP and NLU, are interconnected and extremely important for enhancing natural language in artificial intelligence. Machines programmed with NGL help in generating new texts in addition to the already processed natural language. They are so advanced and innovative that they appear as if a real human being has written them. With more progress in technology made in recent years, there has also emerged a new branch of artificial intelligence, other than NLP and NLU. It is another subfield of NLP called NLG, or Natural Language Generation, which has received a lot of prominence and recognition in recent times. We’ve seen that NLP primarily deals with analyzing the language’s structure and form, focusing on aspects like grammar, word formation, and punctuation.

And if we decide to code rules for each and every combination of words in any natural language to help a machine understand, then things will get very complicated very quickly. While natural language processing (NLP), natural language understanding (NLU), and natural language generation (NLG) are all related topics, they are distinct ones. Given how they intersect, they are commonly confused within conversation, but in this post, we’ll define each term individually and summarize their differences to clarify any ambiguities. Natural language processing primarily focuses on syntax, which deals with the structure and organization of language. NLP techniques such as tokenization, stemming, and parsing are employed to break down sentences into their constituent parts, like words and phrases.

With the advent of ChatGPT, it feels like we’re venturing into a whole new world. Everyone can ask questions and give commands to what is perceived as an “omniscient” chatbot. Big Tech got shaken up with Google introducing their LaMDA-based “Bard” and Bing Search incorporating GPT-4 with Bing Chat.

In this context, another term which is often used as a synonym is Natural Language Understanding (NLU).

The customer journey, from acquisition to retention, is filled with potential incremental drop-offs at every touchpoint. A confusing experience here, an ill-timed communication there, and your conversion rate is suddenly plummeting. 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.

For those interested, here is our benchmarking on the top sentiment analysis tools in the market. At Kommunicate, we envision a world-beating customer support solution to empower the new era of customer support. We would love to have you on board to have a first-hand experience of Kommunicate. NLP is a branch of AI that allows more natural human-to-computer communication by linking human and machine language. Bharat Saxena has over 15 years of experience in software product development, and has worked in various stages, from coding to managing a product. His current active areas of research are conversational AI and algorithmic bias in AI.

Common tasks include parsing, speech recognition, part-of-speech tagging, and information extraction. It uses neural networks and advanced algorithms to learn from large amounts of data, allowing systems to comprehend and interpret language more effectively. NLU often involves incorporating external knowledge sources, such as ontologies, knowledge graphs, or commonsense databases, to enhance understanding. The technology also utilizes semantic role labeling (SRL) to identify the roles and relationships of words or phrases in a sentence with respect to a specific predicate.

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. Natural language processing is generally more suitable for tasks involving data extraction, text summarization, and machine translation, among others.

At this point, there comes the requirement of something called ‘natural language’ in the world of artificial intelligence. The algorithms we mentioned earlier contribute to the functioning of natural language generation, enabling it to create coherent and contextually relevant text or speech. However, the full potential of NLP cannot be realized without the support of NLU.

For example, for HR specialists seeking to hire Node.js developers, the tech can help optimize the search process to narrow down the choice to candidates with appropriate skills and programming language knowledge. Technology continues to advance and contribute to various domains, enhancing human-computer interaction and enabling machines to comprehend and process language inputs more effectively. To pass the test, a human evaluator will interact with a machine and another human at the same time, each in a different room. If the evaluator is not able to reliably tell the difference between the response generated by the machine and the other human, then the machine passes the test and is considered to be exhibiting “intelligent” behavior. Latin, English, Spanish, and many other spoken languages are all languages that evolved naturally over time. 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.

We discussed this with Arman van Lieshout, Product Manager at CM.com, for our Conversational AI solution. With NLP integrated into an IVR, it becomes a voice bot solution as opposed to a strict, scripted IVR solution. Voice bots allow direct, contextual interaction with the computer software via NLP technology, allowing the Voice bot to understand and respond with a relevant answer to a non-scripted question. It allows callers to interact with an automated assistant without the need to speak to a human and resolve issues via a series of predetermined automated questions and responses.

Sometimes people know what they are looking for but do not know the exact name of the good. 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 difference between nlp and nlu Figure 6). 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. In machine learning (ML) jargon, the series of steps taken are called data pre-processing.

This component responds to the user in the same language in which the input was provided say the user asks something in English then the system will return the output in English. Being able to formulate meaningful answers in response to users’ questions is the domain of expert.ai Answers. This expert.ai solution supports businesses through customer experience management and automated personal customer assistants. By employing expert.ai Answers, businesses provide meticulous, relevant answers to customer requests on first contact. Instead they are different parts of the same process of natural language elaboration.

Still, it can also enhance several existing technologies, often without a complete ‘rip and replace’ of legacy systems. NLU is particularly effective with homonyms – words spelled the same but with different meanings, such as ‘bank’ – meaning a financial institution – and ‘bank’ – representing a river bank, for example. Human speech is complex, so the ability to interpret context from a string of words is hugely important.

And so, understanding NLU is the second step toward enhancing the accuracy and efficiency of your speech recognition and language translation systems. As a seasoned technologist, Adarsh brings over 14+ years of experience in software development, artificial intelligence, and machine learning to his role. His expertise in building scalable and robust tech solutions has been instrumental in the company’s growth and success. By way of contrast, NLU targets deep semantic understanding and multi-faceted analysis to comprehend the meaning, aim, and textual environment.

This integration of language technologies is driving innovation and improving user experiences across various industries. Together, NLU and natural language generation enable NLP to function effectively, providing a comprehensive language processing solution. NLU analyzes data using algorithms to determine its meaning and reduce human speech into a structured ontology consisting of semantic and pragmatic definitions. Structured data is important for efficiently storing, organizing, and analyzing information. NLU focuses on understanding human language, while NLP covers the interaction between machines and natural language. With FAQ chatbots, businesses can reduce their customer care workload (see Figure 5).
