Guide to Natural Language Understanding NLU in 2024

What is NLU and How Is It Different from NLP?

Using predictive modeling algorithms, you can identify these speech patterns automatically in forthcoming calls and recommend a response from your customer service representatives as they are on the call to the customer. This reduces the cost to serve with shorter calls, and improves customer feedback. Speech recognition uses NLU techniques to let computers understand questions posed with natural language. NLU is used to give the users of the device a response in their natural language, instead of providing them a list of possible answers.

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). For example, entity analysis can identify specific entities mentioned by customers, such as product names or locations, to gain insights into what aspects of the company are most discussed. Sentiment analysis can help determine the overall attitude of customers towards the company, while content analysis can reveal common themes and topics mentioned in customer feedback. Trying to meet customers on an individual level is difficult when the scale is so vast. Rather than using human resource to provide a tailored experience, NLU software can capture, process and react to the large quantities of unstructured data that customers provide at scale.

IVR, or Interactive Voice Response, is a technology that lets inbound callers use pre-recorded messaging and options as well as routing strategies to send calls to a live operator. Let’s take an example of how you could lower call center costs and improve customer satisfaction using NLU-based technology. Natural Language Understanding (NLU) https://chat.openai.com/ is a field of computer science which analyzes what human language means, rather than simply what individual words say. GLUE and its superior SuperGLUE are the most widely used benchmarks to evaluate the performance of a model on a collection of tasks, instead of a single task in order to maintain a general view on the NLU performance.

AI technology has become fundamental in business, whether you realize it or not. Recommendations on Spotify or Netflix, auto-correct and auto-reply, virtual assistants, and automatic email categorization, to name just a few. Natural Language Understanding Applications are becoming increasingly important in the business world. NLUs require specialized skills in the fields of AI and machine learning and this can prevent development teams that lack the time and resources to add NLP capabilities to their applications. 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.

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. Natural Language Processing is a branch of artificial intelligence that uses machine learning algorithms to help computers understand natural human language. Your software can take a statistical sample of recorded calls and perform speech recognition after transcribing the calls to text using machine translation. The NLU-based text analysis can link specific speech patterns to negative emotions and high effort levels.

Natural Language Understanding: What It Is and How It Differs from NLP

These low-friction channels allow customers to quickly interact with your organization with little hassle. As a result, chatbots tend to produce higher customer satisfaction ratings. NLP is concerned with how computers are programmed to process language and facilitate “natural” back-and-forth communication between computers and humans.

By analyzing customer inquiries and detecting patterns, NLU-powered systems can suggest relevant solutions and offer personalized recommendations, making the customer feel heard and valued. In conclusion, for NLU to be effective, it must address the numerous challenges posed by natural language inputs. Addressing lexical, syntax, and referential ambiguities, and understanding the unique features of different languages, are necessary for efficient NLU systems. Being able to rapidly process unstructured data gives you the ability to respond in an agile, customer-first way. Make sure your NLU solution is able to parse, process and develop insights at scale and at speed.

This gives customers the choice to use their natural language to navigate menus and collect information, which is faster, easier, and creates a better experience. You can foun additiona information about ai customer service and artificial intelligence and NLP. Simply put, using previously gathered and analyzed information, computer programs are able to generate conclusions. For example, in medicine, machines can infer a diagnosis based on previous diagnoses using IF-THEN deduction rules.

False patient reviews can hurt both businesses and those seeking treatment. Sentiment analysis, thus NLU, can locate fraudulent reviews by identifying the text’s emotional character. For instance, inflated statements and an excessive amount of punctuation may indicate a fraudulent review.

Natural Language Understanding Examples

NLP and NLU, two subfields of artificial intelligence (AI), facilitate understanding and responding to human language. Both of these technologies are beneficial to companies in various industries. Voice assistants and virtual assistants have several common features, such as the ability to set reminders, play music, and provide news and weather updates. They also offer personalized recommendations based on user behavior and preferences, making them an essential part of the modern home and workplace. As NLU technology continues to advance, voice assistants and virtual assistants are likely to become even more capable and integrated into our daily lives. Two key concepts in natural language processing are intent recognition and entity recognition.

As its name suggests, natural language processing deals with the process of getting computers to understand human language and respond in a way that is natural for humans. Natural language understanding (NLU) technology plays a crucial role in customer experience management. By allowing machines to comprehend human language, NLU enables chatbots and virtual assistants to interact with customers more naturally, providing a seamless and satisfying experience. However, true understanding of natural language is challenging due to the complexity and nuance of human communication. Machine learning approaches, such as deep learning and statistical models, can help overcome these obstacles by analyzing large datasets and finding patterns that aid in interpretation and understanding. Overall, text analysis and sentiment analysis are critical tools utilized in NLU to accurately interpret and understand human language.

He led technology strategy and procurement of a telco while reporting to the CEO. He has also led commercial growth of deep tech company Hypatos that reached a 7 digit annual recurring revenue and a 9 digit valuation from 0 within 2 years. Cem’s work in Hypatos was covered by leading technology publications like TechCrunch and Business Insider. He graduated from Bogazici University as a computer engineer and holds an MBA from Columbia Business School. On average, an agent spends only a quarter of their time during a call interacting with the customer.

Natural language understanding (NLU) is a branch of natural language processing that deals with extracting meaning from text and speech. To do this, NLU uses semantic and syntactic analysis to determine the intended purpose of a sentence. Semantics alludes to a sentence’s intended meaning, while syntax refers to its grammatical structure. In other words, NLU is Artificial Intelligence that uses computer software to interpret text and any type of unstructured data.

As a result, they do not require both excellent NLU skills and intent recognition. 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. NLP links Paris to France, Arkansas, and Paris Hilton, as well as France to France and the French national football team.

This targeted content can be used to improve customer engagement and loyalty. By 2025, the NLP market is expected to surpass $43 billion–a 14-fold increase from 2017. Businesses worldwide are already relying on NLU technology to make sense of human input and gather insights toward improved decision-making. In this step, the system looks at the relationships between sentences to determine the meaning of a text.

NLU goes a step further by understanding the context and meaning behind the text data, allowing for more advanced applications such as chatbots or virtual assistants. The NLU field is dedicated to developing strategies and techniques for understanding context in individual records and at scale. NLU systems Chat PG empower analysts to distill large volumes of unstructured text into coherent groups without reading them one by one. This allows us to resolve tasks such as content analysis, topic modeling, machine translation, and question answering at volumes that would be impossible to achieve using human effort alone.

Common devices and platforms where NLU is used to communicate with users include smartphones, home assistants, and chatbots. These systems can perform tasks such as scheduling appointments, answering customer support inquiries, or providing helpful information in a conversational format. Natural Language Understanding is a crucial component of modern-day technology, enabling machines to understand human language and communicate effectively with users. Natural language processing (NLP) is a field of computer science, artificial intelligence, and linguistics concerned with the interactions between machines and human (natural) languages.

IVR makes a great impact on customer support teams that utilize phone systems as a channel since it can assist in mitigating support needs for agents. There are many downstream NLP tasks relevant to NLU, such as named entity recognition, part-of-speech tagging, and semantic analysis. These tasks help NLU models identify key components of a sentence, including the entities, verbs, and relationships between them.

Using NLU, voice assistants can recognize spoken instructions and take action based on those instructions. For example, a user might say, “Hey Siri, schedule a meeting for 2 pm with John Smith.” The voice assistant would use NLU to understand nlu definition the command and then access the user’s calendar to schedule the meeting. Similarly, a user could say, “Alexa, send an email to my boss.” Alexa would use NLU to understand the request and then compose and send the email on the user’s behalf.

That leaves three-quarters of the conversation for research–which is often manual and tedious. But when you use an integrated system that ‘listens,’ it can share what it learns automatically- making your job much easier. In other words, when a customer asks a question, it will be the automated system that provides the answer, and all the agent has to do is choose which one is best. Also, NLU can generate targeted content for customers based on their preferences and interests.

In NLU, machine learning models improve over time as they learn to recognize syntax, context, language patterns, unique definitions, sentiment, and intent. In today’s age of digital communication, computers have become a vital component of our lives. As a result, understanding human language, or Natural Language Understanding (NLU), has gained immense importance. NLU is a part of artificial intelligence that allows computers to understand, interpret, and respond to human language. NLU helps computers comprehend the meaning of words, phrases, and the context in which they are used.

Supervised methods of word-sense disambiguation include the user of support vector machines and memory-based learning. However, most word sense disambiguation models are semi-supervised models that employ both labeled and unlabeled data. Natural language understanding (NLU) is a technical concept within the larger topic of natural language processing.

Taking action and forming a response

By unlocking the insights in unstructured text and driving intelligent actions through natural language understanding, NLU can help businesses deliver better customer experiences and drive efficiency gains. Natural language understanding (NLU) is an artificial intelligence-powered technology that allows machines to understand human language. The technology sorts through mispronunciations, lousy grammar, misspelled words, and sentences to determine a person’s actual intent. To do this, NLU has to analyze words, syntax, and the context and intent behind the words. 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.

Both NLP and NLU aim to make sense of unstructured data, but there is a difference between the two. By considering clients’ habits and hobbies, nowadays chatbots recommend holiday packages to customers (see Figure 8). Since it is not a standardized conversation, NLU capabilities are required.

NLU systems use these three steps to analyze a text and extract its meaning. Additionally, NLU systems can use machine learning algorithms to learn from past experience and improve their understanding of natural language. 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. Natural language output, on the other hand, is the process by which the machine presents information or communicates with the user in a natural language format. This may include text, spoken words, or other audio-visual cues such as gestures or images.

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. Most of the time financial consultants try to understand what customers were looking for since customers do not use the technical lingo of investment. Since customers’ input is not standardized, chatbots need powerful NLU capabilities to understand customers. When an unfortunate incident occurs, customers file a claim to seek compensation.

NLU is the process responsible for translating natural, human words into a format that a computer can interpret. Essentially, before a computer can process language data, it must understand the data. In fact, according to Accenture, 91% of consumers say that relevant offers and recommendations are key factors in their decision to shop with a certain company. NLU software doesn’t have the same limitations humans have when processing large amounts of data. It can easily capture, process, and react to these unstructured, customer-generated data sets.

On the other hand, entity recognition involves identifying relevant pieces of information within a language, such as the names of people, organizations, locations, and numeric entities. A sophisticated NLU solution should be able to rely on a comprehensive bank of data and analysis to help it recognize entities and the relationships between them. It should be able  to understand complex sentiment and pull out emotion, effort, intent, motive, intensity, and more easily, and make inferences and suggestions as a result. It should also have training and continuous learning capabilities built in.

For example, the chatbot could say, “I’m sorry to hear you’re struggling with our service. I would be happy to help you resolve the issue.” This creates a conversation that feels very human but doesn’t have the common limitations humans do. Although natural language understanding (NLU), natural language processing (NLP), and natural language generation (NLG) are similar topics, they are each distinct.

In addition, referential ambiguity, which occurs when a word could refer to multiple entities, makes it difficult for NLU systems to understand the intended meaning of a sentence. This is particularly important, given the scale of unstructured text that is generated on an everyday basis. NLU-enabled technology will be needed to get the most out of this information, and save you time, money and energy to respond in a way that consumers will appreciate. Using our example, an unsophisticated software tool could respond by showing data for all types of transport, and display timetable information rather than links for purchasing tickets. Without being able to infer intent accurately, the user won’t get the response they’re looking for. Natural Language Understanding is a subset area of research and development that relies on foundational elements from Natural Language Processing (NLP) systems, which map out linguistic elements and structures.

According to Zendesk, tech companies receive more than 2,600 customer support inquiries per month. Using NLU technology, you can sort unstructured data (email, social media, live chat, etc.) by topic, sentiment, and urgency (among others). These tickets can then be routed directly to the relevant agent and prioritized. Natural Language Understanding is a big component of IVR since interactive voice response is taking in someone’s words and processing it to understand the intent and sentiment behind the caller’s needs.
