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. 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. Understanding natural language is essential for enabling machines to communicate with people in a way that seems natural.

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. In NLU systems, this output is often generated by computer-generated speech or chat interfaces, which mimic human language patterns and demonstrate the system’s ability to process natural language input. With the help of natural language understanding (NLU) and machine learning, computers can automatically analyze data in seconds, saving businesses countless hours and resources when analyzing troves of customer feedback. Applications like virtual assistants, AI chatbots, and language-based interfaces will be made viable by closing the comprehension and communication gap between humans and machines.

NLU systems are used on a daily basis for answering customer calls and routing them to the appropriate department. IVR systems allow you to handle customer queries and complaints on a 24/7 basis without having to hire extra staff or pay your current staff for any overtime hours. NLU is necessary in data capture since the data being captured needs to be processed and understood by an algorithm to produce the necessary results. For instance, the word “bank” could mean a financial institution or the side of a river. Natural language includes slang and idioms, not in formal writing but common in everyday conversation.

Depending on your business, you may need to process data in a number of languages. Having support for many languages other than English will help you be more effective at meeting customer expectations. 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.

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. Without a strong relational model, the resulting response isn’t likely to be what the user intends to find.

Natural language generation is the process by which a computer program creates content based on human speech input. Agents can also help customers with more complex issues by using NLU technology combined with natural language generation tools to create personalized responses based on specific information about each customer’s situation. Natural language processing is the process of turning human-readable text into computer-readable data. It’s used in everything from online search engines to chatbots that can understand our questions and give us answers based on what we’ve typed. Business applications often rely on NLU to understand what people are saying in both spoken and written language.

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. The difference between natural language understanding and natural language generation is that the former deals with a computer’s ability to read comprehension, while the latter pertains to a machine’s writing capability. Companies can also use natural language understanding software in marketing campaigns by targeting specific groups of people with different messages based on what they’re already interested in. Natural language understanding (NLU) is a part of artificial intelligence (AI) focused on teaching computers how to understand and interpret human language as we use it naturally. Question answering is a subfield of NLP and speech recognition that uses NLU to help computers automatically understand natural language questions.

You’re falling behind if you’re not using NLU tools in your business’s customer experience initiatives. With today’s mountains of unstructured data generated daily, it is essential to utilize NLU-enabled technology. The technology can help you effectively communicate with consumers and save the energy, time, and money that would be expensed otherwise. NLP is about understanding and processing human language.NLU is about understanding human language.NLG is about generating human language. By default, virtual assistants tell you the weather for your current location, unless you specify a particular city.

Scope and context

Additionally, NLU systems can use machine learning algorithms to learn from past experience and improve their understanding of natural language. Natural language understanding is a field that involves the application of artificial intelligence techniques to understand human languages. Natural language understanding aims to achieve human-like communication with computers by creating a digital system that can recognize and respond appropriately to human speech. Two people may read or listen to the same passage and walk away with completely different interpretations. If humans struggle to develop perfectly aligned understanding of human language due to these congenital linguistic challenges, it stands to reason that machines will struggle when encountering this unstructured data. For instance, virtual assistants like Siri, Alexa, and Google Assistant use NLU to understand and respond to voice commands.

The NLU solutions and systems at Fast Data Science use advanced AI and ML techniques to extract, tag, and rate concepts which are relevant to customer experience analysis, business intelligence and insights, and much more. If people can have different interpretations of the same language due to specific congenital linguistic challenges, then you can bet machines will also struggle when they come across unstructured data. NLU technology can also help customer support agents gather information from customers and create personalized responses. 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. Furthermore, different languages have different grammatical structures, which could also pose challenges for NLU systems to interpret the content of the sentence correctly.

  • There are so many possible use-cases for NLU and NLP and as more advancements are made in this space, we will begin to see an increase of uses across all spaces.
  • Find out how to successfully integrate a conversational AI chatbot into your platform.

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. Manual ticketing is a tedious, inefficient process that often leads to delays, frustration, and miscommunication. This technology allows your system to understand the text within each ticket, effectively filtering and routing tasks to the appropriate expert or department. For example, it is difficult for call center employees to remain consistently positive with customers at all hours of the day or night.

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. Determining the sentiment behind a piece of text, whether it’s positive, negative, or neutral. This is often used in social media monitoring, customer feedback analysis, and product reviews.

We don’t really think much of it every time we speak but human language is fluid, seamless, complex and full of nuances. What’s interesting is that two people may read a passage and have completely different interpretations based on their own understanding, values, philosophies, mindset, etc. Natural language understanding software doesn’t just understand the meaning of the individual words within a sentence, it also understands what they mean when they are put together. This means that NLU-powered conversational interfaces can grasp the meaning behind speech and determine the objectives of the words we use.

Semantics alludes to a sentence’s intended meaning, while syntax refers to its grammatical structure. There are several benefits of natural language understanding for both humans and machines. Humans can communicate more effectively with systems that understand their language, and those machines can better respond to human needs. 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). 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.

Imagine how much cost reduction can be had in the form of shorter calls and improved customer feedback as well as satisfaction levels. Answering customer calls and directing them to the correct department or person is an everyday use case for NLUs. Implementing an IVR system allows businesses to handle customer queries 24/7 without hiring additional staff or paying for overtime hours. Find out how to successfully integrate a conversational AI chatbot into your platform. While progress is being made, a machine’s understanding in these areas is still less refined than a human’s. Ideally, your NLU solution should be able to create a highly developed interdependent network of data and responses, allowing insights to automatically trigger actions.

With an agent AI assistant, customer interactions are improved because agents have quick access to a docket of all past tickets and notes. This data-driven approach provides the information they need quickly, so they can quickly resolve issues – instead of searching multiple channels for answers. It understands the actual request and facilitates a speedy response from the right person or team (e.g., help desk, legal, sales).

Natural Language Understanding Examples

Latin, English, Spanish, and many other spoken languages are all languages that evolved naturally over time. Robotic process automation (RPA) is an exciting software-based technology which utilises bots to automate routine tasks within applications which are meant for employee use only. Many professional solutions in this category utilise NLP and NLU capabilities to quickly understand massive amounts of text in documents and applications. Data capture applications enable users to enter specific information on a web form using NLP matching instead of typing everything out manually on their keyboard. This makes it a lot quicker for users because there’s no longer a need to remember what each field is for or how to fill it up correctly with their keyboard.

There are 4.95 billion internet users globally, 4.62 billion social media users, and over two thirds of the world using mobile, and all of them will likely encounter and expect NLU-based responses. Consumers are accustomed to getting a sophisticated reply to their individual, unique input – 20% of Google searches are now done by voice, for example. Without using NLU tools in your business, you’re limiting the customer experience you can provide. Natural language understanding (NLU) is a branch of artificial intelligence (AI) that uses computer software to understand input in the form of sentences using text or speech. 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.

Natural language understanding can help speed up the document review process while ensuring accuracy.

The goal of a chatbot is to minimize the amount of time people need to spend interacting with computers and maximize the amount of time they spend doing other things. For instance, you are an online retailer with data about what your customers buy and when they buy them. For example, when a human reads a user’s question on Twitter and replies with an answer, or on a large scale, like when Google parses millions of documents to figure out what they’re about. 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. In this context, another term which is often used as a synonym is Natural Language Understanding (NLU).

The NLP market is predicted reach more than $43 billion in 2025, nearly 14 times more than it was in 2017. Millions of businesses already use NLU-based technology to analyze human input and gather actionable insights. Identifying their objective helps the software to understand what the goal of the interaction is. In this example, the NLU technology is able to surmise that the person wants to purchase tickets, and the most likely mode of travel is by airplane.

Additionally, NLU is used in text analysis, sentiment analysis, and machine translation. Natural language processing (NLP), a branch of artificial intelligence (AI), studies the relationship between computers and human language. It involves developing algorithms and models that enable robots to understand, interpret, and produce language akin to that of humans. 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.

Natural language understanding (NLU) uses the power of machine learning to convert speech to text and analyze its intent during any interaction. Before a computer can process unstructured text into a machine-readable format, first machines need to understand the peculiarities of the human language. 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.

Your NLU software takes a statistical sample of recorded calls and performs speech recognition after transcribing the calls to text via MT (machine translation). The NLU-based text analysis links specific speech patterns to both negative emotions and high effort levels. Natural language understanding gives us the ability to bridge the communicational gap between humans and computers. NLU empowers artificial intelligence to offer people assistance and has a wide range of applications. For example, customer support operations can be substantially improved by intelligent chatbots. Conversational interfaces, also known as chatbots, sit on the front end of a website in order for customers to interact with a business.

NLU enables computers to understand the sentiments expressed in a natural language used by humans, such as English, French or Mandarin, without the formalized syntax of computer languages. NLU allows computers to communicate with people in their own language, eliminating the need for a specialized computer language. It also helps in analyzing social media sentiment, enhancing customer service, and improving accessibility through voice-activated systems. In machine learning (ML) jargon, the series of steps taken are called data pre-processing. The idea is to break down the natural language text into smaller and more manageable chunks. These can then be analyzed by ML algorithms to find relations, dependencies, and context among various chunks.

Gain business intelligence and industry insights by quickly deciphering massive volumes of unstructured data. 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 Understanding (NLU) has become an essential part of many industries, including customer service, healthcare, finance, and retail.

An ideal natural language understanding or NLU solution should be built to utilise an extensive bank of data and analysis to recognise the entities and relationships between them. It should be able to easily understand even the most complex sentiment and extract motive, intent, effort, emotion, and intensity easily, and as a result, make the correct inferences and suggestions. You see, when you analyse data using NLU or natural language understanding software, you can find new, more practical, and more cost-effective ways to make business decisions – based on the data you just unlocked. To further grasp “what is natural language understanding”, we must briefly understand both NLP (natural language processing) and NLG (natural language generation). The core capability of NLU technology is to understand language in the same way humans do instead of relying on keywords to grasp concepts. As language recognition software, NLU algorithms can enhance the interaction between humans and organizations while also improving data gathering and analysis.

Due to the fluidity, complexity, and subtleties of human language, it’s often difficult for two people to listen or read the same piece of text and walk away with entirely aligned interpretations. In this step, the system looks at the relationships between sentences to determine the meaning of a text. This process focuses on how different sentences relate to each other and how they contribute to the overall meaning of a text.

Natural Language Generation (NLG) involves machines producing human-like language, generating coherent and contextually relevant text based on the given input or data. Using natural language understanding software for data analysis can open up new avenues for making informed business decisions. As an online shop, for example, you have information about the products and the times at which your customers purchase them. You may see trends in your customers’ behavior and make more informed decisions about what things to offer them in the future by using natural language understanding software.
