NLP vs NLU: Whats the Difference? by Lola.com

Overall, natural language understanding is a complex field that continues to evolve with the help of machine learning and deep learning technologies. It plays an important role in customer service and virtual assistants, allowing computers to understand text in the same way humans do. 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. 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.

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. This targeted content can be used to improve customer engagement and loyalty.

Popular abbreviations of NLU:

Each plays a unique role at various stages of a conversation between a human and a machine. 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. Finally, the NLG gives a response based on the semantic frame.Now that we’ve seen how a typical dialogue system works, let’s clearly understand NLP, NLU, and NLG in detail.

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. 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 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. 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.

Get Started with Natural Language Understanding in AI

Natural language understanding is a branch of AI that understands sentences using text or speech. NLU allows machines to understand human interaction by using algorithms to reduce human speech into structured definitions and concepts for understanding relationships. If a developer wants to build a simple chatbot that produces a series of programmed responses, they could use NLP along with a few machine learning techniques. However, if a developer wants to build an intelligent contextual assistant capable of having sophisticated natural-sounding conversations with users, they would need NLU. NLU is the component that allows the contextual assistant to understand the intent of each utterance by a user. Without it, the assistant won’t be able to understand what a user means throughout a conversation.

Tools such as Algolia Answers allow for natural language interactions to quickly find existing content and reduce the amount of time journalists need in order to file stories. Readers can also benefit from NLU-driven content access that helps them draw connections across a range of sources and uncover answers to very specific questions in seconds. NLU can greatly help journalists and publishers extract answers to complex questions from deep within content using natural language interaction with content archives. Akkio uses its proprietary Neural Architecture Search (NAS) algorithm to automatically generate the most efficient architectures for NLU models.

Not only does this save customer support teams hundreds of hours,it also helps them prioritize urgent tickets. Using complex algorithms that rely on linguistic rules and AI machine training, Google Translate, Microsoft Translator, and Facebook Translation have become leaders in the field of “generic” language translation. It can be used to help customers better understand the products and services that they’re interested in, or it can be used to help businesses better understand their customers’ needs. In our research, we’ve found that more than 60% of consumers think that businesses need to care more about them, and would buy more if they felt the company cared. Part of this care is not only being able to adequately meet expectations for customer experience, but to provide a personalized experience.

The system will collect all intents from all ancestors to the current state, to choose from. As you can see, the entity of the intent can be accessed through the “it” variable. Of course, it is also possible to mix wildcard elements with entities (e.g., such as the built-in entity PersonName for “who”, or Color in a clothes store scenario).

The neural symbolic approach combines these two types of AI to create a system that can reason about human language. The neural part of the system is used to understand the meaning of words and phrases, while the symbolic part is used to reason about the relationships between them. If you’re looking for ways to understand your customers better, NLU is a great place to start. You can learn about their needs, wants, and pain points by analyzing their language. NLU is becoming a powerful source of voice technology that uses brilliant metrics to drill down vital information to improve your products and services.

In addition, the meta-learner leverages knowledge from high-resource source domains then enables the adaptation of low-data target domains within a few steps of gradient updating. For task-oriented dialogue systems, meta-learning also achieves a rapid adaptation of novel insinuations. Dialogue systems have been extensively implemented in various communication systems. However, the persona extraction from a few sentences of real-person conversation remains deficient.

As language recognition software, NLU algorithms can enhance the interaction between humans and organizations while also improving data gathering and analysis. 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. Natural language understanding implements algorithms that analyze human speech and break it down into semantic and pragmatic definitions. NLU technology aims to capture the intent behind communication and identify entities, such as people or numeric values, mentioned during speech.

As a result, NLU systems may occasionally misinterpret the intended meaning, leading to inaccurate analyses. Simply put, you can think of ASR as a speech recognition software that lets someone make a voice request. The transcription uses algorithms called Automatic Speech Recognition (ASR), which generates a written version of the conversation in real time.
