What’s the Difference Between NLP, NLU, and NLG?

Basically, the library gives a computer or system a set of rules and definitions for natural language as a foundation. Whether it’s simple chatbots or sophisticated AI assistants, NLP is an integral part of the conversational app building process. And the difference between NLP and NLU is important to remember when building a conversational app because it impacts how well the app interprets what was said and meant by users.

Companies receive thousands of requests for support every day, so NLU algorithms are useful in prioritizing tickets and enabling support agents to handle them in more efficient ways. Natural Language Understanding (NLU) is a versatile technology with various applications across various industries. This section will explore how NLU is leveraged to enhance processes, improve user experiences, and extract valuable insights from human language.

How does natural language understanding work?

As technology evolves, NLU systems are increasingly required to process and interpret multiple modalities, including text, speech, images, and videos. Developing NLU systems that can effectively understand and integrate information from different modalities presents a complex technical challenge. Consider the word “bank,” which can refer to a financial institution or the edge of a river. NLU systems must rely on context cues to determine the intended meaning in such instances. Similarly, syntactic ambiguity, such as sentences like “I saw the man with the telescope,” presents additional complexity. As we explore Natural Language Understanding, we will dive deeper into how NLU works, its applications across various domains, the challenges it faces, and its promising future.

Chatbots are necessary for customers who want to avoid long wait times on the phone. With NLU (Natural Language Understanding), chatbots can become more conversational and evolve from basic commands and keyword recognition. With the advent of voice-controlled technologies like Google Home, consumers are now accustomed to getting unique replies to their individual queries; for example, one-fifth of all Google searches are voice-based.

What is Natural Language Understanding (NLU)?

This offers a great opportunity for companies to capture strategic information such as preferences, opinions, buying habits, or sentiments. Companies can utilize this information to identify operational risks, and derive actionable insights. 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.

There are various semantic theories used to interpret language, like stochastic semantic analysis or naive semantics. In other words, it fits natural language (sometimes referred to as unstructured text) into a structure that an application can act on. Systems will be trained to identify and respond to human emotions expressed in text and speech. This development will have far-reaching applications in mental health support, customer service, and user sentiment analysis. Sentiment analysis will evolve to encompass a broader spectrum of emotions, recognizing subtle nuances in emotional expression.

What is natural language processing?

And so, understanding NLU is the second step toward enhancing the accuracy and efficiency of your speech recognition and language translation systems. Integrating NLP and NLU with other AI domains, such as machine learning and computer vision, opens doors for advanced language translation, text summarization, and question-answering systems. The algorithms utilized in NLG play a vital role in ensuring the generation of coherent and meaningful language.

In this step, the system extracts meaning from a text by looking at the words used and how they are used. For example, the term “bank” can have different meanings depending on the context in which it is used. If someone says they are going to the “bank,” they could be going to a financial institution or to the edge of a river.

Improved Product Development

It reveals public opinion, customer satisfaction, and sentiment toward products, services, or issues. NLP models can determine text sentiment—positive, negative, or neutral—using several methods. This analysis helps analyze public opinion, client feedback, social media sentiments, and other textual communication. For instance, the address of the home a customer wants to cover has an impact on the underwriting process since it has a relationship with burglary risk. NLP-driven machines can automatically extract data from questionnaire forms, and risk can be calculated seamlessly.

Natural language understanding can also detect inconsistencies between the sender’s email address and the content of the message that could indicate a phishing attack. By detecting these anomalies, NLU can help protect users from malicious phishing attempts. Natural language understanding (NLU) can help improve the accuracy and efficiency of cybersecurity systems by automatically recognizing patterns in languages, such as slang or dialects, to categorize potential threats. Natural Language Understanding enables machines to understand a set of text by working to understand the language of the text. 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.

We can expect over the next few years for NLU to become even more powerful and more integrated into software. It can identify spelling and grammatical errors and interpret the intended message despite the mistakes. This can have a profound impact on a chatbot’s ability to carry on a successful conversation with a user. From categorizing text, gathering news and archiving individual pieces of text to analyzing content, it’s all possible with NLU. Real-world examples of NLU include small tasks like issuing short commands based on text comprehension to some small degree like redirecting an email to the right receiver based on basic syntax and decently sized lexicon. AI technology has become fundamental in business, whether you realize it or not.

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. Accenture reports that 91% of consumers say they are more likely to shop with companies that provide offers and recommendations that are relevant to them specifically. This is particularly important, given the scale of unstructured text that is generated on an everyday basis.

How NLP and NLU Stack Up

With the general advancement of linguistics, chatbots can be deployed to discern not just intents and meanings, but also to better understand sentiments, sarcasm, and even tone of voice. 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. 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.

• It is the technology that is used by machines to understand, analyze, manipulate, and interpret human languages.
• This can help companies better understand customer needs and provide tailored services and products.
• Unlike traditional language processing, which deals with syntax and structure, NLU dives deeper, focusing on the semantics and intent behind the words and phrases.
• In terms of business value, automating this process incorrectly without sufficient natural language understanding (NLU) could be disastrous.

An example of NLU in action is a virtual assistant understanding and responding to a user’s spoken request, such as providing weather information or setting a reminder. The collaboration between Natural Language Processing (NLP) and Natural Language Understanding (NLU) is a powerful force in the realm of language processing and artificial intelligence. By working together, NLP and NLU enhance each other’s capabilities, leading to more advanced and comprehensive language-based solutions.

As a result, NLU systems may occasionally misinterpret the intended meaning, leading to inaccurate analyses. Several intricate and multifaceted challenges persist in the ever-evolving realm of Natural Language Understanding (NLU), underscoring the complexities inherent to the field. These challenges testify to the intricate nature of human language and the ongoing endeavours required to advance NLU systems.

Just like learning to read where you first learn the alphabet, then sounds, and eventually words, the transcription of speech has evolved over time with technology. NLU is an algorithm that is trained to categorize information ‘inputs’ according to ‘semantic data classes’. The model finalized using neural networks is capable of determining whether X belongs to class Y, class Z, or any other class. Customer support agents can leverage NLU technology to gather information from customers while they’re on the phone without having to type out each question individually. Natural language generation is the process of turning computer-readable data into human-readable text. SHRDLU could understand simple English sentences in a restricted world of children’s blocks to direct a robotic arm to move items.
