You’ll probably use Alexa or Siri to make the process smoother and save time.
Even website owners understand the value of this important feature and incorporate chatbots into their websites. They quickly provide answers to customer queries, give them recommendations, and do much more.
But how is it related to NLP and NLU?
The entire system behind it stands on these two things. NLP and NLU are technologies that have made virtual communication fast and efficient. These are two prominent subsets of artificial intelligence. These smart-systems analyze, process, and convert input into understandable human language.
But here’s one mistake people often make.
It is believing that NLP and NLU are the same. But that’s not true.
In this article, we’ll discuss how NLP and NLU are different from each other. Understanding this lets you choose the ideal AI solution for your automation needs.
What Is NLP?
NLP is an abbreviation of Natural Language Processing. It’s a branch of artificial intelligence where the primary focus is on the interaction between computers and humans with the help of natural language.
Here’s a glimpse of how this process goes.
Development of algorithms → Models are made → Enables computers to under → They easily interpret → Generate human-like language.
It acts as a bridge that closes the gap between human interaction and computer understanding.
Key Components Of NLP
Here are some of the key components of NLP. These are important in ensuring you get the best results using this technology.
- Tokenization: Breaking down text into smaller units, such as words or phrases (tokens). It enables analysis at the word or subword level, facilitating further processing.
- Named Entity Recognition (NER): Identifying and classifying entities (e.g., names of people, locations, organizations) in text. It enhances understanding of key elements in text and aids in information extraction.
- Part-of-Speech (POS) Tagging: Assigning grammatical categories (e.g., noun, verb) to words in a sentence. Helps understand the syntactic structure and role of each word in a sentence.
- Syntax and Grammar Analysis: Analyzing the structure and grammar of sentences. With it, you can understand the relationships between words and the overall syntactic structure of language.
What Is NLU?
NLU stands for Natural Language Understanding. It’s a subset of NLP that aims to enable machines to comprehend and interpret human language.
Remember, NLU is not limited to recognizing patterns and structures in text. It dives much deeper insights and understands language’s meaning, context, and complexities.
It’s not limited to superficial understanding of data only. It has a broader impact and allows machines to comprehend input, thus understanding emotional and contextual touch.
Key Components Of NLU
Now, let’s discuss some of the major components of NLU. It will help you understand NLU in detail.
- Sentiment Analysis: Determining the sentiment expressed in a text (positive, negative, neutral). It is useful in understanding user opinions and emotions.
- Intent Recognition: Identifying the purpose or intent behind a user’s input. Crucial for understanding user queries and providing relevant responses.
- Syntactic Analysis: Analyzing the grammatical structure of sentences. Helps in understanding the syntactic relationships between words and phrases.
- Context Awareness: Understanding the context in which language is used. Enables systems to comprehend ambiguous language and respond appropriately.

Major Differences Which’ll Help You Choose Between NLP & NLU
At first glance, these technologies might appear similar. But the truth is they are extremely different from each other. Here are four major areas of differences you must know.
Understand The Focus And Scope
NLP deals with syntactic and structural parts of language. The machine can understand the grammar and structure of sentences and text through this.
Meanwhile, with the help of surface-level inspection, these tasks allow machines to understand and improve the basic framework for processing and analysis.
But NLU is concerned with high-level understanding.
This machine doesn’t just focus on grammatical structure but highlights necessary information, actionable insights, and other essential details.
Identify Goals And Objectives
Just by the name, you can tell that the initial goal of Natural Language Processing is processing and manipulation. It emphasizes the need to understand interactions between computers and human beings.
Thus, developing algorithms and techniques through which machines get the ability to process and then manipulate data (textual and spoken language) in a better way.
Meanwhile, NLU goes one step ahead of that. It doesn’t just do basic processing; instead, it comprehends and then extracts meaning from your data.
But how does it help machines?
Basically, with this technology, the aim is to enable machines to understand and interpret human language.
Usage of Techniques And Approaches
In NLP, statistical models and rule-enabled systems are incorporated. These often rely heavily on linguistic rules and patterns. The text is analyzed and then further generated based on these rules and patterns.
These handcrafted rules are made in a way that ensures the machine understands how to connect each element. Now, it can be grammatical rules or syntactic structures.
In NLU, deep learning and ML techniques are used. The neural networks and algorithm are used so the machine is trained using a large amount of data. It ultimately results in a better understanding and interpretation of language.
Determine Levels Of Understanding
Remember that NLP can easily do surface-level processing. That’s why simple tasks such as sentence structure, syntactic analysis, and order of words are easy.
However, when it comes to advanced and complex tasks of understanding deeper semantic layers of speech implementing NLP is not a realistic approach.
But with NLU, you can do it. It has a deep semantic understanding. Moreover, it is a multi-faceted analysis to understand the context of the data based on the textual environment. With NLU techniques, the system forms connections within the text and use external knowledge.
NLU vs. NLP Applications
NLP and NLU are used in various industries and have unique capabilities. Let’s look at some of the applications that utilize these technologies.
|Automatic text summarizer
|Q&A and semantic parsing
|Sentiment analysis & emotion detection
|Both NLP and NLU
Which One Is Better: NLU or NLP?
If you’re finding the answer to this question, then the truth is that there’s no definitive answer. Both of these fields offer various benefits that can be utilized to make better machines.
The superiority depends on the specific task or application. NLP excels in tasks that are related to processing and generating human-like language.
Meanwhile, NLU is exceptional when building applications requiring a deep understanding of language. It comprehends user queries and context-aware search engines.
So what’s the verdict?
Neither is universally better than the other. Moreover, they complement each other. But the choice depends on the goals and requirements of the particular use.
Do You Need Both NLP And NLU?
Is using both good practices?
Is this necessary?
If you want to create robust autonomous machines, then it’s important that you cannot only process the input but also understand the meaning behind the words.
What’s the significance?
It enables machines to produce appropriate, relevant, and accurate interaction responses.
Let’s understand it better with this example.
Chatbots started as simple tools that send automated messages. The focus was on rule-based interactions only. So, if you’re conversing with a chatbot but decide to stray away for a moment, you would have to start again. The best option was to wait till a human takes over the conversation.
But that’s when NLP and NLU united and changed chatbots forever.
Now, chatbots can understand the context of conversation. They can extract data from the conversation based on its meanings.
E-commerce websites heavily focus on sentiment analysis of customer reviews.
Was the review positive?
What changes could they make?
Was the response from customers neutral?
That’s what Luminoso does as well. This tool is designed with the latest technologies to provide sentiment analysis. It helps you grow your business and make changes according to customer feedback.
In a nutshell, developers should be fully aware of these topics. It’ll help create a machine that can interact with humans and engage with them in an engaging way. Remember that using the right technique for your project is crucial to its success.
NLP focuses on language processing generation; meanwhile, NLU dives deeper into comprehension and interpretation.
Together they are shaping the future of human-computer interaction and communication. It’s important to be updated regarding these changes and innovations in the world so you can use these natural language capabilities to their fullest potential for your business success.
