NLP vs NLU are paramount in deciphering human language to understand a customer’s needs and serve the business better. It allows ventures to carry themselves out efficiently. NLP (Natural language understanding) and NLU (Natural language processing) aid in performing tasks that assist human language. It can be messy and confusing at times.

These systems help understand the context, sentiment, and rationale of human language, thus helping the overall process. However, NLP vs NLU is often mistaken for one another. They work in tandem but differ in their function. They can be interchanged since their rationale serves the same purpose.

NLU and NLP are characterized by artificial intelligence.


NLP is responsible for undertaking massive amounts of data and contains a comprehensive system to make sense of the interaction between humans and the design. It includes reading, understanding, and making sound decisions.

The most common examples of NLP are information extraction, speech generation, parsing, and speech recognition. In real life, companies use it for text mining, machine translation, chatbot, and stemming.

For example, a customer asks a question in the chatbots; the algorithms will examine the data by studying keywords to find a suitable response. It thoroughly scrutinizes the available data to provide correct answers. NLP is an overarching system that takes in the input to provide apt output.

NLP operates on a more comprehensive structure and enables decision-making in conjunction with understanding the data. It studies the available archives to make informed choices. The machine processes the provided information and makes decisions for you. It responds to the system and is driven by the end-to-end process. It converts unstructured data to structured data.


It is paramount in comprehending the data received. Companies use it to interpret the data and process it in accordance. NLU does so by deciphering the context, semantics, syntax, intent, and sentiment of the text. Numerous tools, techniques, and models are employed to complete the process successfully. They interpret the rationale behind the text by using three linguistic tools:

  • Syntax: Syntax comprehends sentences and phrases and verifies the provided material’s grammar and syntax.
  • Semantic: It deciphers the intent of the text.
  • Pragmatic: Interprets the context to understand what the text is attempting to propagate.

NLU is centered on understanding more unstructured data and performing more complicated operations. It delves into the intricacies and flaws of the format to provide structure and correction. The most common use of NLU is semantics, phrasing, semantic analysis, dialogues, etc.

NLU is more narrow and focuses on understanding the text. It intends to understand what goes beyond the obvious. NLU is equipped to tackle the flaws made in sentences and reflect correct outcomes by correcting them. It has the propensity of understanding the text and making meaning out of it. The process involves reading data and converting it into structured information.


NLU is a part of NLP and helps to make NLP more efficacious. They work in tandem to enhance human interactions and human process language. Processing and understanding human language involves several intricacies like science, linguistic techniques, etc. NLU and NLP facilitate this process with utmost sincerity.


Companies can provide a human-like experience to their customers and ensure satisfaction. People feel more at ease when they speak to an AI that can comprehend their queries.
