Understanding Natural Language Processing: What It Is and How It Works

January 26, 2023

Natural Language Processing (NLP) is an area of Artificial Intelligence (AI) that focuses on the understanding and analysis of human language. It enables machines to interact with humans in their own natural language, allowing for more efficient communication between humans and computers. NLP utilizes a variety of techniques to break down the text into its component parts, analyze each part for meaning, and then use this information to make decisions or predictions. By using these methods, machines can understand how people communicate in order to better respond or help them solve problems.

In this article, we will discuss what Natural Language Processing is and how it works. 

What is Natural Language Processing?

Natural Language Processing is a subfield of Artificial Intelligence that focuses on enabling computers to understand human language. It utilizes a variety of techniques, including machine learning, natural language understanding, and search algorithms. NLP applies these techniques to analyze the text or speech of a person, breaking it down into its components and then piecing them back together to gain an understanding of the meaning behind it.

How Does Natural Language Processing Work?

NLP utilizes a variety of techniques to process natural language. First, it breaks down the language into its component parts, such as words and sentences. Then, it uses algorithms and machine learning to understand the meaning of each part. Finally, it utilizes search techniques to determine the best response or action for a given situation.

NLP is used in many areas of technology, from natural language understanding in chatbots to sentiment analysis in social media. It’s also used for medical diagnosis, voice recognition, document summarization, and many more applications.

Examples of Natural Language Processing

The possibilities of Natural Language Processing (NLP) are seemingly infinite and continue to expand. Here is a list of some popular use cases for NLP:

Automated phone calls

By utilizing Natural Language Processing (NLP), customer service lines are able to respond appropriately when customers verbally interact with their automated systems.


Your phone’s NLP technology allows it to learn from your communications, like making text suggestions and autocorrecting errors. If you type a name with an offbeat spelling often enough, for instance, the device will start recognizing this pattern over time and provide more customized advice and corrections. This way, you don’t have to worry about typing the same words differently each time – just let tech do its job!

Virtual assistants

Utilizing the power of Natural Language Processing (NLP), virtual assistants like Alexa, Siri, and Google Voice can comprehend your verbal commands allowing them to respond more quickly and accurately.

Automated captions

If you’re familiar with watching videos online, chances are you’ve encountered the option of enabling closed captions. With automated speech recognition (ASR) technology utilized by many platforms to automatically produce and display onscreen captions for visuals, Natural Language Processing (NLP) is what propels AI systems to transform spoken words into written form.

It is essential to keep in mind that while auto-captions are handy and easy to obtain, they can often fail to meet specific criteria. In order to adhere to stringent regulations such as the Americans with Disabilities Act, it would be wise for organizations or businesses to utilize both AI transcription software and human transcribers. Combining the aptitude of humans and machines will generate more precise captions.


By leveraging Automatic Speech Recognition (ASR) software, devices can be granted the incredible ability to convert spoken words into written text. This ASR technology is powered by Natural Language Processing solutions which enable it to accurately interpret what’s said and transcribe it accordingly.

The usage in Natural Language Processing 

Natural language processing has revolutionized the way technology interacts with humans due to its capacity for learning and development. Here are some of the most popular applications of NLP:


By utilizing NLP, chatbots are able to understand and respond to human commands in a natural way. These bots can be deployed on websites or messaging platforms like Facebook Messenger and Slack, increasing customer engagement and providing an efficient way of managing inquiries.

Recommendation systems

Natural Language Processing is being used by many companies to build personalized recommendation systems. By scanning through user profiles, reviews and ratings, these systems are able to accurately identify products or services that are tailored to the user’s interests.

Sentiment analysis

NLP enables businesses to gain an understanding of customer sentiment by analyzing the words used in product reviews, social media comments, and other forms of text data. This allows them to adjust their products and services accordingly.

Text summarization

NLP can be used to automatically summarize long articles or documents into shorter versions that capture the main points of the content, saving time for readers. This technology is especially useful in media outlets, where journalists can quickly scan through a large amount of information to identify key topics.


Natural Language Processing (NLP) can be used to make the interactions between humans and technology more efficient, natural, and personalized. By utilizing NLP, businesses are able to build chatbots, recommendation systems, sentiment analysis tools, text summarization software, and much more. With a growing demand for machine-driven communication solutions, Natural Language Processing is sure to be an invaluable technology in the years to come.
