What can Natural Language Processing be used for?

Natural Language Processing (NLP) is a powerful technology that can be used in many ways to solve real-world problems. In this post, we will explore the various applications of NLP and explain how they work. 


Chatbots are a great way to interact with users and help them get the information they need. They can also be used in a variety of ways, such as helping you find products or services, or making purchases for you. Chatbots are an excellent way to engage with your customers because they don’t require much effort from the user but can still provide them with a positive experience.

Sentiment analysis 

Sentiment analysis is a useful tool for customer service, brand management, and marketing. It involves determining whether a piece of text expresses positive or negative emotions. This information can be used to improve the quality of customer service interactions or to better understand how people feel about your brand and products. 

Sentiment analysis can be applied to many different types of data: customer reviews and feedback, social media posts (Facebook, Twitter, etc.), news articles, and more.

Information extraction

Information extraction is the process of extracting structured data from unstructured text. 

Example use cases include: 

  • Detecting parts in a document, such as company name, invoice position, invoice date, and price. This is done by using machine learning algorithms to build a model that can recognize these elements. 
  • Extracting the main idea of a document or news article. This can be done by analyzing text for keywords and common structures, such as lists and paragraphs.

Language Translation

The ability to translate text from one language to another is a feature of NLP.  NLP can be used to translate between languages that are similar, but not identical. For example: from English to French or Spanish; from Dutch to Afrikaans; from Farsi to Arabic; etc… It can also translate between completely different languages, such as English and Mandarin Chinese (which have very different grammatical structures). 

Image captioning

Image captioning is the process of automatically generating a text description of an image. It can be used to describe your vacation photos, or even to make searching for content easier. For example, if you upload a picture of a cat and caption it “very cute”, someone may be able to search for pictures that are also very cute based on your caption – or you can also use NLP to generate the captions for you. 

Text summarization and generation

Text summarization is the process of reducing a text document into a shorter version. It’s used in many different ways, such as for news articles, emails, and social media. Text summarization can also be used to generate new text from an existing text—for example, by rewriting an article or writing a summary of an event. 

Text summarization involves identifying the main ideas in a document and presenting them in another form more suitable for consumption by humans (and sometimes machines). For example, if you had published an article on your company website about how you plan to grow your business next year but are worried that no one will read it because it’s too long and complicated, then you might want to turn that information into something shorter that gives the same level of detail but is easier for people to understand and remember.

Speech-to-text and text-to-speech

Speech-to-text and text-to-speech are the common techniques used, for example, in chatbots and call centers. These technologies are more and more frequently used also for the automatic transcription of calls, or to create subtitles in movies. These techniques are also used in virtual assistants such as Alexa or Google Assistant.
NLP enables us to work with a wide spectrum of languages, with always more languages being supported. 

Question answering

With the great advances in NLP in the last years, we are now able to use the potential of Large Language Models to achieve state-of-the-art results in many NLP tasks and to achieve great results in areas which were hard to implement before. One such example is question answering. In short, it allows us to create a knowledge base and search through to answer the questions written in natural language. We don’t have to foresee and prepare the answers for all possible questions but let the AI models find the best suited answer in the text, which can be for example a company website. 

NLP is being used in many ways

NLP is a powerful tool that can be utilized in many industries. It’s no wonder that there are so many uses for NLP! It’s being used to create new products and services, improve existing products and services, analyze data from social media platforms like Twitter and Reddit—the list goes on! 

Some examples include:

A virtual assistant like Siri or Alexa uses NLP to understand your questions and requests. These assistants can be programmed to respond appropriately based on what they hear from you (for example, “Where’s the nearest coffee shop?”). They also use NLP so that when you ask them a question about something specific (like “Is today Friday?”), they’ll tell you if it’s Tuesday instead of telling you yes despite mistaking Thursday for Friday (the day after). This allows users to get more accurate results than if they were just guessing. 

Tools such as Google Translate or DeepL help people communicate when they don’t speak each other’s language fluently or at all; this makes communication across borders easier than ever before!

Natural Language Processing: Conclusion

It is clear that NLP has many uses in the world of technology and business. Businesses are using it to improve customer service, create more efficient workflows, and develop new products that appeal to their customers’ needs.  

Consumers can use NLP to communicate more effectively with AI assistants like Alexa or Siri as well as receive better recommendations based on their search history and interests—all without having to type a thing!
