5 Amazing Examples Of Natural Language Processing NLP In Practice

Monday November 7th, 2022

As another example, a sentence can change meaning depending on which word or syllable the speaker puts stress on. NLP algorithms may miss the subtle, but important, tone changes in a person’s voice when performing speech recognition. The tone and inflection of speech may also vary between different accents, which can be challenging for an algorithm to parse. This involves automatically summarizing text and finding important pieces of data.

  • On the other hand, sentiment analysis focuses on identifying and determining whether or not the author of a post holds a negative, positive, or neutral opinion of a brand.
  • If you publish just a few pieces a month and need a quick summary, this might be a useful tool.
  • When suggesting keywords relevant to you, Google relies on a wealth of data that catalogs what other consumers search for when entering specific search terms.
  • Then it adapts its algorithm to play that song – and others like it – the next time you listen to that music station.
  • Not only are there hundreds of languages and dialects, but within each language is a unique set of grammar and syntax rules, terms and slang.
  • There’s also some evidence that so-called “recommender systems,” which are often assisted by NLP technology, may exacerbate the digital siloing effect.

Government agencies are bombarded with text-based data, including digital and paper documents. Content marketers also use sentiment analysis to track reactions to their own content on social media. Sentiment analysis tools look for trigger words like wonderful or terrible.

Search results

NLP can help businesses in customer experience analysis based on certain predefined topics or categories. It’s able to do this through its ability to classify text and add tags or categories to the text based on its content. In this way, organizations can see what aspects of their brand or products are most important to their customers and understand sentiment about their products. Here, one of the best NLP examples is where organizations use them to serve content in a knowledge base for customers or users.

Here is where natural language processing comes in handy — particularly sentiment analysis and feedback analysis tools which scan text for positive, negative, or neutral emotions. We all hear “this call may be recorded for training purposes,” but rarely do we wonder what that entails. Turns out, these recordings may be used for training purposes, if a customer is aggrieved, but most of the time, they go into the database for an NLP system to learn from and improve in the future. Automated systems direct customer calls to a service representative or online chatbots, which respond to customer requests with helpful information.

How NLP Works

In the code snippet below, many of the words after stemming did not end up being a recognizable dictionary word. In the code snippet below, we show that all the words truncate to their stem words. However, notice that the stemmed word is not a dictionary word. Next, we are going to remove the punctuation marks as they are not very useful for us.


Predictive text will customize itself to your personal language quirks the longer you use it. This makes for fun experiments where individuals will share entire sentences made up entirely of predictive text on their phones. The results are surprisingly personal and enlightening; they’ve even been highlighted by several media outlets.

Natural language processing in business

Computers were becoming faster and could be used to develop rules based on linguistic statistics without a linguist creating all of the rules. Data-driven natural language processing became mainstream during this decade. Natural language processing shifted from a linguist-based approach to an engineer-based approach, drawing on a wider variety of scientific disciplines instead of delving into linguistics.

  • To put it simply, a search bar with an inadequate natural language toolkit wastes a customer’s precious time in a busy world.
  • NLP is special in that it has the capability to make sense of these reams of unstructured information.
  • Since it translates a user’s, and in the case of e-commerce, a customer’s intent, it allows businesses to provide a better experience through a text-based search bar, exponentially increasing RPV for your brand.
  • Head over to the on-demand library to hear insights from experts and learn the importance of cybersecurity in your organization.
  • The computer uses this data to find patterns and anticipate what comes next.
  • If you’re currently collecting a lot of qualitative feedback, we’d love to help you glean actionable insights by applying NLP.

example of nlps, phrases, sentences, and sometimes entire books are fed into the ML engines, where they are processed based on grammar rules, people’s real-life language habits, or both. The computer uses this data to find patterns and anticipate what comes next. Machine learning systems store words and information in the different ways they are put together like any other form of data. Natural Language Understanding helps the machine to understand and analyse human language by extracting the metadata from content such as concepts, entities, keywords, emotion, relations, and semantic roles.

Benefits of natural language processing

This function predicts what you might be searching for, so you can simply click on it and save yourself the hassle of typing it out. IBM’s Global Adoption Index cited that almost half of businesses surveyed globally are using some kind of application powered by NLP.

What is an example of NLP in artificial intelligence?

These smart assistants, such as Siri or Alexa, use voice recognition to understand our everyday queries, they then use natural language generation (a subfield of NLP) to answer these queries.

In many ways, the models and human language are beginning to co-evolve and even converge. As humans use more natural language products, they begin to intuitively predict what the AI may or may not understand and choose the best words. Speech recognition, also called speech-to-text, is the task of reliably converting voice data into text data. Speech recognition is required for any application that follows voice commands or answers spoken questions. What makes speech recognition especially challenging is the way people talk—quickly, slurring words together, with varying emphasis and intonation, in different accents, and often using incorrect grammar. The top-down, language-first approach to natural language processing was replaced with a more statistical approach, because advancements in computing made this a more efficient way of developing NLP technology.

Methods: Rules, statistics, neural networks

Text analytics is used to explore textual content and derive new variables from raw text that may be visualized, filtered, or used as inputs to predictive models or other statistical methods. Natural language processing helps computers communicate with humans in their own language and scales other language-related tasks. For example, NLP makes it possible for computers to read text, hear speech, interpret it, measure sentiment and determine which parts are important.


The NLTK includes libraries for many of the NLP tasks listed above, plus libraries for subtasks, such as sentence parsing, word segmentation, stemming and lemmatization , and tokenization . It also includes libraries for implementing capabilities such as semantic reasoning, the ability to reach logical conclusions based on facts extracted from text. Natural language processing is behind the scenes for several things you may take for granted every day.

Natural language processing can be leveraged to help insurers identify fraudulent claims. By analyzing customer communication and even social media profiles, AI can identify indicators of fraud and flag such claims for further inspection. Apply the theory of conceptual metaphor, explained by Lakoff as “the understanding of one idea, in terms of another” which provides an idea of the intent of the author. When used in a comparison (“That is a big tree”), the author’s intent is to imply that the tree is physically large relative to other trees or the authors experience.
