To learn more about Language Models (especially the so-called Transformer Models like “BERT”, resp. “roBERTa”, etc.) as well as trends and obstacles in the field of NLP, please read the article on NLP trends by our colleague Dominique Lade. To give you an idea of the possibilities NLP opens up in the business context today, I will present five practical use cases and explain the solutions behind them in the following. Discover the critical processes, strategies, and best-practices that allow established companies to adopt AI successfully, and generate an ROI.
Language models are generally AI models using NLP and DL to output speech and human-like text. A question-answering system is an approach to retrieving relevant information from a data repository. Based on the available data, the system can provide the most accurate response. Over time, machine learning based on NLP improves the accuracy of the question-answering system. In this way, the QA system becomes more reliable and smarter as it receives more data.
Natural Language Processing (NLP) vs Natural Language Understanding (NLU) vs Natural Language Generation (NLG)
Arguably, the worst part is the fact that some of these voice-cloning solutions are free, open-source and easily available on sites like Github. Because there is only a singular aspect to emulate (how a person sounds), it’s easier to replicate only their voice, inflections and all the nuances that make up that person in the ear of the beholder. Maintenance and repair – NLP can analyse data through sensors and equipment in order to predict the likelihood of maintenance development in natural language processing and/or repairs, reducing downtime while significantly improving efficiency. To stay cutting-edge, users should monitor the current innovations and evaluate whether an upgrade would be worthwhile. Discover new opportunities for your travel business, ask about the integration of certain technology, and of course – help others by sharing your experience. Stopwords are the most common words in a language that are needed for basic grammar and sentence structure.
- They can even measure the sentiment behind certain text and speech (see sidebar, “Applications of natural language technologies”).13 These capabilities (figure 2) allow government agencies to recognize patterns, categorize topics, and analyze public opinion.
- NLP capabilities have the potential to be used across a wide spectrum of government domains.
- To illuminate the concept better, let’s have a look at two of the most top-level techniques used in NLP to process language and information.
- But in the past two years language-based AI has advanced by leaps and bounds, changing common notions of what this technology can do.
- Throughout his career, Cem served as a tech consultant, tech buyer and tech entrepreneur.
- This huge amount of text data has a large potential for business growth and useful analytics.
- Others, like GPT-3, are more convenient in that they can learn a variety of linguistic tasks directly during prediction (zero- or few-shot prediction).
CAC – Computer Assisted Coding tools are custom-built pieces of software which screen medical documentations and produce medical codes pertaining to specific phrases and terminologies within that document. NLP-based CAC tools can analyse and interpret raw or unstructured healthcare data in order to extract the desired features (such as medical facts) pertaining to the assigned codes. NLP has been used to identify misspelled words by cross-matching them against a set of relevant words in the dictionary, which is used as a training set. The misspelled word is then inputted into a ML algorithm to calculate the word’s deviation percentage from the correct one, which has already been fed into the training set. It then either removes, adds, or replaces specific letters from the word, matching it with a word candidate which best fits the intended meaning of the sentence.
NLP is a Deep Learning Technology
This is infinitely helpful when trying to communicate with someone in another language. Not only that, but when translating from another language to your own, tools now recognize the language based on inputted text and translate it. Natural language understanding (NLU) is a subset of NLP that focuses on analyzing the meaning behind sentences.
While we can’t cover all possible NLP use cases under one article, we have certainly shed enough light, hopefully, for businesses across multiple sectors to sit up and take notice. NLP capabilities are only going to improve in the coming years and you need natural language processing services that can help you become more productive, competitive, and risk-free than you thought possible. Not only that, but the right NLP partner can help you identify issues within your organisational departments that you may not even know existed.

Text analytics can be used to understand and identify data patterns and make business decisions. These methods include word/phase-frequency calculation, word cloud generation, sentiment analysis, and others. The global natural language processing (NLP) market was estimated at ~$5B in 2018 and is projected to reach ~$43B in 2025, increasing almost 8.5x in revenue.
These so-called “Language Models” are based on huge text corpora of Facebook, Google, etc., (pre-)trained by randomly masking individual words in the texts and predicting them in the course of training. This is so-called self-supervised learning, which no longer requires a separate target variable. In the course of the training, these models learn a contextual understanding of texts. Additionally, NLP can be used to summarize resumes of candidates who match specific roles in order to help recruiters skim through resumes faster and focus on specific requirements of the job. Some of the famous language models are GPT transformers which were developed by OpenAI, and LaMDA by Google. These models were trained on large datasets crawled from the internet and web sources in order to automate tasks that require language understanding and technical sophistication.
The evolution of NLP
Automated NLG systems produce human-readable text, such as articles, reports, and summaries, to automate the production of documents. NLP-enabled chatbots can offer more personalized responses as they understand the context of conversations and can respond appropriately. Chatbots using NLP can also identify relevant terms and understand complex language, making them more efficient at responding accurately.
Suddenly, what had been machine learning — or “analytical AI” that could produce recommendations based on financial, sales, and marketing data — became natural-language processing. A brand new employee could suddently ask the corporate generative AI (genAI) application for an answer to an in-depth client question. Seasoned employees could ask the platform for information about company benefits or how to get a new laptop.
What is NLP used for?
Text classification, clustering, and sentiment analysis are some of the techniques used by NLP to process large quantities of text data. To improve their products and services, businesses use sentiment analysis to understand the sentiment of their customers. As well as gauging public opinion, it is also used to measure the popularity of a topic or event. Fintech involves handling real-time transactions, securely managing assets, fraud detection, and more.
Machine learning experts then deploy the model or integrate it into an existing production environment. The NLP model receives input and predicts an output for the specific use case the model’s designed for. By giving different example phrases (“How do I get from … to … from … to …”, “When is the next bus from … to …”) to a language model, the chatbot can assign even unseen input to the correct intend (see text classification).
Due to this ability, deep learning algorithms can expose telltale signs that can help businesses detect deepfake fraud. For visual media, this includes variations in lighting and skin tone, twitchy and unnatural motions and millisecond out-of-sync audio-to-video movements (speech-to-lip) nuances that would likely escape human detection. In terms of audio spoofing detection, there are deep learning-powered techniques targeting subtle differences in the high frequencies between real and fake files, data augmentation methods and affective computing.
NLP can address critical government issues
It also allows for parallel computation and, thus, faster and more efficient training. Finally, people have done away with recurrence and proposed the attention mechanism, as incorporated in the Transformer architecture. Attention allows the model to focus back and forth between different words during prediction. Each word is weighted according to its relevance for the specific position to be predicted.
This opens up more opportunities for people to explore their data using natural language statements or question fragments made up of several keywords that can be interpreted and assigned a meaning. Applying language to investigate data not only enhances the level of accessibility, but lowers the barrier to analytics across organizations, beyond the expected community of analysts and software developers. To learn more about how natural language can help you better visualize and explore your data, check out this webinar. This involves classifying texts into predefined sentiment categories (e.g., negative/positive). This information is particularly important in the financial world or for social media monitoring.
