Beyond just its awesome data analyzation capabilities, NLP has a number of benefits that a company in any industry would appreciate. Quora like applications use duplicate detection technology to keep the site functioning smoothly. The MasterCard virtual assistant chatbot can provide a 360 eagle view of the user spending habits along with offering them what benefits they can take from the card. Chatbots are the most integral part of any mobile app or a website and integrating NLP into them can increase the usefulness.

Using NLP, more specifically sentiment analysis tools like MonkeyLearn, to keep an eye on how customers are feeling. You can then be notified of any issues they are facing and deal with them as quickly they crop up. Natural language processing is developing at a rapid pace and its applications are evolving every day. That’s great news for businesses since NLP can have a dramatic effect on how you run your day-to-day operations. It can speed up your processes, reduce monotonous tasks for your employees, and even improve relationships with your customers.

Publishers and information service providers can suggest content to ensure that users see the topics, documents or products that are most relevant to them. With the recent focus on large language models (LLMs), AI technology in the language domain, which includes NLP, is now benefiting similarly. You may not realize it, but there are countless real-world examples of NLP techniques that impact our everyday lives.

Still, as we’ve seen in many NLP examples, it is a very useful technology that can significantly improve business processes – from customer service to eCommerce search results. Optical Character Recognition (OCR) automates data extraction from text, either from a scanned document or image file to a machine-readable text. For example, an application that allows you to scan a paper copy and turns this into a PDF document. After the text is converted, it can be used for other NLP applications like sentiment analysis and language translation. By performing sentiment analysis, companies can better understand textual data and monitor brand and product feedback in a systematic way.

Likewise, NLP is useful for the same reasons as when a person interacts with a generative AI chatbot or AI voice assistant. Instead of needing to use specific predefined language, a user could interact with a voice assistant like Siri on their phone using their regular diction, and their voice assistant will still be able to understand them. Today, employees and customers alike expect the same ease of finding what they need, when they need it from any search bar, and this includes within the enterprise.

For example, the TextBlob libraryOpens a new window , written for NLTK, is an open-source extension that provides machine translation, sentiment analysis, and several other NLP services. Because of their complexity, generally it takes a lot of data to train a deep neural network, and processing it takes a lot of compute power and time. Modern deep neural network NLP models are trained from a diverse array of sources, such as all of Wikipedia and data scraped from the web. The training data might be on the order of 10 GB or more in size, and it might take a week or more on a high-performance cluster to train the deep neural network. (Researchers find that training even deeper models from even larger datasets have even higher performance, so currently there is a race to train bigger and bigger models from larger and larger datasets). Called DeepHealthMiner, the tool analyzed millions of posts from the Inspire health forum and yielded promising results.

In this blog, we bring you 14 NLP examples that will help you understand the use of natural language processing and how it is beneficial to businesses. Through these examples of natural language processing, you will see how AI-enabled platforms understand data in the same manner as a human, while decoding nuances in language, semantics, and bringing insights to the forefront. There are several NLP techniques that enable AI tools and devices to interact with and process human language in meaningful ways. NLP techniques are widely used in a variety of applications such as search engines, machine translation, sentiment analysis, text summarization, question answering, and many more. NLP research is an active field and recent advancements in deep learning have led to significant improvements in NLP performance.

An example is the classification of product reviews into positive, negative, or neutral sentiments. NLP provides advantages like automated language understanding or sentiment analysis and text summarizing. It enhances efficiency in information retrieval, aids the decision-making cycle, and enables intelligent virtual assistants and chatbots to develop. Language recognition and translation systems in NLP are also contributing to making apps and interfaces accessible and easy to use and making communication more manageable for a wide range of individuals. Furthermore, NLP empowers virtual assistants, chatbots, and language translation services to the level where people can now experience automated services’ accuracy, speed, and ease of communication.

In addition, it can offer autocorrect suggestions and even learn new words that you type frequently. These models can be written in languages like Python, or made with AutoML tools like Akkio, Microsoft Cognitive Services, and Google Cloud Natural Language. Email service providers have evolved far beyond simple spam classification, however. Gmail, for instance, uses NLP to create “smart replies” that can be used to automatically generate a response. Every Internet user has received a customer feedback survey at one point or another.

Apart from allowing businesses to improve their processes and serve their customers better, NLP can also help people, communities, and businesses strengthen their cybersecurity efforts. Apart from that, NLP helps with identifying phrases and keywords that can denote harm to the general public, and are highly used in public safety management. They also help in areas like child and human trafficking, conspiracy theorists who hamper security details, preventing digital harassment and bullying, and other such areas.

While tools like SurveyMonkey and Google Forms have helped democratize customer feedback surveys, NLP offers a more sophisticated approach. By extracting meaning from written text, NLP allows businesses to gain insights about their customers and respond accordingly. Topic modeling is exploring a set of documents to bring out the general concepts or examples of natural language processing main themes in them. NLP models can discover hidden topics by clustering words and documents with mutual presence patterns. Topic modeling is a tool for generating topic models that can be used for processing, categorizing, and exploring large text corpora. This involves identifying the appropriate sense of a word in a given sentence or context.

NLP uses computational linguistics, which is the study of how language works, and various models based on statistics, machine learning, and deep learning. These technologies allow computers to analyze and process text or voice data, and to grasp their full meaning, including the speaker’s or writer’s intentions and emotions. Natural language processing (NLP) is an interdisciplinary subfield of computer science and linguistics.

However, there is still a lot of work to be done to improve the coverage of the world’s languages. Facebook estimates that more than 20% of the world’s population is still not currently covered by commercial translation technology. In general coverage is very good for major world languages, with some outliers (notably Yue and Wu Chinese, sometimes known as Cantonese and Shanghainese).

Statistical Language Models are based on probabilistic algorithms that use statistical patterns and probabilities to understand and generate language. When this was about the NLP system gathering data, the text analytics helps in keywords extraction and finding structure or patterns in the unstructured data. In any of the cases, a computer- digital technology that can identify words, phrases, or responses using context related hints. ELECTRA, short for Efficiently Learning an Encoder that Classifies Token Replacements Accurately, is a recent method used to train and develop language models. Instead of using MASK like BERT, ELECTRA efficiently reconstructs original words and performs well in various NLP tasks. RoBERTa, short for the Robustly Optimized BERT pre-training approach, represents an optimized method for pre-training self-supervised NLP systems.

Search engines no longer just use keywords to help users reach their search results. They now analyze people’s intent when they search for information through NLP. Topic modeling uses NLP to analyze a text corpus and summarize it, breaking it down into relevant topics.

They then learn on the job, storing information and context to strengthen their future responses. Because of a combination of NLP and DL, online translators have become powerful tools. When Google Translate first launched, you could use it for word-by-word translations only. Here are five examples of how brands transformed their brand strategy using NLP-driven insights from social listening data.

Natural language processing is behind the scenes for several things you may take for granted every day. When you ask Siri for directions or to send a text, natural language processing enables that functionality. “According to the FBI, the total cost of insurance fraud (non-health insurance) is estimated to be more than $40 billion per year. Insurance fraud affects both insurers and customers, who end up paying higher premiums to cover the cost of fraudulent claims. Insurers can use NLP to try to mitigate the high cost of fraud, lower their claims payouts and decrease premiums for their customers. NLP models can be used to analyze past fraudulent claims in order to detect claims with similar attributes and flag them.

Once you get the hang of these tools, you can build a customized machine learning model, which you can train with your own criteria to get more accurate results. While there are many challenges in natural language processing, the benefits of NLP for businesses are huge making NLP a worthwhile investment. Once NLP tools can understand what a piece of text is about, and even measure things like sentiment, businesses can start to prioritize and organize their data in a way that suits their needs. As a matter of fact, chatbots had already made their mark before the arrival of smart assistants such as Siri and Alexa.

This is also called “language out” by summarizing by meaningful information into text using a concept known as “grammar of graphics.” Combining AI, machine learning and natural language processing, Covera Health is on a mission to raise the quality of healthcare with its clinical intelligence platform.

Another powerful natural language processing example works in tandem with your review response strategy. Specifically, companies can use NLP to address online reviews that have specific keywords with negative sentiments. Not only does this help dictate changes in the experience; it’s also a way to address issues and maintain a strong online reputation. NLP powers social listening by enabling machine learning algorithms to track and identify key topics defined by marketers based on their goals. Grocery chain Casey’s used this feature in Sprout to capture their audience’s voice and use the insights to create social content that resonated with their diverse community. Machine learning AIs have advanced to the level today where natural language processing can analyze, extract meaning from, and determine actionable insights from both syntax and semantics in text.

Built on BERT’s language masking strategy, RoBERTa learns and predicts intentionally hidden text sections. As a pre-trained model, RoBERTa excels in all tasks evaluated by the General Language Understanding Evaluation (GLUE) benchmark. Prominent examples of large language models (LLM), such as GPT-3 and BERT, excel at intricate tasks by strategically manipulating input text to invoke the model’s capabilities. The HMM was also applied to problems in NLP, such as part-of-speech taggingOpens a new window (POS). POS tagging, as the name implies, tags the words in a sentence with its part of speech (noun, verb, adverb, etc.).

• NLP algorithms detect and process data in scanned documents that have been converted to text by optical character recognition (OCR).
• These monitoring tools leverage the previously discussed sentiment analysis and spot emotions like irritation, frustration, happiness, or satisfaction.
• These assistants use natural language processing to process and analyze language and then use natural language understanding (NLU) to understand the spoken language.
• We examine the potential influence of machine learning and AI on the legal industry.

Topic modeling can reduce volumes of text down to a list of topics, revealing semantic structures that are difficult for humans to detect. Likewise, evo, an outdoor goods store with locations in Seattle, Portland, and Denver, utilize their NLP reviews to gauge the current state of the customer experience against benchmarks. A great use of NLP software is when a company wants to confirm the effectiveness of a new or ongoing strategy. Getting immediate feedback through online reviews helps to confirm or deny an apparent trend in the customer experience.

Therefore, it is considered also one of the best natural language processing examples. Language models serve as the foundation for constructing sophisticated NLP applications. AI and machine learning practitioners rely on pre-trained language models to effectively build NLP systems. These models employ transfer learning, where a model pre-trained on one dataset to accomplish a specific task is adapted for various NLP functions on a different dataset. Natural language understanding is the capability to identify meaning (in some internal representation) from a text source.

Analyzing the grammatical structure of sentences to understand their syntactic relationships. Spam detection removes pages that match search keywords but do not provide the actual search answers. This week I am in Singapore, speaking on the topic of Natural Language Processing (NLP) at the Strata conference. If you haven’t heard of NLP, or don’t quite understand what it is, you are not alone. Many people don’t know much about this fascinating technology and yet use it every day. “According to research, making a poor hiring decision based on unconscious prejudices can cost a company up to 75% of that person’s annual income.

It’s the social proof teams need to convince decision makers that the natural language processing (NLP) is worth the money and has the potential to bring in considerable returns. By seeing the power of the technology through the eyes of real users, anyone can make a compelling case for its use. The basic components of AI include learning, reasoning, problem-solving, perception, and language understanding. NLP is the technology used to aid computers to understand natural human language. It uses a combination of linguistics, computer science, statistical analysis, and ML to give systems the ability to understand text and spoken words. Natural language understanding (NLU) enables unstructured data to be restructured in a way that enables a machine to understand and analyze it for meaning.

Natural language generation is the ability to create meaning (in the context of human language) from a representation of information. This functionality can relate to constructing a sentence to represent some type of information (where information could represent some internal representation). In certain NLP applications, NLG is used to generate text information from a representation that was provided in a non-textual form (such as an image or a video). The primary goal of natural language processing is to empower computers to comprehend, interpret, and produce human language.

The Wonderboard mentioned earlier offers automatic insights by using natural language processing techniques. It simply composes sentences by simulating human speeches by being unbiased. There are calls that are recorded for training purposes but in actuality, they are recorded to the database for an NLP system to learn and improve services in the future. This is also one of the natural language processing examples that are being used by organizations from the last many years. Connectionist methods rely on mathematical models of neuron-like networks for processing, commonly called artificial neural networks.

Learn more about NLP fundamentals and find out how it can be a major tool for businesses and individual users.

Only then can NLP tools transform text into something a machine can understand. All this business data contains a wealth of valuable insights, and NLP can quickly help businesses discover what those insights are. Top word cloud generation tools can transform your insight visualizations with their creativity, and give them an edge. The rise of human civilization can be attributed to different aspects, including knowledge and innovation.

The goal of a chatbot is to provide users with the information they need, when they need it, while reducing the need for live, human intervention. The information that populates an average Google search results page has been labeled—this helps make it findable by search engines. However, the text documents, reports, PDFs and intranet pages that make up enterprise content are unstructured data, and, importantly, not labeled. This makes it difficult, if not impossible, for the information to be retrieved by search. This powerful NLP-powered technology makes it easier to monitor and manage your brand’s reputation and get an overall idea of how your customers view you, helping you to improve your products or services over time.

However, NLP is still a challenging field as it requires an understanding of both computational and linguistic principles. In summary, Natural language processing is an exciting area of artificial intelligence development that fuels a wide range of new products such as search engines, chatbots, recommendation systems, and speech-to-text systems. As human interfaces with computers continue to move away from buttons, forms, and domain-specific languages, the demand for growth in natural language processing will continue to increase.
