What is Natural Language Understanding & How Does it Work?

Natural language processing tools such as the Wonderboard by Wonderflow gather and analyse customer feedback. Natural language understanding is a field that involves the application of artificial intelligence techniques to understand human languages. Natural language understanding aims to achieve human-like communication with computers by creating a digital system that can recognize and respond appropriately to human speech. Natural Language Understanding (NLU) is the ability of a computer to understand human language. You can use it for many applications, such as chatbots, voice assistants, and automated translation services. NLP powers intelligent chatbots and virtual assistants—like Siri, Alexa, and Google Assistant—which can understand and respond to user commands in natural language.

This amazing ability of search engines to offer suggestions and save us the effort of typing in the entire thing or term on our mind is because of NLP. Now that you have a fair understanding of NLP and how marketers can use it to enhance the effectiveness of their efforts, let’s look at some NLP examples to inspire you. You mistype a word in a Google search, but it gives you the right search results anyway.

Natural Language Processing (NLP) Examples

The goal of question answering is to give the user response in their natural language, rather than a list of text answers. For further examples of how natural language processing can be used to your organisation’s efficiency and profitability please don’t hesitate to contact Fast Data Science. Businesses in industries such as pharmaceuticals, legal, insurance, and scientific research can leverage the huge amounts of data which they have siloed, in order to overtake the competition. As learned earlier, autoencoding models, such as BERT, are used to fill in the missing or masked words in a sentence, producing a semantically meaningful and complete sentence. As learned earlier, the autoregressive models such as GPT, generate a coherent and contextually relevant sentence based on the given input prompt. While traditional NLP algorithms typically only look at the immediate context of words, LLMs consider large swaths of text to better understand the context.

Anyone learning about NLP for the first time would have questions regarding the practical implementation of NLP in the real world. On paper, the concept of machines interacting semantically with humans is a massive leap forward in the domain of technology. Natural language processing (NLP) is the science of getting computers to talk, or interact with humans in human language. You can foun additiona information about ai customer service and artificial intelligence and NLP. Examples of natural language processing include speech recognition, spell check, autocomplete, chatbots, and search engines.

After the text is converted, it can be used for other NLP applications like sentiment analysis and language translation. Sentiment Analysis is also widely used on Social Listening processes, on platforms such as Twitter. This helps organisations discover what the brand image of their company really looks like through analysis the sentiment of their users’ feedback on social media platforms.

It can be used to help customers better understand the products and services that they’re interested in, or it can be used to help businesses better understand their customers’ needs. Natural language understanding is how a computer program can intelligently understand, interpret, and respond to human speech. Natural language generation is the process by which a computer program creates content based on human speech input.

Voice recognition and speech synthesis

Accurately translating text or speech from one language to another is one of the toughest challenges of natural language processing and natural language understanding. With text analysis solutions like MonkeyLearn, machines can understand the content of customer support tickets and route them to the correct departments without examples of natural language employees having to open every single ticket. Not only does this save customer support teams hundreds of hours, but it also helps them prioritize urgent tickets. Before a computer can process unstructured text into a machine-readable format, first machines need to understand the peculiarities of the human language.

Despite these uncertainties, it is evident that we are entering a symbiotic era between humans and machines. Future generations will be AI-native, relating to technology in a more intimate, interdependent manner than ever before. Natural language is often ambiguous, with multiple meanings and interpretations depending on the context. While LLMs have made strides in addressing this issue, they can still struggle with understanding subtle nuances—such as sarcasm, idiomatic expressions, or context-dependent meanings—leading to incorrect or nonsensical responses. Voice recognition, or speech-to-text, converts spoken language into written text; speech synthesis, or text-to-speech, does the reverse. These technologies enable hands-free interaction with devices and improved accessibility for individuals with disabilities.

Reinforcement Learning

Have you ever spoken to Siri or Alexa and marveled at their ability to understand and respond? Intermediate tasks (e.g., part-of-speech tagging and dependency parsing) have not been needed anymore. Although rule-based systems for manipulating symbols were still in use in 2020, they have become mostly obsolete with the advance of LLMs in 2023. In the past years, she came up with many clever ideas that brought scalability, anonymity and more features to the open blockchains.

It enables customers to solve basic problems without the need for a customer support executive. The point here is that by using NLP text summarization techniques, marketers can create and publish content that matches the NLP search intent that search engines detect while providing search results. Marketers use AI writers that employ NLP text summarization techniques to generate competitive, insightful, and engaging content on topics. NLP-based text analysis can help you leverage every “bit” of data your organization collects and derive insights and information as and when required.

• There have also been huge advancements in machine translation through the rise of recurrent neural networks, about which I also wrote a blog post.
• This helps organisations discover what the brand image of their company really looks like through analysis the sentiment of their users’ feedback on social media platforms.
• Try out no-code text analysis tools like MonkeyLearn to  automatically tag your customer service tickets.
• An example of a widely-used controlled natural language is Simplified Technical English, which was originally developed for aerospace and avionics industry manuals.
• It can speed up your processes, reduce monotonous tasks for your employees, and even improve relationships with your customers.

This tool learns about customer intentions with every interaction, then offers related results. If you’re not adopting NLP technology, you’re probably missing out on ways to automize or gain business insights. Natural Language Processing (NLP) is at work all around us, making our lives easier at every turn, yet we don’t often think about it. From predictive text to data analysis, NLP’s applications in our everyday lives are far-ranging. As of 1996, there were 350 attested families with one or more native speakers of Esperanto.

Several prominent clothing retailers, including Neiman Marcus, Forever 21 and Carhartt, incorporate BloomReach’s flagship product, BloomReach Experience (brX). The suite includes a self-learning search and optimizable browsing functions and landing pages, all of which are driven by natural language processing. Natural Language Processing is a subfield of AI that allows machines to comprehend and generate human language, bridging the gap between human communication and computer understanding. The proposed test includes a task that involves the automated interpretation and generation of natural language.

Typically, this term is used when the grammatical structure is simpler than in full natural language. In contrast to sublanguages and fragments of languages, a phraseology is not a selection of sentences but a selection of phrases. Phraseologies can be natural or constructed, and in the latter case they are usually considered CNLs. Social media monitoring uses NLP to filter the overwhelming number of comments and queries that companies might receive under a given post, or even across all social channels. These monitoring tools leverage the previously discussed sentiment analysis and spot emotions like irritation, frustration, happiness, or satisfaction.

In general, there seems to be good evidence for each of the language types that the use of CNL can be advantageous. This depends heavily on the precise problem domain, the background of the users, and—perhaps most importantly—the quality of the design of the language and its supporting tools. These are languages that are considerably simpler than natural languages, in the sense that a significant part of the complex structures are eliminated or heavily restricted. Still, they are too complex to be described in an exact and comprehensive manner.

Additionally, strong email filtering in the workplace can significantly reduce the risk of someone clicking and opening a malicious email, thereby limiting the exposure of sensitive data. From enhancing customer experiences with chatbots to data mining and personalized marketing campaigns, NLP offers a plethora of advantages to businesses across various sectors. With Natural Language Processing, businesses can scan vast feedback repositories, understand common issues, desires, or suggestions, and then refine their products to better suit their audience’s needs.

Only the introduction of hidden Markov models, applied to part-of-speech tagging, announced the end of the old rule-based approach. The models could subsequently use the information to draw accurate predictions regarding the preferences of customers. Businesses can use product recommendation insights through personalized product pages or email campaigns targeted at specific groups of consumers. NLP works through normalization of user statements by accounting for syntax and grammar, followed by leveraging tokenization for breaking down a statement into distinct components. Finally, the machine analyzes the components and draws the meaning of the statement by using different algorithms.

This description should not presuppose intuitive knowledge about any natural language. It is therefore not primarily a measure for the effort needed by a human to learn the language, neither does it capture the theoretical complexity of the language (as, for example, the Chomsky hierarchy does). Rather, it is closely related to the effort needed to fully implement the syntax and the semantics of the language in a mathematical model, such as a computer program. These are languages that do not look natural, making heavy use of symbol characters, brackets, or unnatural keywords. It might be possible to use natural words or phrases as names for certain entities, but this is neither required nor further defined by the language. Phraseology is a term that denotes a “set of expressions used by a particular person or group” (Houghton Mifflin Harcourt 2000).

NLP Limitations

Data cleaning techniques are essential to getting accurate results when you analyze data for various purposes, such as customer experience insights, brand monitoring, market research, or measuring employee satisfaction. We are very satisfied with the accuracy of Repustate’s Arabic sentiment analysis, as well as their and support which helped us to successfully deliver the requirements of our clients in the government and private sector. From helping people understand documents to construct robust risk prediction and fraud detection models, NLP is playing a key role.

By offering real-time, human-like interactions, businesses are not only resolving queries swiftly but also providing a personalized touch, raising overall customer satisfaction. You can also find more sophisticated models, like information extraction models, for achieving better results. The models are programmed in languages such as Python or with the help of tools like Google Cloud Natural Language and Microsoft Cognitive Services.

They now analyze people’s intent when they search for information through NLP. Online translators are now powerful tools thanks to Natural Language Processing. If you think back to the early days of google translate, for example, you’ll remember it was only fit for word-to-word translations. Although natural language processing might sound like something out of a science fiction novel, the truth is that people already interact with countless NLP-powered devices and services every day. Natural language processing ensures that AI can understand the natural human languages we speak everyday. By default, virtual assistants tell you the weather for your current location, unless you specify a particular city.

In general coverage is very good for major world languages, with some outliers (notably Yue and Wu Chinese, sometimes known as Cantonese and Shanghainese). Today, Google Translate covers an astonishing array of languages and handles most of them with statistical models trained on enormous corpora of text which may not even be available in the language pair. Transformer models have allowed tech giants to develop translation systems trained solely on monolingual text.

Search engines use syntax (the arrangement of words) and semantics (the meaning of words) analysis to determine the context and intent behind your search, ensuring the results align almost perfectly with what you’re seeking. When you think of human language, it’s a complex web of semantics, grammar, idioms, and cultural nuances. Imagine training a computer to navigate this intricately woven tapestry—it’s no small feat! Though natural language processing tasks are closely intertwined, they can be subdivided into categories for convenience. Request your free demo today to see how you can streamline your business with natural language processing and MonkeyLearn. Search engines no longer just use keywords to help users reach their search results.

NLP is used in consumer sentiment research to help companies improve their products and services or create new ones so that their customers are as happy as possible. There are many social listening tools like “Answer The Public” that provide competitive marketing intelligence. Concerning type t, it has been reported that the use of the controlled language MCE for machine-assisted translation leads to a “five-to-one gain in translation time” (Ruffino 1982).

You can also check out my blog post about building neural networks with Keras where I train a neural network to perform sentiment analysis. Translation company Welocalize customizes Googles AutoML Translate to make sure client content isn’t lost in translation. This type of natural language processing is facilitating far wider content translation of not just text, but also video, audio, graphics and other digital assets. As a result, companies with global audiences can adapt their content to fit a range of cultures and contexts.

Despite the apparent differences, it seems sensible to put all these languages under the same umbrella. To bring order to the variety of languages, a general classification scheme is presented here. A comprehensive survey of existing English-based CNLs is given, listing and describing 100 languages from 1930 until today. Classification of these languages reveals that they form a single scattered cloud filling the conceptual space between natural languages such as English on the one end and formal languages such as propositional logic on the other.

NLP algorithms can provide a 360-degree view of organizational data in real-time. All you have to do is type or speak about the issue you are facing, and these NLP chatbots will generate reports, request an address change, or request doorstep services on your behalf. For instance, in the “tree-house” example above, Google tries to sort through all the “tree-house” related content on the internet and produce a relevant answer right there on the search results page. And it’s not just predictive text or auto-correcting spelling mistakes; today, NLP-powered AI writers like Scalenut can produce entire paragraphs of meaningful text.

Phone calls to schedule appointments like an oil change or haircut can be automated, as evidenced by this video showing Google Assistant making a hair appointment. There has recently been a lot of hype about transformer models, which are the latest iteration of neural networks. Transformers are able to represent the grammar of natural language in an extremely deep and sophisticated way and have improved performance of document classification, text generation and question answering systems. Agents can also help customers with more complex issues by using NLU technology combined with natural language generation tools to create personalized responses based on specific information about each customer’s situation. When you’re analyzing data with natural language understanding software, you can find new ways to make business decisions based on the information you have.

A widespread example of speech recognition is the smartphone’s voice search integration. This feature allows a user to speak directly into the search engine, and it will convert the sound into text, before conducting a search. There are many eCommerce websites and online retailers that leverage NLP-powered semantic search engines. They aim to understand the shopper’s intent when searching for long-tail keywords (e.g. women’s straight leg denim size 4) and improve product visibility.

Deep 6 AI developed a platform that uses machine learning, NLP and AI to improve clinical trial processes. Healthcare professionals use the platform to sift through structured and unstructured data sets, determining ideal patients through concept mapping and criteria gathered from health backgrounds. Based on the requirements established, teams can add and remove patients to keep their databases up to date and find the best fit for patients and clinical trials. The review of top NLP examples shows that natural language processing has become an integral part of our lives.

Second, the integration of plug-ins and agents expands the potential of existing LLMs. Plug-ins are modular components that can be added or removed to tailor an LLM’s functionality, allowing interaction with the internet or other applications. They enable models like GPT to incorporate domain-specific knowledge without retraining, perform specialized tasks, and complete a series of tasks autonomously—eliminating the need for re-prompting. First, the concept of Self-refinement explores the idea of LLMs improving themselves by learning from their own outputs without human supervision, additional training data, or reinforcement learning. A complementary area of research is the study of Reflexion, where LLMs give themselves feedback about their own thinking, and reason about their internal states, which helps them deliver more accurate answers.

The voice assistants are the best NLP examples, which work through speech-to-text conversion and intent classification for classifying inputs as action or question. Smart virtual assistants could also track and remember important user information, such as daily activities. Natural Language Processing, or NLP, is a subdomain of artificial intelligence and focuses primarily on interpretation and generation of natural language. It helps machines or computers understand the meaning of words and phrases in user statements. The most prominent highlight in all the best NLP examples is the fact that machines can understand the context of the statement and emotions of the user.
