Natural Language Processing Overview

NLU enables human-computer interaction by analyzing language versus just words. NLU is a subtopic of Natural Language Processing that uses AI to comprehend input made in the form of sentences in text or speech format. It enables computers to understand commands without the formalized syntax of computer languages and it also enables computers to communicate back to humans in their own languages.

In this article, we will delve into the world of NLU, exploring its components, processes, and applications—as well as the benefits it offers for businesses and organizations. This can be attributed to the increasing demand for advanced AI technologies that can understand and interpret human language in various industries such as customer service, healthcare, BFSI, and retail. NLU systems are widely used for applications such as virtual assistants, chatbots, voice recognition, and sentiment analysis.

What is NLG or Natural Language Generation?

But when you use an integrated system that ‘listens,’ it can share what it learns automatically- making your job much easier. In other words, when a customer asks a question, it will be the automated system that provides the answer, and all the agent has to do is choose which one is best. Manual ticketing is a tedious, inefficient process that often leads to delays, frustration, and miscommunication. This technology allows your system to understand the text within each ticket, effectively filtering and routing tasks to the appropriate expert or department. By 2025, the NLP market is expected to surpass $43 billion–a 14-fold increase from 2017.

NLU is particularly effective with homonyms – words spelled the same but with different meanings, such as ‘bank’ – meaning a financial institution – and ‘bank’ – representing a river bank, for example. Human speech is complex, so the ability to interpret context from a string of words is hugely important. This algorithmic approach uses statistical analysis of ‘training’ documents to establish rules and build its knowledge base. However, because language and grammar rules can be complex and contradictory, this algorithmic approach can sometimes produce incorrect results without human oversight and correction. Expert.ai Answers makes every step of the support process less expensive both for the customer and the support staff. Simply put, using previously gathered and analyzed information, computer programs are able to generate conclusions.

Text Analysis and Sentiment Analysis

For example, it is relatively easy for humans who speak the same language to understand each other, although mispronunciations, choice of vocabulary or phrasings may complicate this. NLU is responsible for this task of distinguishing what is meant by applying a range of processes such as text categorization, content analysis and sentiment analysis, which enables the machine to handle different inputs. Natural language generation (NLG) is the use of artificial intelligence (AI) programming to produce written or spoken narratives from a data set. NLG is related to human-to-machine and machine-to-human interaction, including computational linguistics, natural language processing (NLP) and natural language understanding (NLU). Conversational interfaces, also known as chatbots, sit on the front end of a website in order for customers to interact with a business. Because conversational interfaces are designed to emulate “human-like” conversation, natural language understanding and natural language processing play a large part in making the systems capable of doing their jobs.

• You may, for instance, use NLP to classify an email as spam, predict whether a lead is likely to convert from a text-form entry or detect the sentiment of a customer comment.
• With the NLU market projected to grow at a CAGR of over 28% between 2021 and 2026, these companies are well-positioned to capitalize on the increasing demand for advanced NLU technologies.

• Known for its conversational AI and speech recognition technology, Nuance has been serving various industries, including healthcare, automotive, and customer service.
• This allows it to select an appropriate response based on keywords it detects within the text.
• However, most word sense disambiguation models are semi-supervised models that employ both labeled and unlabeled data.
