What NLP, NLU, and NLG Mean, and How They Help With Running Your Contact Center

Each plays a unique role at various stages of a conversation between a human and a machine. Generally, computer-generated content lacks the fluidity, emotion and personality that makes human-generated content interesting and engaging. However, NLG can be used with NLP to produce humanlike text in a way that emulates a human writer.

John Ball, cognitive scientist and inventor of Patom Theory, supports this assessment. Natural language processing has made inroads for applications to support human productivity in service and ecommerce, but this has largely been made possible by narrowing the scope of the application. There are thousands of ways to request something in a human language that still defies conventional natural language processing.

How does natural language understanding work?

The aim of using NLU training data is to prepare an NLU system to handle real instances of human speech. For example, a computer can use NLG to automatically generate news articles based on data about an event. It could also produce sales letters about specific products based on their attributes. At Observe.AI, we are combining the power of post-call interaction AI and live call guidance through real-time AI to provide an end-to-end conversation Intelligence platform for improving agent performance.

In conclusion, I hope now you have a better understanding of the key differences between NLU and NLP.

In the second example, ‘How’ has little to no value and it understands that the user’s need to make changes to their account is the essence of the question. First, it understands that “boat” is something the customer wants to know more about, but it’s too vague. Even though the second response is very limited, it’s still able to remember the previous input and understands that the customer is probably interested in purchasing a boat and provides relevant information on boat loans. How much can it actually understand what a difficult user says, and what can be done to keep the conversation going? These are some of the questions every company should ask before deciding on how to automate customer interactions.

Data Engineering

NLU is branch of natural language processing (NLP), which helps computers understand and interpret human language by breaking down the elemental pieces of speech. While speech recognition captures spoken language in real-time, transcribes it, and returns text, NLU goes beyond recognition to determine a user’s intent. Speech recognition is powered by statistical machine learning methods which add numeric structure to large datasets. In NLU, machine learning models improve over time as they learn to recognize syntax, context, language patterns, unique definitions, sentiment, and intent. NLU is a branch of artificial intelligence that deals with the understanding of human language by computers. NLU algorithms are used to process and interpret human language in order to extract meaning from it.

It’s aim is to make computers interpret natural human language in order to understand it and take appropriate actions based on what they have learned about it. NLU goes beyond the basic processing of language and is meant to comprehend and extract meaning from text or speech. As a result, NLU  deals with more advanced tasks like semantic analysis, coreference resolution, and intent recognition. A subfield of artificial intelligence and linguistics, NLP provides the advanced language analysis and processing that allows computers to make this unstructured human language data readable by machines. It can use many different methods to accomplish this, from tokenization, lemmatization, machine translation and natural language understanding.

NLP models can determine text sentiment—positive, negative, or neutral—using several methods. This analysis helps analyze public opinion, client feedback, social media sentiments, and other textual communication. Understanding semantics requires context, inference, and word relationships. NER systems scan input text and detect named entity words and phrases using various algorithms.

With FAQ chatbots, businesses can reduce their customer care workload (see Figure 5). As a result, they do not require both excellent NLU skills and intent recognition. Despite this, the neural symbolic approach shows promise for creating systems that can understand human language. Automated reasoning is a powerful tool that can help machines understand human language’s meaning. The neural symbolic approach combines these two types of AI to create a system that can reason about human language. The neural part of the system is used to understand the meaning of words and phrases, while the symbolic part is used to reason about the relationships between them.

Natural language understanding can help speed up the document review process while ensuring accuracy. With NLU, you can extract essential information from any document quickly and easily, giving you the data you need to make fast business decisions. With the advent of voice-controlled technologies like Google Home, consumers are now accustomed to getting unique replies to their individual queries; for example, one-fifth of all Google searches are voice-based.

Natural language understanding is built atop machine learning

Our brains work hard to understand speech and written text, helping us make sense of the world. Natural language generation is the process of turning computer-readable data into human-readable text. Both technologies are widely used across different industries and continue expanding. Already applied in healthcare, education, marketing, advertising, software development, and finance, they actively permeate the human resources field. For example, for HR specialists seeking to hire Node.js developers, the tech can help optimize the search process to narrow down the choice to candidates with appropriate skills and programming language knowledge.

• NLU techniques such as sentiment analysis and sarcasm detection allow machines to decipher the true meaning of a sentence, even when it is obscured by idiomatic expressions or ambiguous phrasing.
• Both NLP and NLU are related but distinct fields within artificial intelligence that deal with the ability of computers to process and understand human language.

An NLU system capable of understanding the text within each ticket can properly filter and route them to the right expert or department. Because the NLU software understands what the actual request is, it can enable a response from the relevant person or team at a faster speed. The system can provide both customers and employees with reliable information in a timely manner. Contrast this with Natural Language Processing (NLP), a broader domain that encompasses a range of tasks involving human language and computation. While NLU is concerned with comprehension, NLP covers the entire gamut, from tokenizing sentences (breaking them down into individual words or phrases) to generating new text.

This technology brings us closer to a future where machines can truly understand and interact with us on a deeper level. NLU is the ability of a machine to understand and process the meaning of speech or text presented in a natural language, that is, the capability to make sense of natural language. To interpret a text and understand its meaning, NLU must first learn its context, semantics, sentiment, intent, and syntax.

GPT-2 is a well-known autocomplete model that has been used to produce essays, song lyrics, and much more. And also the intents and entity change based on the previous chats check out below. Read on to understand what NLP is and how it is making a difference in conversational space. False positives arise when a customer asks something that the system should know but hasn’t learned yet. Conversational AI can recognize pertinent segments of a discussion and provide help using its current knowledge, while also recognizing its limitations.

By detecting these anomalies, NLU can help protect users from malicious phishing attempts. Natural language understanding (NLU) can help improve the accuracy and efficiency of cybersecurity systems by automatically recognizing patterns in languages, such as slang or dialects, to categorize potential threats. Natural Language Understanding enables machines to understand a set of text by working to understand the language of the text.

Natural language understanding is complicated, and seems like magic, because natural language is complicated. A clear example of this is the sentence “the trophy would not fit in the brown suitcase because it was too big.” You probably understood immediately what was too big, but this is really difficult for a computer. These examples are a small percentage of all the uses for natural language understanding. Anything you can think of where you could benefit from understanding what natural language is communicating is likely a domain for NLU.

• As a result, NLU  deals with more advanced tasks like semantic analysis, coreference resolution, and intent recognition.
• Accenture reports that 91% of consumers say they are more likely to shop with companies that provide offers and recommendations that are relevant to them specifically.
• IVR systems allow you to handle customer queries and complaints on a 24/7 basis without having to hire extra staff or pay your current staff for any overtime hours.
• These three terms are often used interchangeably but that’s not completely accurate.

This enables machines to produce more accurate and appropriate responses during interactions. As humans, we can identify such underlying similarities almost effortlessly and respond accordingly. But this is a problem for machines—any algorithm will need the input to be in a set format, and these three sentences vary in their structure and format. And if we decide to code rules for each and every combination of words in any natural language to help a machine understand, then things will get very complicated very quickly. When your customer inputs a query, the chatbot may have a set amount of responses to common questions or phrases, and choose the best one accordingly.

Natural language understanding can positively impact customer experience by making it easier for customers to interact with computer applications. For example, NLU can be used to create chatbots that can simulate human conversation. These chatbots can answer customer questions, provide customer support, or make recommendations. NLU also enables the development of conversational agents and virtual assistants, which rely on natural language input to carry out simple tasks, answer common questions, and provide assistance to customers.
