NLP vs NLU vs. NLG: the differences between three natural language processing concepts

Natural Language Processing (NLP) and Natural Language Understanding (NLU) are two interdependent technologies that work together to make sense of language. NLP technologies use algorithms to identify components of spoken and written language, such as words, phrases, and punctuation. NLU, on the other hand, is used to make sense of the identified components and interpret the meaning behind them.

At its core, NLP is about teaching computers to understand and process human language. This can involve everything from simple tasks like identifying parts of speech in a sentence to more complex tasks like sentiment analysis and machine translation. In summary, NLP is the overarching practice of understanding text and spoken words, with NLU and NLG as subsets of NLP. Each performs a separate function for contact centers, but when combined they can be used to perform syntactic and semantic analysis of text and speech to extract the meaning of the sentence and summarization. Using NLU, AI systems can precisely define the intent of a given user, no matter how they say it.

What is NLP?

In this context, is often used as a synonym is Natural Language Understanding (NLU).

Furthermore, based on specific use cases, we will investigate the scenarios in which favoring one skill over the other becomes more profitable for organizations. This research will provide you with the insights you need to determine which AI solutions are most suited to your organization’s specific needs. NLP, with its ability to identify and manipulate the structure of language, is indeed a powerful tool. Consider a scenario in which a group of interns is methodically processing a large volume of sensitive documents within an insurance business, law firm, or hospital. Their critical role is to process these documents correctly, ensuring that no sensitive information is accidentally shared. Businesses like restaurants, hotels, and retail stores use tickets for customers to report problems with services or products they’ve purchased.

Improvements in computing and machine learning have increased the power and capabilities of NLU over the past decade. We can expect over the next few years for NLU to become even more powerful and more integrated into software. Technology continues to advance and contribute to various domains, enhancing human-computer interaction and enabling machines to comprehend and process language inputs more effectively.

Deep learning helps the computer learn more about your use of language by looking at previous questions and the way you responded to the results. It all starts when NLP turns unstructured data into structured data to be analyzed with NLU. Now, if you think about where NLG fits in when NLP and NLU are in the frame, it comes out as a different topic itself, but works closely with these in several applications. For example, consider an AI chatbot — It either performs some action in return for an input text (which involves NLP and NLU) or generates an answer for a given question (which involves NLP, NLU and NLG). In the transportation industry, NLU and NLP are being used to automate processes and reduce traffic congestion.

The model finalized using neural networks is capable of determining whether X belongs to class Y, class Z, or any other class. The main difference between them is that NLP deals with language structure, while NLU deals with the meaning of language. Once an intent has been determined, the next step is identifying the sentences’ entities. For example, if someone says, “I went to school today,” then the entity would likely be “school” since it’s the only thing that could have gone anywhere. Natural Language Generation (NLG) enables computers to generate written or spoken language. TS2 SPACE provides telecommunications services by using the global satellite constellations.
