NLP vs NLU vs. NLG: Understanding Chatbot AI

Marketers can benefit from natural language processing to learn more about their customers and use those insights to create more effective strategies. Hiring and Recruitment – By using natural language processing in hiring and recruitment, candidate searches are sped up by filtering and sifting through resumes of applicants that meet the job requirements. Natural language processing, or NLP for short, is the automatic manipulation of natural language like speech and text by software. The IBM research showed that almost half of businesses are using applications powered by NLP and one in four businesses plan to begin using NLP technology over the next 12 months. Keep reading to uncover the three goals that sentence generation thanks to natural language processing and natural language generation can help you achieve.

NLU often involves incorporating external knowledge sources, such as ontologies, knowledge graphs, or commonsense databases, to enhance understanding. The technology also utilizes semantic role labeling (SRL) to identify the roles and relationships of words or phrases in a sentence with respect to a specific predicate. NLP, with its focus on language structure and statistical patterns, enables machines to analyze, manipulate, and generate human language. It provides the foundation for tasks such as text tokenization, part-of-speech tagging, syntactic parsing, and machine translation.

Understanding syntax and semantics

Voice assistants equipped with these technologies can interpret voice commands and provide accurate and relevant responses. Sentiment analysis systems benefit from NLU’s ability to extract emotions and sentiments expressed in text, leading to more accurate sentiment classification. NLU enables machines to understand and interpret human language, while NLG allows machines to communicate back in a way that is more natural and user-friendly.

They analyze the underlying data, determine the appropriate structure and flow of the text, select suitable words and phrases, and maintain consistency throughout the generated content. By harnessing advanced algorithms, NLG systems transform data into coherent and contextually relevant text or speech. These algorithms consider factors such as grammar, syntax, and style to produce language that resembles human-generated content. Language generation is used for automated content, personalized suggestions, virtual assistants, and more.

Many companies and consumers are already using it

For machines, human language, also referred to as natural language, is how humans communicate—most often in the form of text. It comprises the majority of enterprise data and includes everything from text contained in email, to PDFs and other document types, chatbot dialog, social media, etc. An NLP chatbot is a virtual agent that understands and responds to human language messages. It, most often, uses a combination of NLU, NLG, artificial intelligence, and machine learning to convert human language into something it can understand and then generate a response that’s understandable to humans. It integrates computational linguistics, which applies rule-based language models, with sophisticated algorithms from machine learning and deep learning. This combination allows computers to process and ‘understand’ human language, whether written or spoken, capturing the essence of the speaker’s or writer’s intent.

This reduces the cost to serve with shorter calls, and improves customer feedback. 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. NLG is used for text generation in English or other languages, by a machine based on a given data input. These techniques have been shown to greatly improve the accuracy of NLP tasks, such as sentiment analysis, machine translation, and speech recognition.

• Keyword extraction, on the other hand, gives you an overview of the content of a text, as this free natural language processing model shows.
• The voice assistant uses the framework of Natural Language Processing to understand what is being said, and it uses Natural Language Generation to respond in a human-like manner.
• This transparency makes symbolic AI an appealing choice for those who want the flexibility to change the rules in their NLP model.
• The syntactic analysis involves the process of identifying the grammatical structure of a sentence.
