- Natural Language Processing (NLP) concentrates on understanding and processing human language.
- NLG is commonly used in chatbots, content generation, and report writing.
- NLP powers applications like sentiment analysis, language translation, and speech recognition.
Natural Language Generation (NLG) involves the generation of coherent, meaningful language by machines. It aims to create human-like text in multiple languages, imitating the way humans communicate through speech and writing. NLG algorithms analyze data and convert it into natural language text, enabling systems to generate content autonomously.
*NLG is a powerful tool that allows machines to write articles, reports, and even stories, providing valuable assistance to various industries.*
Natural Language Processing (NLP)
Natural Language Processing (NLP), on the other hand, focuses on interpreting and understanding human language. It involves the interaction between computers and humans through language, enabling machines to derive meaning from text or speech input. NLP techniques enhance communication between humans and machines, enabling applications that can understand, interpret sentiment, translate languages, and more.
*NLP has revolutionized the way we interact with technology, making it possible for machines to understand and process human language.*
