Natural Language Processing (NLP) is a branch of AI that enables computers to understand and respond to human language.
NLP is important as it bridges the gap between humans and machines, transforming industries like healthcare, e-commerce, customer support, and education.
NLP is used in virtual assistants, sentiment analysis, language translation, document summarization, and various other applications in different industries.
Building NLP applications requires addressing challenges like data preprocessing, model training and evaluation, handling complex sentence structures, security concerns, and resource-intensive tasks.
