Subject: Natural Language Processing (NLP) Through my work in implementing AI chatbots and taking the Natural Language Processing (NLP) course, I realized that since the introduction of the "Attention Is All You Need" paper and the breakthrough models like "Transformer" , "BERT" , and "GPT-2" , there has been a significant increase in both corporate and academic interest in dialog systems such as AI chatbots and customer support services , with NLP technologies at their core. This shift can be attributed to the advancements in NLP technologies , which have reached a point where natural language services are widely accepted without significant resistance . In this context, I want to explore what Natural Language Processing (NLP) is, why the interest in it has grown rapidly , and what technologies have made this possible . Additionally, I will present the requirements and methods for developing AI services based on NLP technology . Approach...
