While NLP offers numerous benefits, it also comes with challenges. One major challenge is the complexity of human language, which includes nuances like slang, sarcasm, and idioms that are difficult for machines to understand. Another challenge is the need for large amounts of high-quality data to train NLP models effectively. Additionally, there are concerns related to data privacy and security, as NLP often involves processing sensitive information. Lastly, the implementation of NLP requires significant investment in terms of time, money, and expertise.
