O que é Processamento de Linguagem Natural?
Processamento de Linguagem Natural (NLP) is a subfield of artificial intelligence (AI) that focuses on the interaction between computers and humans through linguagem natural. The goal of NLP is to enable machines to understand, interpret, and generate human language in a way that is both meaningful and useful.

NLP emprega várias técnicas da linguística, ciência da computação, and machine learning. Traditional methods involve rule-based systems and grammar, while modern approaches often leverage deep learning models, such as neural networks, to improve accuracy and performance.
Applications of NLP are widespread and include virtual assistants (like Siri and Alexa), chatbots for customer service, tradução de idiomas services, and tools for analyzing social media sentiment. As NLP continues to advance, it is reshaping how we interact with technology, making it more intuitive and responsive to our natural communication.
