Understanding natural language processing

Natural language processing (NLP) is a field that uses computer science techniques to understand and work with human languages. NLP involves preprocessing text through steps like normalization, tokenization, removing stop words, stemming and lemmatization. It represents text numerically using methods like bag-of-words and word embeddings. Sequence modeling with RNNs, GRUs and LSTMs is used for tasks like machine translation and conversational AI. NLP has many applications including machine translation, conversational assistants and analyzing large amounts of text data.
