NLP

Natural Language Processing (NLP) is a branch of AI that lets machines read, interpret, and generate human language, combining linguistics with statistical and neural techniques. On AIF-C01, NLP underpins several AWS services: Amazon Comprehend performs managed tasks like sentiment analysis, entity recognition, key-phrase extraction, and topic modeling without custom model training, while Amazon Bedrock foundation models handle open-ended text generation and summarization. A common exam trap is treating NLP and generative AI as interchangeable. NLP broadly covers understanding and analyzing language, whereas generative AI specifically produces new text. Comprehend is NLP; a Bedrock large language model doing free-form writing is generative AI built on NLP foundations.
