natural language processing

Natural language processing (NLP) takes text or speech and converts it into forms that can be used as parts of larger systems. It may be used interactively in a conversatonal user interface or voice assistant, or as part of a batch process such as information management extracting structured data from free-text documents. Traditional NLP often proceeds in a number of phases {{syntactic analysis} – ((semantic analysis}}– ((pragmatic analysis}}; but large-language models are more monolithic and some applications with limited vocabulary may be able to skip stages.
