Intro to Linguistics
Named entity recognition (NER) is a subtask of natural language processing that involves identifying and classifying key entities in text, such as names of people, organizations, locations, dates, and other specific information. It plays a crucial role in extracting meaningful data from unstructured text, enabling machines to understand the context and significance of words within a sentence. NER is fundamental for applications like information retrieval, question answering, and text summarization, making it essential for leveraging machine learning techniques in language analysis.
