What are Named Entities?
Named entities are distinct and specific items within a text that represent real-world objects or concepts. In the context of Natural Language Processing (NLP), named entities typically refer to proper nouns, which include names of people, organizations, locations, dates, and other identifiable elements. The significance of named entities lies in their ability to provide contextual meaning and enhance information retrieval.

Named Entity Recognition (NER)
Named Entity Recognition is a subtask of NLP that focuses on identifying and classifying named entities within a given text. Through algorithms and models, NER systems can automatically recognize named entities, streamlining data analysis and facilitating various applications, such as information extraction, sentiment analysis, and question answering.
Importance in AI
The identification of named entities is crucial in Artificial Intelligence as it helps machines understand and process human language more effectively. By recognizing these entities, AI systems can enhance their understanding of context and intent, leading to improved communication and interaction experiences.
