Natural language processing (NLP) strives to bridge the gap between the complex world of human language and the structured world of machines. Coreference, the phenomenon where words or phrases refer back to previously mentioned entities, plays a crucial role in this endeavor. Understanding and resolving coreference is essential for tasks like machine translation, question answering, and sentiment analysis, as it allows machines to grasp the relationships between elements in a sentence and build a coherent understanding of the text.
