Introduction
Relation extraction is a critical task in natural language processing and information extraction that involves identifying and extracting relationships between entities mentioned in text. This process plays a crucial role in knowledge base population, which aims to automatically populate knowledge bases with structured information extracted from unstructured text. By extracting relations between entities, knowledge bases can be enriched with valuable information that can be utilized in various applications, such as question answering systems, information retrieval, and data analysis.
