Entity Linking

Entity linking (EL) is the task of connecting textual mentions of entities (e.g., people, places, organizations) to their corresponding entries in a knowledge base. Current research emphasizes improving EL's accuracy and efficiency across diverse data types (text, images, tables), focusing on model architectures like retriever-reader systems and large language models (LLMs), often incorporating techniques such as ensemble learning and data augmentation to handle challenges like limited training data and ambiguous mentions. The advancements in EL are crucial for building robust knowledge graphs, powering applications in various fields including healthcare, cybersecurity, and scientific literature analysis, ultimately facilitating more effective information extraction and knowledge discovery.
