Relationship Extraction

Relationship extraction, a core task in natural language processing, aims to identify and classify relationships between entities within text or other data modalities like images. Current research focuses on improving accuracy and efficiency using various approaches, including transformer-based models, graph neural networks, and large language models, often incorporating techniques like attention mechanisms and semantic enhancement to handle complex relationships and data sparsity. These advancements are significantly impacting fields like knowledge graph construction, information retrieval, and recommendation systems by enabling more accurate and automated extraction of structured information from unstructured data sources.
