Multimodal Named Entity Recognition

Multimodal Named Entity Recognition (MNER) aims to improve the accuracy of identifying and classifying named entities (e.g., people, places, organizations) in text by incorporating visual information from accompanying images. Current research focuses on developing unified frameworks that effectively integrate textual and visual representations, often employing techniques like contrastive learning, large language models (LLMs) for knowledge integration and reformulation of the task, and various attention mechanisms to align image regions with textual entities. These advancements are significant because they enhance the robustness and accuracy of information extraction from multimodal social media data, impacting applications such as question answering, entity linking, and knowledge graph construction.
