MMLongEmbed: Benchmarking Multimodal Embedding Models in Long-Context Scenarios
A new benchmark called MMLongEmbed has been introduced to evaluate multimodal embedding models (MEMs) in long-context scenarios. The benchmark includes four retrieval tasks across text, document, and video modalities, designed to assess how effectively models comprehend and represent lengthy multimodal inputs. Initial evaluations reveal that current MEMs tend to rely on superficial feature matching and struggle with deep semantic and structural dependencies, with performance degradation varying based on context length and information placement.
