CMDR: Contextual Multimodal Document Retrieval

arXiv:2607.05927v1 Announce Type: cross Abstract: Multimodal document retrieval aims to retrieve relevant pages while preserving both textual and visual content from the original document. However, existing benchmarks primarily evaluate simple lexical or semantic matching, and most methods encode pages independently. Consequently, they overlook the contextual information in the document required to resolve queries that aggregate information across multiple pages. In this paper, we introduce CMDR and CMDR-Bench, a new multimodal document retrieval task and benchmark that require modeling docume

Why this matters
Why now

The proliferation of multimodal AI models and the increasing complexity of information retrieval tasks necessitate more sophisticated benchmarks beyond simple lexical matching.

Why it’s important

Improved multimodal document retrieval is critical for advanced AI applications requiring deep contextual understanding across diverse data formats, impacting research and enterprise intelligence.

What changes

The focus shifts from independent page encoding to methods that leverage contextual information within and across document pages for more accurate and comprehensive information retrieval.

Winners
  • · AI researchers focusing on multimodal understanding
