OpenBMB 提出 Trident:解决多模态检索中文本压过图像的问题

摘要

OpenBMB 发现多模态检索器在纯文本和纯图像语料上表现良好,但在图文混合语料上明显退化,并将这一现象称为 Chaos in the Text。分析显示存在系统性的模态偏好:文本常比语义对齐的图像获得更高相似度分数。

🔱 Why can irrelevant text outrank an image that actually contains the answer?

We find that multimodal retrievers can perform well on text-only and image-only corpora, yet degrade sharply when text and images are mixed.

We call this phenomenon "Chaos in the Text."

Our analysis reveals a systematic Modality Preference: text often receives higher similarity scores than semantically aligned images. We introduce Trident, which jointly trains Text / Image / Fused views with Multi-Positive View InfoNCE.

On 6 visual-document retrieval benchmarks, Trident-Qwen3VL-2B improves Mix Avg NDCG@10 from 40.12 → 73.90.
