10.48550/arXiv.2603.26052A novel framework for multimodal media verification that actively bridges pixels and words using mask-aware local semantic fusion to detect sophisticated misinformation.
Abstract
As multimodal misinformation becomes more sophisticated, its detection and grounding are crucial. However, current multimodal verification methods, relying on passive holistic fusion, struggle with sophisticated misinformation. Due to 'feature dilution,' global alignments tend to average out subtle local semantic inconsistencies, effectively masking the very conflicts they are designed to find. We introduce MaLSF (Mask-aware Local Semantic Fusion), a novel framework that shifts the paradigm to active, bidirectional verification, mimicking human cognitive cross-referencing. MaLSF utilizes mask-label pairs as semantic anchors to bridge pixels and words. Its core mechanism features two innovations: 1) a Bidirectional Cross-modal Verification (BCV) module that acts as an interrogator, using parallel query streams (Text-as-Query and Image-as-Query) to explicitly pinpoint conflicts; and 2) a Hierarchical Semantic Aggregation (HSA) module that intelligently aggregates these multi-granularity conflict signals for task-specific reasoning. In addition, to extract fine-grained mask-label pairs, we introduce a set of diverse mask-label pair extraction parsers. MaLSF achieves state-of-the-art performance on both the DGM4 and multimodal fake news detection tasks. Extensive ablation studies and visualization results further verify its effectiveness and interpretability.

RESULT
ScienceToStartup currently rates this 5.0/10 on the public viability pass. MaLSF achieves state-of-the-art performance on both the DGM4 and multimodal fake news detection tasks.
WHY NOW
Multimodal AI moved forward this cycle; last verified April 2026. Public score 5.0/10.
MaLSF shifts multimodal verification from passive fusion to an active, bidirectional verification process, mimicking human cognitive cross-referencing.
This is a core contribution explicitly stated in the abstract and introduction.
partial
MaLSF utilizes mask-label pairs as semantic anchors to bridge pixels and words.
This is a key technical innovation described in the abstract and introduction.
partial
Its core mechanism features two innovations: 1) a Bidirectional Cross-modal Verification (BCV) module that acts as an interrogator, using parallel query streams (Text-as-Query and Image-as-Query) to explicitly pinpoint conflicts;
This is a specific component of the proposed method, detailed in the abstract and architecture description.
partial
and 2) a Hierarchical Semantic Aggregation (HSA) module that intelligently aggregates these multi-granularity conflict signals for task-specific reasoning.
This is another key component of the proposed method, detailed in the abstract and architecture description.
partial
MaLSF achieves state-of-the-art performance on both the DGM4 and multimodal fake news detection tasks.
This is a primary result reported in the abstract and supported by performance tables.
partial
As demonstrated in Fig. 1(c), MaLSF successfully identifies the subtle “champagne-vs-failed” conflict that eludes traditional methods.
This is a specific example illustrating the effectiveness of the method, mentioned in the introduction.
partial
However, current multimodal verification methods, relying on passive holistic fusion, struggle with sophisticated misinformation. Due to 'feature dilution,' global alignments tend to average out subtle local semantic inconsistencies, effectively masking the very conflicts they are designed to find.
This is the motivation for the proposed work, stated in the abstract and introduction.
