QGCMA: A Framework for Knowledge-Based Visual Question Answering
This paper introduces QGCMA, a novel framework for Knowledge-Based Visual Question Answering (KB-VQA) that addresses challenges in integrating external knowledge and aligning multi-modal features. It proposes three key innovations: Question-Guided Attention (QGA) for dynamic focus on relevant visual regions and knowledge entities, Cross-Modal Alignment (CMA) using contrastive learning for semantic consistency across visual, textual, and knowledge modalities, and Dynamic Knowledge Integration (DKI) for adaptive knowledge fusion from external graph structures. Experimental evaluations on OK-VQA and VQA v2 benchmarks demonstrate its superior performance over existing state-of-the-art methods, particularly in handling complex reasoning tasks requiring compositional inference over structured knowledge.
Executive Impact
QGCMA significantly advances KB-VQA by intelligently integrating question-guided attention, cross-modal alignment, and dynamic knowledge fusion to enhance reasoning capacity and achieve state-of-the-art performance on knowledge-intensive VQA tasks.

Question-Guided Attention (QGA)
The QGA mechanism adaptively steers the model's focus towards visual regions and knowledge entities semantically congruent with the query. This ensures contextually relevant information is prioritized, enhancing the model's ability to capture pertinent visual and knowledge cues.

Cross-Modal Alignment (CMA)
The CMA module employs a contrastive learning strategy to enforce precise alignment across visual, textual, and knowledge modalities. This effectively mitigates detrimental effects of spurious correlations by enhancing semantic consistency among heterogeneous data sources, improving multi-modal feature integration.
-3.78%
Performance drop without CMA, highlighting its critical role in semantic consistency.
CMA in Action: Semantic Consistency
In an image showing vegetables and a knife, the query "Is there something to cut the vegetables with?" requires the model to semantically link "knife" (visual feature) with "cutting tool" (textual query concept). Without CMA, the model might fail to establish this connection, leading to an incorrect answer or misinterpretation of the image context. CMA's contrastive learning ensures that visual representations of a knife are aligned with textual representations of "cutting tool," enabling correct inference.
Dynamic Knowledge Integration (DKI)
The DKI component empowers the model to dynamically select and fuse knowledge information from external graph structures (e.g., ConceptNet). This functionality significantly augments the model's reasoning capacity, enabling it to handle questions that necessitate compositional inference over structured knowledge.
-8.53%
Largest performance drop (-8.53%) when DKI is removed, emphasizing its crucial role in knowledge-intensive tasks.
DKI in Action: Answering Knowledge-Intensive Queries
Consider the question "What is the capital of the country where the building is located?" when shown an image of the Eiffel Tower. DKI enables the model to: 1. Recognize the Eiffel Tower (visual). 2. Query external knowledge (ConceptNet) for "Eiffel Tower is in France" and "capital of France is Paris." 3. Dynamically fuse this knowledge with visual and textual information to infer the answer "Paris." Without DKI, the model would be unable to access or integrate the necessary external facts, resulting in a failure to answer correctly.
