Attribute Extraction

TL;DR for operators When a multimodal model cannot reliably recover product details from video, the first engineering question should not automatically be how to make it reason harder. In a controlled seven-category ablation, retrieving visually similar products and their known attributes raises average micro-F1 from 33.4 to 48.3. Adding interleaved chain-of-thought without retrieval moves the score only to 33.5. The strongest standalone lever in this experiment is better evidence. ...

TL;DR for operators Catalog teams often need more labeled examples before an attribute extractor works reliably in a new category or marketplace. Producing additional product-like text is not the difficult part. The training record has to change the intended attribute while leaving unrelated product information coherent. Negri, Martínez Gómez, Balanya, and Rajaram test a controlled generation pipeline built around that requirement.1 In their downstream experiment, synthetic-only training reached 60.48% attribute-extraction accuracy, almost identical to 60.79% for original-only training. But the best tested configuration was 75% original + 25% synthetic, at 68.82%. Accuracy declined as the synthetic share rose to 50% and 75%. ...
