To develop a specialized, automated model that accurately extracts structured data from visual scatter plots published in materials science literature.
Engineered DataEX-Sc using five coordinated modules governed by dual optimization loops, coupling rule-based computer vision methods with multimodal large language models (MLLMs).
Implemented an outer co-evolution loop where image-text pairs fine-tune MLLMs, which subsequently optimize DataEX-Sc's algorithms and parameters.
Evaluated extraction performance against existing fully automatic and semi-automatic plot-parsing tools across varied error thresholds.
Achieved an absolute F1 gain greater than 0.23 compared to existing fully automatic tools at a relative error threshold of 0.02.
Improved data extraction efficiency by 80% compared with existing semi-automatic tools.
