Spatial Priming Outperforms Semantic Prompting: A Grid-Based Approach to Improving LLM Accuracy on Chart Data Extraction
A new grid-based method called "spatial priming" has been shown to improve the accuracy of large language models (LLMs) in extracting data from charts. This technique outperforms traditional "semantic prompting" methods. The research was presented at the 7th International Conference on Control Systems, Mathematical Modeling, Automation, and Energy Efficiency (SUMMA) in Lipetsk, Russia.
A recent study introduces an innovative grid-based technique, termed "spatial priming," designed to enhance the accuracy of large language models (LLMs) in extracting data from charts. This new method represents a significant advancement over conventional "semantic prompting" approaches. It focuses on how LLMs process visual information presented in a structured grid format, leading to more precise data interpretation.
The research, titled "Spatial Priming Outperforms Semantic Prompting: A Grid-Based Approach to Improving LLM Accuracy on Chart Data Extraction," was authored by Andrei Lazarev and his colleagues. The findings indicate a clear benefit of spatial organization in guiding LLMs to better understand and interpret chart data.
The paper was presented at the 7th International Conference on Control Systems, Mathematical Modeling, Automation and Energy Efficiency (SUMMA), held in Lipetsk, Russian Federation, in 2025. This conference serves as a key platform for disseminating advancements in areas related to control systems, automation, and energy efficiency, underscoring the relevance of this research to the broader scientific community.
Further details and the full text of the paper are available through arXiv, with a DOI confirming its formal publication. The work contributes to the ongoing efforts to improve the practical applications of LLMs, particularly in fields requiring accurate data extraction and analysis from various visual representations.
