CISOL: An Open and Extensible Dataset for Table Structure Recognition in the Construction Industry

Reproducibility and replicability are critical pillars of empirical research,particularly in machine learning, where they depend not only on theavailability of models, but also on the datasets used to train and evaluatethose models. In this paper, we introduce the Construction Industry SteelOrdering List (CISOL) dataset, which was developed with a focus on transparencyto ensure reproducibility, replicability, and extensibility. CISOL provides avaluable new research resource and highlights the importance of having diversedatasets, even in niche application domains such as table extraction in civilengineering. CISOL is unique in that it contains real-world civil engineering documentsfrom industry, making it a distinctive contribution to the field. The datasetcontains more than 120,000 annotated instances in over 800 document images,positioning it as a medium-sized dataset that provides a robust foundation forTable Structure Recognition (TSR) and Table Detection (TD) tasks. Benchmarking results show that CISOL achieves 67.22 [email protected]:0.95:0.05 usingthe YOLOv8 model, outperforming the TSR-specific TATR model. This highlightsthe effectiveness of CISOL as a benchmark for advancing TSR, especially inspecialized domains.
