The data of the article“A Domain Expert-Guided Knowledge Mining Framework for Exploring Materials Structure-Property Relationships”

The data that support the findings of this study are available from the corresponding author upon reasonable request. Since the raw dataset cannot be directly published due to copyright restrictions, this document details the standardized pipeline for corpus annotation and dataset construction using the Baidu EasyData platform.

This protocol ensures the transparency, rigor, and reproducibility of the high-quality data annotation and knowledge mining process. To demonstrate the annotation schema and data structure, a representative subset of the data, comprising 100 entity annotations and 100 relation annotations, is presented in two tables: entity_extraction-20260812 and entity_relationship_extraction-20260812.
