Technical documents in the field of materials science contain many equations. However, information such as the meanings and units of variables is often described in a non-structured manner, making cross-literature utilization difficult. In this study, equations and descriptors were automatically extracted and structured from adsorption materials papers using large language models, and the equations were represented in a numerically computable SymPy format and organized into a graph database, thereby establishing a basis for the cross-literature reference and reuse of knowledge derived from equations.
