In order to incorporate the structural features of organic ligands into investigation, this paper leverages graph kernels: the structural features should be represented faithfully by graphs of atoms, and graph kernels evaluate the similarity between graphs. Furthermore, we define a unified kernel to evaluate the similarity between MOFs, which is a weighted sum of an RBF kernel to evaluate the similarity of metals and the said graph kernel. With this unified kernel and the support vector machine classification algorithm, we develop a model that predicts whether a given combination of a metal and an organic ligand can result in an MOF with high specific surface area.
