We have developed a web system named Starrydata for materials informatics of experimental data. By using this dataset, we investigated the trends in thermoelectric properties across the samples of thermoelectric materials. We classified the samples into the material families. Each material family showed different gradients a and the y-intercepts lnσ₀ in the inverse Jonker plot, which have Seebeck coefficient S along the x-axis, and the logarithm of electrical conductivity lnσ along the y-axis.
