We introduce the data sciences of our large-scale dataset on the experimental thermoelectric properties, collected in Starrydata web system. By using this dataset, we analyzed the trends in thermoelectric properties of PbTe-type materials. We also carried out machine learning of over 10,000 samples to predict thermoelectric properties from chemical compositions.
