The study of Dirac materials, i.e. materials where the low-energy fermionic excitations behave as massless Dirac particles has been of ongoing interest for more than two decades. Such massless Dirac fermions are characterized by a linear dispersion relation with respect to the particle momentum. To identify Dirac materials in the class of 3-dimensional organic crystals we build up an organic materials database and apply data mining. The talk will be divided into three parts. At the beginning a short introduction into Dirac materials is given. Afterwards the organic materials database which is based on electronic structure calculations in the framework of density functional theory is presented. In the last part of the talk, it is explained how data mining can be used to search for organic Dirac materials.
