A multi-dimensional space, spanned by a set of parameters extracted from psuedo-poten-tials, Slater’s atomic orbitals, etc., is applied to investigating various chemical-bond-relatingproperties of inorganic compounds by computerized pattern recognition technique. The inves-tigations of the crystal types of intermetallic compounds and the thermodynamic behaviors ofoxide systems are shown as examples. Based on the empirical rules found, computerizedpredictions of some unknowns have come true, some of which have been confirmed by theexperiments.
