The article is a continuation of efforts for the formulation of criteria and measures for scientific work in architecture, which is in Slovenia confonted with accelerated enforcement of quantitative indicators of excellence of scientific research work. It searches for those data layers in the "ISI" databases, which point out specifics of the architectural profession worldwide and whose superficial acknowledgment is used by the productively most successful sciences in Slovenia to argument their scientific excellence. Special emphasis is given to the relation between architecture and the entire scientific production in selected cultural fields within the referential data system. It contributes to argtunentation of the need for quality definitions of influence of architecture's scientific level that should complement the favoured "impact factor", which is better suited for disciplines that figure in the selected data systems with highest productivity. In conclusion possibilities for such definition of scientific influence of architecture are pointed out.
