ABSTRACT=<p>A smart physical-parameter-based system identification (SI) method has been proposed in the previous paper (Ikeda et al., <xref ref-type="bibr" rid="B4">2014a</xref>). This method deals with time-variant non-parametric identification of natural frequencies and modal damping ratios using Auto-Regressive eXogenous (ARX) models and has been applied to high-rise buildings during the 2011 off the Pacific coast of Tohoku earthquake. In this perspective article, the current state of knowledge in this class of SI methods is explained briefly, and the reliability of this smart method is discussed through the comparison with the result by a more confident technique.</p>
