An Experimental Study On The Dynamic Evolution Of Core Documents

Introduction The concept of the core of documents had originally been introduced in connection of cocitation analysis (Small 1973). The term core documents has later been re-introduced in the context of bibliographic coupling (BC; see Glänzel & Czerwon, 1996) and hybrid BC and text based similarities (Glänzel & Thijs, 2011) in order to identify strongly interlinked papers that form important nodes in the network of scholarly communication. In order to study stability and dynamics of core-document sets we apply two different methods to h-index related literature in the period 2005–2013 for illustration.
