    • Exploiting index pruning methods for clustering XML collections 

      Altıngövde, İsmail Şengör; Atılgan, Duygu; Ulusoy, Özgür (Springer, Berlin, Heidelberg, 2010)
      In this paper, we first employ the well known Cover-Coefficient Based Clustering Methodology (C3M) for clustering XML documents. Next, we apply index pruning techniques from the literature to reduce the size of the document ...
