“…Informetric analyses on research fronts are well established (e.g., Garfield, 1994;Morris, Yen, Wu, & Asnake, 2003;Persson, 1994;Price, 1965); in addition, there have been attempts at predicting the ranking of papers and authors by analyzing research fronts (e.g., Burrell, 2003;Feitelson & Yovel, 2003;Glänzel, 1997;Glänzel & Schoepflin, 1994;Glänzel & Schubert, 1995). Furthermore, there are also examples of studies of research fields where analyses of trends have been used to predict future development of research fields (e.g., Yashin & Yashin, 2001).…”
