“…The disambiguation of authors whose names coincide and overlap in the citation indexing systems calls for methods that distinguish the contexts in which authors or individuals appear, such as cross-document co-reference resolution algorithms that use the vector space model to resolve ambiguities (Bagga & Baldwin, 1998;Gooi & Allan, 2004;Han, Giles, Zha, Li, & Tsioutsiouliklis, 2004;Wacholder, Ravin, & Choi, 1997), co-occurrence analysis and clustering techniques (Han, Zha, & Giles, 2005;Mann & Yarowsky, 2003;Pedersen, Purandare, & Kulkarni, 2005), probabilistic similarity metrics (Torvik, Weeber, Swanson, & Smalheiser, 2005), or co-citation analysis and visualization mapping algorithms through a Kohonen network (X. Lin, White, & Buzydlowski, 2003;McCain, 1990).…”
