The vast amount of world knowledge available in Wikipedia has been shown to benefit many types of text processing tasks, such as coreference resolution (Ponzetto and Strube, 2006;Haghighi and Klein, 2009;Bryl et al., 2010;Rahman and Ng, 2011), information retrieval (Milne, 2007;Li et al., 2007;Potthast et al., 2008;Cimiano et al., 2009), or question answering (Ahn et al., 2004;Kaisser, 2008;Ferrucci et al., 2010).
the user contributed link structure of Wikipedia has been shown to provide useful supervision for training named entity disambiguation (Bunescu and Pasca, 2006;Cucerzan, 2007) and word sense disambiguation (Mihalcea, 2007;Ponzetto and Navigli, 2010) systems.
