They have been used for a wide variety of tasks, such as textual entailment (Berant et al., 2011), question answering (Fader et al., 2014), and knowledge base population (Angeli et al., 2015).
perhaps due to limited data, existing methods use semisupervised approaches (Banko et al., 2007;Wu and Weld, 2010), or rule-based algorithms (Fader et al., 2011;Mausam et al., 2012;Del Corro and Gemulla, 2013).
