One possible way to identify this relevant nugget is to apply sentence compression techniques (McDonald, 2006;Siddharthan, 2011;Štajner et al., 2013;Filippova et al., 2015;Filippova and Strube, 2008;Narayan and Gardent, 2014;Cohn and Lapata, 2009).
all these methods have been developed for standard texts with complete sentences, and it is not clear whether they are suited to dictionary definitions.
