We obtain HRCs by considering the title of each marked-up item as a hypernym candidate, and titles of its all subordinate marked-up items as its hyponym candidates; for example, we extract 'England', 'France', 'Wedgwood', 'Lipton', and 'Fauchon' as hyponym candidates of 'Common tea brands' from the hierarchical structure in Figure 1 . Note that <cite>Sumida and Torisawa (2008)</cite> extracted HRCs by regarding the title of each marked-up item as a hypernym candidate and titles of its direct subordinate marked-up items as its hyponyms; for example, they extracted only 'England' and 'France' as hyponym candidates of 'Common tea brands' from the hierarchical structure in Figure 1 .
