A fundamental problem in computational linguistics is the paucity of manually annotated data, such as part-of-speech tagged sentences, treebanks, and logical forms, which exist only for few languages (Ide et al., 2010).
as mentioned earlier in Section 2, constructing a pseudoword by combining a random set of unambiguous words, as was done in these early works, can not model systematic polysemy (Gaustad, 2001;Nakov and Hearst, 2003), since different senses of a real ambiguous word, unless it is homonymous, share some semantic or pragmatic relation.
