“…Probably one of the biggest categories of MWE-L formalisms would be those based on phrase grammars. We further divide this category into two smaller: (i) formalisms based on list-like or regexlike structures (Breidt et al, 1996;Alegria et al, 2004;Oflazer et al, 2004;Sailer and Trawiński, 2006;Spina, 2010;Quochi et al, 2012;Al-Sabbagh et al, 2014;Al-Haj et al, 2014;Walsh et al, 2019), component words are listed in the order in which they can appear and discontinuities are most often denoted by special symbols imposing constraints on the types of insertions allowed (either by limiting the number of insertions or the words which can be inserted); (ii) formalisms based on more expressive phrase grammars (CFGs, TAGs, LFGs, HPSGs, ...) (Grégoire, 2010;Przepiórkowski et al, 2017;Savary et al, 2018b;Dyvik et al, 2019), here component words are usually terminals appearing in grammar rules, and discontinuities are denoted by non-terminals.…”
