An efficient Trie for binding (and movement)
Cristiano Chesi · Accademia University Press eBooks · 2018
Non-local dependencies connecting distant structural chunks are often modeled using (LIFO) memory buffers (see Chesi 2012 for a review). Other solutions (e.g. slash features in HPSG, Pollard & Sag 1994) are not directly usable both in parsing and in generation algorithms without undermining an incremental left-right processing assumption. Memory buffers are however empirically limited and psycholinguistically invalid (Nairne 2002). Here I propose to adopt Trie memories instead of stacks. This leads to simpler and more transparent solutions for establishing non-local dependencies both for wh- argumental configurations and for anaphoric pronominal coreference.
