Lexicalized vs. Delexicalized Parsing in Low-Resource Scenarios

Agnieszka Falenska, Özlem Çetinoğlu


Abstract
We present a systematic analysis of lexicalized vs. delexicalized parsing in low-resource scenarios, and propose a methodology to choose one method over another under certain conditions. We create a set of simulation experiments on 41 languages and apply our findings to 9 low-resource languages. Experimental results show that our methodology chooses the best approach in 8 out of 9 cases.
