“…It can provide crucial, although shallow, semantic information for tasks such as question answering (Abujabal et al, 2018;Blanco-Fernández et al, 2020), topic disambiguation (Fernández, N. et al 2012) or detection (Krasnashchok et al, 2018;Lo et al, 2017, Al-Nabki et al, 2019 and revealment of elements relationships (Sarica et al, 2020;Amal et al, 2019). Furthermore, NER has proved to be effective in broader applications, such as user profiling (Nicoletti et al, 2013) and ontology development on unconventional domains (Oliva et al, 2019;Rodrigues et al, 2019). Anyway, since NER is a classification task, for using the most advanced approach in terms of accuracy (corpus-based NER uses deep neural networks) (Devlin et al, 2018), a training set is needed, i.e.…”
