“…-Many works go further into some specific domains, such as Sci-Tech compound entity recognition (Yan et al 2016), biomedical named entity recognition (Song et al 2018), entity extraction from clinical records (Alicante et al 2016;Boytcheva 2018;Henriksson et al 2015), chemical named entity recognition (Swain and Cole 2016; Zhang et al 2016), educational term extraction (Conde et al 2016), cybersecurity concepts extraction (Xiao 2017), Drug Name Recognition (Liu et al 2015b), medical named entity recognition (He and Kayaalp 2008;Kavuluru et al 2013;Skeppstedt 2014), and so forth. -In addition to English, unsupervised Named Entity Recognition has been studied in other languages, including Chinese (Jia et al 2018), Spanish (Copara et al 2016), French (Mosallam et al 2014), Italian (Alicante et al 2016), and Russian (Ivanitskiy et al 2016), as well as crosslingual (Abdel Hady et al 2014), even including a dead language like Sumerian (Liu et al 2015a).…”
