We thus concentrate on two experimental protocols-the one described by Kim et al. (2014) (referred to as Kim protocol) and the one from <cite>Kulkarni et al. (2015)</cite> (referred to as Kulkarni protocol), including close variations thereof. Kulkarni's protocol operates on all 5-grams occurring during five consecutive years (e.g., [1900] [1901] [1902] [1903] [1904] and trains models independently of each other.
