We include a set of basic features inspired by<cite> Eskander et al. (2013)</cite> in their CEC system and additional features for further improvement. Basic features We use a set of nine basic features: the given character, the preceding and following two characters, and the first two and last two characters in the word. These are the same features used by CEC, except that CEC does not include characters beyond the word boundary, while we consider space characters as well as characters from the previous and next words.
