• receive, at the client system, a first query inputted by the first user, wherein the first query comprises one or more n-grams;
• select, based on the first query, one or more of the authorized set of ideograms;
• present, at the client system, the one or more selected ideograms, wherein the ideograms are presented in ranked order, each ideogram being selectable by the first user;
