CODAAConven*onalOrthography

forDialectalArabic•  Developed for computational processing purposes

(Habash et al, 2012) •  Objectives

–  CODA covers all Arabic dialects in principle –  CODA minimizes differences in choices –  CODA is easy to learn and produce consistently –  CODA is intuitive to readers unfamiliar with it –  CODA uses Arabic script

•  Current manuals for Egyptian, Tunisian, Levantine, Algerian, and Gulf
