King Saud University researchers built AAEE, one of the first automated essay scorers for Arabic, modeled on Saudi schools' official rubric. Tested on 350 real student essays across eight topics, it reached 90% accuracy and a 0.756 correlation with human graders.
Researchers in the Department of Computer Science, College of Computer & Information Sciences at King Saud University built AAEE, one of the first systems to automatically score Arabic-language essays, addressing a gap left by automated essay scoring (AES) research that has mostly focused on English.
Automatically score and give feedback on Arabic-language essays written by Saudi intermediate and secondary students, modeled on the official school rubric criteria of language proficiency, essay structure and content relevance.
AAEE combines Latent Semantic Analysis with Rhetorical Structure Theory to assess both lexical/grammatical quality and the coherence of an essay's argument structure; it was evaluated against a purpose-built corpus of 350 essays across eight topics, independently scored by human instructors as ground truth.
AAEE reached 90% accuracy and a 0.756 correlation with human graders; a later 2023 study using the same corpus found newer machine-learning approaches, including Random Forest models, could reach a 0.913 correlation, surpassing AAEE's benchmark.
AAEE remains a research-stage system, validated on a compiled essay corpus rather than deployed in live Saudi classrooms or national exams, but it established an important early benchmark for Arabic automated essay scoring.
