Arabic NLP models find character iconicity largely arbitrary

A new research paper explores the iconicity versus arbitrariness of Arabic script for natural language processing (NLP). The study found that random remappings of Arabic characters, while maintaining the same reduced set of base shapes, achieve competitive NLP performance. This suggests that models rely more on distributional structure than on the visual iconicity of letter forms, indicating that Arabic character form-function relationships are largely arbitrary from an NLP perspective. The findings could lead to reduced vocabulary sizes, lower out-of-vocabulary rates, and decreased training costs for Arabic NLP models. AI

IMPACT Suggests that arbitrary character remappings can improve efficiency and reduce costs in Arabic NLP models.
