AI translates 5,000-year-old cuneiform tablets into English | A new technology meets old languages.

Abstract

Cuneiform is one of the earliest writing systems in recorded human history (ca. 3,400 BCE–75 CE). Hundreds of thousands of such texts were found over the last two centuries, most of which are written in Sumerian and Akkadian. We show the high potential in assisting scholars and interested laypeople alike, by using natural language processing (NLP) methods such as convolutional neural networks (CNN), to automatically translate Akkadian from cuneiform Unicode glyphs directly to English (C2E) and from transliteration to English (T2E). We show that high-quality translations can be obtained when translating directly from cuneiform to English, as we get 36.52 and 37.47 Best Bilingual Evaluation Understudy 4 (BLEU4) scores for C2E and T2E, respectively. For C2E, our model is better than the translation memory baseline in 9.43, and for T2E, the difference is even higher and stands at 13.96. The model achieves best results in short- and medium-length sentences (c. 118 or less characters). As the number of digitized texts grows, the model can be improved by further training as part of a human-in-the-loop system which corrects the results.

Significance Statement

Hundreds of thousands of clay tablets inscribed in the cuneiform script document the political, social, economic, and scientific history of ancient Mesopotamia. Yet, most of these documents remain untranslated and inaccessible due to their sheer number and limited quantity of experts able to read them. This paper presents a state of the art neural machine translation model for the automatic translation of Akkadian texts into English, from Unicode cuneiform glyphs and from transliterations of the cuneiform signs, achieving 36.52 and 37.47 Best Bilingual Evaluation Understudy 4 (BLEU4) scores, respectively. It is particularly effective in maintaining the style of the text genre in the translation. This is another major step toward the preservation and dissemination of the cultural heritage of ancient Mesopotamia.
