The authors created AlphaOracle, a computer tool inspired by how experts study ancient Chinese oracle bone script (OBS) to help decode thousands of undeciphered characters. Their system breaks down the process into steps that analyze shapes, use historical context, and check meanings against old texts, producing clear explanations for each guess. Testing showed AlphaOracle's results matched experts' closely and helped specialists work faster. It also gave new insights about a specific character linked to ancient Chinese clans. The authors suggest their approach could help with other hard-to-read ancient writings too.

Abstract
Approximately 3,000 of the 4,500 oracle bone script (OBS) characters remain undeciphered due to fragmentary inscriptions and sparse evidence. Current AI approaches fail to replicate expert workflows that integrate form analysis, contextual semantics, and philological reasoning. We introduce AlphaOracle, a human-workflow-inspired framework that systematizes OBS decipherment using the largest digitized corpus to date. Its multi-stage pipeline comprises: (i) rubbing parsing; (ii) radical-based morphological analysis with diachronic modeling; (iii) contextual retrieval with semantic alignment; and (iv) philological validation against classical sources. Each stage generates explicit, confidence-weighted evidence chains, culminating in interpretable reports for scholarly verification. Across multiple test characters, AlphaOracle's readings strongly agreed with expert interpretations. In a study of 86 domain specialists, it reduced analysis time by 64% and 79% of participants rated it highly useful. Notably, AlphaOracle resolves the character "Lao" as a toponymic or clan designation, offering concrete revisions to Shang administrative and social interpretations. These results suggest that computational methods aligned with philological practice can facilitate OBS research and provide a conceptual reference for studies of other undeciphered scripts.
