This paper presents a spell checker and correction tool specifically designed for Wolof, an under-represented spoken language in Africa. The proposed spell checker leverages a combination of a trie data structure, dynamic programming, and the weighted Levenshtein distance to generate suggestions for misspelled words. We created novel linguistic resources for Wolof, such as a lexicon and a corpus of misspelled words, using a semi-automatic approach that combines manual and automatic annotation methods. Despite the limited data available for the Wolof language, the spell checker’s performance showed a predictive accuracy of 98.31% and a suggestion accuracy of 93.33%.Our primary focus remains the revitalization and preservation of Wolof as an Indigenous and spoken language in Africa, providing our efforts to develop novel linguistic resources. This work represents a valuable contribution to the growth of computational tools and resources for the Wolof language and provides a strong foundation for future studies in the automatic spell checking and correction field.

ABSTRACT The thermal fatigue cracking of asphalt concrete waterproofing layer (ACWL) in high-speed railway is mainly caused by the daily reduced temperature effect. In this study, numerical and experimental investigations on this effect were respectively conducted through the determination of surface temperature field, finite element modelling (FEM), and experiments using the customized overlay test (OT). The results indicated the thermal condition in Northern China was more severe for ACWL compared with that of other regions. The stress concentration effect on ACWL surface was mainly attributed to the temperature variation, average temperature, and viscoelastic behaviour of asphalt concrete. In addition, the OT results indicated the internal damage might happen in ACWL without obvious surface feature. Finally, the OT was in consistent with FEM analysis regarding internal stress distribution and fatigue characteristics, and thus could be used as a feasible test method to evaluate the thermal fatigue of ACWL. Highlights A set of 10-year weather data covering major cities in China was used to calculate surface temperature field change on ACWL in high-speed railway system. A 3-dimensional thermo-mechanical coupled FEM model was established and verified to investigate the daily reduced temperature effect on high-speed railway ACWL. The customized overlay tester was innovatively employed to simulate thermal load characteristics of the reduced temperature effect.
