Edit transducers for spelling variation in Old Spanish
Jordi Porta, José Luis Sancho, Javier B. Gómez · 2013
A system for the analysis of Old Spanish word forms using weighted finite-state transducers is presented. The system uses previously existing resources such as a modern lexicon, a phonological transcriber and a set of rules implementing the evolution of Spanish from the Middle Ages. The results obtained in all datasets show significant improvements, both in accuracy and in the trade-off between precision and recall, with respect to the baseline and the Levenshtein edit distance. A qualitative error analysis suggests several potential ways to improve the performance of the system.
