The UC3M system was originally developed for the temporal expressions recognition and normalization (TERN task) in Spanish texts, according to the TIDES standard. Current version supposes an almost-total refactoring of the earliest system. Additionally, it has been adapted to the TimeML annotation schema and a considerable effort has been done with the aim of increasing its coverage. It takes a rule-based design both in the identification and the resolution phases. It adopts an inductive approach based on the empirical study of frequency of temporal expressions in Spanish corpora. Detecting the extent of the temporal expressions the system achieved a Precision/Recall of 0.90/0.87 whereas, in determining the TYPE and VALUE of those expressions, system results were 0.91 and 0.83, respectively.5application/pdfeng© AuthorsAtribución-NoComercial-SinDerivadas 3.0 Españaconference paperInformáticaopen access329332Proceedings of the 5th International Workshop on Semantic EvaluationCC/0000022920
