Abstract

In this work we present a rule-based system for recognizing and normalizing temporal expressions in Indonesian documents. We adapt an existing temporal expression normalizer for English, TimeNorm, for Indonesian language. We then build a finite state transducer based on the crafted TimeNorm grammar for Indonesian, to recognize temporal expressions in texts. The system yields good results of 92.87 % F1-score and 85.26 % F1-score for recognizing and normalizing temporal expressions respectively.
