Exploiting Multilingual Grammars and Machine Learning Techniques to Build an Event Extraction System for Portuguese
We describe a methodology for building event extraction systems. The approach is based on multilingual domain-specic grammars and exploits weakly supervised machine learning algorithms for lexical acquisition. We report on the process of adapting an already existing
event extraction system for the domain of conflicts and crises to the Portuguese language.
