Abstract

We present here a practical method for adapting a NER system for Spanish to Portuguese. The method is based on training a machine learning algorithm, namely a C4.5, using internal and external features. The external features are provided by a NER system for Spanish, while the internal features are automatically extracted from the documents. The experimental results show that the method performs well in both languages Spanish and Portuguese.
