Abstract

This paper presents the conclusions reached from the development of a system for Named Entity recognition in written Basque. In order to obtain this recognizer we have worked with different types of classifiers, one of them based on linguistic information and others constructed using machine learning methods. Taking these classifiers as starting point, and once we explain the different attempts done with each simple method using different information sources, we present the experiments we did combining those single methods in order to improve the performance and obtain a more robust system. Finally, we explain some conclusions and lessons we have learned from all these experiments, especially useful when dealing with named entity recognition in languages others than English.
