ReproduceAbstract
The paper reports on exploring various machine learning techniques and a range of textual and meta-data features to train classifiers for linking related event templates automatically extracted from online news. With the best model using textual features only we achieved 94.7\% (92.9\%) F1 score on GOLD (SILVER) dataset. These figures were further improved to 98.6\% (GOLD) and 97\% (SILVER) F1 score by adding meta-data features, mainly thanks to the strong discriminatory power of automatically extracted geographical information related to events.
