Additional Information:

<div>With this work we participate in the TAC-KBP 2016 Event Nugget Track for Event Nugget Detection. We implement a simple but effective system which uses a Bi-Directional LSTM with embeddings short-cuts to the output for Event Trigger detection and simple Logistic Regression Classifiers with event trigger context features based on word embeddings for Event Type and Realis detection. Our post-submission models yield state-of-the-art results on the official task dataset.&nbsp;</div> <div>We train and evaluate our system for English and it can easily be adapted for Chinese, Spanish or other languages as our best model uses only word embeddings as external resources.</div>
