Italian Event Detection Goes Deep Learning.

This paper reports on a set of experiments with different word embed- dings to initialize a state-of-the-art Bi- LSTM-CRF network for event detection and classification in Italian, following the EVENTI evaluation exercise. The net- work obtains a new state-of-the-art result by improving the F1 score for detection of 1.3 points, and of 6.5 points for classifica- tion, by using a single step approach. The results also provide further evidence that embeddings have a major impact on the performance of such architectures.
