Our system explored a multi-stage approach including trigger detection, edge detection and event composition. After trigger edge detection is finished we are left with a semantic graph from which we must select the optimal subset that is consistent with the semantic frames for each event type. The system achieved an F-score on the development data of 73.67 but was ranked 5th out of six with an F-score of 29.94 on the test data. How-ever, precision was the second highest ranked on the task at 62.73. Analysis suggests the need to continue to improve our system for complex events particularly taking into account cross-domain differences in argument distributions. date: 2016-03-26 date_type: published full_text_status: public pres_type: poster event_title: SW4PHD: the 2016 Scientific Workshop for PhD Students event_location: Hanoi event_dates: 26 March 2016 event_type: workshop refereed: TRUE citation: Tran, Mai Vu and Le, Hoang Quynh and Phi, Van Thuy and Pham, Thanh Binh and Nigel, Collier (2016) Exploring a Probabilistic Earley Parser for Event Composition in Biomedical Texts.
