KOI at SemEval-2018 Task 5: Building Knowledge Graph of Incidents
Paramita Mirza, Fariz Darari, Rahmad Mahendra · 2018
We present KOI (Knowledge of Incidents), a system that given news articles as input, builds a knowledge graph (KOI-KG) of incidental events.KOI-KG can then be used to efficiently answer questions such as "How many killing incidents happened in 2017 that involve Sean?"The required steps in building the KG include: (i) document preprocessing involving word sense disambiguation, named-entity recognition, temporal expression recognition and normalization, and semantic role labeling;(ii) incidental event extraction and coreference resolution via document clustering; and (iii) KG construction and population.* Both share the same amount of work. 1
