Semantic querying over the biomedical litera- ture has gained popularity, where a semantic representation of biomedical documents is re- quired. Previous BioNLP Shared Tasks exer- cised semantic event extraction with a small number of pre-defined event concepts. The GRO task of the BioNLP?13-ST imposes the challenge of dealing with over 100 GRO con- cepts. Its annotated corpus consists of 300 MEDLINE abstracts, and an analysis of inter- annotator agreement on the annotations by two experts shows Kappa values between 43% and 56%. The results from the only participant are promising with F-scores 22% (events) and 63% (relations), and also lead us to open is- sues such as the need to consider the ontology structure.
