We introduce a new chemical information extraction shared task, named ChEMU, part of the 11th Conference and Labs of the Evaluation Forum (CLEF-2020). ChEMU proposes two key information extraction tasks over chemical reactions from patents. Task 1 --- named entity recognition (NER) --- is to identify specific types of chemical compounds, i.e. to assign the label of a chemical compound according to the role for which the chemical compound plays within a chemical reaction. Task 2 --- event extraction over chemical reactions (EE) --- involves on the other hand event trigger detection and argument recognition. We will publicly release reaction-specific gold standards --- that we describe in this pressentation --- derived from patent literature and annotated by chemists (for NER and EE, resp.) in early 2020. Thereafter academic or industrial teams working in the field will be encouraged to participate in a shared evaluation campaign, by developing and contributing NER and EE models. The models will be then evaluated (by measuring their recall, precision and F1 scores), compared and jointly discussed at CLEF-2020.
