Example of the prerequisite for our task setting, demarked continuous spans as seen in (a) and the output, semantic categories assigned to the input spans as seen in (b). “2-comp-sys”, “Pro” and “+Regulation” are used as short-hands for “Two-component system”, “Protein” and “Positive regulation” respectively. Note the potential for partial overlap of different semantic categories as can be seen for the “Protein” and “Two-component system” annotations.
