Example of Event Extraction.

Biomolecular interactions and regulations are automatically extracted from text as directed graphs with genes and proteins as leaves (circles) and event types as the intermediate nodes (rectangular boxes). The “Theme” denotes the subject of the association (e.g., what is being regulated), while the “Cause” denotes the object (e.g., the regulator). In a subsequent step, pairwise relations are extracted, directly linking two genes in a format compatible with systems biology studies.
