Biological processes are complex phenom- ena involving a series of events that are re- lated to one another through various relation- ships. Systems that can understand and rea- son over biological processes would dramat- ically improve the performance of semantic applications involving inference such as ques- tion answering (QA) ? specifically ?How?? and ?Why?? questions. In this paper, we present the task of process extraction, in which events within a process and the rela- tions between the events are automatically ex- tracted from text. We represent processes by graphs whose edges describe a set of temporal, causal and co-reference event-event relations, and characterize the structural properties of these graphs (e.g., the graphs are connected). Then, we present a method for extracting...
