toString

public String toString()

Operation: 1. Check in_chunk: trg and pro in the same chunk, pro preceeds trg, trig's POS is a NN if trg's POS is VBx and trg is a reg event -> PRO is used as cause 2. Find connection: NP prep NP : if trig is NP and not (in_chunk) use known list of preps to connect with another NP 3. Check role: if there is more than one trig in chunk, check relationship (equals, dependent) between trgs two trig are equal if they connected by CC (i.e. and,or) and has the same POS 4. Divide into simple/binding/reg event to make extraction process simpler 5. How to store extracted events? How to assign ID?-> List of extracted event, reference via object ID
