verb

A list of the word indices of the words that compose the verb whose arguments are identified by this instance. This will contain multiple word indices when multi-word verbs are used (e.g. 'turn on').

verb_head

The word index of the head word of the verb whose arguments are identified by this instance. E.g., for a sentence that uses the verb 'turn on,' verb_head will be the word index of the word 'turn'.

arguments

A list of (argspan, argid) tuples, specifying the location and type for each of the arguments identified by this instance. argspan is a tuple start, end, indicating that the argument consists of the words[start:end].
