Constant Field Values

predModelLocation

protected String predModelLocation

PARAM_ROLE_MODEL_LOCATION

public static final String PARAM_ROLE_MODEL_LOCATION

Location from which the roleset classification model is read.

PARAM_SRL_MODEL_LOCATION

public static final String PARAM_SRL_MODEL_LOCATION

Constant Field Values

srlModelLocation

protected String srlModelLocation

PARAM_EXPAND_ARGUMENTS

public static final String PARAM_EXPAND_ARGUMENTS

Normally the arguments point only to the head words of arguments in the dependency tree. With this option enabled, they are expanded to the text covered by the minimal and maximal token offsets of all descendants (or self) of the head word.

Warning: this parameter should be used with caution! For one, if the descentants of a head word cover a non-continuous region of the text, this information is lost. The arguments will appear to be spanning a continuous region. For another, the arguments may overlap with each other. E.g. if a sentence contains a relative clause with a verb, the subject of the main clause may be recognized as a dependent of the verb and may cause the whole main clause to be recorded in the argument.
