Mapping

If a file is passed to the predictor, the predicted spans will be converted into a new ontology. The file format should be

<original parent label>\t<original label>\t<new label>

If the predicted span is labeled as <original label>, and its parent is labeled as <orignal parent label>, it will be re-labeled as <new label>. If no rules match, the span and all of its descendents will be ignored.

The <original parent label> is optional. If the parent label is @@VIRTUAL_ROOT@@, then this rule matches the first layer of spans. In semantic parsing, it matches events. If the parent label is *, it means it can match anything.
