Summary: Ruta: Relevance/Purpose of GATHER
Key: UIMA-6407
URL: https://issues.apache.org/jira/browse/UIMA-6407
Project: UIMA
Issue Type: Question
Components: Ruta
Affects Versions: 3.1.0ruta, 2.8.1ruta
Reporter: Michael Stenger
Hi.
This is just a question for clarification on the functionality of action
GATHER. As far as I can tell, it creates a new annotation of the given type,
spanning the matched annotation of the given rule elements and allows to assign
them to the features of the created annotation.
But how is this different from the CREATE action? I'd argue that the latter can
do the same and more, which would render GATHER irrelevant. Just by using
LabelExpressions instead of NumberExpressions as arguments:
{noformat}
A B{-> GATHER(C, 1, 2, "a" = 1, "b" = 2)};
// VS
x:A y:B{-> CREATE(C, 1, 2, "a" = x, "b" = y)};{noformat}
Some clarification would be great. Thank you.
Best, Michael
