Peter Klügl commented on UIMA-3661:
-----------------------------------
Yes, that is a stupid problem. Just to clarify it for others: The annotation
with the covered text "XY (KQ)" is not matched, because parenthesis are not
visible. One would think that only SegmentElements starting with a parenthesis
are not matchable. This is quite counterintuitive, but the begin AND the end
need to be handled the same way because of the variable matching direction
supported by Ruta.
I agree that we need a better and cleaner concept for visibility. I always
thought that our concept is much more powerful than related implementations
such as JAPE. They are type-based, we are coverage-based, but that comes with a
price.
I invite everyone to discuss what should be visible/matchable.
> Ruta: specification for "Filter & Retain"

> Key: UIMA-3661
> URL: https://issues.apache.org/jira/browse/UIMA-3661
> Project: UIMA
> Issue Type: Wish
> Components: ruta
> Affects Versions: 2.1.0ruta
> Reporter: Martin Toepfer
>
> It would be nice if we had a specification for inference with filtered and
> retained types, as well as some options for handling filtered/retained types
> (covered text vs. annotations).
> For instance, I am trying to merge SegmentElement annotations into Segment
> annotations (Segment is roughly SegmentElement+). I am not interested in
> parenthesis or colons, so I add them to the filtered types. However, I have
> SegmentElements that contain parenthesis, thus, I add SegmentElements to
> retained types. Nevertheless, not all SegmentElements are used, because some
> SegmentElements end with closing parenthesis, e.g., "XY (KQ)", which is a
> valid element in my case.
> At the moment, I cannot use filter/retain for this problem. Changes may
> affect many parts of the inference, however, I think that it would be a very
> nice feature for UIMA Ruta 3.0.
