> Type-based filtering in Ruta rules
> ----------------------------------
>
> Key: UIMA-6137
> URL: https://issues.apache.org/jira/browse/UIMA-6137
> Project: UIMA
> Issue Type: New Feature
> Components: Ruta
> Reporter: Mario Juric
> Assignee: Peter Klügl
> Priority: Major
>
> The visibility concept in Ruta is not type-based but type coverage-based,
> which means that filtered types will hide the are they cover to the Ruta
> rules, i.e. these areas become invisible to the rules.
> We have a use case where we only want to hide the types from being considered
> in the rules, and not the covered text area where other types found in these
> areas should still be considered by the rules.
> We use Ruta as part of the normalization process where we have different text
> areas marked with annotations associated with the tags in the original
> content (title, abstract/summary, body, COI, authors, citations etc.), and
> Ruta is part of the parsing process that produces this view. Using only the
> content annotations Ruta is then used to markup what areas to include in a
> new view for doing NLP. This approach gives us maximum traceability of the
> normalization process.
> However, the different types of content annotations can sometimes interfere
> with the rules beyond our control, and our current solution leads to more
> awkward rules that are hard to verify, and which also leads to a less
> performant implementation. The problem would in our case better be solved if
> we were able to tell Ruta simply to ignore certain types from being
> considered, i.e. they are invisible to the Ruta rules. Preferably we want to
> be able to add and remove filtered types in the script similar to how it
> works with the coverage based type filter.
> Please see also this mailing list thread where a toy example of the problem
> is discussed:
