One other thought (probably not well-formed...): You could use 1 CAS, but multiple views.
Each view can have its own subject-of-analysis. This might not work for you, though, as you might want the original subject-of-analysis in order to preserve the "offset" values for annotations' begin and end features. Each view can have its own set of indexes. This would enable you to index just the annotations that were "in scope". But this might not work for you if the Feature Structures themselves had references beyond the "scope" - they would be valid and you might want them to be invalid or null or ?? With multiple views, it is possible to have cross-view references as values in the CAS, in case that was of interest. Perhaps this might be something to consider. -Marshall On 6/16/2014 12:23 PM, Richard Eckart de Castilho wrote: > The CasMultiplier is not a scoping operator per se. > > I understood that you want to scope your AEs to specific sections of a CAS. > Since there is no generic scoping operator in UIMA (that I would be aware of), > the next best thing one can do (I think) is to slice the CAS into multiple CAS > that each represent the scope you want to work on and merge them in the end. > > Cheers, > > -- Richard > > On 16.06.2014, at 11:47, Dr. Armin Wegner <arminweg...@googlemail.com> wrote: > >> Hello Richard! >> >> As far as I know, CasMultipliers split the CAS in two or more new >> CASes, that are processed independently, and must be put together to a >> final CAS again.
