Hello,

what is the best practice to process CASes resulting from multiple and different AAEs? Assume I have an AAE1 processing document collection 1 and an AAE2 processing document collection 2. Now I would like to compare each tuple of the resulting CASes of AAE1 and AAE2 using a third AAE. My underlying intention is to "compare" each document in collection 1 with each document in collection 2 using different preprocessing pipelines.

Is there some abstraction in UIMA to perform this? I saw an solution performing an n-cross-m comparison using two views where each view represented a different document. This works but seems a bit inflexible, assuming you need to configure different processing pipelines for each collection type.

Regards,
Mateusz
