Hello Han,
thanks a lot for your quick answers!
I would have one more question regarding point 2 (for which I am also attaching a screenshot). I understand that segmentation and overlap are crucial for kappa calculation and I have actually read also the Holle&Rein paper. In the situation I am describing, segmentation differs strongly from one tier to the other (since one tier has one single, long segment “x”, whereas the other has many, alternating “x” and “y” segments), but overlap should not be reducing the kappa result, since all “x” segments contained in the second tier overlap completely with the single “x” segment of the first tier. So, I would not expect a very low kappa result. Or am I overlooking/misunderstanding something?
Thanks again and best regards,
Marta
