Begin and End of spans

[SarehAghaei]

When the beginning and end of spans are not the same, I encounter an error when calculating Krippendorff.
For instance, this error arises when working with the following matrix/dataframe.

begin end annotation
84 95 c1
96 100 c3
84 95 c1
96 99 c3

The error arises due to a RuntimeWarning indicating an invalid value encountered during scalar division. Specifically, it occurs at the calculation step: 1 - (o * d).sum() / (e * d).sum()

Krippendorff assumes that the spans are the same and only the labels/annotations differ. In your case, you could either 1) manually ignore non matching annotations (if that makes sense in your use case) or 2) use the gamma IAA measure (also provided in inceptalytics
