Hi, thanks for your interest! For each 'sentence' in the sentences.pkl file, the field 'is_negative' denotes whether this expression is an absence expression (e.g., "dog without leash") or not. More specifically, a 'sentence' with 'is_negative' as True means it is an absence expression and False means it is a presence expression.

We also explain this in the documentation of d-cube, but we called absence expression as "anti-expression" at that time. We call it absence expression now.

If you have further questions, please feel free to mention them.
