Data annotation

[Buted]

Thanks for your generous work!
I'd like to do some experiments based on the dataset that you provided. But I wonder how the annotations (not raw texts) are generated.
Can you give me some information?

This is an annotation example copied from your annotation files:

T4 Positive_regulation 573 581 elevated

How is the 'elevated' word labeled as a 'Positive_regulation' trigger?
