the source of the dataset

[changym3]

Hi, thanks for your works. I wonder the source of the .mat form of ACM dataset because I'm a little confused about some parts of its meaning, i.e. what does the 'n' in ACM['nT'] and ACM['nnPvsT'] mean? And I also want to know do you preprocess the DBLP and IMDB from scratch (i.e. from the official release), or borrow that from other papers? If the latter, I want to know that source.

Regards.
