I'm looking for the old Epinion dataset. The dataset includes 22166 users and 355754 social connections. It was available on http://www.public.asu.edu/~jtang20/datasetcode/truststudy.htm. But I can not find it on the internet.

More broadly, I am looking for a dataset which contains: user-item rating, user-user connection, and user-user trust matrices. unfortunately, the Epinion dataset on the trustlet.org website does not contain user-user connection. It is appreciated if you could help me finding the dataset.

The old Epinion dataset is available from this archived version of the page you have linked to:

Update

Currently, Jiliang Tang works at Michigan State University (and not at Arizona State University).
New versions of the Epinion dataset are available here.

  • @soroush, the whlole /jtang20 catalog is unavailable, probably because J. Tang had left ASU in February 2015: cse.msu.edu/~tangjili/jiliang_tang.pdf
