We noticed many labs at #clef2019 tasked with "rating people and free speech", not least our own PAN. Much of what we do was put into perspective by Yair Neuman @bengurionu in his keynote: http://ir.inf.usi.ch/clef/NEUMAN-CLEF-2019-FINAL.pdf

In the past few days, we've been attending #clef2019 to chair our PAN lab on digital text #forensics and #stylometry, and to announce our new Touché lab on argument retrieval at #clef2020. Now on the train back from Lugano, here are a few pickings. https://t.co/VdFYO1rYGd
