To be free of course!

I am confused: At the #SIGIR business meeting, the executive committee claimed that "all ACM SIGIR publications are permanent open access on the DL", but that is clearly not the case, see my attempt to download Bruce Croft's SIGIR 2019 keynote paper.

Clair Patterson is one of the most underrated scientists ever: He estimated the earths age based on uranium-lead dating, and successfully defied big oil to save us all from lead poissoning, even though the oil lobby deprived him from a lot of funding.

Going to find out how deep learning works for Information Retrieval with Dacheng Tao. #SIGIR2020

Norbert Fuhr's recommendations for gaining scientific knowledge from experiments:

1. Do not use MRR or MAP;
2. Instead of relative improvements, regard the effect size!
3. For multiple significance tests, use a correction, such as Bonferoni or Tukey's HSD (NB comparing only to the 2nd best method does not help!)
4. There are no significant improvements for re-usable test collections! (hypotheses have to be formulated before the work)

Nice! Harrie Oosterhuis presenting a new counter-factual learning to rank approach that takes the item display policy (top-k cut-off) into account. #SIGIR2020

Eye opener. Johanne Trippas brought a game of cards with faces of Turing award winners: They're all male! 😮

Today at 18:30h. CEST discuss REL, the Radboud Entity Linker, with Faegheh @fhasibi Hasibi. #SIGIR2020

Guoxiu He discusses the creation of a children-friendly reading environment (focusing among others on detecting pornographic material) #SIGIR2020

Lei Han studied how people search while using Jupyter notebooks. #SIGIR2020

Gregory Goren studies how to counter-act adverserial attacks (read: SEO) on search algorithms.
This work is desparately needed in IR! #SIGIR2020

Zong-Ben Xu's #SIGIR2020 keynote discusses machine learning along 4 hypotheses.
