Next week, I'll be in Padua, Italy for #SIGIR25 & #ICTIR25. 🇮🇹🍝🍕🍷🍹☀️
SIGIR is one of my favourite conferences, so I'm very happy to have six co-authored works there, two of which I'll present myself. 😄
I'm looking forward to seeing many of you there! 🙂
Come check out our presentations! 🧵👇😄 0/6

I'm looking forward to reading this, Bhaskar!
Those damn aliens are always so hard to reach! 👽
My colleagues published about pairwise relevance labeling this last year (and even earlier on arXiv):
aclanthology.org/2024.finding...
Why I personally think it works better, mainly because it's hard to calibrate a pointwise relevance prediction, but a pairwise prediction hardly needs calibration.
