Dear all,

For now, I will keep the site closed for registrations; but everyone can independently invite people to join using the following link to generate an invite:

If you know someone who wants to join this instance, then please do give them an invite!

Consider the instance open for those who know anyone on

"Sense of community" and an initial seed of some 40 IR researchers should be enough to keep those spammers out of here and still grow the club!

Enjoyed giving a lecture on "Bias in Recommendations" at the SIKS Course "Advances in Information Retrieval," where I explained a bit about our challenges in working with implicit feedback (clicks), and was happy to discover Thorsten Joachims' seminal paper on implicit feedback late yesterday evening in preparation of these slides 😉!



Pinafore v1.14.0 

David @graus provides compelling scientific evidence that the filter bubble, if it exists at all, benefits diversity more than it hurts diversity.

researcher in NL or B (or keen on visiting Amsterdam):

Better register soon: may run out of capacity, so if you are not quick...

Nice question, how to learn something global in a NN approach.

Interesting detail from answer by Mostafa Deghani: include extra value into embedding to help it learn an (i?)df-like feature.

And @suzan mentions recent paper on Bert rediscovering the NLP pipeline.

On to Tilt Utrecht!

Once you get the hang of it, please consider writing an toot and pin that to your profile.

I recommend @laura 's intro to Mastodon (link below), and tech savvy ppl may even like to glance over the ActivityPub W3C standard to grasp the full power. I use Pixelfed and as other ActivityPub services.

Welcome to the Fediverse Siks PhD students!

The "unofficial" Information Retrieval Mastodon Instance.

Goal: Make a viable and valuable social space for anyone working in Information Retrieval and related scientific research.

Everyone welcome but expect some level of geekiness on the instance and federated timelines.
