IDF.social is your home if you know:

\[
\textit{idf} = - \log \frac{n_t}{N}
\]

and... everyone else!

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:

https://idf.social/invites

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 IDF.social.

"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!

In hghschool, when I read Schachnovelle by Stefan Zweig, I wished I played chess better, what a story.

Now I feel the same due to The Queen's Gambit, a highly recommended Netflix series!

Go Pepijn!

Mayor of Almere lauds Martin Kersten for his work on MonetDB, "his brainchild" and a benchmark for database systems throughout the world.

Stonebraker, Apers, Weikum collaborated with Peter Boncz and Stefan Manegold for a pretty nice surprise to Martin!

Just about 200 ppl attending Martin Kersten's CWI Lectures workshop, basically the goodbye CWI workshop (upon "virtual" retirement).

Now Anastasia Alaimaki talking about "real-time intelligence", stating that "preparation kills discovery" (i.e., getting the ETL right only works for questions that you already know how to answer).

Roel van der Burg's MSc defense: what do the search behaviours of legal searchers tell us about their information needs and interests?

We were one of 84 TREC 2020
participants - this year, in the News track only. Incredible portfolio of test collections since 1992!

TREC is not a competition, but I'm still proud on ranking 2nd in background linking, with the MSc thesis work by Pepijn Boers. Using graphs to represent documents instead of bag-of-words, a highly original approach that can be developed further.

Happy to be in the NIST green auditorium for TREC 2020 - well, the online variant, which looks suspiciously familiar to Ellen Voorhees her living room, with the beautiful TREC quilt in the back.
