"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!

The proceedings of 9th PhD Symposium on Future Directions in Information Access (FDIA 2019) held in conjunction with ESSIR 2019 in Milan are online now - please see to see what talented young researchers are working on!

Useful contribution by SIGCHI on the road to open access:

"All of the organisations that I’ll be discussing (ACM, arXiv, IEEE, and USENIX) generate an annual revenue that covers operating costs and a surplus that is reinvested in the community and/or held as assets. These assets are crucial to secure on-going financial commitments and underwrite events. Building up these assets is necessary to underwrite increased financial liabilities as these organisations grow."

And neither is Apple."

@djoerd and myself pitched NoGA, a newly funded project to help organizations take Web analytics in their own hands.

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.
