Comparison of hybrid journal indexing by data source, 2019–2023. Only hybrid journals present in the cOAlition S Transformative Agreement Data dump with at least one open access article are considered. A presents the number of journals, B the number of articles (DOI), distinguishing between shared DOI corpus and surplus in hoaddata. Box plots C shows the 5-years journal article volume (log scale). Note that intersections sets with at least 30 journals are shown

Development of open access in hybrid journals in transformative agreements by data source and author role, 2019–2023. Figure shows the open access percentage (A), the number (B) and the percentage (C) of open access articles enabled by transformative agreements.

Just out: Open metadata enable large-scale hybrid open access studies. Cross-database comparison using major bibliometric databases shows that transformative agreements have been the main driver of open access. But paywalls still dominate.

Two websites, one journal. The Journal of Informetrics has been hijacked. This is not just any journal, it's a well-known title published by Elsevier.
More journals from reputable publishers are being hijacked since recently.
Guess which screenshot belongs to the original journal?

GitHub - jhculb/WideSky: Tool for Bulk Injestion of the BSky Firehose into Postgres Tool for Bulk Injestion of the BSky Firehose into Postgres - jhculb/WideSky

Anyone interested in studying BlueSky data in bulk?

I've just released an app that consumes the firehose and stores it in PostgreSQL for easy use. Hope it's useful!

AI research summaries ‘exaggerate findings’, study warns Bots’ tendency to display ‘unwarranted confidence’ and fixate on ‘pink elephants’ particularly risky in medical research, according to new paper

AI tools overhype research findings far more often than humans, with a study suggesting the newest bots are the worst offenders – particularly when they are specifically instructed not to exaggerate

The raison d'être of academic publishing is to publish output that meets a basic requirement of quality: that people should be able to trust that it isn't fundamentally wrong.

This feature shows a shocking disregard for that with a lazy caveat about it being AI content & 'the quality may vary'.

Had not given this too much thought before, but yes, retracted studies can have a sizeable effect on meta-analyses conclusions

Three AI-powered steps to faster, smarter peer review Tired of spending countless hours on peer reviews? An AI-assisted workflow could help.

Nothing to see here, just Nature advocating LLM peer review.

“Feed your dictated notes into an offline large language model (LLM) to clarify and organize your feedback. A simple prompt such as “Write a critical reviewer letter based on the following notes. Maintain a professional tone throughout”

DS9 was so funny and great with this, Weyoun was a one off character who died at the end of his episode and everyone was like damn Weyoun was so cool we love Jeffrey Combs and then everyone realized it was Star Trek and you could do whatever you want so we got nine Weyouns running around

Hello Bluesky, I guess I should introduce myself.
I'm Jack, I enjoy bibliometrics and Open Science research.
When I have time I'm also pursuing my PhD.
I created the Open Research Converter (the ORC) orc-demo.gesis.org, and looked at the reference coverage of OpenAlex arxiv.org/abs/2401.16359.
