Research by @djoerd his MSc students. A project presented by Jan Trienes, on "who to follow" on Mastodon.

Results of scientometric analysis of 21.2M WoS papers published 2000-2017

Identified the classic, the CHIIR, and the bio-informatics perspectives on IR. (Probably some bias toward journal papers due to WoS.)

Uses VOSviewer and the Leiden Algorithm (Traag et al., 2018)

Ludo discusses the similarity between Pagerank vs. the classic Pinski and Narin scientometrics paper in IP&M (1976).

For history of Pagerank before Pagerank, see also arxiv.org/abs/1002.2858

Second keynote by CWTSs Ludo Waltman on the intersection between Scientometrics and IR

Users often decision takers interested in an overview of domain instead of specific articles.

Co-citation analysis White and McCain 1998 illustrates historically strong connection even if separate subdomains

The "unofficial" Information Retrieval Mastodon Instance.

Goal: Make idf.social 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.
