Dear colleagues,

You might be interested to learn that Clarivate Analytics has agreed to make available a Web of Science data set (111,616 articles in Astrophysics and Astronomy, "Astro Data Set") which allows us to invite everybody interested to participate in a topic extraction challenge so we can collectively study and learn from the systematic comparison of topic extraction approaches. For details about the challenge and how to access the data see: www.topic-challenge.info<http://www.topic-challenge.info>.

The activity of exploring differences between topic extraction approaches originated from discussions at the annual advisory board meeting of a project on measuring the epistemic diversity of research by Frank Havemann, Michael Heinz and Jochen Gläser in Berlin, Germany, and is documented in a special issue "Same Data, Different Results?" of the journal Scientometrics (see list of forthcoming articles below).

We would like to invite you and your colleagues to participate in the topic extraction challenge, and would appreciate your support in  spreading the news. A first opportunity to discuss new topic extraction solutions and the challenge of comparing approaches will be provided this October at a special session at the 2017 ISSI conference in Wuhan, China (http://www.issi2017.org). Submission deadline for research in progress papers is April 10. You are welcome to forward this invitation to others who may have an interest in topic extraction from the Astro Data Set. Please send questions to theresa.velden at gmail.com<mailto:theresa.velden at gmail.com>.

With kind regards,

Theresa Velden
(& the other "challengers": Kevin Boyack, Wolfgang Glänzel, Jochen Gläser, Frank Havemann, Andrea Scharnhorst, Bart Thijs, Nees Jan van Eck, Ludo Waltman)
