Visualising Collaboration in Astronomy

Over on this link, you’ll find a data-driven document (D3 FTW!) showing collaboration between the most authorship-intensive institutions in astronomy. The document is a chord diagram showing the strength of collaboration between research centres, based on co-authorship of papers. I’ve included some screenshots here to give you the idea - the one above is for worldwide institutions... Continue Reading →

Mapping Collaboration in Astronomy

A couple of weeks ago I began to geocode the database of astronomical research I scraped from NASA ADS during .Astronomy 4. This database consists of all the published astronomical research in five major journals (almost 250,000 papers going back decades, from MNRAS, ApJ, AJ, A&A and PASP) up to July 2012. You can read...

Geocoding the Literature

I (or rather my computer) spent most of this morning geocoding the database of astronomical papers that I scraped from NASA ADS a while back. I’ve got about a quarter of a million papers, covering several of the major astronomical journals (MNRAS, ApJ, A&A, PASP and AJ) back to their first publications. There are 7... Continue Reading →

Authorship in Astronomy

If you’ve been following the recent series of posts about my data mining, then a) I apoligise and b) it just got better! The short story is that research in astrophysics is generally made available online and is entirely available, in digital form, all the way back to the begining of the refereed jounrals on...

Astrochemistry Word Matrix

Just for fun, I took a list of molecules you can find in space and made a word matrix from it. The result shows the relationship between molecular species and their occurrence in the astronomical literature. There is a nice cluster of Hydrogen-bearing molecules that seem to correlate well, same for Carbon. I don’t even know... Continue Reading →

Mining the Astronomical Literature

At .Astronomy 4 in Heidelberg, I began hacking on some natural language processing of the astronomical literature as part of my Hack Day project with Sarah Kendrew and Karen Masters. It began as a version of BrainScanr for astronomy - which it can still become - however it also provides an interesting database to explore,... Continue Reading →
