Abstract
We present a novel natural language processing (NLP) approach to deriving plain English descriptors for science cases otherwise restricted by obfuscating technical terminology. We address the limitations of common radio galaxy morphology classifications by applying this approach. We experimentally derive a set of semantic tags for the Radio Galaxy Zoo EMU (Evolutionary Map of the Universe) project and the wider astronomical community. We collect 8486 plain English annotations of radio galaxy morphology, from which we derive a taxonomy of tags. The tags are plain English. The result is an extensible framework, which is more flexible, more easily communicated, and more sensitive to rare feature combinations, which are indescribable using the current framework of radio astronomy classifications.

Search for 511 keV Emission in Satellite Galaxies of the Milky Way with INTEGRAL/SPI
Siegert, T.; Diehl, R.; Vincent, A.~C.; Guglielmetti, F.; Krause, M.~G.~H.; Boehm, C. (2016-10-24)The positron annihilation gamma-ray signal in the Milky Way (MW) shows a puzzling morphology: a very bright bulge and a very low surface-brightness disk. A coherent explanation of the positron origin, propagation through ... -
The Radio Continuum-Star Formation Rate Relation in WSRT SINGS Galaxies
Heesen, V.; Brinks, E.; Leroy, A.K.; Heald, G.; Braun, R.; Bigiel, F.; Beck, R. (2014-04-02)We present a study of the spatially resolved radio continuum–star formation rate (RC–SFR) relation using stateof-the-art star formation tracers in a sample of 17 THINGS galaxies. We use SFR surface density (ΣSFR) maps ...
