Astrobiology Keywords
As part of the Astrobiology Resource Metadata Standard (ARMS), we have developed a set of astrobiology keywords to characterize the content of Astrobiology Resource, such as datasets and research papers.
The ARMS set of keywords is a compilation of publication-style keywords extracted from Astrobiology related journals over the past 10 years 1. After careful curation of the keywords, we developed a 4 tier taxonomy with over 750 taggable keywords.
To help users find and select keywords, they are organized hierarchically, under a top-level structure of 11 categories:
- Astronomical
- Biological
- Chemical
- Computational
- Environmental
- Exploration
- Geological
- Institutional
- Methods
- Planetary
- Process
We validated the keywords against the abstracts of AbSciCon 2019, and LPSC 2019, using the keywords as automatic indices. We also performed a cluster analysis and enhanced the ARMS lexicon with a few additional keywords present in the AbSciCon 2019 abstracts.
