Quantification of the Disciplinary Roots of Astrobiology
The questions of astrobiology span many scientific fields. This project analyzes databases of scientific literature to determine and quantify the diverse disciplinary roots of astrobiology. This is one component of a wider study to build a map of relationships between the constituent fields of astrobiology, so relevant knowledge in diverse fields can be most efficiently inform the study of life in the universe.
We have identified the most relevant databases of scholarly literature in astrobiology and related fields, crafted initial search strategies designed to isolate a core corpus of astrobiology publications across multiple databases, and have begun work on a term co-occurrence analysis to relate the literature of astrobiology to relevant work from diverse fields.
