Mars Target Encyclopedia: Information Extraction for Planetary Science

We created a new reference database
called the Mars Target Encyclopedia (MTE) that contains
compositional information about science targets
(usually rocks or soils) on Mars. Users can search for
all targets that contain an element (e.g., “calcium”) or
mineral (e.g., “hematite”) and see a map view of their
spatial locations (see Fig. 1). Clicking on a search result
or searching for a specific target of interest (e.g., “Dillinger”)
brings up a page that compiles previous findings
about its composition (see Fig. 2).
The information that populates the MTE was mined
from the planetary science literature using information
extraction technology. All information in the MTE is
linked to the source publication from which it was extracted,
so users can easily browse the full context in the
original document (Fig. 2).
