Mars Target Encyclopedia - Labeled LPSC abstracts for four Mars
missions
(phx.zip: Mars Phoenix Lander mission)

This data set contains annotated text versions of mission-relevant
two-page abstracts published at the Lunar and Planetary Science
Conference.  The annotations were generated using named entity
recognition and relation extraction provided by the MTE processing
pipeline (available at https://github.com/wkiri/MTE), followed by
manual review.  Annotated entities include Element, Mineral,
Property, and Target.  Annotated relations include Contains(Target,
Element | Mineral) and HasProperty(Target, Property). The
extracted information (without full texts) is also available as a
database (stored in .csv files)
at https://pds-geosciences.wustl.edu/missions/mte/mte.htm .  The
complete annotated texts are provided here as a resource for further
research and experimentation on information extraction methods.  For
more information about the Mars Target Encyclopedia and these
annotations, please see:

The original PDF abstracts are available at:

* For years prior to 2000:
  https://www.lpi.usra.edu/meetings/LPSC${two-digit-year}/pdf/${id}.pdf 
* For year 2000:
  https://www.lpi.usra.edu/meetings/LPSC${four-digit-year}/pdf/${id}.pdf
* For years 2001-2017 (note lower-case lpsc):
  https://www.lpi.usra.edu/meetings/lpsc${four-digit-year}/pdf/${id}.pdf
* For years 2018-2020:
  https://www.hou.usra.edu/meetings/lpsc${four-digit-year}/pdf/${id}.pdf
where ${id} is a four-digit abstract number, starting with 1001 (if available).

The text files provided in this archive were extracted from the PDF
files using the Apache Tika PDF parsing tool.  They are named as
${four-digit-year}_${id}.txt.  The text is provided here so that the
annotations can be viewed in context.  The text content remains
copyright of the original abstract authors. 

The annotations (entities and relations) are provided in the format
used by the brat annotation tool.  They are named as
${four-digit-year}_${id}.ann. To view the annotations in a web-based
graphical form, install the brat tool (http://brat.nlplab.org/).
These annotations were generated using brat v1.3.  The annotation
files are also human-readable and can be parsed in to be used directly
in code.  If the .ann file is empty, then there are no relevant
annotations for the associated text file. 

Contents of phx.zip:
* 391 abstracts relating to the Mars Phoenix Lander mission
(2009-2020)

Each directory contains a .txt and .ann file for each abstract.  The
.ann file is in brat standoff format
(http://brat.nlplab.org/standoff.html).  Additional .conf files are
provided to generate color highlighting and keyboard shortcuts.  These
are used by the brat tool. 

Note: the same abstract may appear in more than one mission directory,
if it discusses targets from more than one mission.  It will have a
different .ann file for each such appearance.  Within each directory,
a "Target" annotation is understood to refer to a target of the
relevant mission.
