title: Mars Target Encyclopedia - Labeled LPSC abstracts for four Mars missions

description: This data set contains annotated text versions of 1635 two-page abstracts published at the Lunar and Planetary Science Conference from 1998 to 2020 of relevance to four Mars missions. 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 <strong>Contains</strong>(Target, Element | Mineral) and <strong>HasProperty</strong>(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: "Targets from the Spirit Mars Exploration Rover in the Mars Target Encyclopedia", Kiri L. Wagstaff, Raymond Francis, Matthew Golombek, Steven Lu, Ellen Riloff, Leslie Tamppari, Yuan Zhuang, and Thomas Stein.<br> <em>53rd Lunar and Planetary Science Conference</em>, Abstract #1231, March 2022. "The Mars Target Encyclopedia Now Includes Mars Pathfinder and Mars Phoenix Targets", Kiri L. Wagstaff, Raymond Francis, Matthew Golombek, Steven Lu, Ellen Riloff, Leslie Tamppari, and Thomas C. Stein.<br> <em>52nd Lunar and Planetary Science Conference</em>, Abstract #1278, March 2021. 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. <strong>Contents</strong>: mpf.zip: 591 abstracts relating to the Mars Pathfinder mission (1998-2020) mer-a.zip: 397 abstracts relating to the MER-A (Spirit) rover mission (2004-2020) mer-b.zip: 256 abstracts relating to the MER-B (Opportunity) rover mission (2005-2020) 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. <strong>Attribution</strong>: If you use this data set in your own work, please cite it as follows: Kiri L.
