Systematic Review Information Extraction (SRIE) 2018

Evaluation: February-November, 2018
Workshop: November 13-14, 2018


Background

The National Toxicology Program (NTP), an interagency program headquartered at the National Institute of Environmental Health Sciences (NIEHS, part of the National Institutes of Health), and the Environmental Protection Agency (EPA) conduct systematic reviews of environmental agents to identify potential human health hazards. These reviews collect toxicity or health effects information on different chemicals from the published scientific literature including study details such as experimental protocols, animal models, and results. Because this information can vary widely from study to study, the systematic review serves a critical purpose by providing a transparent, standardized, multistep approach to identify, select, assess, and synthesize information for developing objective, evidence-based conclusions about potential chemical hazards. Furthermore, because research studies done at different points in time may reflect different standards in experimental protocols or reporting procedures, the systematic review approach serves to promote transparency and facilitate reproducibility of literature-based evaluations on environmental agents.

Some elements of information extraction in these systematic reviews are straightforward, such as identifying the species or sex of the experimental models. Others are more complex as publications may report multiple experiments with various exposures and doses and evaluate multiple endpoints. Authors may report experimental details using different units, different chemical names, and other variations in terminology. In addition, this information may be located in the text of the publication, or in a table, figure caption, or the figure itself. Currently, the information extracted in a systematic review is collected through a labor-intensive, manual process that is slow and often costly. NTP and EPA are interested in adopting automated processes for information extraction in systematic reviews of environmental chemicals. The application of this task is to develop automated tools that could improve the efficiency of systematic review information extraction to reduce completion time and labor-costs while maintaining quality and reproducibility. The results of this task will inform future NTP and EPA efforts aimed at systematic review automation, including subsequent challenges.

Objective

The purpose of the Systematic Review Information Extraction (SRIE) track is to develop and evaluate Information Extraction (IE) approaches that can assist in the systematic reviews of environmental agents. This track focuses on IE of experimental design factors found in the Material and Methods section ("methods section") of published studies of experimental animals exposed to environmental chemicals. The first goal of the track is to identify and annotate the experimental design factors. The second goal of the track is to identify relations between different experimental design factors and assign the factors into logical groups.

Overview

The SRIE track has two tasks:

  • Task 1: Experimental design factors for the categories of exposure, animal group, dose group, and endpoint should be identified and the appropriate annotation tag applied.
  • Task 2: Relations between experimental design factors from Task 1 should be identified, the factors assigned to groups, and the appropriate annotation tag applied.

Task 2 builds on Task 1. Participants may choose to participate in only Task 1, or in both Task 1 and Task 2.

As training data for Task 1, text for 100 methods sections will be released with annotations for mentions of experimental design factors. As training data for Task 2, relations among experimental design factors will be annotated for a subset of the 100 methods sections.

For the test set, participants will be provided ~300 methods sections as text documents to test their IE approach for identifying experimental design factors and their relations. Participants will be evaluated on an unidentified subset hidden within the test set. Evaluation will be P/R/F1-measure on mentions of factors and relations.

Mailing List

Join the tac-srie group to subscribe yourself to the tac-srie@list.nist.gov mailing list (if not already subscribed): Registering to participate in a track does not automatically add you to the mailing list. If you were previously subscribed to the mailing list, you do not have to re-subscribe (the mailing list is for anyone interested in TAC SRIE, rather than specifically for TAC SRIE participants, and thus carries over from year to year).
