on Challenges in Natural Language Processing for Clinical Data
New Tracks: System Usability and Novel Data Use
Tentative Timeline
Registration: began March 14, 2014
Training Data Release: began 1 May, 2014
Test Data Release: 1 July, 2014
Systems Due (Track 3 only): 1 September, 2014
Paper Submission (Track 4 only):1 September, 2014
Workshop: November 14, 2014
To register for these tracks, please contact i2b2nlp@albany.edu.
UPDATE: The 2014 Workshop Registration online form is now available. Please submit the form before November 14, 2014.
We are pleased to announce two new tracks, added in addition to the NLP tracks 1 (de-identification) and 2 (heart disease risk factors) for the 2014 shared task and workshop. For information on the NLP tracks of de-identification and heart disease risk factors, please click here.
The 2014 i2b2/UTHealth Challenge now introduces two additional tracks:
Track 3: Software Usability Assessment:
This is a new track introduced this year for testing the usability of software.
This track is meant to evaluate the i2b2 challenge software for how easily users learn and use the software to
achieve their goals.
The Software Usability Assessment Track is open to all current and prior i2b2 challenge participants who have developed systems on
any of the i2b2 datasets since 2006. To participate in this track, the participants are expected to provide the name(s) and link(s)
of their system(s). After evaluation, the comments of the evaluators will be provided to the participants, which should be
useful for improving the usability of the system.
Track 4: Novel Data Use: The data released for this 2014 i2b2 challenge Tracks 1 (de-identification) and 2 (heart disease risk factors) are unique among publicly available clinical data sets in that they represent longitudinal data selected by an MD for the purpose of identifying risk factors in a diabetic population. However, these data can be used to answer other questions on these patients. This Track is for participants who want to build on their existing systems or the systems developed for Tracks 1 and 2, in order to answer new questions with these data. Some example questions include (but are not limited to): Are the medications having the desired effect? Is the patient responding to treatment for their hypertension? Is the patient responding to treatment with their lipids? Is the patient experiencing an adverse effect from their medications? Are some risk factors are more highly correlated with CAD than others?
Participants are encouraged to define their own questions to ask of these data.
In addition, participants of this track can contribute visualizations on NLP output for Tracks 1 and 2, or provide novel de-identification methods. Note that this track uses data from Tracks 1 and 2 and will follow the same data release timeline as those tracks.
The data for the 2014 i2b2 Challenge is provided by Partners HealthCare. All records have been fully de-identified and manually annotated for risk factors related to diabetes and heart disease risk factors.
Data for the challenge is released under a Rules of Conduct and Data Use Agreement. Obtaining the data requires completing a registration, which started March 14, 2014. Training data was released on May 1, 2014 and is now available to registered users.
Evaluation Dates, File Formats, and Evaluation Metrics
Evaluation of software submitted to Track 3: Usability evaluation will be
performed with a relevant use case for the specific task and using
formal usability testing software. Usability evaluators will be students and staff affiliated with
the University Of Michigan Center for Managing Chronic Disease who have extensive experience working
with patient charts and patients with complex chronic diseases. The evaluation criteria and procedures
include:
- Quality of end user manual;
- Time/effort taken to install the software in a test environment and to execute an
install-validation demonstration task;
- Time/effort it takes to replicate the procedures that generated the results the authors
previously reported (if any);
- Time/effort it takes to replicate the procedures on a different corpus;
- Quality of coding and coding documentation.
Particpants in Track 3 are asked to email Dr. Anupama E. Gururaj (Anupama.E.Gururaj@uth.tmc.edu) the following information:
- Participant information (name, affiliation, and email) *
- Name of the system *
- URL for downloading the system *
- Manual(s) - any type of instructions for users to install and/or use the system
- Documentation - for continued development of the software
- Source codes - for open source systems
* denotes a required field
Track 4 will be evaluated on the basis of papers to be submitted to the organizing committee. Due to the open-ended nature of this track, there will be no system comparison or ranking. The aim is to demonstrate creative, clinically-relevant and varied uses of the Track 1 and Track 2 data. Therefore, papers describing novel and well-executed systems will be considered for publication in a journal special issue related to this shared task.
Participants in Track 4 are asked to submit a short paper describing their system and analyzing their performance. Papers should be in AMIA style and should not exceed five pages. Authors of top performing systems and of particularly novel approaches will be invited to present or demo their systems at the workshop. Submitted software can be presented at the final workshop in the form of a poster or live demo.
