The overarching long-term vision of our research is to create novel technologies for processing clinical free text. Such technologies will enable sophisticated and efficient indexing, retrieval and data mining over the ever increasing amounts of electronic clinical data. Processing free text poses a number of challenges to which the fields of Artificial intelligence, natural language processing and computer science in general have made advances. Methods for processing free text are informed by linguistic theory combined with the power of statistical inferencing. A key component to the next step, natural language understanding, is discovering events and their relations on a timeline. Temporal relations are of prime importance in biomedicine as they are intrinsically linked to diseases, signs and symptoms, and treatments. Understanding the timeline of clinically relevant events is key to the next generation of translational research where the importance of generalizing over large amounts of data holds the promise of deciphering biomedical puzzles.  
 
The overarching long-term vision of our research is to create novel technologies for processing clinical free text.

A key component to the next step, natural language understanding, is discovering events and their relations on a timeline. Temporal relations are of prime importance in biomedicine as they are intrinsically linked to diseases, signs and symptoms, and treatments. Understanding the timeline of clinically relevant events is key to the next generation of translational research where the importance of generalizing over large amounts of data holds the promise of deciphering biomedical puzzles.  
  
The goal of our current proposal is to discover temporal relations from clinical free text through achieving four specific aims:
+
The best methods have been/will be released as part of the cTAKES (ctakes.apache.org) for the larger community to use and contribute to. We will test the methods against biomedical queries.
 
 
Specific Aim 1: Develop (1) a temporal relation annotation schema and guidelines for clinical free text based on TimeML, which will require extensions to Treebank, PropBank and VerbNet annotation guidelines to the clinical domain, (2) an annotated corpus (500K words of clinical narrative) following the temporal relations schema with additions to Treebank, PropBank and VerbNet, (3) a descriptive study comparing temporal relations in the clinical and general domains.
 
 
 
Specific Aim 2: Extend and evaluate existing methods and/or develop new algorithms for temporal relation discovery in the clinical domain. Component-level evaluation
 
 
 
Specific Aim 3: Integrate best method and/or a variety of methods for temporal relation discovery into Apache cTAKES (ctakes.apache.org) and release as open source annotators in the pipeline. Functional testing. Dissemination activities.
 
 
 
Specific Aim 4: System-level evaluation. Test the functionality of the enhanced Apache cTAKES (ctakes.apache.org) on translational research use cases, e.g. the progression of colon cancer as documented in clinical notes and pathology reports, the progression of brain tumor as documented in radiology reports.
 
 
 
The methods we will use for the temporal relation discovery are based on machine learning, e.g., Support Vector Machine technology. Such methods require the annotation of a reference standard from which the computations are derived. The best methods will be released as part of the cTAKES for the larger community to use and contribute to. We will test the methods against biomedical queries.

'''Step 2''': Mayo Legal Contracts Office will send you a partially filled-out DUA for you to add information to, and for you to have signed by your site's official signatory.  
+
The corpus is released to an established or junior NLP investigator, formally associated with an institution; thus it is not released to a student. However, all students working with the investigator can have full access to the corpus under the DUA of the investigator. The investigator is urged to have the students work on the corpus on workstations that stay within the laboratory space of the investigator.  
  
'''Step 3''': After you return the DUA to Mayo Clinic, Mayo Legal Contracts Office will complete the DUA and send you a copy of the fully executed DUA, and ClinicalNLP@mayo.edu will be copied on the email.
+
The steps for obtaining a DUA are:
 
 
'''Step 4''': A Mayo Clinic NLP investigator will arrange to talk with you.
 
 
 
'''Step 5''': Once the DUA is complete and you have talked with a Mayo Clinic NLP investigator, ClinicalNLP@mayo.edu will send you instructions for obtaining the corpus via the secure downloading mechanism

# A THYME investigator will send your principal investigator a DUA for you to add information to, and for you to have signed by your site's official signatory. The THYME investigator will provide instructions for returning the signed and completed DUA.
 +
# When you return the DUA, a THYME investigator will arrange to talk with your principal investigator. Of note, the discussion must be with the lab's principal investigator, not a student/postdoc/administrator. Topics that will be addressed include allowable uses of the data and proper security measures.

# Once the DUA is complete and a THYME investigator has confirmed your understanding of the DUA, you will be sent instructions for obtaining the corpus via a secure downloading mechanism. -->

Welcome to the THYME project

Welcome to the Temporal Histories of Your Medical Event (THYME) project (THYME is pronounced [taim]).

The overarching long-term vision of our research is to create novel technologies for processing clinical free text. Such technologies will enable sophisticated and efficient indexing, retrieval and data mining over the ever increasing amounts of electronic clinical data. Processing free text poses a number of challenges to which the fields of Artificial intelligence, natural language processing and computer science in general have made advances. Methods for processing free text are informed by linguistic theory combined with the power of statistical inferencing. A key component to the next step, natural language understanding, is discovering events and their relations on a timeline. Temporal relations are of prime importance in biomedicine as they are intrinsically linked to diseases, signs and symptoms, and treatments. Understanding the timeline of clinically relevant events is key to the next generation of translational research where the importance of generalizing over large amounts of data holds the promise of deciphering biomedical puzzles.

The best methods have been/will be released as part of the cTAKES (ctakes.apache.org) for the larger community to use and contribute to. We will test the methods against biomedical queries.


Funding

Phase 1 of the project (2010-2014) was supported by THYME R01LM010090 from the National Library Of Medicine and in part by the i2b2 project (U54LM008748 from the National Library of Medicine).

Phase 2 (2015-2018) and Phase 3 (2019-2023) are supported by THYME R01LM010090 from the National Library Of Medicine.

THYME Gold Standard Annotations

Annotation layers are treebank and propbank annotations as well as temporal annotations for events, temporal expressions and temporal relations.

Annotation guidelines

  • i2b2 Simplified THYME Guidelines (PDF) The guidelines provided to the organizers of the 2012 Temporal relations i2b2 challenge for consideration during planning. They reflect an earlier stage of our guidelines.

Tool for viewing the gold standard annotations - Anafora

We developed a web-based annotation tool. It is open source and available at https://github.com/weitechen/anafora. Use it to view the THYME annotations. Citation for the tool is:

THYME Software

The THYME system is available as part of Apache cTAKES at http://ctakes.apache.org/

Demo of the system: ctakes.apache.org -> get started -> demos -> ctakes-temporal (http://alt.qcri.org/semeval2016/task12/)

We have developed a visualization tool (THYME viz tool) available in Apache cTAKES sandbox. A prototype and details of the THYME vizualization tool was presented by Sean Finan at several annual workshops:
