9. Goals of 2016
10. Change of meeting time

1. Minimal model presntation - Alex
2. Collect minimum set of modifiers for all clinical entities that support use of rule to derive clinical concepts: Alex
   • cTAKES is being run on clinical notes programmatically. Alex will present the minimal model in the next meeting.
3. Aggregate and share note-type metadata from various sources: Karthik
   • LOINC note type mapping would be a very useful resource. We should generate hierarchical representation of note-types as an ontology. Karthink will present his work to date at the next meeting.
   • Existing ontology for note types to be shared : Vanderbilt (Hua) and Regenstrief (Jon)
4. Simple search set up for MT samples: MinPresentation
   • Presentation
   • The interface being developed should present a summary with visualization for patients/notes.
   • We will add Boolean query options to improve the search
   • We will implement a Ranking algorithm
   • Assign fake patient ID's to the notes to generate the visualization portion.
   • Generate a program like Circe to define the patient cohort
   • Next steps: How to move the data from textual searches stored in a table outside of OMOP to the OMOP?
     • Structured searches from CDW and textual searches can be combined using existing strategies. Jon will share the slides of his presentation on combining data from different searches
     • Run NLP on the ElasticSearch to extract information
5. Wrappers for cTAKES and Metamap
6. Report on the WG - Hua will generate and share with the members for comments
7. The best ways to represent textual data need to be determined
