Minimal model presentation - Alex
the model is based on the SHARE-N model and adapted to the current data structure. This model incorporates other semantic types and all of the modifiers are not available in cTAKES yet.
the notes were processed from eMERGE cohort at Columbia with about 60,000 notes encompassing 1700 patients. The original patient number was 3200.
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.
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)
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
Wrappers for cTAKES and Metamap
Report on the WG - Hua will generate and share with the members for comments
The best ways to represent textual data need to be determined
