-        - 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 system allows for comparison ​of configs across different sites
-        - the notes were processed from eMERGE cohort at Columbia with about 60,000 notes encompassing 1700 patientsThe original patient number was 3200+        - Vojtech also has looked into using LOINC ontology for note types{{:​projects:​workgroups:​loinc_note_types_marshall_clinic.pdf|}} 
-        - In theorya set containing the combination ​of minimal modifiers can be generated. Practically,​ can we trust the data enough ​to add it into OHDSI tables? - only highest confidence data (with maximum PPV) should be added to the tables.+        - With reference to standard note typesone of the suggestions was to use it in the database for the output of the NLP system. 
 +        - The note table in the OMOP CDM has a note type field with about 10 or so note types 
 +        - 
         - Next steps:         - Next steps:
-          - Look at the note sections to determine the errors+          - Comparison of what aspects of LOINC is being used across different institutions
-          - Work with Sunny to generate ​the NLP outputs for the phenotyping data +          - One of the deliverable is to build a system that can map the institutional note type to the LOINC note types. 
-          - Evaluate by comparisons with structured data +          - Update ​the note type field of the note table in OMOP CDM. Should ​subset of LOINC document types be used for this purpose? this would depend ​on the real-world data from various ​institutions. 
-          - Make the system more robust +          - Ontologies such as CP, ICD-9 etc. that include more clinical terminologies should also be explored.
-          - Generate a protocol and/or annotation guidelines +
-          - Share the data as Gold standard with manually annotated CUIs +
-          - Alex's script is to be tried on different datasets and evaluated across notes from different ​institutions +
-          - Identify minimal set of notes to work with when recommending to the OHDSI community +
-          ​Identify sets of concepts ​that are not reliable - negation is a very good example of this idea. +
-          - Continue discussion of NLP system evaluation across different sites+
