====== Action items updates: ======

  * Mapping of Note Types to LOINC/standard vocabulary – Karthik Natarajan, Ruth Reeves, and Jon Duke
        * bigrams shared by Jon
        * {{ :projects:workgroups:report_type_tags_for_review.xlsx |}}, 
        * {{ :projects:workgroups:report_bigrams_with_counts.xlsx |}}, 
        * need help to look through the tags and determine the appropriate tags/tag level, 
        * use published literature to look at tags granularity
        * Broad categorization of tags (from LOINC, maybe?)
  * Landscape Analysis of section identifier systems and proposal of a standard terminology for use – Hua Xu and Karthik Natarajan 
  * Mapping of CUIs to standard terminology – Juan Banda, need to add link to Juan's repo in the OHDSI NLP repo
  * Standardization of term_modifiers and values – Hua Xu
  * Evaluate and revise textual CDM tables by sharing practical issues and lessons learnt during ETL for processing textual data into CDM – Ruth Reeves: discussion about modifiers representation in the notes_NLP table, potentially have a separate modifiers table? key-value pairs of modifiers and their allowed values
  * Develop tools (within Atlas) to facilitate uses of NLP data for cohort building/phenotyping : Collaborate with eMERGE consortium
  * Conduct cross-site studies that use textual data
  * Continue developing other NLP resources
