| - | - Minimal model presentation - Alex {{:projects:workgroups:ohdsi_nlp_wg_yahi.pdf|}} | + | - Note-type mapping Presentation – Karthik {{:projects:workgroups:ohdsi-nlp-wg1457551276.mp4|}} |
| - | - 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. | + | - INYP terminology services provides clinical document browser based on LOINC ontology for clinical notes. The paper describing the system is published and the pdf is attached. {{:projects:workgroups:loinc_note_mapping_paper.pdf|}} |
| - | - the notes were processed from eMERGE cohort at Columbia with about 60,000 notes encompassing 1700 patients. The original patient number was 3200. | + | - the system allows for comparison of configs across different sites. |
| - | - In theory, a 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. | + | - Vojtech also has looked into using LOINC ontology for note types. {{:projects:workgroups:loinc_note_types_marshall_clinic.pdf|}} |
| + | - With reference to standard note types, one 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 a subset of LOINC document types be used for this purpose? this would depend on the real-world data |
| - | - Make the system more robust | + | - existing ontologies from Vanderbilt - Hua - {{:projects:workgroups:document-types.zip|}} |
| - | - Generate a protocol and/or annotation guidelines | + | |
| - | - Share the data as a 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 | + | |
| - | - The NLP-WG will meet on second Wednesday of every month | + | |
