| - | - Aggregate and share note-type metadata from various sources: Karthik | + | - Continue discussion of NLP system evaluation across different sites |
| - | * 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. | + | - The NLP-WG will meet on second Wednesday of every month |
| - | * 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 | + | |
