| + | * To define the syntax for storing phenotypes, two aspects can be considered: | ||
| + | - set of data elements or features on which an algorithm functions | ||
| + | - formulation of the phenotype definition | ||
| + | * In order to represent the NLP output, query-based phenotyping will be the first focus of the group. | ||
| + | * For machine-learning based algorithms, the NLP output will be accessed outside of the CDM | ||
| + | * Is ElasticSearch a good first step in this area? ES should be considered here as a tool more for cohort building and selection rather than phenotyping. For this purpose, it is a good starting point. | ||
| + | * Finding patients for clinical trials will be used as a usecase here. The ES could serve as an explorer for feature selection in the phenotyping process. | ||
| + | * Action item: Simple search set up for MT samples by next meeting by Min. | ||
| + | * Use MIMICII and MIMICIII as demo datasets for the tools being developed by the group | ||
