* More discussion needed on whether to merge term_exists and term_temporal into one variable, or to leave them apart. | * More discussion needed on whether to merge term_exists and term_temporal into one variable, or to leave them apart. | ||
* Standardization of term_modifiers and values - led by Hua Xu: To define modifier list and normalized values for each modifier were the tasks. Initial review were from SHARPn modifiers (also used in cTAKES) and Wendy Chapman's group ([[https://github.com/Blulab-Utah/resource_ontologies/wiki]]). | * Standardization of term_modifiers and values - led by Hua Xu: To define modifier list and normalized values for each modifier were the tasks.

- | * Should certainty be merged with negation? - in instances where the negation is not about certainty (existential), it would be better to keep them separate. | + | * Should certainty be merged with negation? - in instances where the negation is not about certainty (existential/systemic), it would be better to keep them separate. Another point to think about is the utility of the categories (definite, probable, uncertain, probable negated, definite negated) and the ability of NLP systems to annotate the terms with them. Boolean negation is easier to annotate and handle. |
- | * | + | * Granularity of modifiers for subject - Family, Other, Patient may be sufficient for current datasets |
+ | * Generic/conditional modifier - Generic and Conditional as modifier may be acceptable. cTAKES does not support this currently. | ||
+ | * Course - possible values (very limited set) presented. Same as cTAKES. Default way of dealing with it could be to assign the ontology and the value from it. Open ended for now. Can be modified later based on use cases/usage. | ||
