We have created and implemented various ontology for health informatics usage.

CNTRO (Clinical Narrative Temporal Relation Ontology) allows temporal information of clinical data to be semantically annotated and queried, and use inference to expose new temporal features and relations based on the semantic assertions and definitions of the temporal aspects in the ontology.

Time Event Ontology (TEO) has been developed in order to provide a formal conceptualization of temporal structures in both structured data and textual narratives. For more details, visit Time Event Ontology.


CNTRO TimeLine API: The CNTRO Timeline library is a Java library. This library is intended to be used by developer and analysts who want to integrate this library in their workspace to compute temporal information about clinical events. For more details, visit Timeline API Library.
