OntoCONDOR ontology

This ontology was developed to address the needs expressed by the CONDOR project.

The ontology was designed as an application ontology gathering all entities and relationships involved. It extends the OntoSPM ontology, a general-purpose ontology for Surgical Process Models designed in the context of the OntoSPM collaborative Action.

The choice of classes and the relationships that bind them derive from the functional needs expressed in CONDOR, namely mainly, the annotation of surgical videos: description of the actions that take place on surgical videos, leading mainly to naming:

  • the actors involved, and possibly specifying the hand involved
  • the objects affected by actions, in particular anatomical or pathological objects
  • the surgical instruments and materials used
  • the description of events such as bleeding or smoke that may affect the legibility of images, or events affecting the field of view
  • visibility of objects in images of the videos.

The ontology is organized as a set of files represented in OWL, the Web Ontology Language. OntoSPM and OntoCONDOR reused as much as possible existing ontological resources. Therefore, we adopted an organization in modules, in which the root application ontology (called OntoCONDOR) imports OntoSPM, which imports several extracts of existing ontologies.

These extracts, e.g. from the Foundational Model of Anatomy, the Units Ontology (UO), the Phenotype and Trait Ontology (PATO) were generated using the OntoFox tool, based on the MIREOT model. The overall integration of these disparate ingredients relied on the common philosophical ground provided by the Basic Formal Ontology (BFO version 23).

In terms of application, OntoCONDOR focuses on the two procedures considered in CONDOR, namely:

  1. ‘Endoscopic cholecystectomy’
  2. ‘Stomach gastric bypass in obesity surgery’.

Especially, it lists the various 'surgical procedure phases’ and the ‘surgical procedure steps’ involved in these surgical procedures.

The OntoCONDOR ontology can be freely downloaded and reused. Two zip files are provided.
