Table 3 Summarized assessment of candidate ontological resources
From: TrhOnt: building an ontology to assist rehabilitation processes
Requirements | OpenGALEN | FMA | |
|---|---|---|---|
Coverage | It must cover at least the glenohumeral joint and its related body parts at great detail | ✓ | ✓ |
Understandability effort | Pruning supported by a physiotherapist will be needed to obtain a module about the glenohumeral joint. Thus the structure of the ontology in ontology development tools such as Protégé must be easy to understand | Too many classes defined at the top level, it makes it difficult to understand the actual hierarchy. Many classes have very long names, which are difficult to read. | ✓ |
Integration effort | It should be easy to integrate the candidate ontology with the ontology being developed. Moreover its implementation must adapt to the reasoner being used, and be logically satisfiable. In our case it is sufficient if the glenohumeral joint module is satisfiable. | ✓ | It includes unsatisfiable classes, but it is known that satisfiable modules can be obtained from it [19, 31] |
Reuse economic cost | It refers to the cost of accessing and using the ontology, including licensing costs. | 30 man-hours. No licensing fees. | 20 man-hours. No licensing fees. |
Reliability | The candidate ontology should come from reliable sources | ✓ | ✓ |
