Welcome to our website for the evaluation of ontology metrics. The
evaluation of the metrics is carried out for a corpus of ontologies and
has two main steps: Calculation of the values of the metrics using the
corpus of ontologies, and analysis of the metrics.
The corpus of ontologies
The ontologies must be publicly available in OBO or OWL format.
The corpus of ontologies has to be provided as a list of
Some sample corpus are provided in our Examples
Calculating the metrics
19 metrics are calculated for each ontology using the OQuaRE web
The process discards ontologies that cannot be processed or that
contain unsatisfiable classes. Such aspects are reported in the
log of the process
The metrics for corpora with less than 5 ontologies will be
obtained, but the results won't be processed by the analysis
The calculation of the metrics is time consuming for large
ontologies and corpora, so a link to the results will be sent by
email to the user as soon as the task is completed.
The result is a ZIP file which contains the log of the process,
an XML file per ontology with the values of the metrics and a CSV
that holds a table of the values of each metric for each ontology.
Some sample files are provided in our Examples
Evaluating the metrics
The correlations between the 19 metrics, their stability and
goodness of their classifications will be evaluated.
Metrics with less than 5 different measurements will not be
included in the evaluation. This will be reported in the log
The input is the ZIP file generated in the previous step
The evaluation of the metrics does not require much time, but
the user has the possibility of getting a link to the results by
email as soon as the task is completed.
The result is a ZIP file which contains a series of files: the
log, 2 CSV data files with the stability and silhouettes for
each metric, the image of the global stability of the metrics in
different image formats and 19 PDF files with the images
corresponding to the data files.
