Method for assessing quality of open source projects

A server configured for determining one or more latent variables related to quality of a selected open source project, the server comprising a transceiver, a control unit and a memory,

• wherein the transceiver is configured to:
• retrieve, for each of one or more absolute features, a corresponding transform related to a respective probability distribution, wherein the corresponding transform is determined based on a multitude of open source projects, a first transform corresponding to a first absolute feature of the one or more absolute features being different than a second transform corresponding to a second absolute feature of the one or more absolute features, wherein the control unit is configured to execute:
• an extracting function, configured to extract open source project data related to the selected open source project from one or more databases,
• a first determining function, configured to determine one or more corresponding absolute feature values of one or more absolute features from the open source project data according to pre-set rules,
• a transforming function, configured to transform the one or more corresponding absolute feature values of the one or more absolute features into one or more absolute feature values corresponding to one or more relative features by using the corresponding transform of each absolute feature,
• a first weighting function, configured to weight the one or more corresponding relative feature values of the one or more relative features using a first set of weights, thereby forming one or more weighted relative feature values of the one or more relative features, and
• a second determining function, configured to determine one or more practice values of one or more practices, each of the one or more practices being related to a quality aspect of the selected open source project, as one or more sums of combinations of the one or more weighted relative feature values of the one or more relative features.
