A method (10) of automatically constructing probabilistic graphical models from a source of data for user selection includes: providing in memory a predefined catalog (122) of graphical model structures based on node types and relations among node types;selecting by user input specified node types and relations;automatically creating(12, 14), in a processor, model structures from the predefined catalog of graphical model structures and the source of data based on user selected node types and relations; automatically evaluating(18), in the processor, the created model structures based on a predefined metric;automatically building, in the processor, a probabilistic graphical model for each created model structure based on the evaluations;calculating a value of the predefined metric for each probabilistic graphical model;scoring each probabilistic graphical model based on the calculated metric; and presenting to the user each probabilistic graphical model with an associated score for selection by the user. |
