Abstract: In various example embodiments, a semantic modeling server includes a semantic model and an inductive logic programming module. The semantic module includes underlying data that defines one or more characteristics of a part to be manufactured. The inductive logic programming module is provided with positive and negative examples of a feature to be identified and part data that defines the part to be manufactured. Given the examples of the feature and the semantic model, the inductive logic programming module determines various rules that can be used to identify whether the provided part data includes the feature defined by the semantic model. Using the determined rules the inductive logic programming module then identifies instances of the feature associated with the semantic model within the provided part data. The inductive logic programming can then be iteratively executed with the semantic model to refine the determined rules.
