Symmetric schema instantiation method for use in a case-based reasoning system

摘要

A method involves providing a parent schema, generating a plurality of distinct and domain-specific instantiations of the parent schema, user-validating at least two of the instantiations of the parent schema, and creating a symmetric schema by combining the user-validated instantiations of the parent schema. The parent schema and the instantiations of the parent schema may be user-provided or iteratively generated. The parent schema contains more than one tractable search spaces. Prior to user-validating the instantiations of the parent schema, they may be optimized using domain-specific knowledge. Additionally, one or more existing Boolean features in one or more cases of a case-based reasoning system may be replaced with the instantiations of the parent schema and non-zero weights for the cases may evolve that include the instantiations of the parent schema. The method may also include generating instantiations of the created symmetric schema.
