Auto-mapping between source and target models using statistical and ontology techniques

A system for mapping data within a data source to a target data model comprising:

• a computer system including at least one processor configured to:
• determine an identifier for each data object of the data source based on the data within that data object, wherein the identifier indicates a corresponding entity within a source ontology of a data model of the data source to which that data object belongs, wherein the source ontology includes a plurality of entities and relations between those entities, and wherein the determining the identifier includes:
• identifying for ouch data a partition of one or more entities in the source ontology including a greatest amount of data from that data object;
• and
• determining the identifier for each data object based on the identified partition associated with that data object;
• compare the determined identifiers for the data objects of the data source to a target ontology of the target data model to determine mappings between the data objects of the data source and the target data model;
• and
• extract data objects from the data source for the target data model in accordance with the mappings.

A computer program product for mapping data within a data source to a target data model comprising:

• a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising computer readable program code configured to:
• determine an identifier for each data object of the data source based on the data within that data object, wherein the identifier indicates a corresponding entity within a source ontology of a data model of the data source to which that data object belongs, wherein the source ontology includes a plurality of entities and relations between those entities, and wherein the determining the identifier includes:
• identifying for each data object a partition of one or more entities in the source ontology including a greatest amount of data from that data object;
• and
• determining the identifier for each data object based on the identified partition associated with that data object;
• compare the determined identifiers for the data objects of the data source to a target ontology of the target data model to determine mappings between the data objects of the data source and the target data model;
• and
• extract data objects from the data source for the target data model in accordance with the mappings.
