Data unification device and method for unifying unstructured data objects and structured data objects into unified semantic objects

A data unification device for unifying data objects includes a retrieving entity, a first providing entity, a second providing entity, and an assembling entity. The retrieving entity is configured to retrieve unstructured data objects from a number of unstructured knowledge bases and structured data objects from a number of structured knowledge bases. The first providing entity is configured to provide a number of syntactic frames for each retrieved data object, wherein each syntactic frame include a syntactic concept, a syntactic concept-instance, and a syntactic concept-instance relationship. The second providing entity is configured to provide a number of semantic frames for each retrieved data object, wherein each semantic frame includes a semantic concept, a semantic concept-instance, and a semantic concept-instance relationship. The assembling entity is configured to assemble, for each retrieved data object, the provided syntactic frames and the provided semantic frames to one semantic object.
