Abstract
According to a present invention embodiment, a system supplements structured information within a data system for entities based on unstructured data. The system analyzes a document with unstructured data and extracts attribute values from the unstructured data for one or more entities of the data system. Entity records with structured information are retrieved from the data system based on the extracted attribute values. Entity references for corresponding entities of the data system are constructed based on a comparison of the retrieved entity records and the extracted attribute values. The entity references are linked to the corresponding entities within the data system, wherein the entity references include extracted attributes from the unstructured data for corresponding linked entities. Embodiments of the present invention further include a method and computer program product for supplementing structured information within a data system for entities based on unstructured data in substantially the same manner described above.
