Embodiments of the present invention disclose a method, computer program product, and system for generating a plan for document processing. A plurality of electronic documents are received from a data store. The plurality of electronic documents are analyzed. Textual data within the identified tabular data are identified, by performing a first natural language search of the analyzed plurality of electronic documents. Textual hints are generated, where the generated textual hints are mapped to a lookup set. References are identified, and a count of identified references are determined. A priority score is calculating based on the count of identified references. In response to receiving a priority score modifying value, a modified priority score is calculated. Ingestion plans are generated based on the modified priority score. Generated ingestion plans are communicated by the computer using the network.
