Embodiments of the present invention disclose a method for processing tabular data. In various embodiments, an electronic document is received through a network, along with associated metadata. A plurality of table markers, or tabular data markers, are identified, in response to analyzing the received electronic document for said markers. References and citations associated with the plurality of tabular data markers are identified. A graphical representation of the relationship between identified tabular data markers and the identified references is generated. A uniqueness score is calculated, based on the generated graph and an ingestion plan is generated for the received electronic documents based on the calculated uniqueness score value.
