Abstract
Described herein are systems and methods for extracting borderless checkbox tables from electronic documents. A server detects checkboxes in a textual electronic document. The server extracts text blocks from the textual electronic document. The server identifies table headers corresponding to a borderless checkbox table in the textual electronic document based on the text blocks. The server determines a table boundary corresponding to the borderless checkbox table based on the table headers. The server identifies table rows and table columns corresponding to the borderless checkbox table based on the table boundary and the checkboxes. The server identifies table cells corresponding to the borderless checkbox table based on the table rows and the table columns. The server generates a data structure comprising data representing the borderless checkbox table based on at least the table cells and the checkboxes.
