Abstract
Tables including cells can be extracted from an input document image, as objects and processed to be output in an XML format. The tables can be filtered based on one or more keywords, to reduce a number of the tables. The filtered tables that include the one or more keywords can be obtained. A query can be executed on the filtered tables, the query including one or more keys composed based on cell level information associated with the filtered tables. One or more cells among the cells can be identified based on the one or more keys. As a response to the query, the target content that corresponds to the one or more cells can be provided.
