A logic process apparatus for composite graphs in a fixed layout document is provided in this invention. The apparatus includes a composite graph block extraction unit, for extracting composite graph blocks from the fixed layout document, a document parsing unit, for parsing the fixed layout document to obtain text primitives contained therein, a legend primitive extraction unit, for extracting legend primitives from the text primitives, a correlation detection unit, for detecting correlations between the composite graph blocks and the legend primitives, and a correlation storage unit, for storing the detected correlations. A logic process method for composite graphs in a fixed layout document is also provided.

Logic processing apparatus and logic processing method for composite graphs in fixed layout document

The present invention provides an apparatus for logically processing a composite graph in a formatted document, the apparatus comprising: a composite graph block extraction unit, used to extract a composite graph block in the formatted document; a document parsing unit, used to parse the formatted document to obtain a text element contained therein; a cutline element extraction unit, used to extract a cutline element from the text element; a correlativity detection unit, used to detect correlativity between the composite graph block and the cutline element; a correlativity storage unit, used to store the detected correlativity. The present invention also provides a method for logically processing a composite graph in a formatted document. According to the technical scheme disclosed in the present invention, it is easily achieve layout understanding of the composite graph in a graph-text mixed layout of the formatted document, so as to avoid a logical error.
