1. A method for recognizing the structure of a delineated table region in an electronic document, comprising the steps of:

  • a) creating a binary tree using a hierarchical clustering of a plurality of words included in said table region;

    b) segregating a plurality of table columns using a breadth-first traversal algorithm;

    c) identifying column headers, if any, using a first heuristic algorithm; and

    d) identifying row headers, if any, using a second heuristic algorithm; and

    e) segregating at least one table row using a row determination algorithm.
