摘要
Disclosed is a method that generates a page frame structure associated with a sequentially-ordered set of pages, each being characterized by a set of page frame features. N-grams (sequence of n features) are computed from a set for n contiguous pages, and n-grams which are repetitive (Kleene cross) are selected. Pages matching the most frequent repetitive n-ram are grouped together under a new node, and a new sequence is created. The method is iteratively applied to this new sequence. The output is an ordered set of trees.
