Abstract
The basic idea of re-flowable document understanding and automatic typesetting is to generate logical documents by judging the hierarchical relationship of physical units and logical tags based on the identification of logical paragraph tags in re-flowable document. In order to overcome the shortages of conventional logical structure reconstruction methods, a novel logical structure reconstruction method of re-flowable document based on directed graph is proposed in this paper. This method extracts the logical structure from the template document and then utilizes directed graph’s single-source shortest path algorithm to filter out redundant logical tags, thus solving the problem of logical structure reconstruction of a document. Experimental results show that the algorithm can effectively improve the accuracy of logical structure recognition.
