TLDR
In this article, the authors propose to convert a text file which is represented with linear character strings into a hierarchical tree structure by analyzing index character strings corresponding to the chapters, paragraphs, and clauses in the main body of a document and automatically generating the tree-shaped logical structure.Abstract:
PURPOSE: To convert a text file which is represented with linear character strings into a hierarchical tree structure by analyzing index character strings corresponding to the chapters, paragraphs, and clauses in the main body of a document and automatically generating the tree-shaped logical structure. CONSTITUTION: A document read part 101 recognizes the characters of inputted document image data and the recognized document data are stored, document by document, in a document data storage part 103; and an index symbol analytic part 102 extracts index symbols and generate the logical structures of the documents from the meaning of the index symbols, and the generated logical structures are stored in the logical structure data storage part 104. A display control part 105 displays the logical structure of a document on a terminal device 106 with a screen according to the stored logical structure data. Consequently, the document file which is represented with linear character strings can be converted into the hierarchical tree structure. COPYRIGHT: (C)1992,JPO&Japioread more

Method and device for managing version of structured document
TL;DR: In this paper, the authors proposed a method to prevent the capacity of a document database from being make huge in the case of managing the version of the document by extracting the changed parts of both documents before and after editing, outputting the provided change information as structurally described differential information, displaying and preserving that structured differential information.
