Abstract

A method of automated document structure identification based on visual cues is disclosed herein. The two dimensional layout of the document is analyzed to discern visual cues related to the structure of the document, and the text o f the document is tokenized so that similarly structured elements are treated similarly. The method can be applied in the generation of extensible mark-up language files, natural language parsing and search engine ranking mechanism s.

Claims (13)

1. A method of creating a document structure model of a computer parsable document having contents on at least one page, the method comprising:
identifying the contents of the document as segments having defined characteristics and representing structure in the document;
creating tokens to characterize the content and structure of the document, each token associated with one of the at least one pages based on the position of each segment in relation to other segments on the same page, each token having characteristics defining a structure in the document determined in accordance with the structure of the page associated with the token; and creating the document structure model in accordance with the characteristics of the tokens across all of the at least one pages of the document.
2. The method of claim 1, wherein the computer parsable document is a page description language file, and wherein the step of identifying the contents of the document includes the step of converting the page description language to a linearized, two dimensional format.
3. The method of claim 1, wherein a segment type for each segment is selected from a list including text segments, image segments and rule segments to represent character based text, vector and bitmapped images and rules respectively.
4. The method of claim 3, wherein the text segments represent strings of text having a common baseline.
5. The method of claim 1, wherein the characteristics of the tokens define a structure selected from a list including candidate paragraphs, table groups, list mark candidates, Dividers, and Zones.
6. The method of claim 5, wherein one token contains at least one segment, and the characteristics of the one token are determined in accordance with the characteristics of the contained segment.
7. The method of claim 1, wherein one token contains at least one other token, and the characteristics of the container token are determined in accordance with the characteristics of the contained token.
8. The method of claim 1, wherein each token is assigned an identification number which includes a geometric index for tracking the location of tokens in the document.
9. The method of claim 1 wherein the document structure model is created using rules based processing of the characteristics of the tokens.
10. The method of claim 5 wherein at least two disjoint Zones are represented in the document structure model as a Galley.
11. The method of claim 5 wherein the candidate paragraph is represented in the document structure model as a structure selected from a list including titles, bulleted lists, enumerated lists, inset blocks, paragraphs, block quotes, tables, footers, header, and footnotes.
12. A system for creating a document structure model using the method of claim 1, the system comprising:
a visual data acquirer for identifying the segments in the document;
a visual tokenizer connected to the visual data acquirer for receiving the identified segments, for creating the tokens characterizing the document, the visual tokenizer; and a document structure identifier for creating the document structure model based on the tokens received from the visual tokenizer.
13. The system of claim 12 further including a translation engine for reading the document structure model created by the document structure identifier and creating file in a format selected from a list including Extensible Markup Language, Hypertext Markup Language and Standard Generalized Markup Language, in accordance with the content and structure of the document structure model.
