Abstract

Portable document format (PDF) is a common output format for electronic documents. Most PDF documents are untagged and do not have basic high-level document logical structural information, which makes the reuse or modification of the documents difficult. We developed techniques that identified logical components on a PDF document page. The outlines, style attributes and the contents of the logical components were extracted and expressed in an XML format. These techniques could facilitate the reuse and modification of the layout and the content of a PDF document page.

Keywords

Document Image Text Line Text Segment Text Block Portable Document Format 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
