Abstract

ABSTRACT The task of extracting document structures from a digital e-book is difficult and is an active area of research. On the other hand, many e-books already have a table of contents (TOC) at the beginning of the document. This may lead us to believe that adding bookmarks into digital document (e-book) based on the existing TOC would be trivial. In this paper, we highlight the challenges involved in this task of automatically adding bookmarks to an existing e-book based on the TOC that exists within the document. If we are able to reliably identify the specific locations of each TOC entry within the document, the algorithms can be easily extended to identify document structures within e-books that have TOC. We describe a tool we have built called Booky that tries to add automatic PDF bookmarks to existing PDF based e-books as they have TOC as part of the document content. The tool addresses most of the challenges that have been identified while still leaving a few tricky scenarios still open.

从电子书的TOC条目生成书签的挑战

从电子书中提取文档结构是一个困难的任务，也是一个活跃的研究领域。另一方面，许多电子书在文档的开头已经有了目录(TOC)。这可能会导致我们认为，在基于现有TOC的数字文档(电子书)中添加书签是微不足道的。在本文中，我们重点介绍了基于文档中存在的TOC自动向现有电子书添加书签的任务所涉及的挑战。如果我们能够可靠地识别文档中每个TOC条目的具体位置，那么算法可以很容易地扩展到识别具有TOC的电子书中的文档结构。我们描述了一个我们建立的叫做Booky的工具，它试图将自动PDF书签添加到现有的基于PDF的电子书中，因为它们将TOC作为文档内容的一部分。该工具解决了已经确定的大多数挑战，同时仍然留下一些棘手的场景仍然开放。
