Dejean and Meunier used four methods for extracting book structure including (i) detecting and parsing TOC pages (ii) parsing index pages (iii) using classical methods for TOC detection and (iv) using trailing page whitespace methods.

For this purpose, several IE methods have been devised, which include using book layout analysis for extracting TOC using resurgence software for detecting different parts of books by considering typographical positions and book content instead of TOC to detect parts, chapters, sections, and pages using rule-based methods for extracting TOC from books that are having TOC pages, and SVM-based methods for books that are without TOC pages and using layout analysis to identify TOC and other functional regions including chapters, paragraphs, and notes in books.
Information Extraction (IE) can be very tricky when applied to digitized books for extracting structure and layout information including TOC. Compared with the most of other methods used to optimize workflow, this method is simpler, more efficient, and more suitable for e-book format conversion. This research introduces the traditional IE analytical techniques to the workflow optimization of e-book conversion. The simulation results show that, under similar circumstance, both quantity and quality of the products is improved after optimization, which indicates the optimization method is effective.
In order to validate the optimization effect, the workflow before and after optimization are generated and implemented by the ExtendSim® simulation software. Then the workflow is analyzed by using 5W1H (why, who, what, where, when, how) methodology and optimized with ECRSI (Eliminate, Combine, Rearrange, Simplify and Increase) principles.

**How Do I Convert a PDF to an ePUB or an eBook?**ĭownload PDF to ePUB Converter for free and install it on your computer.This paper aims to provide an optimization method of workflow for publishing houses and electronic book (e-book) researches in the field of digital publishing.īased on the researches of publishing houses in Beijing, the present conversion workflow is illustrated by using a functional modeling methodology. To make these textbooks more appealing and flexible in terms of screen size, converting them to EPUB, DOCX, DOC, HTML, EML, RTF, JPEG, PNG, GIF, TXT, XLSX, and XLS files is a great option, as the EPUB file adapts to any type of device, including mobile phones, computer screens of any size, and will provide readers with an experience similar to reading a physical book. Most educational publishers now save all textbooks in PDF format in their databases, but you may find that the PDF textbooks do not always fit the screen size of the electronic device. Our top picks cater to all types of users. It makes no difference what operating system you're running. However, with the correct equipment, you can finish the job in no time. However, in order to read an e-book on most e-readers, such as the Amazon Kindle and the Barnes & Noble Nook, you must first convert it to EPUB format.Ī PDF to EPUB conversion may appear daunting at first. A PDF file format is ideal for making and reading e-books.
