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. 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.
