This paper introduces a new framework for the organization of electronic books (e-books) and their corresponding authors using a multilayer self-organizing map (MLSOM). An author is modeled by a rich tree-structured representation, and an MLSOM-based system is used as an efficient solution to the organizational problem of structured data. The tree-structured representation formulates author features in a hierarchy of author biography, books, pages, and paragraphs. To efficiently tackle the tree-structured representation, we used an MLSOM algorithm that serves as a clustering technique to handle e-books and their corresponding authors. A book and author recommender system is then implemented using the proposed framework. The effectiveness of our approach was examined in a large-scale data set containing 3868 authors along with the 10500 e-books that they wrote. We also provided visualization results of MLSOM for revealing the relevance patterns hidden from presented author clusters. The experimental results corroborate that the proposed method outperforms other content-based models (e.g., rate adapting poisson, latent Dirichlet allocation, probabilistic latent semantic indexing, and so on) and offers a promising solution to book recommendation, author recommendation, and visualization.

September 14, 2000, is a date which will live in, well, "nonfamy," if I may be permitted such a neologism. That day, Microsoft released Windows Millennium Edition, its most forgettable operating system. It was also the day I posted the entry p-book to my Word Spy site, along with the following prognostication: "Within a few years, using the word 'book' without any kind of modifier will be confusing because people won't know if you?re talking about a book printed on paper or one that's printed on electrons (so to speak). So I predict that 'p-book'...will become a common noun that will help us distinguish between the paper and electronic formats." · For a while it looked like I couldn't have been more wrong. The number of citations for "p-book" (as well as "pbook") in the Nexis media database went from 20 in 2000 and 19 in 2001 to just 1 in 2003 and 2 in 2004. But as e?books have become more popular, the word p-book has been showing renewed signs of life, with 20 citations in 2010, 24 in 2011, and 28 in 2012. · Language prediction is a mug's game, but it's certain that digital books (as opposed to printed analog books) are here to stay. Sales of e-books (also known as ebooks or eBooks; there is much hand-wringing in the industry over the correct spelling) have slowed down recently, but they remain the fastest growing (or, for some companies, the only growing) segment of the publishing industry. The past few years have seen a steady increase in the number of writers?amateurs as well as professionals?who are getting into digital publishing (or e-publishing). For many writers, breaking into DIY publishing is a simple matter of saving a word processing document as a PDF, then putting up that file on a website along with a PayPal donation form.
