Book Description
Seminar paper from the year 2006 in the subject English Language and Literature Studies - Linguistics, grade: keine, LMU Munich (Department für Anglistik und Amerikanistik), course: Internet Communication, language: English, abstract: The communication by email has become one of the most important means of communication in cooperate and private. An internet user is constantly confronted by mass emails containing undesired information. Spam, defined as bulk unsolicited emailing, generally commercial in nature, and predominately fraudulent. Spam causes high charges and damages. Nucleus Research announced that the spam epidemic is costing US businesses $712 per employee each year in lost worker productivity. As a result, users are spending 16 seconds identifying and deleting each spam e-mail, which translates into an annual cost of $70 bln to all US businesses. Looking at the total e-mail traffic, Nucleus estimates that at least 90% of e-mail reaching corporate servers is spam. The average user receives 21 spam messages to their inbox each day. (Moskalyuk 2007) Regardless of the inefficient time spent, there are further costs caused by spam, such as (cf Filterpoint 2008): · Deleted emails remain stored in the trash folder. · Higher storage costs through higher server expenses. · Higher bandwith essential to store the spam mails. · Time spent by IT staff for anti-spam measures. · Recovery costs after a virus attack. Various experts provide a spam calculator that enables to determine the approximate annual costs for an enterprise created by spam. (Gibbs 2003, Commtouch 2007) The calculator introduced by Gibbs differentiates productivity, connectivity, storage and support costs. This Spam Cost Analysis Model can be found in appendix 1 of this work. In this work different types of spam in general and in specific will be pointed out and characterized. Measures against unsolicited emails will be reviewed. First I start with the definition of spam and where it comes from, followed with the spam history. Then I briefly list the most common categories and variants of spam used. The next step will be the revision of a present situation captured by Commtouch and Symantec, as well as statistics on the information learned through spam monitoring during the last few months, with the examples of its usage. I conclude with an overview of spam solutions offered and point out further research topics in the area.

Book Description
What spam is, how it works, and how it has shaped online communities and the Internet itself. The vast majority of all email sent every day is spam, a variety of idiosyncratically spelled requests to provide account information, invitations to spend money on dubious products, and pleas to send cash overseas. Most of it is caught by filters before ever reaching an in-box. Where does it come from? As Finn Brunton explains in Spam, it is produced and shaped by many different populations around the world: programmers, con artists, bots and their botmasters, pharmaceutical merchants, marketers, identity thieves, crooked bankers and their victims, cops, lawyers, network security professionals, vigilantes, and hackers. Every time we go online, we participate in the system of spam, with choices, refusals, and purchases the consequences of which we may not understand. This is a book about what spam is, how it works, and what it means. Brunton provides a cultural history that stretches from pranks on early computer networks to the construction of a global criminal infrastructure. The history of spam, Brunton shows us, is a shadow history of the Internet itself, with spam emerging as the mirror image of the online communities it targets. Brunton traces spam through three epochs: the 1970s to 1995, and the early, noncommercial computer networks that became the Internet; 1995 to 2003, with the dot-com boom, the rise of spam's entrepreneurs, and the first efforts at regulating spam; and 2003 to the present, with the war of algorithms—spam versus anti-spam. Spam shows us how technologies, from email to search engines, are transformed by unintended consequences and adaptations, and how online communities develop and invent governance for themselves.

Book Description
Schwartz explores spam--unwanted e-mail messages and inappropriate news articles--and what users can do to prevent it, stop it, or even outlaw it. "Stopping Spam" provides information of use to individual users (who don't want to be bothered by spam) and to system, news, mail, and network administrators (who are responsible for minimizing spam problems within their organizations or service providers).

Book Description
New York Times bestseller! From New York Times bestselling author Cal Newport comes a bold vision for liberating workers from the tyranny of the inbox--and unleashing a new era of productivity. Modern knowledge workers communicate constantly. Their days are defined by a relentless barrage of incoming messages and back-and-forth digital conversations--a state of constant, anxious chatter in which nobody can disconnect, and so nobody has the cognitive bandwidth to perform substantive work. There was a time when tools like email felt cutting edge, but a thorough review of current evidence reveals that the "hyperactive hive mind" workflow they helped create has become a productivity disaster, reducing profitability and perhaps even slowing overall economic growth. Equally worrisome, it makes us miserable. Humans are simply not wired for constant digital communication. We have become so used to an inbox-driven workday that it's hard to imagine alternatives. But they do exist. Drawing on years of investigative reporting, author and computer science professor Cal Newport makes the case that our current approach to work is broken, then lays out a series of principles and concrete instructions for fixing it. In A World without Email, he argues for a workplace in which clear processes--not haphazard messaging--define how tasks are identified, assigned and reviewed. Each person works on fewer things (but does them better), and aggressive investment in support reduces the ever-increasing burden of administrative tasks. Above all else, important communication is streamlined, and inboxes and chat channels are no longer central to how work unfolds. The knowledge sector's evolution beyond the hyperactive hive mind is inevitable. The question is not whether a world without email is coming (it is), but whether you'll be ahead of this trend. If you're a CEO seeking a competitive edge, an entrepreneur convinced your productivity could be higher, or an employee exhausted by your inbox, A World Without Email will convince you that the time has come for bold changes, and will walk you through exactly how to make them happen.

Book Description
This book discusses email spam detection and its challenges such as text classification and categorization. The book proposes an efficient spam detection technique that is a combination of Character Segmentation and Recognition and Classification (CSRC). The author describes how this can detect whether an email (text and image based) is a spam mail or not. The book presents four solutions: first, to extract the text character from the image by segmentation process which includes a combination of Discrete Wavelet Transform (DWT) and skew detection. Second, text characters are via text recognition and visual feature extraction approach which relies on contour analysis with improved Local Binary Pattern (LBP). Third, extracted text features are classified using improvised K-Nearest Neighbor search (KNN) and Support Vector Machine (SVM). Fourth, the performance of the proposed method is validated by the measure of metric named as sensitivity, specificity, precision, recall, F-measure, accuracy, error rate and correct rate. Presents solutions to email spam detection and discusses its challenges such as text classification and categorization; Analyzes the proposed techniques’ performance using precision, F-measure, recall and accuracy; Evaluates the limitations of the proposed research thereby recommending future research.
