The Internet’s current architecture de-couples the cost of sending traffic from the consequences of sending traffic. Its open nature allows anyone to initiate a connection with minimal authentication. These factors account for the excessive consumption caused by spam in the email system and other service areas. At the network layer, resource consumption caused by spam is analogous to Distribute...

Presence of spam tweets in a datasetmay affect the choices of feature selection, algorithm formulation, and system evaluation for many applications. However, most existing studies have not considered the impact of spam tweets. In this paper, we study the impact of spam tweets on hashtag recommendation for hyperlinked tweets (i.e., tweets containing URLs) in HSpam14 dataset. HSpam14 is a collect...

Email spam is one of the unsolved problems of the today's Internet, annoying individual users and bringing financial damage to companies. Among the approaches developed to stop spam emails, filtering is a popular and important one. Common uses for email filters include organizing incoming email and computer viruses and removal of spam. As spammers periodically find new ways to bypass spam filte...

The joke, of course, refers to Spam, the canned food substance that originated in the 1930s in the United States, but was famously imported into Britain during World War II.1 Spam (spiced ham) became a cheap supplement for pure meat products, which were in severe shortage during the conflict. Perhaps the cheapness and mass consumption of Spam during the period are among the reasons why it becam...

The spam problem is getting worse all the time. In the paper, we propose Anti-Spam Grid, which can collaboratively filter spam messages by forming a virtual organization. We discuss the design of fuzzy CopyRank and distributed Bayesian algorithm, and describe the architecture of Anti-Spam Grid. A detailed analysis shows that the system is reliable, efficient and scalable, and an experiment show...

There are number of Anti-Spam filters that have reduced the amount of email spam in the inbox but the problem still continues as the spammers circumvent these techniques. The problems need to be addressed from different aspects. Major problem for instance arises when these anti-spam techniques misjudge or misclassify legitimate emails as spam (false positive); or fail to deliver or block spam o...

Email spam filters are commonly trained on a sample of recent spam and ham (non-spam) messages. We investigate the effect on filter performance of using samples of spam and ham messages sent months before those to be filtered. Our results show that filter performance deteriorates with the overall age of spam and ham samples, but at different rates. Spam and ham samples of different ages may be ...

BACKGROUND Unsolicited electronic mail (e-mail) is e-mail sent to a physician from a person unknown to the physician, who is seeking professional help. The purpose of this project was to analyze unsolicited e-mails sent to a digital textbook author to: 1) characterize the e-mails, 2) determine what resources would be necessary to answer the e-mails, and 3) propose a standard approach to reply t...
