In this paper, a novel method is presented to detect spam content on the web. It is based on classification and employs an idea from biology, namely, danger theory, to guide the use of different classifiers. The evaluation of content features of WEBSPAM-UK2007 data set using 10-fold cross-validation demonstrates that this method provides high evaluation criteria in detecting web spam.

Static NAT – Mapping an unregistered IP address to a registered IP address on a one-to-one basis. Particularly useful when a device needs to be accessible from outside the network.Dynamic NAT – Maps an unregistered IP address to a registered IP address from a group of registered IP addresses. Dynamic NAT also establishes a one-to-one mapping between unregistered and registered IP address, but the mapping could vary depending on the registered address available in the pool, at the time of communication....
