Abstract
A mechanism is provided for updating a knowledge base of a spam detection system for email messages. A first and a second email set of email messages related to a time window are created. The first email set comprises email messages currently classified as spam messages, the second email set email messages currently classified as non-spam messages. A natural language term that is not present in the knowledge base is extracted from one of the email messages contained in one of the two email sets. Based on a frequency of occurrence of the extracted term in email messages contained in one or more of the two email sets and based on whether the respective email messages are spam messages or non-spam messages, a score value of the extracted term is calculated. The extracted term and the calculated score value are stored into the knowledge base.
