dc.description.abstractAnti-spam systems are software systems which filter spam e-mails. Spam e-mails are nowadays a serious problem which causes high losses to the institutions. This report proposes a new anti-spam prototype made up by three stages. The first, the pre-processing, analyses the e-mails to search for known spam patterns, as well as performs eliminations or replacements to simplify the e-mails and to make them uniform. The second stage, the feature selection, identifies the most relevant features of the e-mails. The third stage, the classification, consists in an artificial neural model — the multilayer perceptron — to classify the e-mails. The anti-spam prototype is exhaustively tested on three public corpora — SpamAssassin, LingSpam and Trec 2007 — available in the Internet. The prototype performance is assessed according to the percentage of correct classifications in both e-mail classes — legitimate (ham) and spam. It is also assessed the time spent in training and testing of the neural model. The results obtained are very promising. The anti-spam prototype has very good performance on the three corpora.pt_BR
