Typically like pornographic, fraudulent and gambling messages, spam displays content on a continuous basis without being asked and is often unwanted by the recipient. So an algorithm is needed to classify the SMS document. Naïve Bayes is a classification method that is quite popular in classifying a document. The disadvantage of the naïve Bayes algorithm is that there is no process to normalize the words in the SMS document to their basic word forms using the Damerau-Levenshtein Distance algorithm. The results of the algorithm also often give rise to a probability value of 0, so laplace correction / laplace smoothing is needed to avoid a probability value of 0 in the training data. Before doing text calculations, first go through preprocessing text starting from tokenizing, filtering, and stemming. Accuration value from this method is 91,5 %} }
