SMS Spam Detection and Filtering of Transliterated Messages

SMS spam has seen an exponential increase in the past few years. This is a pain for mobile users, since any important message often gets lost in the pile of spam messages. SMS spam detection is at a very nascent stage when it comes to implementing in user devices, although there has been research in the field for a long time. We have carried out a survey of the work that has been done in the field of SMS spam filtering, and we have identified certain features which give high accuracy when classifying SMS spam.
