In the version of this article initially published, there were some errors in Section III, Methods and Section VI, Conclusions. In Preprocessing of Methods, there is a sentence “The informal words may be in the form of slang words or abbreviations that are often used in daily life like cp at (from “cepat” or fast), blum (from “belum” or not yet), and gak (from “tidak” or no).”. The correct sentence is “The informal words may be in the form of slang words or abbreviations that are often used in daily life like cpat (from “cepat” or fast), blum (from “belum” or not yet), and gak (from “tidak” or no).”. In Text Classification of Methods, there is a sentence “Where P(B|A) is the probability of B appearance when A is known? The value P(A|B) is the probability of an appearance if B is known. P(A) is the probability of an appearance, while P(B) is the probability of B appearance.”. The correct sentence is “Where P(B│A) is the probability of the appearance of B when A is known. The value of P(A|B) is the probability of the appearance of A if B is known. P(A) is the probability of the appearance of A, while P(B) is the probability of the appearance of B.”. In Conclusions, a sentence “The accuracy reaches 93.42%; using 25% features with highest TF-IDF” should be changed to “The accuracy reaches 93.65%; using 25% features with highest TF-IDF” based on the results in Fig.3. These errors have been corrected in the PDF versions of the article.
