Abstract

Abstract. Spam is an abuse of messaging undesired by recipients. Those who send spam are called spammers.  Popularity of Twitter has attracted spammers to use it as a means to disseminate spam messages. The spams are characterized by a neutral emotional sentiment or no particular users’ preference perspective. In addition, the regularity of tweeting behavior periodically shows automation performed by bot. This study proposes a new method to differentiate between bot spammer and legitimate user accounts by integrating the sentiment analysis (SA) based on emotions and time interval entropy (TIE). The combination of knowledge-based and machine learning-based were used to classify tweets with positive, negative and neutral sentiments. Furthermore, the collection of timestamp is used to calculate the time interval entropy of each account. The results show that the precision and recall of the proposed method reach up to 83% and 91%. This proves that the merging SA and TIE can optimize overall system performance in detecting Bot Spammer.Keywords: bot spammer, twitter, sentiment analysis, polarity, entropy Abstrak. Spam merupakan penyalahgunaan pengiriman pesan tanpa dikehendaki oleh penerimanya, orang yang mengirimkan spam disebut spammer. Ketenaran Twitter mengundang spammer untuk menggunakannya sebagai sarana menyebarluaskan pesan spam. Karakteristik dari tweet yang dikategorikan spam memiliki sentimen emosi netral atau tidak ada preferensi tertentu terhadap suatu perspektif dari user yang memposting tweet. Selain itu keteraturan waktu perilaku saat memposting tweet secara periodik menunjukkan otomatisasi yang dilakukan bot. Pada penelitian ini diusulkan metode baru untuk mendeteksi antara bot spammer dan legitimate user dengan mengintegrasikan sentimen analysis berdasarkan emosi dan time interval entropy. Pendekatan gabungan knowledge-based dan machine learning-based digunakan untuk mengklasifikasi tweet yang memiliki sentimen positif, negatif dan tweet netral. Selanjutnya kumpulan timestamp digunakan untuk menghitung time interval entropy dari tiap akun. Hasil percobaan menunjukan bahwa precision dan recall dari metode yang diusulkan mencapai 83% dan 91%. Hal ini membuktikan penggabungan Sentiment Analysis (SA) dan Time Interval Entropy (TIE) dapat mengoptimalkan performa sistem secara keseluruhan dalam mendeteksi Bot Spammer.Kata Kunci:  bot spammer, twitter, sentiment analysis,  polarity, entropy

Abstract

Application of data grouping aims to group data unsupervised, in this study comparing the results of the grouping with the K mean clustering method, K Means ++ clustering method and the Scalable K Means ++ clustering method. Based on the test results by analyzing the iteration error value, the results of the analysis show that the K Means ++ clustering and Scalable K Means ++ clustering method will produce less error values when compared to the K Means Clustering method. The data used as the basis of analysis in this study is based on data from Posyandu Rajawali Singosari in Malang. The initial initialization value of the centroid can be determined or randomly and is very influential for the data grouping process. Calculation analysis program used scilab programming and the error results with the graph of the minimum value. Result in test data, error value test data 1 get Scalable K Means ++ clustering error minimum 0,07, test data 2 get error value minimum K Means ++ Clustering 0,15, test data 3 get error value minimum 0,005 at metode Scalable K Means Clustering, test data 4 get error value minimum 0,15 at K Means ++ Clustering.
