Fraudulent e-wallet deposit notification SMSes designed to steal money and goods from m-banking users have become pervasive in Namibia. Motivated by an observed lack of mobile applications to protect users from such deceptions, this study evaluated the ability of machine learning to detect the fraudulent e-wallet deposit notification SMSes. The naïve Bayes (NB) and support vector machine (SVM) classifiers were trained to classify both ham (desired) SMSes and scam (fraudulent) e-wallet deposit notification SMSes. The performances of the two classifier models were then evaluated. The results revealed that the SVM classifier model could detect the fraudulent SMSes more efficiently than the NB classifier.

Η μεγαλύτερη πρόκληση των σύγχρονων υπολογιστικών συστημάτων είναι αναμφισβήτητα η αποδοτική αποθήκευση και ανάκτηση πολύ μεγάλου όγκου δεδομένων. Η ανάγκη αυτή έκανε την εμφάνισή της τα τελευταία χρόνια λόγω της έκρηξης δεδομένων που παρατηρείται στο διαδίκτυο και αποκτά ολοένα και μεγαλύτερη σημασία λόγω του πολύ μεγάλου εύρους πληροφοριών που μπορούμε να αντλήσουμε. Ο τομέας της υγειονομικής περίθαλψης και των ιατρικών δεδομένων είναι συνεχώς και ταχέως εξελισσόμενος. Η αξιοποίηση των Big Data στο χώρο της υγείας προσφέρει πολύτιμη πληροφόρηση καθώς παρουσιάζουν απεριόριστες δυνατότητες για αποτελεσματική αποθήκευση, επεξεργασία, sql queries και ανάλυση ιατρικών δεδομένων.Σκοπός της παρούσας διατριβής είναι η μελέτη τεχνικών εξόρυξης γνώσης για δεδομένα μεγάλου όγκου, που αφορούν το πεδίο της Υγείας. Παράλληλα σκοπός της έρευνας είναι η μελέτη στατιστικών και υπολογιστικών αλγορίθμων ανάλυσης μεγάλου όγκου δεδομένων υγείας που έχουν ως αποτέλεσμα την παραγωγή νέας γνώσης καθώς και την εξαγωγή στατιστικά σημαντικής πληροφορίας για τους επαγγελματίες υγείας. Τέλος, η παρούσα διατριβή διερευνά τις γνώσεις των επιστημόνων της Πληροφορικής Υγείας και των επαγγελματιών υγείας σχετικά με τα Big Data.Στην παρούσα διδακτορική διατριβή έγινε βιβλιογραφική ανασκόπηση της έννοιας των Big Data. Η ανασκόπηση αυτή περιλαμβάνει τον ορισμό των Big Data ,τα χαρακτηριστικά τους, τα πλεονεκτήματα και τα μειονεκτήματά τους στο χώρο της υγείας. Στη συνέχεια γίνεται αναφορά στην υλοποίηση και στους μηχανισμούς αποθήκευσης των Big Data. Επιπλέον γίνεται αναφορά στα συστήματα ανάλυσης και επεξεργασίας μεγάλου όγκου δεδομένων, στις γλώσσες προγραμματισμού για Big Data, στην εξόρυξη γνώσης δεδομένων στο χώρο της υγείας. Ακόμη γίνεται αναφορά στη χρήση των Big Data στην Ευρώπη και στον κόσμο. Τέλος παρουσιάζονται οι βασικές αρχές του GDPR καθώς και το πώς σχετίζεται με τα Big Data στο χώρο της υγείας. Επίσης διεξήχθησαν δύο εμπειρικές μελέτες.Η πρώτη μελέτη είχε σαν στόχο την καταγραφή της άποψης των επιστημόνων της Πληροφορικής Υγείας σχετικά με την τεχνολογία των Big Data. Η συλλογή των δεδομένων έγινε με χρήση ερωτηματολογίου. Η στατιστική ανάλυση έδειξε τη θετική ανταπόκριση του δείγματος σχετικά με την τεχνολογία των Big Data.Η δεύτερη μελέτη είχε σαν στόχο την καταγραφή της άποψης των Επαγγελματιών Υγείας σχετικά με την τεχνολογία των Big Data. Η συλλογή των δεδομένων έγινε με χρήση ερωτηματολογίου. Η στατιστική ανάλυση δεν έδωσε επαρκείς απαντήσεις καθώς οι ερωτηθέντες έδειξαν θετική στάση απέναντι στα Big Data ενώ απάντησαν ότι δεν γνωρίζουν πολλά για τη συγκεκριμένη τεχνολογία.Το τελευταίο κομμάτι της διατριβής περιλαμβάνει την ανάπτυξη μεθόδων πρόβλεψης για την δυνατότητα διάγνωσης των ασθενών με καρδιαγγειακά νοσήματα. Οι μέθοδοι πρόβλεψης που χρησιμοποιήθηκαν είναι: Λογιστική Παλινδρόμηση, Naive Bayes Classifier, Δένδρα αποφάσεων, Αλγόριθμος Κ κοντινότερων γειτόνων, Αλγόριθμος SVM (Support Vector Machine) και Random Forest. Η ανάπτυξη περιλάμβανε όλα τα στάδια προεπεξεργασίας των δεδομένων ενώ χρησιμοποιήθηκαν συγκεκριμένες μετρικές για τη μέτρηση της απόδοσης των κατηγοριοποιητών. Τέλος έγιναν βελτιώσεις της απόδοσης των κατηγοριοποιητών χρησιμοποιώντας διασταυρωτική επαλήθευση με την μέθοδο cross-validation ενώ επιλύθηκε και το πρόβλημα της ανισορροπίας των κλάσεων χρησιμοποιώντας τη μέθοδο SMOTE.

Abstract   Technology implementation in the marketplace world has attracted the attention of researchers to analyze the reviews from customers. The Klik Indomaret application page on GooglePlay is one application that can be used to get information on review data collection. However, getting information on consumer’s opinion or review is not an easy task and need a specific method in categorizing or grouping these reviews into certain groups, i.e. positive or negative reviews. The sentiment analysis study of a review application in GooglePlay is still rare. Therefore, this paper analysis the customer’s sentiment from klikindomaret app using Naive Bayes Classifier (NB) algorithm that is compared to Support Vector Machine (SVM) as well as optimizing the Feature Selection (FS) using the Particle Swarm Optimization method. The results for NB without using FS optimization were 69.74% for accuracy and 0.518 for Area Under Curve (AUC) and for SVM without using FS optimization were 81.21% for accuracy and 0.896 for AUC. While the results of cross-validation NB with FS are 75.21% for accuracy and 0.598 for AUC and cross-validation of SVM with FS is 81.84% for accuracy and 0.898 for AUC, while there is an increase when using the Feature Selection (FS) Particle Swarm Optimization and also the modeling algorithm SVM has a higher value compared to NB for the dataset used in this study.   Keywords: Naive Bayes, Particle Swarm Optimization, Support Vector Machine, Feature Selection, Consumer Review.
