Classification of Personality Type by Typology Hippocrates - Galenus Using Hybrid Naïve Bayes Decision Tree Algorithm

lassification of Personality Types is an artificial intelligence system for determining personality types based on Typology of HIPPOCRATES - GALENUS which divides personality into 4 groups according to the names of fluids that have an influence on the human temperament, namely: yellow bile (choleris), black bile (Melancholy), mucus (Flegmatis), and blood (Sanguinis). Personality is very important to know every individual. This is useful so that each individual can develop their strengths, can know what the purpose of life. And realizes abilities, talents and knows how to use them to achieve that goal by knowing themselves. In addition, the limitations of space and time when it comes to consulting an expert in the field of psychology becomes a problem for someone to know the personality type. Because it takes extra effort and cost is quite expensive. In addition, the location of a psychologist is also a factor that makes the patient difficult to consult. Therefore this study was made to classify personality types easily by everyone. This study uses two methods namely Naive Bayes and Naive Bayes Decision Tree (NBDT). Naive Bayes is a simple probabilistic-based prediction technique based on Bayes's theorem application with the assumption of strong dependence. While NBDT is a combination of two algorithms namely Naive Bayes and ID3 Decision Tree. Based on the results of the trial, it was found that the classification of Naive Bayes reached an accuracy of 90%, while the accuracy of NBDT reached 83.33%.
