Description

Various kinds of information can be acquired from social media platforms; one of them is on Twitter. User biographical
information and tweets are the essential assets for research that can describe the Big Five Personality, including openness,
conscientiousness, extraversion, agreeableness, and neuroticism. Several previous studies have tried the prediction of Big Five
Personality. However, the authors found problems in how to optimize the work of the personality prediction system. So, in this
study, Big Five Personality predictions were carried out on users of Twitter and improved the performance of the personality
prediction system. We implement optimization techniques such as sampling, feature selection, and hyperparameter tuning to
enhance the performance. This study also applies linguistic feature extraction, such as LIWC and TF-IDF. By using 287 Twitter
users that have permitted their data to be crawled acquired from an online survey using Big Five Inventory (BFI), and applying
all optimization techniques, the average accuracy result is 84.22% which is a 74.44% gain over the specified baseline.
