The assessment of our psychological traits is a useful tool when we require them to simulate empathy. Since the creation of social media platforms, numerous studies dealt with measuring personality traits by gathering users\u2019 information from their social media profiles. Real world applications showed how natural language processing combined with supervised machine learning algorithms are effective in this field. These applications have some limitations such as focusing on English text only and not considering polysemy in text. In this paper, we propose a multilingual model that handles polysemy by analyzing sentences as a semantic ensemble of interconnected words. The proposed approach processes Facebook posts from the myPersonality dataset and it turns them into a high-dimensional array of features, which are then exploited by a deep neural network architecture based on transformer to perform regression. We prove the effectiveness of our work by comparing the mean squared error of our model with existing baselines and the Kullback\u2013Leibler divergence between the relative data distributions. We obtained state-of-the-art results in personality traits estimation from social media posts for all five personality traits.<\/jats:p>","DOI":"10.3390\/info11040179","type":"journal-article","created":{"date-parts":[[2020,3,31]],"date-time":"2020-03-31T13:27:19Z","timestamp":1585661239000},"page":"179","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Multilingual Transformer-Based Personality Traits Estimation"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8009-1082","authenticated-orcid":false,"given":"Simone","family":"Leonardi","sequence":"first","affiliation":[{"name":"Department of Control and Computer Engineering (DAUIN), Politecnico di Torino, Corso Duca degli Abruzzi, 24, 10129 Turin, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3821-5379","authenticated-orcid":false,"given":"Diego","family":"Monti","sequence":"additional","affiliation":[{"name":"Department of Control and Computer Engineering (DAUIN), Politecnico di Torino, Corso Duca degli Abruzzi, 24, 10129 Turin, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0083-813X","authenticated-orcid":false,"given":"Giuseppe","family":"Rizzo","sequence":"additional","affiliation":[{"name":"LINKS Foundation, Via Pier Carlo Boggio, 61, 10138 Turin, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7362-906X","authenticated-orcid":false,"given":"Maurizio","family":"Morisio","sequence":"additional","affiliation":[{"name":"Department of Control and Computer Engineering (DAUIN), Politecnico di Torino, Corso Duca degli Abruzzi, 24, 10129 Turin, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"127","DOI":"10.1007\/s13222-016-0221-x","article-title":"On Textual Analysis and Machine Learning for Cyberstalking Detection","volume":"16","author":"Frommholz","year":"2016","journal-title":"Datenbank-Spektrum"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"43","DOI":"10.1016\/j.cobeha.2017.07.005","article-title":"Detecting Depression and Mental Illness on Social Media: An Integrative Review","volume":"18","author":"Guntuku","year":"2017","journal-title":"Curr.
