This work leverages machine-learning and deep learning to capture latent representations of clinical narratives, while using natural language processing during preprocessing to translate raw text into a lower-dimensional feature space. The approach aims to improve performance on clinical notes and enable reliable detection of concept labels, supporting more effective and personalized health services from routine narrative records.","Development of machine-learning-based natural language processing to detect concept labels in clinical narratives  \nby  \nThanh-Dung LE  \nMANUSCRIPT-BASED THESIS PRESENTED TO ÉCOLE DE TECHNOLOGIE SUPÉRIEURE  \nIN PARTIAL FULFILLMENT FOR THE DEGREE OF DOCTOR OF PHILOSOPHY  \nPh.D.  \nMONTREAL, SEPTEMBER 12, 2023  \nÉCOLE DE TECHNOLOGIE SUPÉRIEURE UNIVERSITÉ DU QUÉBEC  \n Thanh-Dung Le, 2023  \nThis Creative Commons license allows readers to download this work and share it with others as long as the author is credited.

While it’s difficult to express my sincere gratitude to them in words, I would like to take this opportunity to acknowledge their contributions.  \nFirst and foremost, I express my deepest gratitude to my principal supervisor, Professor Rita Noumeir, for her continuous guidance, motivation, and inspiration throughout my Ph.D. studies. Her invaluable advice and discussions during weekly meetings have positively impacted my research and career trajectory. I am also grateful for her support during the COVID-19 pandemic, where her instructions and supervision helped me adapt to remote working tools and maintain my research progress. I also thank my co-supervisors, Professor Phillipe Jouvet, for his valuable comments and feedback on my research manuscripts. I would also like to thank my Ph.D. assessment jury for their constructive feedback and support.  \nI thank Fonds de Recherche du Québec Nature et Technologies for awarding me the merit scholarship that enabled me to pursue my Ph.D. project. I also want to thank Pervasive and Smart Wireless Applications for the Digital Economy (PERSWADE) for their support during my research at The Énergie, Matériaux et Télécommunications center, Institut National de la Recherche Scientifique (INRS) . Additionally, I would like to thank the anonymous reviewers who provided valuable feedback on my research papers and helped improve my work’s quality.  \nI acknowledge my former supervisors and colleagues at the NECHPY-Lab, INRS: Professor Long Le, Dr. Ha Nguyen Vu, Dr. Hoang Duc Tuong, Dr. Tran Duy Thinh, Dr. Nguyen Ti Ti, Dr. Nguyen Minh Tri, Vu Huy Hoang, Phan Thanh Tung, Dr. Nguyen Minh Dat. Furthermore, I express gratitude to my colleagues at LATIS, ETS: Dr. Georges Matar, Jihad El Tannoury, Gloria Huong, Oussema, Haythem, Mario, Asheok, Wajahat, Khalil, Toufik, Clara, Emily, and many others for their support, encouragement, and the memories we have shared.  \nVI  \nFinally, I am indebted to my parents (Lam-Bup, Luyen-La), sisters (Hong Diem, Ngoc Trinh, Le Huyen), brothers (Quoc Vuong, Xuan Son), niece (Hong Vy), nephews (Gia Bao, Thien Phuc) for their unconditional love, support, and sacrifices. Their emotional and financial support have been invaluable during my Ph.D. journey. Special thanks to my wife and our little princess Nha Lam Cecilia, who has been with me every step of the way,
