Marius Popescu, Lecturer at the University of Bucharest, Department of Computer Science, since 2004.
Ph.D. in 2004 with the thesis "Machine Learning Applied in Natural Language Processing".
My domains of interest are: artificial intelligence, machine learning, computational linguistics, information
retrieval, authorship identification, computer vision. My achievements in these fields include: a new method
for automatic word sense disambiguation that was awarded third prize at the Senseval 3 evaluation exercises for
word sense disambiguation organized by ACL-SIGLEX in 2004; coauthor of the method ENCOPLOT for plagiarism detection
which won the first international competition in automatic plagiarism detection in 2009, followed by ranking 4th
at PAN@CLEF 2010 and 2nd at PAN@CLEF 2011; a method for authorship analysis which obtained the best results in the
author identification task at PAN@CLEF 2012;
Co-author of learning systems that ranked on 3rd place in the Native Language Identification Shared Task
of the BEA 8 Workshop of NAACL 2013, and on 4th place in the Facial Expression Recognition Challenge of
the WREPL Workshop of ICML 2013.
