Senja Pollak, PhD.
Biography:
I am an assistant professor of Language Technologies and work as a researcher at the Department of Knowledge Technologies, Jožef Stefan Institute (JSI). My research interests include natural language processing, text mining, corpus linguistics, and computational creativity. I also teach language technologies and computational creativity at the Jožef Stefan International Postgraduate School. From 2018 to 2019, I was a research fellow at the Usher institute of the University of Edinburgh.
I am the leader of national project CANDAS, co-leader of project RobaCOFI funded by AI4Media, and institutional lead of national projects SOVRAG, KOBOS, and FORMICA2. I was the coordinator of the H2020 project EMBEDDIA (12 partners, budget 3 mio eur, 2019-2022), led industrial projects with companies Kliping and Iolar, and participated in many European and national projects, including SAAM, MUSE, WHIM, ConCreTe, TermFrame, Janes.
I have served in conference organizing committees (co-chair of SLSP 2019, Hackashop on news media content analysis and automated report generation at EACL 2021, BSNLP at EACL 2021, Digital humanities and natural language processing at PROPOR 2020 …), program committees (ICCC, JTDH, SYNASC2021 …) or served there as a reviewer (LREC, ACL-IJCNLP 2021 …).
My work was published in several conferences and journals including Computational Linguistics, Computer Speech, and Language, Natural Language Engineering, Terminology, Language Resources and Evaluation, International Journal of Lexicography. For more details, check GoogleScholar.
I am (co-)supervising 7 PhD students (1 completed, 6 ongoing) and 3 MSc students (1 ongoing, 2 completed).
