Is it the end of Word Sense Disambiguation as we know it?


Word Sense Disambiguation (WSD) is a fundamental problem in Natural Language Processing and in particular in Natural Language Understanding. In this seminar, I will be discuss how recent advances in word and sense embedding have contributed to redefining the WSD task. In particular I will present a new framework (Tripodi and Navigli, 2019) for WSD, based on game-theoretic principles (Tripodi and Pelillo, 2017), that can be used with arbitrary word and sense representations and a new disambiguation technique (Loureiro and Jorge 2019; Hu, Li, and Liang 2019) that inspired the title of this talk.

Rocco Tripodi is postdoctoral researcher at Ca’ Foscari University of Venice, under the ODYCCEUS project (odycceus.eu). He completed his PhD in Computer Science at Ca' Foscari in 2015 with a thesis titled "Evolutionary Game Theoretic Models for Natural Language Processing". He is also Adjunct Professor at Ca' Foscari where he teach/has taught Computational Linguistics and Digital Text Analysis. His research interests are in the areas of machine learning and natural language processing. In particular, he is interested in learning models based on game theoretic principles and on the design, learning and evolution of linguistic communication systems.
