Tentative Schedule – Spring 2020

  • January 16: Janine Siewert, Kaisla Kajava and Anna Dmitrieva
    • 3 short presentations about new members in our team, their background and what they will be working on
  • January 30: Umut Sulubacak: The Case for Context in Machine Translation for Subtitling: A Public Dissection
  • February 6: Aina Garí Soler: Teaching BERT the meaning of words
    • Since its appearance about a year ago, BERT has revolutionized the field of NLP. Its good performance on a wide range of NLP tasks has motivated numerous works aiming at better understanding its inner workings or at improving the learned representations.
      Capturing word usage in context, contextualized representations have attracted a lot of interest in the field of computational semantic analysis as well. However, a closer inspection of word similarity estimations provided by BERT reveals that they are not as semantic as one would expect, but are instead heavily influenced by surface structure-related properties.
      In this talk, I will present our ongoing work where we propose a number of strategies for improving BERT’s meaning representation of words in context. We intervene directly at the input and classification head levels of the model, or perform an additional fine-tuning step. An evaluation of our models on three semantics-related datasets shows an occasional moderate improvement over the standard pre-trained BERT. Finally, I will discuss a variety of directions that we believe promising to pursue in future work, as well as the main challenges faced during our experiments.
