Keynote talks

Session K1, 26 Nov 9:00–10:00. Leon Derczynski

Making NLP Greener

We know our modern models are large - often too large - in NLP. We know we have a difficult task ahead in limiting the damage to our climate. This talk examines how and why NLP affects emissions, and presents practical steps at many stages of the processing and development cycle for reducing not only power and hosting bills but also our impact as researchers and practitioners in NLP.

Session K2, 26 Nov 17:30–18:30. Vera Demberg

How "rational" are humans during language production?

The rational speech act model (RSA) aims to explain language comprehension and production in terms of recursive reasoning about speaker and listener. A lot of the evidence for the RSA model comes from language games, where speakers and listeners interact and try to guess what the other is trying to say with an ambiguous referring expression, or to explain why a speaker uses a specific expression. It is however less clear how these results bear out for everyday language usage. In this talk, I will report on several studies that test for rational communication at the discourse level. The first series of experiments explicitly sets out to test predictions of the RSA theory for the production and interpretation of discourse connectives. We find that while our data is in line with RSA predictions in a game-like setting, the effects disappear when moving to more realistic designs. I will discuss the extent to which this null result may be due to the difficulty of computing discourse expectations. Secondly, I will report on a referring expression experiment during driving, where we find that speakers adapt their utterances only at the beginning of the experiment, and then stick to that strategy, without any evidence for fine-grained adaptation to the comprehension difficulty of the comprehender.

Session K3, 27 Nov 11:00–12:00. Raquel Fernandez

Interaction-driven linguistic conventions

Approaches in psycholinguistics and sociolinguistics have emphasised the link between semantic variation and lexical choice and the interaction between speakers – a view which is not common in mainstream Natural Language Processing. In this talk, I will focus on interaction-driven linguistic conventions at the level of communities and within single conversations. I will first present work on analysing semantic variation in online communities of practice, showing that community-specific variation is at play and can have an impact on language processing. I will then move on to two-person dialogue setups where lexical choice is driven by ad-hoc conventions and describe our recent work on generating referring utterances grounded in the conversational and visual context. I argue that computational models of interaction-driven linguistic conventions can help us to better understand the processes underpinning these phenomena in humans, as well as contribute to more robust language technology tools and to user adaptation in dialogue systems.

Accepted presentations

The presentations are divided into long and short talks. 

  • Long talks will be 20 minutes, plus up to 10 minutes for questions.
  • Short talks will be 10 minutes. Each short talk session is ended with a joint question and answer session of 20 minutes or more.
