  1. What do you mean? Disambiguating Communicative Signals using Context Mark ter Maat 22-04-2008

  2. Track 1 For ‘official business’ Provide information about the official subject Complement and elaborate on this subject with non-verbal gestures Track 2 To regulate the conversation Take turn / request turn Show understanding Ask for attention … Communicative acts The division of communicative acts according to Clark1 1) Herbert H. Clark, Using Language, Cambridge University Press, 1996 Differentiating Communicative Signals using Context

  3. Functions Communicative function is the high-level intention of a communicative act A signal is the multi-modal behaviour used to express this function Differentiating Communicative Signals using Context

  4. Functions and signals Generation: Lots of studies determining best signals to use for expressing a function Detection: Observing signals and determining which communicative function were intended Problem: ambiguous signals My current research about disambiguating these signals using context Differentiating Communicative Signals using Context

  5. An example Information from: Paul Ekman, ‘About brows: Emotional and conversational signals’, In Human ethology: Claims and limits of a new discipline,169-202, Cambridge University Press, 1979 Differentiating Communicative Signals using Context

  6. Disambiguation of signals To find the functions behind the signals: look at the context Some examples • “But I really want that car for my birthday!” • “Why do you want to do that?” • “*nod* Uhuh” • I want number 2, (0.3) number 4, (0.3) and number 7 Differentiating Communicative Signals using Context

  7. Contextual elements The following (preliminary) list of useful context elements was created: • Speaker / Listener • Part of the sentence (beginning, middle, end) • Surrounding signals (e.g. a nod combined with a smile and an “uhuh”) • The previous sentence type (e.g. a question or an offer • Part of the dialogue (beginning, middle, end) • Semantics Differentiating Communicative Signals using Context

  8. Conclusions I am currently working on this topic to get more contextual elements • Literature • Study recordings • Study annotated corpora With more known contextual elements it will be easier to detect and understand conversational functions Differentiating Communicative Signals using Context
