  1. Paradigms, Corpora, and Tools in Discourse and Dialog Research Panel at SIGDial 2003 Janyce Wiebe University of Pittsburgh

  2. Pragmatic Aspects of Discourse and Dialog • Attitude and affect (subjectivity, emotion, opinion, …) • Time (tense, aspect, temporal coherence) • Style

  3. Attitude and Affect in Discourse • Question answering systems should distinguish between factual and speculative answers • Multi-perspective QA aims to present multiple answers based on opinions from various sources • Multi-document summaries should summarize multiple views • “Camps” in on-line discussions and finding reviews • Adapting dialog managers when problematic emotions in task-oriented dialogs • Adapting pedagogical strategy when positive or negative emotions in tutorial systems

  4. Annotation and Corpora • Corpus annotated for subjectivity (emotions, evaluations, speculations) in text • Recent work annotating emotions in dialog • Synergy between text and dialog • Research direction: integrating work in the two modalities
