  1. The Importance of Being Importantfor Question Generation, that is … Lucy Vanderwende,Microsoft Research (USA)

  2. Machine Reading • How do you evaluate machine reading? • Ability to answer questions • Ability to ask questions • Graesser et al. (2005): QG is one salient manifestation of active learning and reveals how deeply the learner has mastered the material

  3. What/what are we developing question generation systems for? • Tutoring systems • Improved answer retrieval • Community question answers (Yahoo!, WikiAnswers, …) • Harabagiu et al. 2005, pre-generating questions to improve QA systems • Information discovery • Question schemas • Machine learning driven by posing questions: Ruminator, Ureel et al. 2005 • Need to identify which questions drive learning, and which are unproductive

  4. Microsoft? • Schwartz et al. 2004, developing automated learning aids, used full parsing + generation + summarization • “limiting/selecting questions created by Content QA Generator is difficult” • There is a tie between summarization and question generation • If you do summarization well, does that carry over to question generation? Is the core task of summarization easier to evaluate in the context of question generation? • Question generation might be a way to engage/entertain users in a search setting • Why are people still so enamored with Eliza-like technology? • What makes questions engaging vs. annoying? • We care about students! • Strongly agree that a shared task enhances visibility of the area and encourages participation from a wider audience • A well-defined shared task can let students shine • We are always looking for interns who have done innovative work 

  5. Plea for multi-sentence input • Question Generation shared task could provide a test-bed for other technologies • Anaphora resolution, mention detection, event detection, RST, cohesion, … • Designing the shared task to target these levels of analysis will also provide greater visibility to the NLG community • It is important to understand the phenomena in the test corpus • Vanderwende 2005, what syntax can contribute in entailment
