Summer 2002 Workshop  Focus: Advanced QUestion and Answering for INTelligence (AQUAINT) program  Unsolved Q&A Challenges: -Temporal Analysis - Generating a sequence of events along an evolving timeline; resolving temporal references across a series of sources. -Multiple Perspectives - Handling multiple answers to questions from multiple sources with different (e.g., political, operational) perspectives. -Re-use of accumulated knowledge - Maintaining prior knowledge (questions and answers) to help answer the same question later. -Habitability - How can a question & answer system tell a user what it can do and fail gracefully.

Sorry, Officer, I didn't realize my radar detector wasn't plugged in. 9. Hey, you must've been doin' about 125 mph to keep up with me. Good job! 8. Do you know why you pulled me over? Okay, just so one of us does. 7. I thought you had to be in relatively good physical condition to be a police officer. 6. Gee, Officer! That's terrific. The last officer only gave me a warning, too! 5. I was trying to keep up with traffic. Yes, I know there are no other cars around. That's how far ahead of me they are. 4. Are You Andy or Barney? 3. Aren't you the guy from the Village People? 2. You're not gonna check the trunk, are you? 1. I can't reach my license unless you hold my beer. (OK in Texas) 12. When the Officer says "Gee Son....Your eyes look red, have you been drinking?" You probably shouldn't respond with,"Gee Officer your eyes look glazed, have you been eating doughnuts?" I pay your salary!
