Technical Challenges
Extending the Limits of NLP based interactions
- Dealing with incomplete syntactic coverage
- Dealing with incomplete lexicon
- Capitalize on interactive nature of environment
Exploiting competing viewpoints
- Minsky: Without more than one way to look at a problem, you’ll get stuck.
- What to do about self-contradiction (reason maintenance)
Reasoning with heterogeneous representations
- We’d like to use all your stuff!
- Protocol of inference (e.g. Joshua, Josie, GFP)
Interacting with visual and linguistic inputs
- Main focus is mixture of simple diagrams and text
- Diagrams carry structure and context
- Language carries content
Forming Consensus among multiple knowledge contributors
- Deciding whether this is a conflict or not
- Use topology of representation to isolate differences
- Interact with contributors until converge
