4. Our Approach to Low Cost MT Apply new machine learning techniques that require –less development data –shorter development time –less specialized human expertise

5. Our Approach to Low Cost MT Use multi-engine architecture to –flexibly make use of whatever resources are available data: Generalized EBMT human consultants: automatic elicitation human experts: knowledge-based MT –Tap the strengths of different approaches to MT.

8. Version Space Abstraction Lattice

9. Scientific Challenges of NICE Automatic linguistic elicitation from native speakers: –bottom up: from small phrases to larger constructions –interrogation intermingled with confirmation of induced grammatical rules

10. Scientific Challenges of NICE Transfer rule induction: –version space learning: hone in on the right level of generalization –take advantage of expected constituents, e.g., ART-N but not V-ART –only local optimality is guaranteed –converges faster: no worst case exponential problem
