Methods that don’t work well

• Maximizing coverage while minimizing ambiguity is inconsistent with symbolic NLP.

• Furthermore, hand-coding syntactic constraints and preference rules are time consuming to build, do not scale up well and are brittle in the face of the extensive use of metaphor in language.

• Example: if we code

animate being --> swallow --> physical object

I swallowed his story, hook, line, and sinker

The supernova swallowed the planet.
