Future Work
- Use semantics to automatically generate selection rules
- Use PTB to find semantic pairs for (eg.) PP attachment.
- Use an ontology to deal with sparse data problems.
- Generate selection heuristics based on the ontology and the
pairs.
Backtracking. When do we backtrack? Why and how do we backtrack?
How does backtracking relate to truly ungrammatical sentences?
Integrate with neural network work.
