Compositionality

Getting the right contents.

• semantic capacity tested — knowing the propositional content
• operationalization — form => meaning mapping
• measure of success — generalizing to the right meaning representation for novel expressions (this is non-trivial; multiple compatible generalization maybe applicable depending on context)

task

Given that a model can map certain expressions to their meaning representations, can they also do this for new expressions?

results

• lexical generalization (fill in new words/pairs) isn’t too hard for new NN
