• The intentional aspect of discourse and dialog is crucial, because ____________ give us a way of evaluating the _______________________ of our plans.

The structure of plans

• Flesh out this plan for 'find out by asking' (role names should be consistent and make sense, but don't have to be identical to those used in the outline):

• What is the difference between a desire and an intention?

Text Planning

• Analysis of language is best characterized as a process of __________, while generation of language is best characterized as a process of __________.

Sentence generation

• Proceding from the logical forms to the surface realization favors an approach that takes a bottom-up, _________________ strategy. This allows us to choose the _____________________ of the sentence first to serve as the head then set subgoals to plan for generating the complements.

• Consider the definition of 'the':

  • lex:the
  • category: N/n1
  • constraints: n1 is [- det]
  • result: [{n1} & [+ det]]
  This can be seen as a _____________ for using 'the' to ___________________________________.

• Why are unification grammars sometimes called feature-based grammars?

Speech synthesis

• What makes speech synthesis harder than just running our voice recognition algorithm in reverse?
• What is the simplest (but not the best) strategy for selecting which words to stress when synthesizing a voice output?

• A Classification and Regression Tree (CART) can be used to provide a cascade of _____________, each one referring to a specific ___________ of the word, each decision point chosen to mimimize the ____________ with respect to a ________________.
