ABSTRACT
In natural language generation, the use of a lexicalized grammar formalism
and incremental syntactic and semantic processing places strong and
specific constraints on the form and meaning of grammatical entries.
These principles restrict which grammatical representations are possible
and suggest examples an analyst can consult to decide among possibilities.
We discuss and justify a number of such constraints, and describe how
they inform the design of lexical entries for motion verbs. Our entries
allow a generator to match the lexical choices found in a target corpus
of action descriptions by assessing how the interpretation of a verb
in context contributes towards the hearer's identification of
the intended action.
