Publication Abstract Title Managing Sentence Planning Requirements Authors Eduard Hovy and Leo Wanner Abstract In this paper we focus on sentence planning (microplanning) as a distinct phase of the generation process, necessary to compute such aspects as sentence delimitation, sentence-internal organization, reference, etc. Treating each phenomenon as a separate planning task, we illustrate the need for a planning paradigm different from the traditional ones in (at least) this phase because of the complex interactions among these (semi-independent) subtasks. We describe our solution: a blackboard-based sentence planner, in which different subtasks are handled by independent modules that incrementally rewrite and flesh out a text structure (a set of partially specified input statement(s)) to form a fully specified list of sentence specifications.
