Abstract
In text generation, various kinds of choices need to be decided. In conventional frameworks, which we callone-path generation frameworks, choices are made in an order carefully designed in advance. In general, however, since choices depend on one another, it is difficult to make optimal decisions in such frameworks. Our approach to this issue is to introduce the revision process into the overall generation process. In our framework, revision of output texts is realized as dependency-directed backtracking (DDB). As well as Justification-based Truth Maintenance System (JTMS), we maintain dependencies among choices in a dependency network.
