Planning in AI and Text Planning in Natural Language Generation

Researchers in natural language generation are becoming increasingly aware of the similarities between the task of planning the content and structure of the natural language text and that of other AI planning tasks. The problem of text planning and other AI planning problems have been studied separately from each other, and while many overlapping results have been found, they have not been shared as often. The purpose of this paper is to explore the similarities between the two areas of research by reviewing the problems and solutions of each in order to gain a better insight into how needs in one area can benefit from results in another.
