Anaphora resolution in text animation

For effective text animation from natural language stories, the source sentences in natural language should be processed not only individually but also as a coherent story as a whole. In particular, it is important that anaphoric expressions are interpreted adequately, since they provide crucial clues for the overall behaviors of story line characters. In text understanding, the task of anaphora resolution has been primarily on nominal expressions. In text animation, however, there are many other important candidates for anaphoric expressions, including those for actions and events, in addition to objects. In this paper, we provide an analysis of sample fairy tales, and present a classification for the types of anaphoric expressions for text animation. We also describe an implemented text animation system with anaphora resolution.
