In order to summarize a story, it is necessary to access a high level analysis of the story that highlights its central concepts. A technique of memory representation based on plot units appears to provide a rich foundation for such an analysis. Plot units are conceptual structures that overlap with each other when a narrative is cohesive. When overlapping intersections between plot units are interpreted as arcs in a graph of plot units, the resulting graph encodes the plot of the (...) story. Structural features of the graph then reveal which concepts are central to the story, and which concepts are peripheral. Plot unit analysis is currently being investigated as a processing strategy for narrative summarization by both computer simulation and psychological experiments. (shrink)

The ability to answer questions about a text is the strongest possible demonstration of text comprehension. The question‐answering problems that arise in a story‐understanding system are discussed. Some solutions are described and illustrated by a computer program, which reads stories, and answers questions.
