  abstract = "Third-person fictional narrative text is composed not only of
              passages that objectively narrate events, but also of passages that
              present characters' thoughts, perceptions, and inner states.  Such
              passages take a character's <I>psychological point of view</I>.  A
              language understander must determine the current psychological point
              of view in order to distinguish the beliefs of the characters from the
              facts of the story, to correctly attribute beliefs and other attitudes
              to their sources, and to understand the discourse relations among
              sentences.  Tracking the psychological point of view is not a trivial
              problem, because many sentences are not explicitly marked for point of
              view, and whether the point of view of a sentence is objective or that
              of a character (and if the latter, which character it is) often
              depends on the context in which the sentence appears.  Tracking the
              psychological point of view is the problem addressed in this work.
              The approach is to seek, by extensive examinations of naturally
              occurring narrative, regularities in the ways that authors manipulate
              point of view, and to develop an algorithm that tracks point of view
              on the basis of the regularities found.  This paper presents this
              algorithm, gives demonstrations of an implemented system, and
              describes the results of some preliminary empirical studies, which
              lend support to the algorithm.",
