Representation Issues in Multimedia Case Retrieval

Thomas R. Hinrichs, Ray Bareiss, and Brian M. Slator

Video stories are an effective way to teach complex subjects, but video is opaque to a computer program. To what extent must the content of such stories be represented? We present three issues in story indexing that affect the distinctions that must be drawn in story representation and illustrate these issues with examples from ORCA, a pedagogical case-retrieval system in the domain of organizational change.
