Abstract

A story segment retrieval device for a multimedia computer system storing a multimedia signal including a video signal, an associated audio signal and text information as a plurality of individually retrievable story segments, each having associated therewith a finite automaton (FA) model and keywords, at least one of which is associated with each respective node of the FA model. Advantageously, the story segment retrieval device includes a device for selecting a class of FA models corresponding to a desired story segment to thereby generate a selected FA model class, a device for selecting a subclass of the selected FA model class corresponding to the desired story segment to thereby generate a selected FA model subclass, a device for generating a plurality of keywords corresponding to the desired story segment, a device for sorting a set of the story segments corresponding to the selected FA model subclass using selected keyframes, keywords and query video clips to retrieve ones of the set of the story segments including the desired story segment. Multimedia signal parsing, video story segmentation, and video story categorization methods and corresponding systems, as well as storage media storing computer-readable instructions for performing these methods, are also described.
