Abstract

The objective of this paper is to help users navigate for additional information for more comprehension of events in video through an explanation-on-demand hypervideo system. Given an XML database consisting of MPEG-7 video annotations and ontologies specifying relationships among events in annotations, the system is responsible for dynamically identifying hyperlinks inside a video that users possibly follow to clarify the points they do not understand. Three types of hyperlinks that are helpful in enhancing user comprehension of events are proposed: context, precondition and causal, which are based on an analysis of Fellbaum's verb entailments [4].
