Abstract:
This paper presents the architecture and key enabling techniques of a combined information extraction and visualization system named VIZIPEN, for automatically generating multimedia presentations. The system generates multimedia presentations such as graphical animations from a presentation template database by replacing embedded multimedia objects and their properties as desired by its users. A multimedia information extraction agent automatically populates the database with content objects such as images, audio clips, video clips, graphic objects and other animations. A domain knowledge base provides the base queries for automatic search initiation. By means of a novel approach named “concept expansion”, the system can generate media queries and populate the content database prior to system usage. We employ both content and context analysis to enable indexing of multimedia elements found in large collections such as the World Wide Web.
