Using Static Documents as Structured and Thematic Interfaces to Multimedia Meeting Archives

摘要

Static documents play a central role in multimodal applications such as meeting recording and browsing. They provide a variety of structures, in particular thematic, for segmenting meetings, structures that are often hard to extract from audio and video. In this article, we present four steps for creating a strong link between static documents and multimedia meeting archives. First, a document-centric meeting environment is introduced. Then, a document analysis tool is presented, which builds a multi-layered representation of documents and creates indexes that are further on used by document/speech and document/video alignment methods. Finally, a document-based browsing system, integrating the various alignment results, is described along with a preliminary user evaluation.
