A multimedia document filing system

This multimedia document filing system employs a dual modeling approach. The dual model consists of a document type hierarchy and a folder organization. Document type hierarchy is used to specify document types based on the analysis of layout, conceptual and content structures, and users define their own folder organization, which is used to store frame instances and the high level conceptual information of documents. A storage architecture is presented to integrate the document type hierarchy, the folder organization and the original document storage as a three level storage system, which in turn supports effective document searches. Document retrieval can be conceptual-based or content-based. Users are allowed to specify criteria for governing the document filing. An agent-based architecture for implementing the folder organization and the basic operations for constructing and reorganizing a folder organization are proposed.
