Abstract. This paper formally specifies a document model for office information systems, including formal definitions of document types (frame templates), a document type hierarchy, folders, and folder organizations.Folder Organizations are defined using predicates and directed graphs. A Reconstruction Problem for folder organizations is then formulated; viz., under what circumstances it is possible to reconstruct a folder organization from its folder level predicates. The Reconstruction Problem is solved in terms of such graph-theoretic concepts as Associated Digraphs, transitive closure, and redundant/nonredundant filing paths. A Transitive Closure Inversion algorithm is then presented which efficiently recovers a Folder Organization digraph from its Associated Digraph.
Abstract. This paper presents a predicate-driven document filing system for organizing and automatically filing documents. A document model consists of two basic elements: frame templates representing document classes, and folders which are repositories of frame instances. The frame templates can be organized to form a document type hierarchy, which helps classify and file documents. Frame instances are grouped into a folder on the basis of user-defined criteria, specified as predicates which determine whether a frame instance belongs to a folder. Folders can naturally organized into a folder organization which represents the user's real world document filing system. The predicate consistency problem is discussed to eliminate two abnormalities from a folder organization: inapplicable edges (filing paths) and redundant folders. An evaluating net (including an association dictionary, an instantiation component and a production system) is then proposed for evaluating whether a frame instance satisfies the predicate of a folder during document filing. And the concept of consistency a rule base is also discussed.
