Knowledge-based retrieval of office documents

Document classification and retrieval systems for office applications require knowledge management to describe the semantics of documents related to procedural and domain dependent aspects of the office work to be described: operational dependencies, documents relationships and references to regulations and laws are concepts which are not explicitly stated in the text. This paper presents a semantic model for office documents classification and retrieval based on knowledge representation of the office procedural environment and of the application domain. Navigation along knowledge networks for document retrieval and browsing is described.
