This article proposes the document model of a hybrid knowledge-based document analysis system for business letters. The model combines requirements of object-oriented representation of both, documents as well as knowledge necessary for analysis tasks, and is based on the ODA platform. Model-driven document analysis increases the flexibility of a system because several analysis specialists can be used in co-operation to assist each other and to improve the results of analysis. The inherent modularity of the system allows for a reuse of knowledge sources and integral constituents of the architecture in other document classes such as forms or cheques.
