. Task-models are user-centered representations of goals and actions a user needs to perform in the context of information processing. They help to characterize tasks which might be fruitfully supported by current or future systems and therefore are promising aids for a deeper understanding of user activities in certain application domains. This paper presents a taxonomy for document analysis tasks which are relevant in particular in knowledge management and can potentially be aided by visual text-access technology. The task-model is developed in three steps: Selected domain-independent task-models from literature are condensed to form a theoretical basis for the development of a specialized model. Case studies concerned with different document analysis tasks as well as results of a survey in knowledge-intensive industries complete and optimize the specialized task-model for document analysis in knowledge management.
