The use of semantic representations in document-oriented environments -as formal annotations or embedded instances of a formal knowledge base -is seen as an enabling technology for intelligent services which may help knowledge workers in tasks like finding, structuring, or assessing information. A very high level of formalization may even more directly support problem solving, e.g., by the application of inferencing services. A coupling of textual and formal representations in documentcentered

We present the Mymory workbench as an approach to tackle these challenges. Mymory is based on a semantic wiki system and supports manual as well as automated annotations of wiki documents. These annotations can be framed by automatically obtained models of the user's work context, thereby a situation-oriented structuring of the annotations is being achieved which can be exploited in semantic search and adapted document presentation. In the paper, the general approach and architecture of the system is being described. Example use cases show how documentcentered knowledge work can look like in such an environment and give an idea which services can be possible with contextualized fine-grained annotations.
