Abstract. 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 document-
centered knowledge work raises, amongst others, two questions: i) How
can the acquisition of formal knowledge in such an environment be facili-
tated? ii) How can the potential complexity of formal annotations during
a document’s life and use cycle be adequately handled?
We present the Mymory workbench as an approach to tackle these chal-
lenges. 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 con-
text, thereby a situation-oriented structuring of the annotations is being
achieved which can be exploited in semantic search and adapted docu-
ment presentation. In the paper, the general approach and architecture
of the system is being described. Example use cases show how document-
centered knowledge work can look like in such an environment and give
an idea which services can be possible with contextualized fine-grained
