Today, semantic annotation creation is a well known bottleneck in semantic applications for enterprises. On the other hand semantic technologies have already proven to facilitate, e.g., a more efficient information management especially for knowledge workers (KWs). We pursue in this paper the central idea of using task management as a means for extracting semantic annotations out of the daily work activities in a way that is associated with minimal effort for the KW. To ensure the success of such an approach, a broad acceptance of the task management application by the KWs is a precondition. For this, we present the KASIMIR prototype that embeds task management into the daily work activities of a KW. It facilitates the creation of semantic annotations in form of attributes as well as relations between tasks, users and information objects such as emails, websites, documents, etc. in a manner that is seamlessly integrated into the KW’s work activities. To this end we integrate task management plug-ins into desktop applications, e.g., emails clients and web browsers. These plug-ins interact with a sidebar that creates a consolidated overview of existing tasks and their rela- tions. The underlying infrastructure of the Nepomuk Semantic Desktop 1 leverages semantic web technologies to ensure the efficient management of semantic data. 1 Introduction In this paper we show how a task management system can leverage semantic web technologies to support Knowledge Workers (KWs) more efficiently. Knowledge work essentially consists of the organization of information objects (IOs) on the desktop but of course also in the actual work with these objects [Py05]. According to [Bo04] we call these supporting and production activities, respectively. Supporting activities are largely related to Personal Information Management (PIM) [Be04], which plays a decisive role in knowledge work.
