    Architecture framework for higher-level activity support using multiple functional workspaces on the desktop
    (WM2009: 5th conference on professional knowledge management, 2009) Grebner, Olaf
    Today's desktop systems face two major drawbacks in supporting the KWer. First, on workspace-level there is insufficient support for a KWer's higherlevel activities. Second, on information level, the KWer's personal information is scattered across the desktop and its applications. We analyze that state-of-the-art research suggests using multiple functional workspaces and recommends an underlying common abstract information model. However, research hasn't yet shown an integrated architecture for realizing multiple workspaces on such a common abstract information model. We present an architecture framework for realizing higher-level activity support using multiple functional workspaces on the desktop and position it as alternative to current desktops. We propose to base these functional-oriented workspaces on a common personal information model which itself is maintained as service. Using the Nepomuk 1Social Semantic Desktop as example for a service-oriented desktop architecture, our approach represents an evolutionary architecture in contrast to more radical, but not commercially implemented research approaches.

    Personal Process & Tool Self-Assessment – Triggering Structured Self-Improvement
    (Interaktive Kulturen : Workshop-Band : Proceedings der Workshops der Mensch & Computer 2010 - 10. Fachübergreifende Konferenz für Interaktive und Kooperative Medien, DeLFI 2010 - die 8. E-Learning Fachtagung Informatik der Gesellschaft für Informatik e.V. und der Entertainment Interfaces 2010, 2010) Grebner, Olaf
    In this paper we discuss an idea for a framework that enables a knowledge worker (KWer) on the one hand to evaluate her own personal processes and tools and on the other hand to identify improvement options for herself in a structured endeavor. We show this using the example of meetings. A KWer working, e.g., in international research projects spends 10% of the overall work time on meeting management, i.e., not dealing with the content but administrating meetings like, e.g., writing, formatting and sending out meeting minutes. However, a situation analysis of several KWers in the research domain shows us that a number of inefficiencies do exist which lead to an overall sub-optimal personal process. Our framework enables the KWer to assess her personal productivity situation by using a checklist with common process inefficiencies, e.g., major inefficiencies in meeting management are process loops and media breaks. The KWer then leverages a set of guided procedures to identify potential options for getting help to improve the personal situation. These guided procedures consist on the one hand of accessing the personal social network and on the other hand a structured problem resolving approach helps the KWer to apply best practice process knowledge and suitable tools to identified inefficiencies. Thus, the KWer can quickly identify suitable contacts or articles to improve the personal process on her own.
