Information vs. Knowledge Management Information Management deals with handling information not necessarily bound to and interpreted by people. Knowledge Management supports knowledge work activities „a new type of intellectual work, that is about making sense, namely about turning information into knowledge through the interpretation of incoming highly non-standardized information for the purposes of problem solving and decision making. It is also about content creation: The generation of new knowledge to propell the innovation process of organizations.“ [Borghoff & Pareschi 98] U.M. Borghoff, R. Pareschi (Eds), Information Technology for Knowledge Management, Berlin, Heidelberg, New York, Springer, 1998.

Knowledge Types Explicit Knowledge Formal knowledge that can be packaged as information Reports, articles, manuals, patents, pictures, images, video, sound, software, organizational charts, process maps, mission statements, domains of expertise, etc. Tacit Knowledge Personal knowledge embedded in individual experience and shared and exchanged through direct face-to-face contact

Collective Memory Application Goals Support of knowledge lifecycle and conversion processes by Development of new knowledge based on creative ideas Goal: Innovation Securing new and existing knowledge Goal: Reuse, i.e., Learning Active knowledge distribution Goal: Information Connecting the available knowledge in new products and services Goal: Combination / Exploitation

Architectural Concepts: Collective Memories, Virtual Information and Knowledge Environments Collective Memories are Integrated Information, Content, and Knowledge Repositories, i.e., web based distributed information systems which enable the corporate as well as the personal and cooperative acquisition, management, access, distribution and usage of information and personalized content and knowledge. Virtual Information and Knowledge Environments are user interface front-ends for naive users to Internet-based information, content and knowledge management systems. They apply real world as well as abstract metaphors and information visualization layouts to provide a very natural means of interaction. In using these means a visually direct-manipulative and very often collaborative information dialogue paradigm can be supported at the user interface level.

Collective Memories and Virtual I&K Environments, Summary of R&D Challenges Externalize and Structure Implicit Knowledge, i.e., digitize descriptions of current creative potential Open Up Contents of Existing Explicit Knowledge Discover Hidden Knowledge Monitor and Manage User Information Need and Expertise Profiles, i.e., foster creative „matchmaking“ Design Open Architectures for CMs integrated by Virtual Information and Knowledge Environments Develop Integrated I&K Visualization and Interaction Models Evaluate Integrated I&K Visualization Distribution Mechanisms Implement and Test Scalable I&KVIS Architectures Provide Efficient Authoring, Configuration, and Maintenance Tools for I&KVIS

Virtual I&K Environments, i.e., „Virtual Collaboratories“ Distributable, shareable, scalable collaborative visually-directmanipulative I&K access support user adaptive through I&K user profiles Expected Results

Perspectives into Future R&D Work (Strategic Level) Efficient and flexible integration of multimedia information, content, and knowledge management, multimedia access functions, and corresponding meta data management into existing approaches of Digital Library and Media Archive Collections, i.e., Collective Memories Integration of visually-directmanipulative Virtual I&K Environments supporting semantical and cognitive efficient Information and Knowledge acquisition, access, enrichment, usage and collaboration within user interfaces to Collective Memories
