Added Value of Sociofact Analysis for Business Agility
In: AAAI Spring Symposium Series, 2011

Abstract The increasing agility of business requires an accelerated adaptation of organizations to continuously changing conditions. Individual and organizational learning are prominent means to achieve this. Hereby learning is always accompanied by the development of knowledge artifacts. For the entire of learning and artifact development the term knowledge maturing has been introduced recently, which focuses on these three manifestations of knowledge: cognifacts, sociofacts, and artifacts. In this paper we will focus on sociofacts as the subject-bound knowledge manifestation of social actions. Sociofacts are rooted in respective cognifacts play an independent role due to their binding to collective actions and subjects. These are particularly difficult to grasp but play a decisive role for the performance of organizations and the collaboration in there.The presented paper approaches the notion of sociofacts, discusses them on a theoretical level and establishes a first formal notation for sociofacts. We use the case of a merger between two companies to describe the advantages of sociofact analysis for such process. Some sociofact related problems during a merger are described and possible solutions are presented. We identify technical approaches for seizing sociofacts from tool-mediated social interaction and discuss open question for future research.

PLME as a Cognitive Tool for Knowledge Achievement and Informal Learning
In: Tatnall, Arthur and Jones, Anthony (eds.): Education and Technology for a Better World, World Conference on Computer in Education vol. , Springer, 2009, pp. 378-387

Abstract Since 2003 the research on Personal Learning Environments has increased. These environments support problem based, situated and informal learning in social networks within organisations and educational institutions and in subject related communities. The EU project MATURE enhanced this idea with the concept of a Personal Learning and Maturing Environment (PLME), which shall support and foster learning and knowledge maturing. In this paper, we present a model that describes the maturing of knowledge and informal learning. Based on an example of changing a university study course, we present the personal, community and organisational perspective on knowledge maturing and informal learning. This leads to a derivation of requirements for a PLME implementation.

Concept of a Tool Wrapper Infrastructure for Supporting Services in a PLE
In: Schmidt, Andreas and Attwell, Graham and Braun, Simone and Lindstaedt, Stefanie and Maier, Ronald and Ras, Eric (eds.): 1st International Workshop on Learning in Enterprise 2.0 and Beyond, CEUR Workshop Proceedings vol. 383, 2008

Abstract As one of the most relevant way of learning after apprenticeship is the informal learning an implementation of a PLE should try to support the learner by mashing up services and tools of every day work, creates cross links between them and gives motivation and support for personal and individual style of learning. This paper presents implementations and ideas for the whole collection of necessary pieces of software to provide a PLE in a bottom up manner. A server implementation is introduced which is based on a SOA approach and which includes an extractor for metadata of file objects. This module is furthermore able to run a semantic analysis on unstructured texts which results in for example in high-quality keywords and identification of persons. Taking this as technical background the social functions are explained which are identified as the functions a PLE is supposed to provide more than any knowledge management or e-learning software. Closing, these functions are converted in ideas of possible implementations of tools and services, back up by graphical mock-ups.

KnowledgeBus – An Architecture to Support Intelligent and Flexible Knowledge Management
In: Creating New Learning Experiences on a Global Scale. Second European Conference on Technology Enhanced Learning, EC-TEL 2007, Crete, Greece, September 17-20, 2007. Proceedings., Lecture Notes in Computer Science vol. 4753, Springer, 2007, pp. 487-492

Abstract MoKEx (Mobile Knowledge Experience) is an international project series focusing on actual challenges in knowledge management and e-learning. The project series is in cooperation with universities and industrial partners in Germany and Switzerland and links communities of practice with the innovative approaches of learning communities. As a result of the recent execution of the project, an architecture was developed that supports the flexible connection of various independent knowledge systems via the so-called KnowledgeBus. This paper introduces the concept of Single Point of Information (SPI) and the KnowledgeBus itself.
