Braun, SimoneSchmidt, Andreas2017-04-152017-04-152008Competence Management approaches suggest promising instruments for more effective resource allocation, knowledge management, learning support, and human resource development in general. However, especially on the level of individual employees, such approaches have so far not been able to show sustainable success on a larger scale. Piloting applications like expert finders have often failed in the long run because of incomplete and outdated data, apart from social and organizational barriers. To overcome these problems, we propose a collaborative competence management approach. In this approach, we combine Web 2.0-style bottom-up processes with organizational top-down processes. We addressed this problem as a collaborative ontology construction problem of which the conceptual foundation is the Ontology Maturing Process Model. In order to realize the Ontology Maturing Process Model for competence management, we have built the AJAX-based semantic social bookmarking application SOBOLEO that offers task-embedded competence ontology development and an easy-to-use interface.enontology maturingpeople taggingcollaborative competence managementsemantic social bookmarkingSOBOLEOText
