Knowledge management is a large multidisciplinary field having its roots in Management and Artificial Intelligence. Activity of an extended organization should be supported by an organized and optimized flow of knowledge to effectively help all participants in their work. We have the pleasure to invite you to contribute to and to participate in the conference "Knowledge Acquisition and Management" and 2nd Workshop on “Artificial Intelligence for Knowledge Management” (KAM&AI4KM'14). The predecessor of the KAM conference has been organized for the first time in 1992, as a venue for scientists and practitioners to address different aspects of usage of advanced information technologies in management, with focus on intelligent techniques and knowledge management. In 2003 the conference changed somewhat its focus and was organized for the first under its current name. Furthermore, the KAM conference became an international event, with participants from around the world. In 2012 we’ve joined to Federated Conference on Computer Science and Systems becoming one of the oldest event. The “Artificial Intelligence for Knowledge Management” Workshop was initiated by IFIP Group TC12.6 in 2012 as the separate event during European Conference on Artificial Intelligence in Montpellier (ECAI’2012). From the beginning the workshop aims in bringing together researchers and practitioners involved in Knowledge Management using the methods and techniques of AI for building and improving all aspects of KM and of knowledge flow, among others, improvement of the innovation process. This year both teams KAM and AI4KM, have decided to join efforts in the FedCSIS framework with common challenge: “Collaborative Human-Machine Intelligence” under IFIP supporting. The aim of this common event is to create possibility of presenting and discussing approaches, techniques and tools in the knowledge acquisition and other knowledge management areas with focus on contribution of artificial intelligence for improvement of human-machine intelligence and face the challenges of this century. We expect that the conference&workshop will enable exchange of information and experiences, and delve into current trends of methodological, technological and implementation aspects of knowledge management processes.
