It is already realized that we have entered the knowledge era: A time when the economic value of knowledge has become greater than the value of physical products. In this context, Knowledge Management (KM), i.e. the combination of management principles and technology that seeks to improve the performance of individuals and organizations by maintaining and leveraging the value of knowledge assets, has emerged into a managerial megatrend. We present the foundational concepts of Knowledge Management and based on them we argue that information plays an important role to the creation of new knowledge and to its dissemination. The importance of information is also revealed by existing approaches to KM, like knowledge-based systems. We investigate however, the domain of Information Filtering (IF) and its pottential application to KM. The foundations of IF are discussed in conjunction with the more traditional technologies of Information Retrieval and Text Categorization. A number of existing IF systems and agents are then presented from the point of view of KM. We distinguish between systems that have the ability to adapt, systems that have the ability to evolve and finally systems that combine global evolution with local learning. Keywords: Knowledge management, information retrieval, text categorization, term weighting, information filtering, intelligent information agents, adaptation, evolution.

Future Internet is...

With over a billion users, today's Internet is arguably the most successful human artifact ever created. The Internet's physical infrastructure, software, and content now play an integral part of the lives of everyone on the planet, whether they interact with it directly or not. Now nearing its fifth decade, the Internet has shown remarkable resilience and flexibility in the face of ever increasing numbers of users, data volume, and changing usage patterns, but faces growing challenges in meetings the needs of our knowledge society. Globally, many major initiatives are underway to address the need for more scientific research, physical infrastructure investment, better education, and better utilisation of the Internet. Within Japan, USA and Europe major new initiatives have begun in the area.

To succeed the Future Internet will need to address a number of cross-cutting challenges including:

Scalability in the face of peer-to-peer traffic, decentralisation, and increased openness

Trust when government, medical, financial, personal data are increasingly trusted to the cloud, and middleware will increasingly use dynamic service selection
