A graph is the most common method of visualizing a semantic web. However, when dealing with large and complex semantic webs, existing systems face challenges such as slow loading times and too much information being displayed on the screen. This paper introduces a Multimodal Semantic Browser (MMSB) that allows users to visualize and navigate through semantic webs with millions of triples. In addition, the Browser also recognizes the type of content that the user has selected and chooses the best modality and application to display that content in addition to a graph display.
With the advent of more light-weight technologies for connecting contents and functions provided by diverse application systems, called mashups, also individuals with their personal knowledge environments can benefit from arranging services flexibly to help them fulfil their knowledge needs. These personal, collaborative initiatives are often associated with trial-and-error, grass-roots level approaches which need an organizational and technical infrastructure to guide them without loosing the momentum created in these fragmented knowledge management activities performed by individuals, communities or in projects in an organization. Based on a discussion of these issues, this paper outlines the foundations for a knowledge service governance model to guide these activities.
The knowledge maturing model views learning activities as embedded into, interwoven with, and even indistinguishable from everyday work processes. Learning is understood as an inherently social and collaborative activity. The Knowledge Maturing Process Model structures this process into five phases: expressing ideas, distributing in communities, formalizing, ad-hoc learning and standardization. It is applicable not only for content but also to process knowledge and semantics. In the MATURE IP two toolsets will be develop that support the maturing process: a personal learning environment and an organisation learning environment integrating the levels of individuals, communities and organisation. The development is guided by the SER theory of seeding, evolutionary growth and reseeding and is based on generally applicable maturing services.
Service oriented architectures (SOAs) are a new paradigm in IT-management. This paper presents an SOA-implementation in the intranet portal of a 520-employee research institute, which was launched to accompany parallel knowledge-management (KM) activities. Furthermore it explains the benefits of an SOA-based IT-landscape for KM-activities.
