In this paper, we explore some of the apparent problems in adopting semantic technologies for content management and investigate a methodology and a tool to overcome these barriers. Our approach tries to benefit from both the networked collective intelligence of social software and the obvious need for methodologies and well-defined explicit semantics in(More)
Business models on the basis of digital content require sophisticated descriptions of that content, as well as service-oriented carrier architectures that allow to negotiate and enforce contract and license schemes in heterogeneous digital application environments. We describe Knowledge Content Objects (KCO), that provide expressive semantic descriptions of(More)
We report on a standardized container object called Knowledge Content Object for the management of rich media content which is enhanced by representations of domain knowledge. KCOs are based on the Information Object Design Pattern originally developed for the DOLCE foundational ontology. We describe a methodology for stepwise refinement of the domain(More)
We explored how the intended purpose of a knowledge model can influence the modelling process and in particular, how it impacts on the choice points of the underlying modelling methodology. We introduce a classification of knowledge models according to their intended scope, expressiveness and degree of acceptance. As a result, we aim to define critical(More)
This paper surveys various semantic enhancement approaches and techniques in order to answer on demands of today’s massive and heterogeneous, Web-based Content Management Systems (CMS). Furthermore, this paper transfers results and shares our experiences in field gained through the development of the Interactive Knowledge Stack (IKS) (the EU FP7 IKS(More)
The building of interoperable knowledge based multimedia information systems requires a dialog between those research communities that make advances in content classification through e.g. image analysis, those working on standardisation of multimedia meta data, e.g. the MPEG community and those working on advanced knowledge-based end user applications that(More)
In this short paper we report on a semantic model for content and knowledge which distinguishes between three descriptive levels: information relating directly to the resource, to the meta data of the resource, and to the subject matter addressed by the content. This model addresses five fundamental requirements for automation: formality, interoperability,(More)
We present the results of a European research project which developed specifications for so-called Knowledge Content Objects (KCO) and for an attendant infrastructure, the Knowledge Content Carrier Architecture (KCCA). The work addresses the problem that while there are many standards for content and for meta data, there is at present, no suitable framework(More)
