We will start as always with a model of (mathematical) knowledge. You may know this picture from last year's talk where we looked at the mks. There we concentrated on the content/form debate, and were led to the conclusion that certain (higher/semantic) aspects of kwowledge were actually subjective and dependent on the social context (whatever this may be).

Probst et al. 1997: Glyphs Data Information Knowledge
From sheer volume of data to quality of data …
Semantic Services are understood as services that use reasoning about the formal objects introduced with the metadata to enhance the data
Semantic Interactions are those services that use reasoning about the metadata to enhance the interaction. “ We will distinguish between services enabled by semantic data (i.e., the ones that make the machine smarter), and interaction enabled by semantic data (services that make the interaction with the smarter machine smarter)”
The Semantic Web approach consists in enhancing resources into semi-formal ontologies and making use of resulting (semantic) services. The Semantic Illustration approach consists in complementing resources and making use of resulting (semantic) services and interactions
