The Human Semant c Web
The research of the KMR group revolves around a structured information architecture
called a knowledge manifold (KM) (Naeve, 1997, 1999, 2001b) which supports a
number of different strategies for the suppression and presentation of information. A
KM consists of a number of linked information landscapes (contexts), where one can
navigate, search for, annotate, and present all kinds of electronically stored information.
A KM is constructed by conceptual modeling of a specific knowledge domain
in order to capture its underlying thought patterns in the form of context maps.
By defining a conceptual model (ontology), the concepts acquire an outside and
an inside. In fact, a single concept acquires several outsides, since it can appear in
several different contexts. In KM terms, we make the following:
Definition: Let C denote a concept. An outside of C is called a context for C, and
the inside of C is called the content of C.
