The world-wide-web (www)  is being envisioned and designed as a 'semantic network', to the point that we refer to it as 'semantic web', where semantics refers to the relationship between the meaning  of its nodes and arcs.  To date, many of the functional expectations of  the SW are yet to be fulfilled (large scale deployments, ability to extract meaning from context, to infer relationships etc).

Most of SW development is taking shape however, without enough considerations for 'human factors', and currently there is an urge for developing high level, knowledge management capabilities to leverage the potential of web based technologies, and semantic networks, that can be used by 'people' irrespective of their technical abilities
