"State of the Art and Vision for the Semantic Web"

In the past 10 years, Semantic Web has first gone from a vision to a hype and then to something pronounced dead.

Differences in the culture of different people were and still are one of the main reasons for travel to foreign countries. The question whether cultural differences are relevant for the construction of Geographic Information Systems is longstanding and is of increasing interest since geographic information is widely accessible using the web and users volunteer information to be included in the system. The review of how the question of cultural differences was posed at different times reveals a great deal about the conceptualization of GIS at different times and makes a critical review interesting...
