摘要：1 New trends created by Web 2.0
As ubiquitous networks advance and the range of
users rapidly expands, “Web 2.0,” a concept that constructs
a distinct brand new world web from the conventional
web (Web 1.0), is attracting much attention in a
viewpoint of focusing on the characteristics of the
Internet and using its inherent capabilities effectively. At
present, Web 2.0 does not refer to any specific service or
technology, nor is there a clear definition of the term.
However, in its theory, one can find a vision of new
socio-economic system which may be brought by the
progress in ubiquitous networks (Figure 1-4-1).
