Web 2.0 and Semantic web are complementary. Social web applications are intuitive and easy to
use, but have limited semantics, mainly based on user tagging and simple metadata. Semantic
web applications are based on sophisticated data handling technologies, but are usually neither
usable nor user-friendly. Therefore, the integration of these technologies, that we call “intelligent
web”, has a great potential for supporting knowledge management and sharing. An example of an application where intelligent web tools are applied for knowledge creation, organization and
sharing is introduced in the next section, through the AWI environment.
