Abstract
Everyone agrees that user interactions and social networks are among
the cornerstones of Web 2.0. Web 2.0 applications generally run in
a web browser, propose dynamic content with rich user interfaces,
offer means to easily add or edit content of the web site they belong
to and present social network aspects. Well-known applications that
have helped spread Web 2.0 are blogs, wikis, and image/video sharing
sites; they have dramatically increased sharing and participation
among web users. It is possible to build knowledge using tools that
can help analyze users’ behavior behind the scenes: what they do,
what they know, what they want. Tools that help share this knowledge
across a network, and that can reason on that knowledge, will lead
to users who can better use the knowledge available, i.e., to smarter
users. Wikipedia, a wildly successful example of web technology,
has helped knowledge-sharing between people by letting individuals
freely create and modify its content. But Wikipedia is designed for
people---today's software cannot understand and reason on Wikipedia's
content. In parallel, the semantic web, a set of technologies that
help knowledge-sharing across the web between different applications,
is starting to gain attraction. Researchers have only recently started
working on the concept of a semantic wiki, mixing the advantages
of the wiki and the technologies of the semantic web. In this paper
we will present a state-of-the-art of semantic wikis, and we will
introduce SweetWiki, an example of an application reconciling two
trends of the future web: a semantically augmented web and a web
of social applications where every user is an active provider as
well as a consumer of information. SweetWiki makes heavy use of semantic
web concepts and languages, and demonstrates how the use of such
paradigms can improve navigation, search, and usability.
