Wikis have emerged as easy and flexible tools for accessing and
sharing knowledge on the internet and within organizations. Due
to their highly collaborative nature, users can typically modify
and create content without any access restrictions since these are
replaced by social practices. On the other hand, due to the lack of
central guidance, knowledge sharing is driven by the individual
choice of contributors. We claim that – especially in enterprise
settings – the lack of guidance for content creation is a major
problem. We therefore analyze search and knowledge sharing in
current Wikis. To improve knowledge sharing, we present the
Woogle concept, which introduces“Social Search” and “Need-driven Knowledge Sharing” into Wikis. We describe our
prototype implementation Woogle4MediaWiki and results from
initial evaluation studies.
