Wikis are social web sites enabling a potentially large number of
articipants

to modify any page or create a new page using their web browser.
s

they grow, wikis suffer from a number of problems (anarchical structure,
arge

number of pages, aging navigation paths, etc.). We believe that semantic
ikis

can improve navigation and search. In SweetWiki we investigate the
se of semantic

web technologies to support and ease the lifecycle of the wiki. The
ery

model of wikis was declaratively described: an OWL schema captures
oncepts

such as WikiWord, wiki page, forward and backward link, author, etc.
his ontology

is then exploited by an embedded semantic search engine (Corese).
n

addition, SweetWiki integrates a standard WYSIWYG editor (Kupu) that
e

extended to support semantic annotation following the "social tagging"
pproach

made popular by web sites such as flickr.com. When editing a page,
he

user can freely enter some keywords in an AJAX-powered textfield
nd an

auto-completion mechanism proposes existing keywords by issuing SPARQL

queries to identify existing concepts with compatible labels. Thus
agging is

both easy (keyword-like) and motivating (real time display of the
umber of related

pages) and concepts are collected as in folksonomies. To maintain
nd reengineer

the folksonomy, we reused a web-based editor available in the underlying

semantic web server to edit semantic web ontologies and annotations.

Unlike in other wikis, pages are stored directly in XHTML ready to
e served

and semantic annotations are embedded in the pages themselves using
DF/A.

If someone sends or copy a page, the annotations follow it, and if
n application

crawls the wiki site it can extract the metadata and reuse them.
