New forms of conceiving the web such as web 2.0 and the semantic web have
emerged for numerous purposes ranging from professional activities to leisure.
The semantic web is based on associating concepts with web pages, rather than
only identifying hyperlinks and repeated literals. ITACA is a project whose aim
is to add semantic annotations to web pages, where semantic annotations are
Wikipedia URLs. Therefore, users can write, read and vote on semantic annotations
of a webpage. Semantic annotations of a webpage are ranked according
to users' votes. Building upon the ITACA project, we propose a transparent,
reputation-based architecture. With this proposal, semantic annotations are
stored in the users' local machines instead of web servers, so that web servers
transparency is preserved. To achieve transparency, an indexing server is added
to the architecture to locate semantic annotations. Moreover, users are grouped
into reputation domains, providing accurate semantic annotation ranking when
retrieving annotations of a web page. Cache copies of semantic annotations in
annotation servers are done to improve eficiency of the algorithm, reducing the
number of sent messages.
