profiling (UCP), social networks- and blogspace analysis
(SNBA), and personalization based on user profiles (PM).
Moreover, a very important component of this prototype
is represented by the User and Social Information Storage
(USIS), where all dimensions of the user and community
profiles reside. The analysis results of the other offline
components building the Social Media Beta prototype are
stored in USIS as well and are later made available for personalized
search and recommendation methods.
In June 2008 PHAROS was selected ‘Project of the Month’ of
the Directorate General for Information Society and Media
of the European Commission and in October 2008, the first
version of PHAROS platform has been successfully released
and demonstrated in a live-demo at the ICT 2008 event in
Lyon. In December 2008, a prototype of spam detection,
trust and reputation is released. This prototype implements
algorithms developed by L3S to combat spam using social
media data. The Reference Reconciliation module, also the
responsibility of L3S, has been as well released in December
2008 and provides several advanced methods for identifying
near-duplicates inside PHAROS content.
