Helping online communities to semantically enrich folksonomies

International audienceThis paper presents our approach to collaborative and semi- automated semantic structuring of folksonomies. Tags freely provided by users of online communities are not semanti- cally linked, and this hinders significantly the potentials for browsing and exploring these data. We propose a socio- technical system combining automatic handlings of tags, us- ing state of the art algorithm, and user friendly interfaces designed after a careful analysis of the usage of our target communities. Much like folksonomies, our socio-technical system lets each user maintain his own view while still ben- efiting from others contributions. As a complement to sim- ilar approaches, our approach supports conflicting point of views all along the life-cycle of semantically enriched folk- sonomies
