About
GroupMe! extends the idea of social tagging systems like del.icio.us, Flickr or BibSonomy by introducing the group dimension. The foundation of social tagging systems are so-called folksonomies, which describe how users (folks) tag resources (e.g. photos, videos, publications, etc.). In technical terms a folksonomy is just a collection of tag assignments:
(User, Tag, Resource) = User has tagged Resource with Tag at a particular time.
Over time it is likely that semantics emerge, e.g. tags that are often assigned to same resources may be synonyms. Hence, folksonomies are promising to improve (web) search, etc. With GroupMe!'s approach of taggable groups we extend tag assignments with a group dimension:
(User, Tag, Group, Resource) = User has tagged Resource with Tag in a certain Group at a particular time.
Benefits of the GroupMe! approach:
- improved foundation for search and ranking strategies (e.g. handling of un-tagged resources, see red resource in foigure below)
- improved foundation to learn relations between tags (see figure below)
- improved foundation to bridge from folksonomies to ontologies (e.g. more precise relations between tags + RDF descriptions of resources)
