Abstract


The Semantic of grouping : things which were
previously unrelated are now connected with
others via the group.



GroupMe! :allows users to group and arrange
multimedia Web resources they are interested in.



The semantics of any user interaction is captured.



enhancement of search for tagged Web resources

Introduction


Web 2.0: intercreativity and collective
intelligence.


GroupMe!


users are able to build groups


the grouping and tagging activities produce RDF
descriptions


RDF content is given back to the Web

using
vocabularies like
FOAF
2
, RSS
3
, or DCMI element set.


overcome the gap between Web 2.0 and the
Semantic Web

Scenario

GroupMe! Folksonomies


A folksonomy is a tuple F := (U, T,R, Y,

)


a resource can either be a resource or a set of
resources


A group is a set of resources.


An extended folksonomy is a tuple F := (U, T,
˘ R, Y,

)


˘R = R

G


GroupMe! folksonomy is a tuple F := (U, T, ˘
R,G, ˘Y ,

)


˘ Y defines the extended tag assignment: ˘Y


U
×

T
×

˘R
×

G,

Presentation

Ontologies and Content Creation


Almost every user interaction with the GroupMe! systems implies the
creation of RDF content.



Such semantically enriched resources, which evolve naturally while users are
interacting with the GroupMe! system, can in turn be processed by other
systems via the GroupMe! API.

Questions


at the edge between Web 2.0 and
Semantic Web?



Is this kind of interaction enjoyable?
