  1. GroupMe! - Where Semantic Web Meets Web 2.0 20071123 林光德

  2. 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

  3. 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 Webusing vocabularies like FOAF2, RSS3, or DCMI element set. • overcome the gap between Web 2.0 and the Semantic Web

  4. Scenario

  5. 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,

  6. Tag example • (gm:nicola, gm:jazz, gm:jazzLegendsGroup) • (gm:nicola, gm:musicians, gm:jazzLegendsGroup) • (gm:nicola, gm:trumpet, gm:chetBakerVideo, gm:jazzLegendsGroup) • (gm:nicola, gm:jazz, gm:chetBakerVideo, gm:jazzLegendsGroup) • (gm:nicola, gm:vocalJazz, gm:siljeNergaardPhoto, gm:jazzLegendsGroup)

  7. Search Strategies

  8. The GroupMe! System

  9. The GroupMe! System(cont.) • Creation of groups. • Search and navigation. • RDF export.

  10. The GroupMe! System(cont.) • Architecture • Aggregation • Model • User, Tag, Group, Resource • Application logic • Presentation

  11. 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.

  12. Questions • at the edge between Web 2.0 and Semantic Web? • Is this kind of interaction enjoyable?
