【 摘 要 】

The recent evolution of the Web, now designated by the termWeb 2.0, has seen the appearance of a huge number of resourcescreatedandannotatedbyusers.Howevertheannotationsconsistonlyinsimpletagsthataregatheredin unstructured sets called folksonomies. The use of more complex languages to annotate resources and to define semantics according to the vision of the Semantic Web, would improve the understanding by machines and programs, like search engines,ofwhatisontheWeb.Indeedtagsexpressivityisverylowcomparedtotherepresentationstandardsofthe Semantic Web, like RDF and OWL. But users appear to be still reluctant to annotate resources with RDF, and it should be recognized that Semantic Web, contrary to Web 2.0, is still not a reality of today’s Web. One way to take advantage of SemanticWebcapabilitiesrightnow,withoutwaitingforachangeoftheannotationusages,wouldbetobeableto generate RDF annotations from tags. As a first step toward this direction, this paper presents a tentative to automatically convert a set of tags into a RDF description in the context of photos on Flickr. Such a method exploits some specificity of tagsusedonFlickr,somebasicnaturallanguageprocessingtoolsandsomesemanticresources,inordertorelate semantically tags describing a given photo and build a pertinent RDF annotation for this photo.
