Zhou, ChaoBénel, Aurélien2017-04-152017-04-152008Social tagging is intimately linked to ‘tag cloud’, the visualization apparatus which is intended to bring the ‘wisdom of crowds’.

We illustrate this apparatus on the collaborative analysis of a scientific archive.enVisual InterfacesWeb 2.0Social taggingScientific archivesQualitative analysisText
