Community-aware semantic multimedia tagging : from folksonomies to commsonomies

Tagging is an extremely popular mechanism in many Web 2.0 applications to create metadata supporting search and retrieval of arbitrary multimedia information like digital images, video or audio. However, compared to the syndicated multimedia information itself, the metadata are still “sticky”. They cannot be accessed across several Web 2.0 applications, their semantic enrichment is not possible and they cannot be embedded in the local practices of communities of practice. Here, we present a multimedia tagging mechanism based on the international standard MPEG-7 for community-aware, standard compliant tagging of semantically enriched metadata implemented in the M7MT proof-of-concept application. -- Multimedia management ; MPEG-7 ; web-services ; information systems
