Our application aims at augmenting the WWW’2012 posters session. Targeted users are conference attendees owning a recent, internet-enabled mobile device. During the conference, each poster will be given a QRCode. Flashing that code (eventually inside the webapp for browsers that support device API or capture input type) leads to a poster homepage, which provides numerous services: (i) information access (associated metadata, published PDF file, video presentation if any…); (ii) navigation among metadata (following links on authors, publications and keywords), Metadata are accessed through SWDF and enriched by DBLP and DuckDuckGo!. During the navigation, users construct their own local ontology and classify it on client side using OWLReasoner JS engine; (iii) miscellaneous functions that will link posters metadata and user’s personal metadata storage (e.g. posters that may be of interest, vote for this poster, etc.).
