A crowdsourcing framework for the management of mobile multimedia nature observationsA crowdsourcing framework for the management of mobile multimedia nature observations Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-022014enThis paper aims to describe MoM-NOCS, a Framework and a System that support communities with common interests in nature to capture and share multimedia observations of nature objects or events using mobile devices. Design/methodology/approach – The observations are automatically associated with contextual metadata that allow them to be visualized on top of 2D or 3D maps. The observations are managed by a multimedia management system, and annotated by the same and/or other users with common interests. Annotations made by the crowd support the knowledge distillation of the data and data provenance processes in the system. Findings – MoM-NOCS is complementary and interoperable with systems that are managed by natural history museums like MMAT (Makris et al., 2013) and biodiversity metadata management systems like BIOCASE (BioCASE) and GBIF (GBIF) so that they can link to interesting observations in the system, and the statistics of the observations that they manage can be visualized by the software. Originality/value – The Framework offers rich functionality for visualizing the observations made by the crowd as function of time.http://creativecommons.org/licenses/by/4.0/International Journal of Pervasive Computing and Communications310216-238 Christodoulakis Stavros Χριστοδουλακης Σταυρος Giannis Skevakis Chrisa Tsinaraki Ioanna Trochatou Emerald The MoM-NOCS functionality
