TOPICA: A Tool for Visualising Emerging Semantics of POIs based on Social Awareness Streams
نویسندگان
چکیده
Topica is an application that enriches the Social Web with semantic data, to enable collective perception of Points of Interest (POIs), which are human constructs that describe information about locations (e.g., restaurants, attractions, cities). Topica provides an extra layer of information, compared to existing applications for browsing POIs, by modelling hidden characteristics of POIs, by: (1) generating a Linked Data representation of the collective perception of a POI; (2) enhancing the POI representation by mashing up services that enrich the POI’s related entities; and (3) providing a visual representation of the POIs adapted to suit userand context-sensitive filters. Topica identifies topics relevant to a POI by extracting DBpedia categories from entities (e.g., People, Places) and keywords (e.g., Crete, Bonn) obtained from social awareness streams related to the POIs.
